Lents: Caius and Christ’s [Stoat]

Alas, I missed Caius retaking the Men’s headship on Thursday, mostly because I didn’t think it would happen (they were nowhere on Wednesday) but partly because I was bag-carrying for King’s, who rewarded me with an exciting bump on (LoL)Catz and ensuing chaos; and on Christ’s on Friday. But I did see Christ’s take the Women’s headship from Emma, somewhat to my surprise, though Kate says they listen to her. Anyway, here it is:



(it doesn’t happen till 4:40, do feel free to skip ahead).

Leonard Nimoy Has Died [EvolutionBlog]

Sad news:



Leonard Nimoy, the sonorous, gaunt-faced actor who won a worshipful global following as Mr. Spock, the resolutely logical human-alien first officer of the Starship Enterprise in the television and movie juggernaut “Star Trek,” died on Friday morning at his home in the Bel Air section of Los Angeles. He was 83.


His wife, Susan Bay Nimoy, confirmed his death, saying the cause was end-stage chronic obstructive pulmonary disease.



Leonard Nimoy has the distinction of having starred in two of the greatest television series ever. Let us recall that he went straight from Star Trek to Mission: Impossible, where he basically saved the show after the seemingly irreplaceable Martin Landau left.


Come to think of it, he was also the special guest bad guy in another of the greatest television series ever: Columbo. Here’s the whole episode. Skip ahead to the one hour mark and watch for three minutes to see one of my all-time favorite scenes.






He will be missed.

Slushy wave off coast of Nantucket

As you well know if you live there, the eastern United States has been in a deep freeze throughout February, 2015. Wave after wave of ice and snowstorms have hit the region, and NASA says that hundreds (maybe thousands) of records have been set for daily low temperatures. Now, from a photographer and surfer in Nantucket, Jonathan Nimerfroh, we have this amazing photo from February 20, 2015 of an ocean wave, just before it freezes solid. He calls it a slurpee wave.


The New York Times has a great article about this photo and these slow-moving waves of slush. Jonathan’s photo has also been on the Weather Channel and other places (I first saw it on Facebook; thanks, Beverly Spicer!). Nimerfroh told the New York Times:



I just noticed a really bizarre horizon. The snow was up to my knees, getting to the water. I saw these crazy half-frozen waves. Usually on a summer day you can hear the waves crashing, but it was absolutely silent. It was like I had earplugs in my ears.



Of course, the ocean does freeze. Salty sea water has a lower freezing point than the ice in your home freezer, not 32 degrees F but instead about 28.4 degrees F. And it was colder than that on that day in Nantucket, somewhere around 10 degrees F. Still, these waves are something very special, and even experts commented that they had not seen them before. Helen Fricker, a glaciologist at the Scripps Institution of Oceanography in La Jolla, California, who studies the dynamics of ice flows in Antarctica, told the New York Times that a full scientific explanation was “outside her expertise.” Erin Pettit, a glaciologist at the University of Alaska, Fairbanks, added that waves in Alaska tend to break up sea ice and said:



I have never seen frozen waves like this.



Nimerfroh said he returned the following day to the same beach. That day it was a few degrees colder still and the water had completely frozen. He said:



Nothing was moving. There were no waves anymore.

Moon between Gemini stars and Procyon on February 28


Tonight’s bright waxing gibbous moon – February 28, 2015 – will be bright enough to erase many stars from the blackboard of night. Even so, three stars should be brilliant enough to withstand tonight’s moonlit glare – the Gemini stars, Castor and Pollux, plus Procyon the Little Dog Star. In late February and early March, the moon passes south of Castor and Pollux, and north of Procyon, the brightest star in the constellation Canis Minor the Lesser Dog.


And there’s one more object you’re sure to notice near the February 28 moon. That dazzling object to the east of tonight’s moon is the planet Jupiter. The king planet is far brighter than any star (except our sun). Jupiter will follow the moon, Castor, Pollux and Procyon westward across the sky, until the moon and three accompanying stars set in the west during wee hours of the morning on March 1.

The dark side of the waxing moon always points eastward or in its direction of travel.

Valentines day (night), red eye flight back to Perth.


I had another go at night shots out the plane window … this time under very dark no moon conditions.

Amazingly, the Alpha Centaurid meteor shower was also active!


Apologies for the excessive noise. Due to plane motion and minor turbulence, I couldn’t expose for much longer than 1 second and keep the stars sharp. Notwithstanding, it is quite amazing that modern day cameras can capture so much detail in 1 second on a no moon night.

Friday Cephalopod: Cephalove [Pharyngula]

Now you can learn everything you need to know about octopus sex. It’s a bit tangly:


algaeoctos


But just in case you got lost in all the tentacles, here’s a diagram to help you out. By the way, in case you’ve ever wondered where an octopus keeps its nads, they’re maybe not where you expected.


octosex


There should be a warning sign here, though.



In one instance, she and her colleagues observed two day octopuses mating on a reef in Indonesia. After about 15 minutes of copulation, the female lunged and wrapped two arms around the male’s bulbous body, his mantle. A few minutes later, the male was motionless. The female then carried the corpse to her den, where he presumably became dinner.


In another instance, researchers watched a large female day octopus off the coast of Micronesia. A small male mated with her a dozen times. But then the male went in for a 13th mating session, and the female turned on him. She strangled him and took him back to her den to feed on over the course of the next two days.



So octopuses are all feminists, then?

King v. Burwell: Supreme Court case could wreak havoc on working families, state governments and health providers [The Pump Handle]

“Established by the state.” Those are the four words at the center of an upcoming Supreme Court case that could strip affordable health insurance coverage from millions of working families and result in billions of dollars in uncompensated care costs.


The case is known as King v. Burwell and at its core is the question of whether residents who live in states with federally administered health insurance marketplaces, versus state-run marketplaces, are eligible to receive insurance subsidies. The plaintiffs in the case claim that those four little words in one section of the entire Affordable Care Act — “established by the state” — mean that Congress never intended for federal subsidies to be available to people living in states where the feds set up the health insurance exchange. (A little background: As authorized in the ACA, the federal government will set up an exchange in a state where state lawmakers choose not to do so on their own.)


However, legal observers and advocates argue that the plaintiffs are simply taking the words out of context and if one looks at the ACA as a whole, it’s clear that Congress intended all Americans to have access to federal subsidies and thus, affordable health insurance. The Supreme Court is scheduled to hear arguments in the case next Wednesday.


“The motivation is to undermine the ACA and the system that sets it up,” Sarah Somers, managing attorney at the North Carolina office of the National Health Law Program and an attorney with the Network for Public Health Law, told me. “This was a legal theory that was designed to bring this litigation. …It doesn’t make any sense that Congress would put that kind of poison pill in the legislation. Why would they do that?”


This is the language that’s in question — it’s known as Section 36B of the Internal Revenue Code as authorized by the ACA: the monthly premiums for such month for 1 or more qualified health plans offered in the individual market within a State which cover the taxpayer, the taxpayer’s spouse, or any dependent (as defined in section 152) of the taxpayer and which were enrolled in through an Exchange established by the State under 1311 of the Patient Protection and Affordable Care Act…


But in examining references to the exchanges within the ACA’s thousands of pages, it’s clear that the concepts of a state-administered exchange and the federal exchange are interchangeable, Somers said. In an amicus brief that the National Health Law Program signed onto along with AARP, Services and Advocacy for Gay, Lesbian, Bisexual and Transgender Elders, and the National Council On Aging, the authors noted:



Petitioners’ acontextual interpretation of a single phrase in one provision of the Act—if accepted—will make insurance unaffordable in the 34 states that use the Federally Facilitated Exchanges, harming low- to moderate-income residents of those states. It would also render meaningless other key provisions of the ACA designed to increase access to affordable health insurance for all.



Somers said a Supreme Court ruling in favor of the plaintiffs could have a “massive impact — it’ll affect millions of people and will cause incredible difficulty, if not chaos, for federal governments, state governments and the insurance companies.” So, just how many people are at risk for losing subsidies in the 34 states that now depend on federally facilitated health insurance marketplaces? According to a map from the Kaiser Family Foundation, more than 13 million Americans estimated to benefit from subsidies in 2016 could be impacted, with the numbers ranging from about 32,000 residents in Alaska to more than 784,000 residents in Georgia to more than 1.7 million in Texas.


“It’s amazing to think what a wreck this would be,” Somers told me.


Earlier this month, the Urban Institute released a report on what a ruling for the plaintiffs would mean for uninsured rates and health care spending. That report estimated that a ruling for the plaintiffs — a ruling that would prohibit federal subsidies in 34 states — would result in 8.2 million more uninsured people, including thousands of children, who would have otherwise spent more than $27 billion on health care in 2016. Without federal subsidies that enable people to buy affordable health coverage, the reports estimates that those newly uninsured would spend only $5.3 billion on health care, with another $12 billion provided in uncompensated care. (The uncompensated care estimate is based on the assumption that governments would fund such care and health care providers would make in-kind contributions at the same rates they had previously.)


However, the ACA was specifically designed with the assumption that demand for uncompensated care would go down — for example, the law reduced certain Medicare and Medicaid hospital payments that had historically gone to cover uncompensated care. Those types of funding reductions coupled with additional revenue losses resulting from a rise in the uninsured rate could be disastrous for providers. In addition, losing health insurance and the opportunity to access preventive care as well as care in the earliest stages of an illness has tragic effects on people’s health and mortality risks as well. In an amicus brief in support of the defendants, the American Public Health Association along with a host of deans, chairs and faculty within schools of public health write:



Because of the interrelationship between insurance coverage, health care access, and population health, a decision striking down the IRS rule (on federal subsidies) can be expected to lead to a loss of improvements in access to care, worsening health, and more preventable deaths. Applying the results of a prior study estimating mortality declines linked to the first four years of health reform in Massachusetts, a loss of health insurance by estimated 8.2 million persons can be expected to translate into over 9,800 additional deaths annually.



‘Sucker-punch to the gut of the middle class’


Linda Blumberg, an economist and senior fellow at the Urban Institute, described the plaintiffs’ arguments as “very flimsy,” as it seems clear that they’re taking the four words at the center of the case out of context. Blumberg was involved in the process of providing technical assistance to states as they decided whether to set up state-run exchanges or let federal officials take over. She told me that the question of whether that decision would jeopardize the availability of federal insurance subsides never came up — not once. If Congress had intended to use federal insurance subsidies as a way to pressure states into setting up their own exchanges and ultimately punish states that chose not to — as the plaintiffs argue — it’s incredible that no state took notice, she told me.


“You can’t create this coercive situation with very substantial consequences for a state without it being noticed,” said Blumberg, who also co-authored the Urban Institute report cited above. “It’s kind of impossible to have been part of the conversation around reform and believe that there’s legitimacy to this case. Having been a part of the policy process, I just don’t see any legitimacy in their argument whatsoever.”


In addition to an increase in the uninsured rate and uncompensated care, Blumberg explained how a ruling for the plaintiffs could upset the very foundation of the ACA, much of which builds off the premise of a mixed insurance pool of healthy and sick people. She said that if insurance subsidies disappear in states that depend on federally administered exchanges, the rise in some residents’ monthly insurance bills would exempt many from the ACA’s individual insurance mandate. That means some people could drop insurance coverage without facing a penalty. Blumberg said in that scenario, it’s likely that the first people who drop coverage will be healthy people — people who use the least amount of health care. That means that sicker people who use more health services remain in the insurance pool, which pushes premiums up. From there, it can be a domino effect — as premiums go up, more and more healthy people leave the insurance market and a primary mechanism for controlling health care costs starts to disappear.


“We have a situation in which we’ve created all these consumer protections that let everyone (access the insurance market), but if the only people coming in are sicker and more costly, you have a very bad dynamic,” she told me.


Regarding the four words at the core of King v. Burwell, Blumberg argued that for all intents and purposes, every exchange is established by the state — “regardless of the semantics over who’s doing the administrative role, all of these are exchanges established by the state by either the state setting it up themselves or by choosing to let the federal government set it up for them.”


“The legal folks that I listen to and trust seem cautiously optimistic and feel the case against the plaintiffs is incredibly strong on its merits,” Blumberg said.


Jane Perkins, legal director for the National Health Law Program, told me that the plaintiffs have to prove that the “statute is unambiguous on its face” and as a result, the IRS regulations about federal subsidies are beyond the agency’s authority. However, Perkins said that a hallmark of statutory construction is to determine the meaning of words by looking at the statute as a whole — in other words, you don’t untether a small group of words from its statutory context.


“The intent and wording throughout (the ACA) is to extend coverage to as many Americans as possible and the whole statute is set up to do just that,” Perkins said. “I think if the court ruled for the plaintiffs, it would not only upset (the entire) ACA, it would be reworking the rule of statutory constructions that has applied in cases for generations.”


Regarding the ruling’s potential impact, Perkins said “it would be a sucker-punch to the gut of the middle class if this ruling came down in favor these politically driven plaintiffs.” She noted that the great majority of those affected if subsidies go away would be working people. However, she also said that if the Supreme Court rules in the plaintiffs’ favor, Congress could still step in to fix the law’s language or help states convert as seamlessly as possible to state-operated insurance exchanges.


“But it would be a very bumpy road,” Perkins said.

(The uncompensated care estimate is based on the assumption that governments would fund such care and health care providers would make in-kind contributions at the same rates they had previously.)


However, the ACA was specifically designed with the assumption that demand for uncompensated care would go down — for example, the law reduced certain Medicare and Medicaid hospital payments that had historically gone to cover uncompensated care. Those types of funding reductions coupled with additional revenue losses resulting from a rise in the uninsured rate could be disastrous for providers. In addition, losing health insurance and the opportunity to access preventive care as well as care in the earliest stages of an illness has tragic effects on people’s health and mortality risks as well. In an amicus brief in support of the defendants, the American Public Health Association along with a host of deans, chairs and faculty within schools of public health write:



Because of the interrelationship between insurance coverage, health care access, and population health, a decision striking down the IRS rule (on federal subsidies) can be expected to lead to a loss of improvements in access to care, worsening health, and more preventable deaths. Applying the results of a prior study estimating mortality declines linked to the first four years of health reform in Massachusetts, a loss of health insurance by estimated 8.2 million persons can be expected to translate into over 9,800 additional deaths annually.



‘Sucker-punch to the gut of the middle class’


Linda Blumberg, an economist and senior fellow at the Urban Institute, described the plaintiffs’ arguments as “very flimsy,” as it seems clear that they’re taking the four words at the center of the case out of context. Blumberg was involved in the process of providing technical assistance to states as they decided whether to set up state-run exchanges or let federal officials take over. She told me that the question of whether that decision would jeopardize the availability of federal insurance subsides never came up — not once. If Congress had intended to use federal insurance subsidies as a way to pressure states into setting up their own exchanges and ultimately punish states that chose not to — as the plaintiffs argue — it’s incredible that no state took notice, she told me.


“You can’t create this coercive situation with very substantial consequences for a state without it being noticed,” said Blumberg, who also co-authored the Urban Institute report cited above. “It’s kind of impossible to have been part of the conversation around reform and believe that there’s legitimacy to this case. Having been a part of the policy process, I just don’t see any legitimacy in their argument whatsoever.”


In addition to an increase in the uninsured rate and uncompensated care, Blumberg explained how a ruling for the plaintiffs could upset the very foundation of the ACA, much of which builds off the premise of a mixed insurance pool of healthy and sick people. She said that if insurance subsidies disappear in states that depend on federally administered exchanges, the rise in some residents’ monthly insurance bills would exempt many from the ACA’s individual insurance mandate. That means some people could drop insurance coverage without facing a penalty. Blumberg said in that scenario, it’s likely that the first people who drop coverage will be healthy people — people who use the least amount of health care. That means that sicker people who use more health services remain in the insurance pool, which pushes premiums up. From there, it can be a domino effect — as premiums go up, more and more healthy people leave the insurance market and a primary mechanism for controlling health care costs starts to disappear.


“We have a situation in which we’ve created all these consumer protections that let everyone (access the insurance market), but if the only people coming in are sicker and more costly, you have a very bad dynamic,” she told me.


Regarding the four words at the core of King v. Burwell, Blumberg argued that for all intents and purposes, every exchange is established by the state — “regardless of the semantics over who’s doing the administrative role, all of these are exchanges established by the state by either the state setting it up themselves or by choosing to let the federal government set it up for them.”


“The legal folks that I listen to and trust seem cautiously optimistic and feel the case against the plaintiffs is incredibly strong on its merits,” Blumberg said.


Jane Perkins, legal director for the National Health Law Program, told me that the plaintiffs have to prove that the “statute is unambiguous on its face” and as a result, the IRS regulations about federal subsidies are beyond the agency’s authority. However, Perkins said that a hallmark of statutory construction is to determine the meaning of words by looking at the statute as a whole — in other words, you don’t untether a small group of words from its statutory context.


“The intent and wording throughout (the ACA) is to extend coverage to as many Americans as possible and the whole statute is set up to do just that,” Perkins said. “I think if the court ruled for the plaintiffs, it would not only upset (the entire) ACA, it would be reworking the rule of statutory constructions that has applied in cases for generations.”


Regarding the ruling’s potential impact, Perkins said “it would be a sucker-punch to the gut of the middle class if this ruling came down in favor these politically driven plaintiffs.” She noted that the great majority of those affected if subsidies go away would be working people. However, she also said that if the Supreme Court rules in the plaintiffs’ favor, Congress could still step in to fix the law’s language or help states convert as seamlessly as possible to state-operated insurance exchanges.


“But it would be a very bumpy road,” Perkins said.

Ask Ethan #77: Humans in the vacuum of space (Synopsis) [Starts With A Bang]


“A vacuum is a hell of a lot better than some of the stuff that nature replaces it with.” -Tennessee Williams



The depiction of dying in space — by exposure to its terrifying vacuum — is incredibly varied, from freezing to swelling and bulging to simply exploding.

For this week’s Ask Ethan, we take on the question of Kerrie Pinkney, who wants to know:



[W]ill you explode if exposed to the vacuum of space? I’ve gone down the “water boils in a vacuum then freezes” road, others have gone down the “tried it on a dog and it lived” approach. The movie Gravity shows buddy lifting his helmet and instantly freezing so… how does it work, Ethan?



So, who’s got it right?

This Is Not What I Want As a Defense of “The Humanities” [Uncertain Principles]

Yesterday was Founders Day at Union, celebrating the 220th anniversary of the granting of a charter for the college. The name of the event always carries a sort of British-boarding-school air for me, and never fails to earworm me with a very particular rugby song, but really it’s just one of those formal-procession-and-big-speaker events that provide local color for academia.


This year’s event started, as always, with a classical music performance– a song by Aaron Copeland, this time, so we’ve at least caught up to the 20th Century. (I’m not sure I want to live long enough to see a Bob Dylan number performed at one of these…) The main point, though, was the talk by Laura Skandera Trombley, president of Pitzer College, on The Enduring Value of the Humanities.


Working where I do, I’ve heard a lot of these sorts of talks, but I still don’t really know what I want from a defense of “the humanities.” I’m pretty sure, though, that this wasn’t it.


There was a lot to not like, starting with the traditional cherry-picking of statistics to show that there’s a crisis in “the humanities”– quoting the Huffington Post on the 50% decline in the number of students majoring in the humanities. Of course, as has been noted nearly as many times as that statistic has been thrown out is the fact that it’s garbage. The apparent big decline comes from careful selection of a starting point at the peak of a giant bubble in “humanities” enrollments inflated by Baby Boomers desperate to stay out of Vietnam.


More than that, though, there’s a bunch of baiting and switching going on here. The case for the value of “the humanities” basically boils down to “You like art, don’t you? Wouldn’t it suck if we didn’t have art?” But, you know, to the extent that there’s a genuine crisis going on, it’s not because anyone’s threatening to stop producing art. Times have never been better for the production of art– in fact, the real crisis facing people who make art is that there’s too damn much of it, driving prices down and making it increasingly difficult to make a living making art.


But when we talk about “the humanities” in an academic context, we’re not talking about people who make art– only a tiny fraction of people in “humanities” departments are engaged in that. To the extent that “the humanities” are under threat in academia, what’s threatened isn’t the production of art, but comfortable faculty positions in which people are paid to talk about art. Which is a very different thing. The production of art is doing just fine, it’s the dissection of art that needs defending. But we didn’t get that.


(To be fair, there’s an exact parallel to this tactic in the sciences. See, for example, this Daily Beast piece which could be snarkily summarized as “Why should we spend $10 billion on the Large Hadron Collider? Well, you like radio, don’t you?” I don’t like that version of it any more than I like this one.)


There’s also a little sleight-of-hand when it comes to the selection of examples. The two most detailed examples given are the works of Aristotle, and a quote from a T.S. Eliot poem used at the opening of a TV show. But again, this isn’t really what “the humanities” are these days– they’re just safe and lazy signifiers that everybody will agree are Important in a sort of abstract sense. But if you were to suggest that every student at the college needs to read Aristotle and Eliot, there would be a revolt among the faculty (not without justification, though that’s a separate culture war).


Even the obligatory list of dropped names of great works ends up having problems:



More than ever we seek ways to feel connected to one another, and in the end it doesn’t matter if it’s the beauty of Strauss’ flowing “An der schönen blauen Donau,” or Bill T. Jones’ exploration of survival through dance in Still/Here, or Auden’s incomparable “Lullaby,” “Lay your head my darling, human on my faithless arm,” or Maxine Hong Kingston’s anguished admission in Woman Warrior, “You must not tell anyone what I am about to tell you. In China your father had a sister who killed herself. She jumped into the family well,” or our poet-bard, Kanye West’s love song to Kim, “Bound to fall in love, bound to fall in love (uh-huh honey)”; these are all expressions and interpretations of life and they tie us to those who came before as well as to our contemporaries.



On the page, that looks better than it sounded live. In person, the Kanye West reference was really grating, as it was delivered in a very showy deadpan manner, to deliberately highlight the vapidity of those lyrics, and make clear their inclusion was a joke. Because nothing is funnier than old white people making fun of rap.


And in a way, that’s sort of telling, because while the times have never been better for the production of art, the only appearance of art in one of the many modern, vital modes being produced today was brought in as a sneering joke. The art that was sincerely held up as having enduring value– even the opening song– was mostly drawn from fields that are on life support, propped up almost exclusively by the elite academic consensus that these are Important.


And in a way, that’s the biggest problem I have with this whole genre of speeches in defense of “the humanities” and academic disciplines in general: they are fundamentally elitist. These speeches aren’t for the students who are ostensibly the purpose of the institution, they’re to flatter the vanity of the faculty and wealthy alumni, and pat them on the back for their essential role in deciding what has value. Which is why the examples cited are always these ancient pressed-under-glass things. Everyone will agree that Aristotle and Eliot are Important, but the really active topics in “the humanities” are multicultural, and deal with critical theory and area studies and identity politics and intersectionality. But those don’t get talked about, because those topics upset people.


Even the obligatory pseudo-economic case is fundamentally kind of elite. The speech included the requisite shout-outs to “critical thinking” and the contractually mandated list of famous people with degrees in a “humanities” discipline. But that’s hugely problematic in a lot of ways, starting with the fact that it’s an argument based on “black swans”– telling students to major in philosophy because it worked for George Soros isn’t all that much different from telling people to buy lottery tickets because some lady in Arkansas hit the PowerBall jackpot.


More than that, though, the whole argument founded on the development of “critical thinking skills” is ultimately a sort of negative argument. It’s a familiar one in physics, because we’re one of the less obviously applied undergrad science majors, and I’ve used versions of it myself in talking to parents who ask what their kids might do after graduation. “You learn to think broadly about a wide range of problems, so you can go off and work in lots of other fields,” we say, but what we really mean is “Go ahead and major in our subject because you enjoy it; it won’t screw up your chances of getting a good job any more than any other major.” And that holds true for the argument applied to “the humanities.”


And, you know, that’s an easy case to make when you’re speaking at an elite private college like Union, because it’s probably true that the precise choice of major doesn’t make a great deal of difference for our students. We don’t quite have the cachet of Harvard or Williams, but we’re at the low end of the upper tier of elite colleges, and the name on the diploma will open enough doors in enough fields that our students will be able to get jobs, albeit not without some effort.


But move down the academic ladder a bit, and I’m not sure that argument works quite as well. A “humanities” degree from Union will carry a good deal more weight than a “humanities” degree from Directional State University. Those students are probably right to give more weight to immediately marketable and relevant credentials; as, for that matter, are many Union students who come from underprivileged backgrounds. Particularly in what remains a sort of dismal economic climate.


So, you know, a lot of stuff that bugged me packed into one short speech. I’m still not sure what I really want to see as a defense of the value of “the humanities,” but this very definitely was not it.

Another breathtaking view of Comet Lovejoy

Comet Lovejoy on December 27, 2015 from the Fermi Dark Energy Camera

Fermilab’s Dark Energy Camera took a break from studying one of the greatest mysteries in modern cosmology – dark energy – to capture this stunning view of Comet Lovejoy – an extremely photogenic comet – on December 27, 2014. At the time this image was taken, the comet was passing about 51 million miles from Earth – a short distance for the Dark Energy Camera, which is sensitive to light up to 8 billion light-years away.


The camera was in the midst of scanning the southern sky for the Dark Energy Survey, which is designed to help uncover the nature of dark energy – a mysterious gravitational force opposite to the attractive gravity – which is causing the observed expansion of the universe to speed up.


The Fermilab Dark Energy Camera is a 570-megapixel camera, said by Fermilab to be the world’s most powerful digital camera. The camera is mounted on the Blanco 4-meter telescope at Cerro Tololo Inter-American Observatory, high in the Chilean Andes.


This camera captured the image above of Comet Lovejoy, which was visible in late 2014 and early 2015. Each of the rectangular shapes above represents one of the 62 individual fields of the camera.

At the time this image was taken, the comet was passing about 51 million miles from Earth – a short distance for the Dark Energy Camera, which is sensitive to light up to 8 billion light-years away.


The camera was in the midst of scanning the southern sky for the Dark Energy Survey, which is designed to help uncover the nature of dark energy – a mysterious gravitational force opposite to the attractive gravity – which is causing the observed expansion of the universe to speed up.


The Fermilab Dark Energy Camera is a 570-megapixel camera, said by Fermilab to be the world’s most powerful digital camera. The camera is mounted on the Blanco 4-meter telescope at Cerro Tololo Inter-American Observatory, high in the Chilean Andes.


This camera captured the image above of Comet Lovejoy, which was visible in late 2014 and early 2015. Each of the rectangular shapes above represents one of the 62 individual fields of the camera.

Are a star’s brightness and luminosity the same thing?


This Renaissance woodcut is called Empedocles Breaks through the Crystal Spheres.

This Renaissance woodcut is called Empedocles Breaks through the Crystal Spheres.



The ancient astronomers believed the stars were attached to a gigantic crystal sphere surrounding Earth. In that scenario, all stars were located at the same distance from Earth, and so, to the ancients, the brightness or dimness of stars depended only on the stars themselves.


In our cosmology, the stars we see with the eye alone on a dark night are located at very different distances from us, from several light-years to over 1,000 light-years. Telescopes show the light of stars millions or billions of light-years away.


Today, when we talk about a star’s brightness, we might mean one of two things: its intrinsic brightness or its apparent brightness. When astronomers speak of the luminosity of a star, they’re speaking of a star’s intrinsic brightness, how bright it really is. A star’s apparent magnitude – its brightness as it appears from Earth – is something different and depends on how far away we are from that star.

Sun

Astronomers often list the luminosity of stars in terms of solar luminosity. The sun has a radius of about 696,000 kilometers, and a surface temperature of about 5800 Kelvin, or 5800 degrees above absolute zero. Freezing point of water = 273 Kelvin = Oo Celsius



For instance, nearly every star that you see with the unaided eye is larger and more luminous than our sun. The vast majority of stars that we see at night with the eye alone are millions – even hundreds of millions – of times farther away than the sun. Regardless, these distant suns can be seen from Earth because they are hundreds or thousands of times more luminous than our local star.


That’s not to say that our sun is a lightweight among stars. In fact, the sun is thought to be more luminous than 85% of the stars in our Milky Way galaxy. Yet most of these less luminous stars are too small and faint to see without an optical aid.


A star’s luminosity depends on two things:


1. Radius measure

2. Surface temperature


Radius measure


Let’s presume a star has the same surface temperature as the sun, but sports a larger radius. In that scenario, the star with the larger radius claims the greater luminosity. In the example below, we’ll say the star’s radius is 4 solar (4 times the sun’s radius) but has the same surface temperature as our sun.


We can calculate the star’s luminosity – relative to the sun’s – with the following equation, whereby L = luminosity and R = radius:


L = R2

L = 42 = 4 x 4 = 16 times the sun’s luminosity


Contrasting size of the star VY CMa with sun

Although the star VY Canis Majoris in the constellation Canis Major has a much cooler surface temperature than our sun, this star’s sheer size makes it a super-luminous star. Its radius is thought to be around 1400 times than of our sun, and its luminosity 270,000 greater than our sun.



Surface temperature


Also, if a star has the same radius as the sun but a higher surface temperature, the hotter star exceeds the sun in luminosity. The sun’s surface temperature is somewhere around 5800 Kelvin (9980o Fahrenheit). That’s 5800 degrees above absolute zero, the coldest temperature possible anywhere in the universe. Let’s presume a star is the same size as the sun but that its surface temperature is twice as great in degrees Kelvin (5800 x 2 = 11600 Kelvin).


We use the equation below to solve for the star’s luminosity, relative to the sun’s, where L = luminosity and T = surface temperature, and the surface temperature equals 2 solar.


L = T4

L = 24 = 2 x 2 x 2 x 2 = 16 times the sun’s luminosity


Luminosity of Star = R2 x T4


Hertzsprung-Russell Diagram

The HR Diagram categorizes stars by surface temperature and luminosity. Hot blue stars (>30,000 Kelvin) at left and cool red stars (<3,000 Kelvin) at right. The most luminous stars (1,000,000 solar) are at top and the least luminous stars (1/10,000 solar) at bottom.



The luminosity of any star is the product of the radius squared times the surface temperature raised to the fourth power. Given a star whose radius is 3 solar and a surface temperature that’s 2 solar, we can figure that star’s luminosity with the equation below, whereby L = luminosity, R = radius and T = surface temperature:


L = R2 x T4

L = (3 x 3) x (2 x 2 x 2 x 2)

L = 9 x 16 = 144 times the sun’s luminosity


Color and surface temperature


Have you ever noticed that stars shine in an array of different colors in a dark country sky? If not, try looking at stars with binoculars sometime. Color is a telltale sign of surface temperature. The hottest stars radiate blue or blue-white, whereas the coolest stars exhibit distinctly ruddy hues. Our yellow-colored sun indicates a moderate surface temperature in between the two extremes. Spica serves as prime example of a hot blue-white star, Altair: moderately-hot white star, Capella: middle-of-the-road yellow star, Arcturus: lukewarm orange star and Betelgeuse: cool red supergiant.


How astronomers learn the masses of double stars


Bottom line: Some stars look bright because they’re near Earth. Others are truly extremely bright members of our Milky Way galaxy. Astronomers call the true, intrinsic brightness of a star its luminosity. The luminosity of any star depends on size and surface temperature. Some extremely large and hot stars blaze away with the luminosity of a million suns!

In Which I Am Outwitted by a Six-Year-Old [Uncertain Principles]

SteelyKid has developed a habit of not answering questions, whether because she’s genuinely zoning out, or just not acknowledging adults, it’s not clear. (She’s going to be a real joy when she’s a teenager, I can tell…) In retaliation, I’ve started giving imaginary answers for her, which generall snaps her out of it, but I’ve been waiting to see what the next step was.


Which was taken last night: in the car on the way to taekwondo sparring class, I asked “What are you guys doing in art class these days?” silence.


“Hey, [SteelyKid]? What are you doing in art these days?”


Silence


“Oh, rattlesnake painting? That sounds pretty cool.”


Silence.


“So, is that painting on rattlesnakes, or with rattlesnakes?”


“Well, it would have to be a dead rattlesnake.” (Finally, a response!)


“I guess. Though I suppose if it were asleep, you could paint on it. You might not want to be around when it woke up, though.”


“Hmmm… OK, here’s what I would do. I would get the snake, and put it to sleep. Then I’d give it to a museum, and they’d keep it until it grew enough to shed its skin. Then they’d give me the skin, and let the snake go.”


“OK.”


“And then I’d paint on the skin– on one side oft he skin. Then I’d take a piece of paper, and press the skin onto the paper, and the paint would go off on the paper and look just like the snake. And then all I’d have to do is draw the head, and color it in.”


“Yeah, I guess that would work. Very clever.”


So, once again, I have lost a battle of wits to a first-grader. Happily, this got her out of the not-answering-questions mode, and she chattered happily about what she’s really doing in art class these days (a project involving a picture of a snowman that sounds a little Calvin and Hobbes), pop music, and various other things. I’m going to have to think up some new absurd activities for future car rides, though, if she’s going to go and raise the bar on me like this.

The Wellness Warrior, Jess Ainscough, has passed away [Respectful Insolence]

Two months ago, I took note of a somewhat cryptic blog post by a young woman named Jess Ainscough. In Australia and much of the world, Ainscough was known as the Wellness Warrior. She was a young woman who developed an epithelioid sarcoma in 2008 and ended up choosing “natural healing” to treat her cancer. Among the “natural healing” modalities touted by the Wellness Warrior included that quackery of quackeries, the Gerson protocol, complete with coffee enemas and everything. She even did videos explaining how to administer coffee enemas and posted them on YouTube, although that video is now private. In fact, most of her videos appear to have disappeared from her YouTube channel, and there is nothing but a notice on her website announcing this:



Banner announcing Jess Ainscough's death


Sadly, yesterday Jess Ainscough passed away. There’s no information on what took her life, but it’s hard not to assume that it was her cancer. Given this development, Ainscough’s words from two months ago make more sense:



When I left you back in June to begin a period of self-care hibernation, my plan was to get my health back in tip top shape and then spend some time creating some awesome new stuff for you. The reality, however, is that I’ve spent the whole time focused on my health. For the last few months, I’ve been pretty much bedridden. Let me fill you in on what’s been going on with me …


This year absolutely brought me to my knees. I’ve been challenged, frightened, and cracked open in ways I never had before. After my mum died at the end of last year, my heart was shattered and it’s still in a million pieces. I had no idea how to function without her, and it turns out my body didn’t either. For the first time in my almost seven year journey with cancer, this year I’ve been really unwell. I’ve lived with cancer since 2008 and for most of those years my condition was totally stable. When my mum became really ill, my cancer started to become aggressive again. After she died, things really started flaring up.


I’ve had scans to detect what’s going on in my body, and I can report that the disease is still contained to my left arm and shoulder, however I do have a big fungating tumour mass in that shoulder that’s causing me dramas. Over 10 months of non-stop bleeding from the armpit has rendered me really weak (and uncomfortable) and as a result I’ve had no choice but to stop absolutely everything and rest. Tallon, my freaking hero, has had to step up and help me with everything from making food and juices, doing all of our housework and laundry to doing my hair.



At the time, I noted that Ainscough’s health had clearly taken a turn for the worse and couldn’t help but wonder whether she was doing even worse than she was letting on. Indeed, at the time, her admission seemed rather amazing, given how jealously she had guarded any hint that she wasn’t doing very well and how careful she was to hide her arm in publicity photos. Of course, this being the age of smartphone cameras, where almost everyone has a camera on herself at nearly all times, she couldn’t always succeed, and photos of her showing how bad her arm was did appear. I also speculated at the time that maybe Ainscough had finally decided to return to “conventional” treatment, possibly even an amputation.


I’ll explain.


I first encountered the Wellness Warrior a year and a half ago when her mother, Sharyn Ainscough, died tragically of breast cancer. Her mother, it turns out, had treated her breast cancer with the same sorts of useless treatments as her daughter treated her sarcoma. Now, I can understand why Jess would choose woo. She was unfortunate enough to develop a cancer that was, paradoxically, both very nasty and very indolent. (After all, she survived seven years with it.) Moreover, because her tumor involved her shoulder, the first line treatment recommended consisted of a very disfiguring amputation that sounded like a forequarter amputation. It’s an amputation that involves removing not just the arm, but removing the entire shoulder joint and the shoulder blade. It would have left her not just without an arm, but without a shoulder as well. It’s a seldom-performed operation these days (indeed, I’ve never done one or even seen one performed in my entire career stretching back to my residency beginning in the late 1980s), and with good reason. Still, sometimes it is necessary. It’s hard not to feel for Ainscough, who, at age 22 was facing such an awful choice.


In my original account I noted that Ainscough actually reported herself to have steeled herself up to undergo the surgery, but apparently her doctors came to her at the last minute with an alternative, which was to do isolated limb perfusion. Basically, this is a technique sometimes used for soft tissue sarcomas of the extremity or multifocal melanoma that can’t be resected without amputation to try to destroy the tumor. As its name implies, isolated limb perfusion involves isolating the limb from the body’s circulation and infusing it with very (and I do mean very) high doses of chemotherapy. That’s what necessitates the isolation of the limb’s circulation; the dose of chemotherapy is so high that if it leaked back into the rest of the circulation the consequences could be disastrous. Isolated limb perfusion can often cause seemingly near miraculous results, and apparently that was the case for Ainscough. Unfortunately, tumors tend to recur, and that’s exactly what happened to Ainscough about a year later, which led to the doctors recommending an amputation of her arm at the shoulder again.


It was at that point that Ainscough rejected that option and was reborn as the Wellness Warrior. Over the years, she became quite the media figure in Australia, enabled by credulous reporting. She had many advantages in this. She was young. She was telegenic. She was very likable and very media-savvy. Over seven years, she built up an impressive empire of “natural healing” modalities, enabled, of course, by credulous reporting. She wrote books. She appeared on television. She sold cookbooks, cooking supplies, and various other implements necessary for a “natural” lifestyle. She promoted, as I said, that cancer quackeries of cancer quackeries, the Gerson therapy. Indeed, she even listed the various supplements she took as part of the Gerson therapy (and in addition to the at least daily coffee enemas), which she described thusly:



Some of you might think the list is a bit extreme, but I assure you that it is totally manageable. It’s nowhere near as much of a pain in the ass to get through as the medicine cabinet full of pills and potions I was taking prior to Gerson. I swear, as soon as we heard that a supplement had anti-cancer properties, I was all over it. I’ve taken everything from sea cucumbers to bovine cartilage. This list is like a trip to the beach in comparison.


The supplements a Gerson patient must take generally varies to suit the individual. But all the medications are designed to support the diet therapy by increasing the energy capacity of the cell and by increasing the rate of detoxification.



She also advocated eating clay to “detoxify” herself:



When we eat clay, the positively charged toxins are attracted by the negatively charged edges of the clay mineral. An exchange reaction occurs where the clay swaps its ions for those of the other substance. Electrically satisfied, it holds the toxin in suspension until the body can eliminate both.



You get the idea. Jess Ainscough was a seemingly unending fountain of woo, making Food Babe-like appeals to the “natural” over the “synthetic” and promoting her version of “wellness.”


So what happened? As I explained before, epithelioid sarcoma is a rare sarcoma, with an incidence on the order of 0.1 to 0.4 per million. It’s primarily a tumor of young adults, and it nearly always appears on the upper extremities, and wide surgical excision is the only known effective treatment. It also tends to be indolent as well. Its ten year survival overall is on the order of 61%, and for patients between 17 and 30 years (i.e., patients like Jessica Ainscough), it’s approximately 72%. Of course, that is with treatment with surgery; without surgery, five year survival is 35% and ten year survival is 33%. Sadly, Jess Ainscough’s survival of seven years with her disease in essence untreated is thus within the expected range of survival time based on her disease that I discussed the last time I discussed her.


I have no idea what finally took her life. It was the cancer, of course. Given her description of frequent bleeding from her tumor mass to the point where she was anemic suggested to me that the tumor was fungating, eating through the skin. At the time, she said her scans indicated that the cancer hadn’t spread beyond the arm, but that didn’t mean it still couldn’t kill her. I’d suspect a combination of unrelenting chronic blood loss and perhaps necrotic tumor becoming infected and leading to sepsis. If such sepsis were not recognized and treated promptly it could certainly have killed her in her weakened state. But this is just speculation, an educated guess. I have no idea what the immediate cause of Jess Ainscough’s death was. Whatever her immediate cause of death was, though, it was almost certainly the cancer that killed her.


Cancer deaths like this always sadden me. Jess Ainscough had a shot, one shot. She didn’t take it. What saddens me even more is that I can understand why she didn’t take it, as, through a horrible quirk of fate, her one shot involved incredibly disfiguring surgery and the loss of her arm. Still, I wish she had taken it and hadn’t instead decided to become an icon of “natural healing.” (If she had, there’s about a 70% chance she’d still be alive today.) In her role as the Wellness Warrior, and in her promotion of Gerson quackery, Ainscough, with the noblest of motivations in the beginning, did great harm and led cancer patients down the path of quackery and death.


All the more sad. I just wish she could have found something less harmful to do with the years that remained to her after her diagnosis.

I swear, as soon as we heard that a supplement had anti-cancer properties, I was all over it. I’ve taken everything from sea cucumbers to bovine cartilage. This list is like a trip to the beach in comparison.


The supplements a Gerson patient must take generally varies to suit the individual. But all the medications are designed to support the diet therapy by increasing the energy capacity of the cell and by increasing the rate of detoxification.



She also advocated eating clay to “detoxify” herself:



When we eat clay, the positively charged toxins are attracted by the negatively charged edges of the clay mineral. An exchange reaction occurs where the clay swaps its ions for those of the other substance. Electrically satisfied, it holds the toxin in suspension until the body can eliminate both.



You get the idea. Jess Ainscough was a seemingly unending fountain of woo, making Food Babe-like appeals to the “natural” over the “synthetic” and promoting her version of “wellness.”


So what happened? As I explained before, epithelioid sarcoma is a rare sarcoma, with an incidence on the order of 0.1 to 0.4 per million. It’s primarily a tumor of young adults, and it nearly always appears on the upper extremities, and wide surgical excision is the only known effective treatment. It also tends to be indolent as well. Its ten year survival overall is on the order of 61%, and for patients between 17 and 30 years (i.e., patients like Jessica Ainscough), it’s approximately 72%. Of course, that is with treatment with surgery; without surgery, five year survival is 35% and ten year survival is 33%. Sadly, Jess Ainscough’s survival of seven years with her disease in essence untreated is thus within the expected range of survival time based on her disease that I discussed the last time I discussed her.


I have no idea what finally took her life. It was the cancer, of course. Given her description of frequent bleeding from her tumor mass to the point where she was anemic suggested to me that the tumor was fungating, eating through the skin. At the time, she said her scans indicated that the cancer hadn’t spread beyond the arm, but that didn’t mean it still couldn’t kill her. I’d suspect a combination of unrelenting chronic blood loss and perhaps necrotic tumor becoming infected and leading to sepsis. If such sepsis were not recognized and treated promptly it could certainly have killed her in her weakened state. But this is just speculation, an educated guess. I have no idea what the immediate cause of Jess Ainscough’s death was. Whatever her immediate cause of death was, though, it was almost certainly the cancer that killed her.


Cancer deaths like this always sadden me. Jess Ainscough had a shot, one shot. She didn’t take it. What saddens me even more is that I can understand why she didn’t take it, as, through a horrible quirk of fate, her one shot involved incredibly disfiguring surgery and the loss of her arm. Still, I wish she had taken it and hadn’t instead decided to become an icon of “natural healing.” (If she had, there’s about a 70% chance she’d still be alive today.) In her role as the Wellness Warrior, and in her promotion of Gerson quackery, Ainscough, with the noblest of motivations in the beginning, did great harm and led cancer patients down the path of quackery and death.


All the more sad. I just wish she could have found something less harmful to do with the years that remained to her after her diagnosis.

Moon inside Winter Circle on February 27


Tonight’s waxing gibbous moon – February 27, 2015 – resides in or near a large asterism that we in the Northern Hemisphere often call the Winter Circle. It’s an incredibly large star configuration made of brilliant winter stars. From North America on this night, the moon is inside the Circle. From anywhere in the Northern Hemisphere, look for the Winter Circle to fill up much of the eastern half of sky at nightfall. By mid-evening, the Winter Circle will swing to your southern sky, and then it will drift into the western sky around midnight. If you’re in the Southern Hemisphere … although it’s not winter for you, these same stars appear near the moon.


Now look beyond the moon and Winter Circle. At early evening, there are two starlike objects shining more brilliantly than any of the Winter Circle stars. To the west, shortly after sunset, you’ll find the planet Venus. To the east of the Circle, throughout the night, you’ll find the planet Jupiter. At present, Jupiter shines in front of the rather faint constellation Cancer the Crab. Sometimes called the year star, Jupiter stays in front of a constellation of the Zodiac for roughly a year. Next year at this time, you’ll still see Jupiter in front of the constellation Leo the lion.


The Winter Circle – sometimes called the Winter Hexagon – is not one of the 88 recognized constellations. Rather, it’s an asterism – a pattern of stars that’s fairly easy to recognize. Our sky chart cannot adequately convey the Winter Circle’s humongous size! It dwarfs the constellation Orion the Hunter, which is a rather large constellation, occupying the southwestern part of the Winter Circle pattern.

Here’s how to locate the Winter Circle from mid-northern latitudes. At nightfall and early evening, look high overhead for the bright star Capella. This star marks the top (or more properly, the northern terminus) of the Winter Circle.


As Capella shines way overhead, the constellation Orion the Hunter is prowling in the southern sky. Draw a line downward through Orion’s Belt to find Sirius, the brightest star in the night sky. This star marks the bottom (the southern tip) of the Winter Circle.


Click on this sky chart if you want to connect the Winter Circle stars.


By the way, tonight’s waxing gibbous moon shows you where the sun resides in front of the backdrop stars in late June or early July. So enjoy the Winter Circle. And contemplate the sun being in this part of the sky when summer returns to the Northern Hemisphere!


Bottom line: On the evening of February 27, 2015, the waxing gibbous moon shines inside of the huge pattern of stars known as the Winter Circle. Be sure to notice the variety in the colors of these stars!

Fry On the Problem Of Evil, Part Two [EvolutionBlog]

There’s lots of good blog fodder out there, but I don’t want to let too much time go by before finishing my discussion of Stephen Fry’s presentation of the Problem of Evil. See Part One for the full context.


Of all the responses I’ve seen to Fry’s interview, there was one that was so bizarre and demented that we just have to take a look at it. And it came from an unexpected source–Larry Moran:



This video is making the rounds and a lot of atheists are wetting their pants over Stephen Fry’s response to the question of what he would would say to “he, she, or it” if he encountered god when he dies.


My questions would be “Who are you? Which groups of humans (if any) got it right when making up a religion? Tell me about yourself and why you didn’t reveal yourself to me.”


That’s not what Stephen Fry would do. He makes the assumption that he knows the mind of god and attacks the god for not being nice to humans. In other words, he accepts the problem of evil and assumes that the god he is facing gives a damn about some obscure species on a minor planet in one of billions of galaxies. Later on Stephen Fry concedes that he could be talking to the Greek gods or some other gods but by then it’s too late.



What’s gotten into Larry? Where do we even begin to unpack all the crazy in those paragraphs?


Fry’s question is premised on not understanding the mind of God. One suspects that if he knew God’s mind, he would also understand why God allows evil.


Fry didn’t actually protest God not being nice to humans. He objected to afflicting children with dread diseases. Why do you need to understand the mind of God to attack Him for that? If it turns out that God just doesn’t care about human suffering, well, then there’s your answer. But that doesn’t make it a poor question.


I have no idea what it means to “accept” the problem of evil. The point of Fry’s question was simply that evil and suffering are facts of life, and we can reasonably wonder why an agent with the power to stop it nonetheless chooses not to. As for why we might think that God gives a damn about us, one possible reason is that He created us in the first place. Are we to assume He did that out of malice?


Fry “concedes” that he could be talking to the Greek gods? What interview was Larry watching? Fry initially took it for granted that his interviewer was referring to the Christian conception of God (the interviewer specifically mentioned the Pearly Gates after all), and then went on to muse about the way other civilizations regarded their Gods. How does this reflect poorly on Fry?


Larry excoriates Fry for not considering the possibility that God does not care about humans. Yet one of his own questions is premised on the idea that God ought to have revealed Himself to him.


But we’re just getting started:



The god he is addressing may or may not have done any of the things in the Bible. If he isn’t that god then he will know that Stephen Fry is attacking a strawman. If he is the god of the Bible then presumably he/she/it had his/her/its reasons for doing apparently evil things and Stephen Fry is about to get educated about the real mind of god. That may turn out badly for Stephen Fry.



It just gets weirder and weirder. Attacking a strawman? What? Fry was asked what he would say to God were he to meet Him. He replied that he would ask God why He allows children to suffer from horrible diseases. How does that constitute attacking a strawman?


Regardless of whether or not we are talking about the God of the Bible, we can assume that if He exists, He has His reasons for allowing evil. I, for one, would like to know what those reasons are. Why does that reflect poorly on me?


If Larry fears it will go badly for Fry when he asks such questions, why does he think it will go any better when Larry asks God petty questions about human religions and the problem of divine hiddenness?


There’s more!



Many of my atheist friends think that Fry’s response is fantastic because he really shocks the interviewer, Gay Byrne. That’s naive. Most intelligent Christians have developed some very good rationalizations concerning the problem of evil. They’ve heard it all before and they know how to respond. One of the classic responses is that cannot they know the mind of god. But Stephen Fry knows the mind of god and this is puzzling because Fry is an atheist.



We can debate how good those rationalizations really are (the very fact that Larry refers to them as rationalizations suggests that he doesn’t think much of them), but what has that to do with the merits of Fry’s questions?


It is, indeed, very common for Christians to respond by saying that we cannot know the mind of God. The prevalence of that response is an admission both that evil and suffering is a serious problem for theists, and also that we have no good answer for it. I would say that only lends urgency to Fry’s question. Given the chance to finally get a definitive answer to this difficult question, I would think that a lot of Christians would ask the same question as Fry.


But Larry wasn’t finished! He then opened a subsequent post with this:



I think it’s ridiculous for atheists to get dragged into the argument from evil. As soon as you start down that path you are conceding that you are willing to debate “sophisticated theology” and not whether god(s) actually exist. The atheist must then be prepared to read a massive amount of literature beginning with St. Augustine of Hippo through Thomas Aquinas and including the most famous “sophisticated” theologians of the 20th century like Alvin Plantinga and Richard Swinburne. If you don’t engage the arguments made by those people, and many others, then you are not being honest.


The “problem of evil” is not simple and atheists do not do themselves any favors by pretending that it is. That’s exactly the criticism we level at theists who don’t even try to understand nonbelievers.



Okay, now he’s just messing with me. There’s no way a smart guy like Larry could believe anything he’s saying.


Atheists get dragged into the argument from evil? Really? I’m pretty sure we’re usually the ones who bring it up. We do that because it’s a good argument.


Larry notes that there is a massive literature on the problem of evil. Indeed there is! Does Larry think that’s evidence of the argument’s weakness? The reason theists have to write so voluminously about it, and the reason that theology and philosophy of religion journals to this day routinely publish new papers trying to defuse it, is that the argument is very strong.


Some of us have gone through that literature. Speaking for myself, it is precisely because I have spent so much time considering the panoply of responses on offer that I am so confident that there is no plausible refutation of the argument to be found. But why is it dishonest to raise the argument without having done that much homework? Am I not allowed to accept evolution until I have read and considered every argument that creationists have ever offered?


You don’t have to think the problem of evil is simple to think it’s a compelling argument against theism.


Larry sometimes lets his desire to be contrarian get the best of his good sense. Hopefully he will return to his senses soon.

Please Don’t Paint Our Planet Pink! [Greg Laden's Blog]

Please Don’t Paint Our Planet Pink!: A Story for Children and their Adults ” is a new children’s book by Gregg Kleiner about global warming. The idea is simple. Imagine if you could see CO2? In the book, it is imagined to be pink. The imagining takes the form of a quirky father, one imagines him to be an inventor of some sort, coming up with the idea of making goggles that would allow you to see CO2 as a pink gas. This is all described by the man’s patient but clearly all suffering son, who eventually dons the prototype goggles and sees for himself.


I read this to Huxley, age 5, and he loved it. He kept asking questions, and saying things like, “Is that true? Really?” I knew he would enjoy the book for its witty chatter and excellent illustrations, but frankly I did not expect him to be enthralled. He is fairly laid back when it comes to matters of science, nature, and for that matter, mathematics. He tends to absorb, then, later makes up song about it or comes up with difficult questions. His reaction was unique.


Bill McKibben’s reaction was pretty strong too. He is quoted as saying, “I’ve often wondered what would happen if CO2 were visible. Now I know!” … except he already knew. There would be pink everywhere. At the density of about 400ppm. More than the 350 value that gives his organization its name!


I had only one small problem with the book, and that is the description of what fossil fuels are. The majority of oil probably formed in aquatic, mainly marine, environments as the detritus of mostly small organisms and invertebrates, not dinosaurs and old trees like the book says. Coal is probably most plant matter, but boggy plants and detritus formed in low spots. And so on. Had I edited the book, I would have asked for a sentence or two to broaden the concept of where fossil fuels come from, and maybe a sentence or two to underscore the fact that the fossil fuels we use today were deposited in fits and starts of many tens of millions of years. The process of painting our planet pink over just several decades has released a huge percentage of that Carbon, mainly as CO2. It is like taking five years to fill up a glass of milk then spilling half of it on the sofa in one second. (A proper analogy for the targeted reading age for this great book.)


People often ask me for a recommendation on a book about climate change for kids. This book is great for that purpose. It fits a wide range of ages, but primarily little kids and elementary school. This is not an explainer on global warming, but rather, a great story that gives a sense of the importance of climate change without totally freaking out the audience. The illustrations by Laurel Thomson are excellent.


Of you want to do something about climate change, buy a few copies and give them to your local school’s library (they probably call it a media center) or your local preschool. And your kid, of course. Or to your annoying climate denying cousin’s kids. That would be good.

Oklahoma’s Jim Inhofe throws a snowball in the Senate to throw cold water on global warming


How did Oklahoma Sen. Jim Inhofe become so wise in the ways of science?


He produced a snowball on the floor of the Senate on Thursday. That’s it. The debate over global warming and climate change is done. Stick in a fork in it.


Yes, sir. The author of “The Greatest Hoax: How the Global Warming Conspiracy Threatens You Future” has discovered frozen water. Outside!


The Hill reports on this eureka moment:


“In case we have forgotten, because we keep hearing that 2014 has been the warmest year on record, I ask the chair, do you know what this is,” Inhofe said to Sen. Bill Cassidy (R-La.), who was presiding over the Senate’s debate, as he removed the snowball from a plastic bag.


“It’s a snowball. And it’s just from outside here. So it’s very, very cold out. Very unseasonable.”


He also said:


“We hear the perpetual headline that 2014 has been the warmest year on record,” he said, referring to a report last month from the National Oceanic and Atmospheric Administration and the National Aeronautics and Space Administration.

Cold in February, who would have guessed?


He could have, of course, come to the Cascades in Washington, which often has the heaviest snowfall in the lower 48. He’d have a hard time making much of a snowball this winter. But he might be pleased to see all the daffodils and cherry blossoms out in Seattle — in February.

How did Oklahoma Sen. Jim Inhofe become so wise in the ways of science?


He produced a snowball on the floor of the Senate on Thursday. That’s it. The debate over global warming and climate change is done. Stick in a fork in it.


Yes, sir. The author of “The Greatest Hoax: How the Global Warming Conspiracy Threatens You Future” has discovered frozen water. Outside!


The Hill reports on this eureka moment:


“In case we have forgotten, because we keep hearing that 2014 has been the warmest year on record, I ask the chair, do you know what this is,” Inhofe said to Sen. Bill Cassidy (R-La.), who was presiding over the Senate’s debate, as he removed the snowball from a plastic bag.


“It’s a snowball. And it’s just from outside here. So it’s very, very cold out. Very unseasonable.”


He also said:


“We hear the perpetual headline that 2014 has been the warmest year on record,” he said, referring to a report last month from the National Oceanic and Atmospheric Administration and the National Aeronautics and Space Administration.


“But now the script has flipped,” he said .

How do Phobos and Deimos look from Mars?

What do the two Martian moons – Phobos and Deimos – look like from the surface of Mars? First of all, they don’t look at all like Earth’s moon does from Earth!


The Martian moons are tiny. The larger moon, Phobos, is only about about 14 miles (23 km) across. And Deimos is about half that size. Plus, these little moons orbit Mars more closely than our moon orbits Earth. But, of course, because they’re so tiny, they appear smaller than our moon does from the surface of their home world.


In fact, Deimos, the more distant moon, looks like a star in Mars’ sky. But it’s twice as bright as any starlike object seen in Earth’s sky. Deimos orbits at nearly the same speed Mars rotates, so it needs three Martian days to crawl from one side of Mars’ sky to the other. And, by the way, a day on Mars is about the same length as Earth’s day.


On the other hand, Phobos – the larger and closer of the two moons – zooms around Mars two and a half times every Martian day. Because it out-races Mars’ rotation, Phobos rises in the west and sets in the east. Phobos appears about a third as large in the Martian sky as our moon does in Earth’s sky. What’s more, Phobos isn’t round like our moon. It resembles a shining gray-white potato.

Phobos has a nearly circular orbit along Mars’ equator. It orbits Mars so closely, however, that its apparent size changes for viewers on the equator. Near the horizon Phobos appears smaller – as it climbs in the sky, Phobos comes nearer the viewer until it’s directly overhead. Then it appears larger. Photos via NASA

For observers on the Martian equator, Phobos eclipses the sun nearly every day. Image via NASA/JPL



Another odd thing about Phobos – it’s not visible all over Mars. Phobos orbits above Mars’ equator so near the planet that it’s always hidden beneath the horizon in the Martian polar regions. Our moon, by contrast, can be viewed anywhere on Earth.


For observers on the Martian equator, Phobos eclipses the sun nearly every day. Eclipses last only about 30 seconds, so quickly does Phobos race across the sky. Because Phobos covers only a fraction of the sun’s disk, eclipses are never total.


For observers in the north and south mid-latitudes of Mars, Phobos never eclipses the sun – it always moves south of the sun (for northern observers) or north of the sun (for southern observers).


Deimos eclipses the sun much less often – about once a month. Because it’s smaller and farther away than Phobos, it would be barely visible against the sun’s disk.


As seen from Mars, Phobos and Deimos pass through phases, just like Earth’s moon. They pass from new to crescent to gibbous to full to gibbous to crescent to new again. However, Deimos’ phases are not terribly obvious – they are seen only as a slow change in brightness. Phobos’ phases are more apparent. Because Phobos is irregular, however, the phases look strange. For example, crescent Phobos looks squashed and jagged.


The surface material of Phobos and Deimos is rich in dark carbon – they are among the darkest moons in the solar system. They reflect about 5% of the light that strikes them – about half as much as Earth’s moon. To get a sense of how dark that is, keep in mind that our moon is about as reflective as asphalt. Phobos and Deimos, then, are half as reflective as asphalt. From the surface of Mars, however, the two moons still look bright and gray-white against the black night sky.

Bottom line: The larger Martian moon, Phobos, is only about about 14 miles (23 km) across. The smaller one, Deimos, is about half that size. These little moons orbit Mars more closely than our moon orbits Earth, but remember … they’re small. Deimos looks like a bright star in Mars’ sky. Phobos looks like a shining gray-white potato!

New Research Suggests Global Warming Is About To Heat Up [Greg Laden's Blog]

A paper just published in Science Magazine helps explain variation we see in the long term Carbon-pollution caused upward trend Earth’s surface temperatures. The research also, and rather ominously, suggests that a recent slowdown in that trend is likely to reverse direction in the near future, causing the Earth’s surface temperature to rise dramatically.


The graph shown above represents the ongoing warming of the Earth’s surface owing to the increased atmospheric concentration of human generated greenhouse gas pollution, mainly CO2. But, have a look at the following graph of changes in concentration of CO2 in the Earth’s Atmosphere:


global-co2-levels-since-1700


As you can see, the increase in CO2 is very steady, while the changes in Earth’s surface temperature is very squiggly. Why? In particular, the Earth’s surface temperatures seem to undergo a series of rapid increases or decreases, and now and then, seem to squiggle up and down along a slowly ascending plateau, as has been happening recently. Climate science deniers have taken this recent slowing in the increase of temperature as a signal that the link between CO2 concentrations and global surface temperatures is a hoax. But real climate scientists focus instead on actually explaining, rather than making up stories about, this variation.


There are several different factors that may cause the shorter term squiggles that we see superimposed on the longer term warming trend. The sun’s energy varies over decades, and this contributes a small amount to the variation. Aerosols (dust), either from human activities or volcanic activity, can produce a cooling effect, and this effect varies across time. If you look at the graph of temperatures, you’ll see a strong downward trend associated with the vast eruption of Mount Pinatubo in 1991, for example. A third source of variation in the upward march of the Earth’s temperature is not really a source of cooling or heating at all, but rather, a shift in where the heat goes. The graph on the top of this post is of “surface temperature,” which is a combination of land-based thermometers at roughly head-height, located at weather stations around the world, and sea surface temperatures. But well over 90% of the heat added to the Earth’s system by the human-caused greenhouse effect actually ends up in the ocean. A small percentage of variation in how much heat goes into, or comes out of, the ocean can cause a large variation in the “surface temperature.” You can think of the surface temperature measurements as a relatively small tail attached to a rather large dog, where the dog is the ocean and the tail is the land based thermometers and the sea surface. (I’ve developed this analogy here.)


That the behavior of the ocean is important can be understood by noting that while surface temperature increase has slowed in recent years, the temperature in the top couple of kilometers of the world’s oceans has continued to increase apace. You can also look at the relationship between the squiggle of the surface temperature curve and El Niño and La Niña events. The former are periods of time when the Pacific ocean is sending heat out into the atmosphere, and the latter are periods of time when the Pacific is sucking more heat in. The following graphic from Skeptical Science illustrates this nicely.


AllENSOwtrends


“ENSO” refers to the El Niño-La Niña cycling. The top line, in red, represents the change over time in surface temperature just during El Niño periods, while the blue line, along the bottom, represents change over time in surface temperature just using La Niña years. As you can see, many of the ups and downs in the long term surface temperature trend seem to represent ENSO variation.


Now, to the recently published study. The paper is “Atlantic and Pacific multidecadal oscillations and Northern Hemisphere temperatures” by Byron Steinmann, Michael Mann, and Sonya Miller, and is published in tomorrow’s Science. (Yes, I have a time machine.) From the abstract:



The recent slowdown in global warming has brought into question the reliability of climate model projections of future temperature change and has led to a vigorous debate over whether this slowdown is the result of naturally occurring, internal variability or forcing external to Earth’s climate system. To address these issues, we applied a semi-empirical approach that combines climate observations and model simulations to estimate Atlantic- and Pacific-based internal multidecadal variability (termed “AMO” and “PMO,” respectively). Using this method, the AMO and PMO are found to explain a large proportion of internal variability in Northern Hemisphere mean temperatures. Competition between a modest positive peak in the AMO and a substantially negative-trending PMO are seen to produce a slowdown or “false pause” in warming of the past decade.



The research (also reviewed here by Chris Mooney) combines observational data (temperature records and the indices for the AMO and PMO) with sophisticated modeling techniques to parse out the contributions of the Pacific and Atlantic oceans, the big dogs of climate change (the Pacific being the much bigger dogs) on surface temperature variability. Essentially, they are trying to determine how much of the squiggling, specially the recent slowing down of temperature increase, is accounted for by “internal variability” as opposed to “forcings.” The former includes the interactions of the surface and the ocean. “Forced” variation is, according to Michael Mann, means “… governed by drivers, be they human (increased greenhouse gas concentrations, sulphate pollutants) or natural (volcanoes, solar output changes). The internal variability is what’s left, it is the purely natural oscillations in the system that have no particular cause, just as weather variations on daily timescales have no particular cause, they just happen.”


One of the findings of this paper, important in climate research but perhaps a bit esoteric, is that the Pacific and Atlantic have mostly independent effects as sources of internal variation. This is not really new, but confirmed by this work. More exactly, treating them as independent provided good results.


But the most important finding is summarized in the following figure, taken from Figure 3 and also reproduced in a writeup by author Mann at Real Climate:


2015-02-12-Sci15FigHuffPost


This shows the AMO, PMO, and the derived (combining the two) NMO values over time. Assume that the highest and lowest values are close to the maximum and minimum that these measures normally reach. Note that there is something of a periodicity in these values. That there would be makes sense. These values represent the way in which the oceans interact with the air, and we know that although there is not perfect periodicity (regularity) in that relationship, historically, every year the ocean is in a phase of removing heat from the atmosphere there is an increased chance of a reversal in that relationship. Now, step back from the contentious issue of climate change for a moment, and imagine that these are values of a blue chip stock you are thinking of investing in. Remember the cardinal rule of getting rich on the stock market: Buy low, sell high! Now, decide if you want to put your hard earned money ito the AMO or the PMO. Clearly, the PMO is at a minimum. Buy now because it is going to go up soon!


Remembering that the PMO was found to be a much bigger source of internal variability than the AMO, and that it is a major player in determining surface temperatures, this can only mean one thing. Things are going to heat up soon. Study author Michael Mann told me, “The PMO appears to be very close to a turning point, based on the historical pattern. So we don’t expect it to continue to plunge downward. We expect a turning point soon.” In his summary of the work in Real Climate, Mann notes that “the most worrying implication of our study [is] that the “false pause” may simply have been a cause for false complacency, when it comes to averting dangerous climate change”


We just had the warmest calendar year on record. Last month, January 2015, was probably the second warmest January on record. Using a 12 month moving average (like in the graph at the top of this post), the last 12 months were the warmest 12 months on record. I hear rumors that February, the month we are in, is relatively warm. We have been seeing signs of the Pacific belching out more heat lately, with El Niño threatening. This could all be a very short term trend, as we expect to happen frequently with the general upward march of surface temperatures owing to greenhouse gas pollution. But this latest paper indicates that it might not be; it could be the beginning of a longer upward trend. Whatever effects of surface warming you might be concerned with — increased storms, drought, more rapid melting of glacial ice, killer heat waves — expect more over the next decade than we have over the last decade. And we had quite a bit of that over the last decade.
