The 2015 Great Backyard Bird Count starts February 13


The Great Backyard Bird Count is a popular citizen science event where people collect valuable information on the health of bird populations all over the world. The 2015 bird count runs from February 13 to February 16. It’s free and easy to participate. You may even be able to turn your bird count into a nice date for Valentine’s Day.


The Cornell Lab of Ornithology and the National Audubon Society started the Great Backyard Bird Count in 1998. Back then, most of the counts were done in the United States and Canada. In 2013, the event went global and many counts were done in countries such as India, Europe, Mexico, and Australia. During the 2014 count, nearly 4,300 bird species were identified, which is estimated to represent about 43% of all the bird species on Earth.

The 2015 count is expected to draw in participants from over 100 different countries.


To join the count, simply spend at least 15 minutes on one or more days of the event counting the types and numbers of birds that you see. Then, submit your data online. More detailed instructions can be found here. Please check out this link before heading out. The FAQs page has a ton of good information.


There is also a photography contest for this year’s event. The rules for the contest can be found at the above link. If you happen to get a nice photo, we would love it if you could share it with us at EarthSky. You can submit photos to EarthSky on Facebook, at Google+ or submit here.


Audubon’s Chief Scientist Gary Langham has advised North American participants to be on the lookout for pine siskins and redpolls this year. Such species may be further south than normal in 2015 because of the poor pine cone seed crops in northern Canada.

Dick Cannings of Bird Studies Canada also commented on the bird count in a press release. He said:



We especially want to encourage people to share their love of birds and bird watching with someone new this year. Take your sweetheart, a child, a neighbor, or a coworker with you while you count birds for the GBBC. Share your passion and you may fledge a brand new bird watcher!



This year’s Great Backyard Bird Count is being organized by the Cornell Lab of Ornithology, the National Audubon Society, Bird Studies Canada, and many other international organizations.


Bottom line: Grab your binoculars—it’s time for the 2015 Great Backyard Bird Count. The event runs from February 13th to 16th. It is free and easy to participate.

Three More Things Every Human Should Know About Light [Uncertain Principles]

Rhett Allain has a list of 5 Things Every Human Should Know About Light, to tie in with the International Year of Light, and it’s a good list with lots of .gifs. Of course, there are some gaps, so let me offer some additional things that everyone ought to know about light:


Light Is a Particle


Rhett and I have a long-running argument about the use of photons in introductory physics; he’s against them for reasons that make no sense to me. To my mind, it is unquestionably true that light has particle-like properties (and here’s a follow-up with some math), and that’s a thing that everybody ought to know.


Quantum Physics Starts with Light


So, Rhett says light is a wave, and I say it’s a particle. which is it? Well, both, really, and that discovery drove the development of quantum physics, as explained in this video:



(Or you can read the approximate text here)


The particle nature of light was introduced by Planck, and refined by Einstein, and the wave nature of matter starts with Bohr’s quantum model of hydrogen, which was needed to explain the light absorbed and emitted by atoms. So, quantum physics is all about light.


And quantum physics is essential to, well, everything. Understanding the quantum physics of light and matter lets us build lasers and semiconductors, which are essential for modern telecommunications and computing. You wouldn’t be able to read this if not for light leading to quantum physics.


(More in this vein: Four Things Everybody should Know About Quantum Physics and Seven Essential Elements of Quantum Physics. And if you prefer video, here’s a TED-Ed animation about Schrödinger’s cat and computers.)


Everything We Know About the Universe Comes From Light


This isn’t just a statement about our heavy reliance on our eyes for getting around the world. Pretty much everything we know about the origin and fate of the universe comes from studying light. We can even use light to detect the existence of stuff that doesn’t emit any light:



See also this Tor.com article I wrote about spectroscopy, jumping off from Gandalf’s assertion that splitting white light to study it departs from the path of wisdom. Far from it– splitting light is behind some of the most amazing discoveries in the history of science.


So, in summary, light is awesome. The more cool things you can know about it, the better.

The Food Babe: “There is just no acceptable level of any chemical to ingest, ever” [Respectful Insolence]


It’s been a while since I’ve taken notice of Vani Hari, a.k.a. The Food Babe, the misguided “food safety” activist who sees chemicals, chemicals, chemicals everywhere and raises fears about them all, especially the ones that she can’t pronounce. The first time I took any significant notice of her was about a year ago, when she was making news for lobbying Subway to remove the “yoga mat chemical” azodicarbonamide from its bread. Of course, as I explained, azodicarbonamide is a safe chemical that disappears during the baking. It’s a maturing agent that makes bread dough rise better and improves the handling properties of doughs, yielding drier, more cohesive doughs that are more pliable, hold together better during kneading, and machine better. Then, she made some astonishing ignorant statements about beer, where she pulled the same routine, to the point where I said labeled her tactics as the “appeal to yuckiness.” Basically, if something sounds yucky to her (such as isinglass, which is derived from the swim bladders of fish and is used in some beers to remove haziness and yeast byproducts. It turns out that The Food Babe makes quite a pretty penny spreading her ignorance and has become sought after to feature in various media appearances, such as magazine covers.


Oh, and she believes in Masuro Emoto’s water woo (in the context of claiming that microwaving is bad for food) and has shown some antivaccine stylings.


For the last few months I’ve been somewhat dreading February, because I knew Hari was poised to release her first book. As I described before, she has more than a fair amount of social media savvy and business acumen, which have allowed her to build the Food Babe brand rapidly and explains (to me at least) why she seemed to come out of nowhere to be on a trajectory to become as influential as Dr. Mehmet Oz. Her book, released this week, is called The Food Babe Way: Break Free from the Hidden Toxins in Your Food and Lose Weight, Look Years Younger, and Get Healthy in Just 21 Days! (Talk about ridiculously long subtitles.) You see, I knew that when it came time for Hari’s book to come out we’d be seeing a lot more of her, and unfortunately that’s what happened. As part of that publicity, Hari was featured in a fairly long feature article in The Atlantic by James Hamblin. The Food Babe: Enemy of Chemicals. It’s a relatively amusing title, to be sure, and there’s a lot that’s good about the article, but there’s a lot that’s downright infuriating as well.


What’s infuriating is that this article is one of the most egregious examples I’ve seen in a long time of “false balance.” In this case, the false balance comes in the form of a “point-counterpoint” style of telling the Food Babe’s story, whereby she makes a claim, which is then refuted or contested by a scientist. You might think: Great! The article is debunking Hari’s nonsense, and, to a reasonable extent it does, but it does so in such a way as to give the illusion that there is actually a scientific controversy about the topics Hari gloms onto. With few exceptions, there isn’t, and for the exceptions she inevitably takes the most fear mongering approach. I suppose I shouldn’t be too surprised. Hamblin has revealed himself to be insufficiently skeptical about dubious medical claims before, specifically about chelation therapy.


On the other hand, I will give Hamblin credit for quoting part of Hari’s book that perfectly encompasses her complete ignorance of chemistry, physiology, and pharmacology:



Her stance on food additives is an absolute one: “There is just no acceptable level of any chemical to ingest, ever.”



So may I assume that Hari doesn’t ingest water? That’s a chemical? What about salt or sugar? Those are chemicals too. What about food? Our food, even part of a perfect raw vegan diet, is chock full of chemicals because organisms, be they plants or animals, are made up of chemicals with structures ranging from very simple to highly complex, such as proteins, nucleic acids, carbohydrates, lipids, and many others.


Yes, I know that when someone like Hari says “chemical,” she isn’t using the scientific definition of the word, which basically describes all matter cooler than plasma. After all, pretty much everything is made up of chemicals. Rather, when someone like Hari says “chemicals,” she means synthetic, man made chemicals. Of course, that’s—if you’ll excuse the term—an artificial distinction. What’s “natural” and what’s not? Is it “unnatural” to modify a natural product and use it? What about mixtures? Yes, Hari’s fear of chemicals is completely over-the-top, and Hamblin notes the criticism that she has received:



Most of the scientists who have spoken on Hari’s work, though, are less than supportive of that sweeping message. Rather, her work has drawn ardent criticism, primarily from a vocal contingent of academic researchers and doctors, who accuse her, in no uncertain terms, of fear-mongering and profiteering. They say that she invokes science when it is convenient, as in the passage above, but demonizes it when it is not—as in her blanket case against any and all genetically modified food. Last month, NPR ran a critique of Hari’s work, quoting several of her outspoken detractors. Science writer Kavin Senapathy, for one, captured the concerns of many in saying that Hari “exploits the scientific ignorance of her followers.” Others, including neurologist Steven Novella, have said that she is to food what Jenny McCarthy is to vaccines.



Yep. The Food Babe is, as I’ve put it, the Jenny McCarthy of food.


Of interest to me, at least, was the part of the profile where Hamblin goes into a bit more detail than I had known before about the Food Babe’s origins:



One cold winter night, when she was in her early 20s, Vani Hari developed some pain in her lower abdomen. She went to a nearby hospital in Charlotte, North Carolina, where she was born and had returned to live after college. In the emergency department, she remembers being told to relax, that her ovaries were “moving,” and she’d be fine. The next morning she went in for a second opinion, and she was diagnosed with appendicitis. Within an hour she was having her appendix laparoscopically excised. Recovering in the hospital that night, she remembers someone took a picture of her, and she ripped it up thinking she looked “so, so bad.” And she definitely felt horrible.


Since graduating from college, Hari had been working as a consultant at Accenture. She kept long, exhausting hours. She recalls being afraid to leave to use the bathroom during meetings because the environment was so intense. She ate decadent catered meals from exorbitant expense accounts. “A bunch of stuff that really doesn’t serve the body,” she recalls. “But I wanted to fit in, I wanted to be a partner. I was ambitious.” But the health issues she’d had as a child—allergies, eczema, asthma—flared up. Over the first year of the job, she gained between 30 and 40 pounds. She felt bad and “didn’t look that great.”


When the appendicitis hit, that was a breaking point. Lying in her hospital bed, Hari said, “I just had this light bulb awakening moment, you know? This isn’t how I want to live.”



Of course, it’s not that uncommon a story among cranks. Mike Adams, for example, cites the origin of his crank activism (although he wouldn’t put it that way, of course) as being due to a deterioration in his health at a young age where he was, if you believe his story, diagnosed with type II diabetes at age 30. Ditto Chris Wark of Chris Beat Cancer, who became an activist after suffering from colon cancer in his 20s, an unusually young age to be stricken with the disease. The “wake up call” of a serious health problem suffered at a young age is a common story among cranks and quacks. After all, young people tend to believe that they are relatively indestructible and can expect good health for several more decades before old age and its attendant problems finally catches up with them. When poor health strikes at such a young age, people can feel cheated.


Of course, it’s great that Hari cleaned up her act, lost a bunch of weight, and saw her health problems go away. However, as all too often happens, she also attributed her health problems to more than just a poor diet and lifestyle. She blamed the evil chemicalz! She blamed processed foods, various food additives, and basically any synthetic chemical. Over time, as I’ve observed, this belief has morphed into a seeming concept that anything with a long chemical name that she can’t pronounce must be bad. Indeed, it’s evolved, as Hamblin notes, to include even things that are perfectly “natural,” such as isinglass derived from fish swim bladders. Hamblin just doesn’t seem to note that the reason isinglass is bad to The Food Babe is nothing more complex than her revulsion that a product of fish swim bladder is used to make some beers. Ditto the product of beaver anal glands and others:



At times, even, Hari’s suspicions lead her to contradict the basic tenet that natural is good. “Readers of my blog know,” she writes in the book, “that the next time you lick vanilla ice cream from a cone, there’s a good chance you’ll be swirling secretions from a beaver’s anal glands around in your mouth.” Indeed. “Called castoreum, this secretion is used as a ‘natural flavor’ not only in vanilla ice cream but also in strawberry oatmeal and raspberry-flavored products.” And, similarly, “If you chew gum, you may also be chewing lanolin, an oily secretion found in sheep’s wool that is used to soften some gums. What nutritional value do you think these disgusting additives have for your body? None! They exist just to get you to buy something fake or that shouldn’t be food, rather than a real alternative.”



Appeal to yuckiness, indeed. And to “chemically-sounding” names. Or whatever else Hari can’t understand or finds gross.


Another thing that drives Hari is an intense competitiveness, which she attributes to her talent as a high school debater. Of course, as I’ve mentioned before, the goal of a debater is not necessarily to come to find out what is accurate and true scientifically. It is to defend your position. It is to attack your opponent’s position. It is to win. It involves marshaling evidence to support a given position, not following the evidence where it leads. Actually, Hari’s love of high school debate and her competitive nature, when coupled with her scientific ignorance, provide a pretty darned good explanation why she is so impervious to correction. So is this:



“There’s disconnect between the language of science and the language of common communication,” Folta said, explaining why, while many people are upset over the GRAS system, it doesn’t bother him. “You can never demonstrate that something is ‘safe.’ Whether it’s water or sugar; there’s no way. Because you can’t test every aspect. All we can say is, of all the things we’ve looked at, there’s no evidence of harm. If you said, can you prove to me beyond a shadow of a doubt that something is safe, I’d say, no way. With vaccines, sure, you can’t account for some extremely rare effect that might be seen in someone with a particular metabolic disorder, but that’s not to say they’re not a tremendous benefit to society as a whole.”



I guess the only good thing about my having encountered Vani Hari is that I became aware of Kevin Folta, an outspoken food scientist. He’s an impressive guy, although I must disagree with him when he says, “I don’t want to throw her under the bus; I want her to get on the bus.” The reason is that I don’t think Hari is educable. I suppose that there’s some slim chance that I’m wrong about this, but I doubt it.


Note: GRAS stands for “generally recognized as safe,” a designation used by the FDA to describe substances that have been in long use and are, well, generally recognized as safe. There might be an issue, as noted by Hamblin, that more substances have gained the GRAS designation than rate it, but the Food Babe goes far beyond science-based calls for reform of the GRAS designation every time she goes off the deep end with respect to science. For instance:



“The scientists who argue with me about this minute data, who keep saying ‘The dose makes the poison,’ Hari says, shaking her head. “Why aren’t we more cautious about the ingredients we allow in our food supply? Why are we allowing all these additives? And what’s the cumulative effect of all these additives together? That’s something people are just starting to study.”



And why are we giving so many vaccines so early? It’s “too many too soon.” What are all those chemicals in vaccines? They’re “toxins.” Truly, Vani Hari is the Jenny McCarthy of food.


And like Jenny McCarthy, Hari thrives on the opposition her crusade provokes. She thrives on victimhood. It’s how she rallies her troops. It’s what she did a a couple of months ago in response to the NPR article mentioned above. She spent a lot more verbiage claiming that her critics were all in the pay of pharmaceutical companies and agribusiness than she did actually trying to refute anything. Yes, there were some despicably misogynic comments directed at her, as, unfortunately, many women suffer online. (It always pisses me off to see such behavior from anyone on “our side.”) Unfortunately she wielded them like a shield and tried to use them to paint “our side” as nothing more than a bunch of misogynistic trolls, in the pay of Monsanto, of course.


I have little doubt that Hari started out sincere and probably still is, mostly. Hers is a classic American “rags-to-riches” story, at least in the Internet era. Not so long ago, no one, including myself, had ever heard of Vani Hari. Now everyone knows who The Food Babe is. Unfortunately, the Internet and today’s media often don’t distinguish that much between science and pseudoscience when it comes to fame and influence.

Ditto the product of beaver anal glands and others:



At times, even, Hari’s suspicions lead her to contradict the basic tenet that natural is good. “Readers of my blog know,” she writes in the book, “that the next time you lick vanilla ice cream from a cone, there’s a good chance you’ll be swirling secretions from a beaver’s anal glands around in your mouth.” Indeed. “Called castoreum, this secretion is used as a ‘natural flavor’ not only in vanilla ice cream but also in strawberry oatmeal and raspberry-flavored products.” And, similarly, “If you chew gum, you may also be chewing lanolin, an oily secretion found in sheep’s wool that is used to soften some gums. What nutritional value do you think these disgusting additives have for your body? None! They exist just to get you to buy something fake or that shouldn’t be food, rather than a real alternative.”



Appeal to yuckiness, indeed. And to “chemically-sounding” names. Or whatever else Hari can’t understand or finds gross.


Another thing that drives Hari is an intense competitiveness, which she attributes to her talent as a high school debater. Of course, as I’ve mentioned before, the goal of a debater is not necessarily to come to find out what is accurate and true scientifically. It is to defend your position. It is to attack your opponent’s position. It is to win. It involves marshaling evidence to support a given position, not following the evidence where it leads. Actually, Hari’s love of high school debate and her competitive nature, when coupled with her scientific ignorance, provide a pretty darned good explanation why she is so impervious to correction. So is this:



“There’s disconnect between the language of science and the language of common communication,” Folta said, explaining why, while many people are upset over the GRAS system, it doesn’t bother him. “You can never demonstrate that something is ‘safe.’ Whether it’s water or sugar; there’s no way. Because you can’t test every aspect. All we can say is, of all the things we’ve looked at, there’s no evidence of harm. If you said, can you prove to me beyond a shadow of a doubt that something is safe, I’d say, no way. With vaccines, sure, you can’t account for some extremely rare effect that might be seen in someone with a particular metabolic disorder, but that’s not to say they’re not a tremendous benefit to society as a whole.”



I guess the only good thing about my having encountered Vani Hari is that I became aware of Kevin Folta, an outspoken food scientist. He’s an impressive guy, although I must disagree with him when he says, “I don’t want to throw her under the bus; I want her to get on the bus.” The reason is that I don’t think Hari is educable. I suppose that there’s some slim chance that I’m wrong about this, but I doubt it.


Note: GRAS stands for “generally recognized as safe,” a designation used by the FDA to describe substances that have been in long use and are, well, generally recognized as safe. There might be an issue, as noted by Hamblin, that more substances have gained the GRAS designation than rate it, but the Food Babe goes far beyond science-based calls for reform of the GRAS designation every time she goes off the deep end with respect to science. For instance:



“The scientists who argue with me about this minute data, who keep saying ‘The dose makes the poison,’ Hari says, shaking her head. “Why aren’t we more cautious about the ingredients we allow in our food supply? Why are we allowing all these additives? And what’s the cumulative effect of all these additives together? That’s something people are just starting to study.”



And why are we giving so many vaccines so early? It’s “too many too soon.” What are all those chemicals in vaccines? They’re “toxins.” Truly, Vani Hari is the Jenny McCarthy of food.


And like Jenny McCarthy, Hari thrives on the opposition her crusade provokes. She thrives on victimhood. It’s how she rallies her troops. It’s what she did a a couple of months ago in response to the NPR article mentioned above. She spent a lot more verbiage claiming that her critics were all in the pay of pharmaceutical companies and agribusiness than she did actually trying to refute anything. Yes, there were some despicably misogynic comments directed at her, as, unfortunately, many women suffer online. (It always pisses me off to see such behavior from anyone on “our side.”) Unfortunately she wielded them like a shield and tried to use them to paint “our side” as nothing more than a bunch of misogynistic trolls, in the pay of Monsanto, of course.


I have little doubt that Hari started out sincere and probably still is, mostly. Hers is a classic American “rags-to-riches” story, at least in the Internet era. Not so long ago, no one, including myself, had ever heard of Vani Hari. Now everyone knows who The Food Babe is. Unfortunately, the Internet and today’s media often don’t distinguish that much between science and pseudoscience when it comes to fame and influence.

Moon, Saturn and star Antares before dawn February 13


In the sky before dawn on February 13, 2015, you can see the moon, the planet Saturn and the star Antares, brightest star in Scorpius the Scorpion, as they appear from North America. As seen from the world’s Eastern Hemisphere – Europe, Africa, Asia, Australia and New Zealand – the moon will appear even closer to Saturn on the morning of February 13 than it does in our part of the world. Set an alarm! It’ll be a lovely sight.


Here’s a helpful sky trick. The illuminated side of a waning moon always points in the direction that the moon travels: eastward in front of the backdrop stars. So expect the moon to descend toward the sunrise point on the horizon in the days ahead.


In the chart below, we cover a larger area of sky, showing the sky scene for about one hour before sunrise on February 15, 16 and 17 at mid-northern North America latitudes. Sky charts often show the ecliptic – the Earth’s orbital plane projected onto the constellations of the Zodiac – because the moon and planets are always found in this region of sky.

If you’ve never seen Mercury – the sun’s innermost planet and most elusive of the bright planets – be sure to watch over the coming days. Will you see it? Well, it’ll be tough to spot Mercury with the unaided eye at northerly latitudes, but it can likely be seen with the eye alone in the northern tropics or the Southern Hemisphere.


Whether you live in the Northern Hemisphere or the Southern Hemisphere, watch as the waning moon slides down the ecliptic – or pathway of the sun, moon and planets – in the coming mornings. It’ll be getting closer and closer to Mercury on our sky’s dome. Note that the bow of the waning crescent moon points in the general of direction of Mercury. Mercury will be in between that lighted crescent and the sunrise point. With binoculars, or even with the eye, you might catch this world near the horizon if you’re blessed with an unobstructed horizon and clear sky.

Bottom line: On the morning of February 13, 2015, use the moon to locate the planet Saturn and star Antares as our neighboring world continually goes eastward in front of the backdrop stars of the Zodiac. If you’re real lucky, you might even catch Mercury by the horizon as darkness gives way to dawn.

DSCOVR launch a success!

NOAA’s DSCOVR satellite atop a SpaceX Falcon 9 rocket lifted off at 6:03 pm ET on Wednesday, February 11, 2015, from NASA’s Kennedy Space Center. Previously scheduled launches on Sunday and Monday were canceled due to unfavorable weather conditions.


The launch was expected to be SpaceX’s second attempt to test reusable rockets, after the previous attempt, less than a month ago, crashed and burst into flame, but today poor weather conditions canceled the plan. The plan had been for the first stage of the Falcon 9 rocket to come back down to earth and land on a barge near the Florida coast, but the rocket will instead attempt a “soft landing” into the water, where it’s unlikely to be recovered.

DSCOVR mission is a fascinating one. The spacecraft’s primary mission is to monitor space weather – effects from the material and energy from the sun that can impact our satellites and technological infrastructure on Earth.


DSCOVR’s destination is one of the sun-Earth Lagrangian points – Lagrange 1 – a point in the Earth-sun system some 932,000 miles (1.5 million km) from Earth, where the the gravitational forces between the sun and Earth create a relatively stable place for a space vehicle to orbit. A spacecraft can orbit the Lagrange 1 point just as it can orbit a planet. Lagrange 1 lies far beyond Earth’s magnetic environment, making it a perfect place to measure the constant stream of particles from the sun, known as the solar wind, as they pass by.


From its orbit around Lagrange 1, DSCOVR will provide critical data necessary for NOAA space weather forecasters to issue timely and accurate warnings of solar storms, which have the potential to disrupt major public infrastructure systems such as power grids, telecommunications, aviation and GPS.


In addition to the space weather instruments, DSCOVR will carry two NASA Earth-observing instruments that gather ozone, aerosol, cloud, and vegetation measurements (EPIC) and changes in the Earth’s radiation budget (NISTAR).


DSCOVR is a planned two-year mission, but its fuel could last five years, say scientists.
