A novel approach to star trails

Star trail photography has gained popularity in recent years. What are star trails?

The Earth rotates or spins on its axis about every 24 hours, causing an apparent movement of the stars overhead by about one-quarter of a degree per minute. If we leave a camera in a fixed position and point upwards, open the shutter in bulb mode and let the Earth rotate under the stars, we will create an image with star trails. Similarly we could take shorter exposures and superimpose (stack) the images with image processing software.

Most images of star trails taken in the Northern Hemisphere show a pattern similar to the one below taken in Arches National Park, Utah, in spring of 2016.

The location of the North Pole can be clearly seen; the star close to the center is Polaris.

Naturally, we would expect a similar image for the South Pole, and this is indeed the case. There is one important difference: When looking southwards in the Southern Hemisphere, we can also see the Milky Way, best observed from March to about late August. The star trail image below taken at the Siding Spring Observatory in New South Wales, Australia, late April (total of 1250 images @ 30s each, from dusk to dawn) shows circumpolar rings:

The image seems to have lost all the beautiful details of the Southern Milky Way, although when looking towards the center there are clear traces of red, indicating the smear of the Eta Carina nebula in a circumpolar pattern. Can this be improved?

Let’s take a look at a time lapse sequence in one hour intervals. The apparent rotation around the South Pole of the Milky Way from the early evening at 7 pm to the early morning at 5 am is spectacular.

What makes the sky visible from Earth’s Southern Hemisphere so attractive is the fact that the constellation Sagittarius rises in the east (left side) and then reaches the zenith in the early morning hours in late April. This region is heavily populated with nebulae and well known objects, and it is also where the center of our own galaxy is located – the galactic center – home to a massive black hole. Saturn was also clearly visible in this region in April, 2017.

When we take another look at the rotating Milky Way animation we can spot the Large Magellanic Cloud diving below the horizon in the late evening and the Small Magellanic Cloud rising in the early morning hours. In the Northern Hemisphere, Sagittarius is well visible at lower latitudes, but we cannot see location of the South Pole.

We could possibly further improve the sequence with better image processing such as color correction and levels? It looks nice but that’s it, one of many time-lapse clips published widely. But where is the spark?

We need some novelty, so how about superimposing the above sequence into one image? Let’s give it a try:

The result above is surprising: The distinct colorful objects of the Southern Hemisphere sky such as the Eta Carinae Nebula, the Large and Small Magellanic Clouds, as well as the thick bright dust patches of the Sagittarius region, clearly become visible as the Milky Way paints a clock-like pattern across the sky – resembling a large cosmic clock. Curiously, the pattern at the location of the South Pole is artistic, with fractal dimensions.

As we increase the interval between successive images of the sequence from minutes to hours, we can watch the Milky Way paint discrete patterns.

Cassandra Callender’s cancer is progressing, and the quackery isn’t stopping it [Respectful Insolence]

This is the sort of story that I really hate but feel obligated to discuss. I hate these stories because they usually portend the unnecessary death of a cancer patient, often a child with cancer whose parents refuse chemotherapy or who refuses chemotherapy and is unfortunate enough to have a parent who either has alternative medicine proclivities herself, lacks the guts to tell the child that he’s getting treated for his own good and he doesn’t have a choice in the matter, or, in a couple of cases that I’ve discussed, conflates using indigenous people’s medicine instead of chemotherapy as a way of asserting their cultural identity. In the vast majority of these cases, the child has a highly curable lymphoma or leukemia. Not infrequently, the child undergoes one or two rounds of chemotherapy, and the child and/or parent, alarmed at the side effects, decides that the child doesn’t need the rest of the chemotherapy course. This seems to be more likely to happen if the child has a great response to the first round or two of chemotherapy and goes into complete remission. Unfortunately, the chemotherapy regimens for childhood leukemias and lymphomas are long for a reason. Oncologists don’t give up to two and a half years of chemotherapy because they like poisoning children. Decades ago, they learned that if they didn’t give such prolonged courses of chemotherapy, the cancer was likely to return, even if it had gone into remission after only one or two courses of intensive chemotherapy. Unfortunately, that reality has led too many parents who, understandably, can’t stand seeing their children suffering chemotherapy effects to go along with prematurely stopping the chemotherapy.

The names of the children and adolescents with cancer I’ve discussed resonate over the years who have refused chemotherapy still resonate with me even though it’s been a while since I discussed such a case: Abraham Cherrix, Sarah Hershberger, Daniel Hauser, Makayla Sault (who died), and, of course, Cassandra Callender.

Cassandra Callender was a particularly problematic case to me, and I want to update you on what’s happening because readers have written to me. But first a little background for those not familiar with the case. I considered her case problematic because she was 17 years old when she refused chemotherapy. She had developed Hodgkin’s lymphoma, a very treatable malignancy with an estimated expected survival rate of 85%. At the risk of being repetitive, I strongly believe that competent adults have the right to decided their own medical care. They can choose science-based medicine, no treatment at all, or even quackery; I consider it my mission to try to discourage the use of quackery through educating the public. Children are different, however. They depend on their parents and are not considered competent to make such life-or-death decisions. Of course, when children develop the ability to understand the consequences of their decisions is, of course, debatable, as a six year old or eight year old is quite different in his ability to reason and understand consequences than a 13 year old or 16 year old. We as a society have decided that 18 is the age of adulthood for legal purposes. I also realize that society has to pick a number. But what about 17 year olds? They’re pretty damned close to adults. Cassandra Callender was 17 when she was basically locked in a hospital room and forced to undergo chemotherapy. Yes, it was all for her own good, and legally she was not yet an adult, but if you don’t feel at least a little uneasy about her case, even if you ultimately decided it was the right thing to do to make sure she was treated, well, Mister (or Ms.) you’re a better man (or woman) than I.

Not surprisingly, Callender’s case became a cause célèbre among the alternative medicine crowd, as all such cases do—but even more so because of how old she was. Not surprisingly, a few weeks before she was to turn 18, Callender found her way to cancer quack Ty Bollinger, who interviewed her for his “Truth About Cancer” series as an example of “medical kidnapping.” During the interview, which is still in Bollinger’s series, Callender demonstrated magical thinking at ever level, believing that there really is another effective way to eradicate her cancer “naturally” or with homeopathy. At the same time, she hinted at bad news, mentioning a recent PET scan that “didn’t look good.”

Unfortunately, a few months later we learned that she had relapsed in the form of a mass in her lung. Fortunately, this being Hodgkin’s lymphoma, that wasn’t a death sentence. Her disease was far from terminal, but it would likely have required salvage chemotherapy followed by an autologous stem cell transplant. Basically, her bone marrow would be harvested for stem cells, and then she would undergo high dose chemotherapy to wipe out her bone marrow, after which she’d undergo a bone marrow transplant. Her expected survival? Between 40-60%.

So here’s what’s going on. I’ve recently been made aware of Callender’s GoFundMe page, and the news is not good. The page was set up on March 14, 2017, and this is the story:

This page has been set up to help raise money for Cassandra’s 2nd battle against Hodgkin’s lymphoma . In 2014 she was diagnosed and pronounced in remission after 6 months of chemotherapy in 2015. 9 months later in 2016 Cassandra had found out she relapsed with a mass in her left lung and surrounding neck/chest. She spent the whole year using alternative treatments / cannabis oils but unfortunately the cancer became more aggressive. In January of 2017 cassandra discovered that now both of her lungs are full of masses along with her surrounding lungs , chest , surrounding heart and neck . Cassandra now has to go through a very intensive 6-9 months of chemotherapy, again in hopes that things clear up. Her life expectancy doesn’t look well at the moment and it’s going to be quite the battle . She no longer has a normal breathing capacity and struggles with daily life functions that the sickness brings . She is unable to work, is now behind on bills and overall the financial struggle of going through this process yet again is taking a financial toll on her and her family . Any donations would be appreciated at this time . All donations will go directly to Cassandra. After going through this battle once already , Cassandra looks at life as everyday a gift especially when the next day is not promised .

So basically, the woo isn’t working, and Callender’s disease is progressing alarmingly. Cannabis oils didn’t stop the cancer because cannabis does not cure cancer. Sadly, none of this is a surprise; untreated relapsed Hodgkin’s lymphoma is not going to go away on its own, and that’s basically what would have had to have happened for Callender to get better. Interesting, around the same time, the despicable cancer quack Ty Bollinger posted this on his “Truth About Cancer” Facebook page:

Here’s the interesting thing. The Vimeo link to the video above is dead. Similarly, the link to an earlier video from Callender that Ty Bollinger had posted to Facebook is also dead:

So clearly Callender had gone to Tony and Marcy Jimenez’s Hope 4 Cancer Institute in—where else?—Mexico, a mere 30 minutes south of the border near San Diego. In other words, this is a Tijuana quack clinic. And, boy, is it ever! Just take a look at what it offers:

Yes, any place that offers coffee enemas to treat cancer is a quack clinic par excellence, particularly when the practitioners there justify it the way Hope4Cancer does. Besides regurgitating the usual “death begins in the colon” tripe so beloved of those who think that toxins from built up poop in the colon cause cancer, the Jiminezes offer this gem:

Coffee from the coffee enemas (this is not regular coffee that is available in the market!) preferentially absorbs through the venous system in the lower part of the colon going directly to the liver. The coffee stimulates the liver to produce more bile that flushes out the toxins from the organ, This frees up the liver’s capacity to process more toxins instead of being in a constant state of overload. Without this detoxification, the toxins remain concentrated in the bloodstream and upstream in the various tissues and organs, causing overall toxicity in the body.

Only someone with minimal to no understanding of physiology could come up with a ridiculous explanation like this. Even if coffee did stimulate the liver to produce more bile that wouldn’t “free up the liver’s capacity to process more toxins instead of being in a constant state of overload.” That’s not how the liver works.

Perhaps my favorite is this one:

At Hope4Cancer Institute we require that the patients watch an Immuno-Imagery program, a health imaging video and audio series that promotes health from within. This unique self-imaging system combines the scientific discoveries of psychoneuroimmunology (the study of the interaction between the mind and the immune system) with the latest professional guided imagery and deep relaxation techniques of Emmett E. Miller, M.D., a nationally acclaimed physician specializing in Psychophysiological Medicine.

This comprehensive program contains time-lapse motion picture photography through a microscope of actual immune cells. It reveals captivating animation, coupled with an inspiring narration that describes just how the body defends itself. These images guide the patient through a visualization process that helps activate their immune system. The audio provides relaxation and visualization guidance with soothing music and calming sounds of nature. Dr. Miller comments, “IMMUNO-IMAGERY provides a crucial element in any program designed to support the healing process in a most beneficial way, providing clear, vivid images of healthy functioning immune cells doing exactly what you want them to do within your body.”

Great. So the Jimenezes sell the marks a bunch of videos of animations of how the immune system works with a soundtrack of soothing nature sounds as a method of showing patients how to tell their immune system to attack the cancer. Yeah, that’ll work. (That’s sarcasm, people.) I particularly like the woo babble (like Star Trek technobabble but with woo) about psychoneuroimmunology, proving once again that quacks can co-opt any scientific term in the service of selling stuff.

Then there’s this:

At Hope4Cancer Institute we have the technology and know-how to extract, from urine, the proteins that are produced by the cancer cells and develop a vaccine “Autologous Antigen Receptor Specific Oncogenic Target Acquisition” (AARSOTA). This vaccine is administered intramuscularly at specific intervals to promote an antigen-antibody response and provide immunological information to the antibodies. The immunological response enhances specific cancer fighting ability by the body’s defense system.

Tumor markers are measurable biochemicals that are associated with a malignancy. They are either produced by tumor cells (tumor-derived) or by the body in response to tumor cells (tumor-associated). They are typically substances that are released into the circulation and thus measured in the blood. There are a few exceptions to this, such as tissue-bound receptors that must be measured in a biopsy from the solid tumor or proteins that are secreted into the urine.

It all sounds pretty impressive; that is, if you don’t know anything about cancer. What amazed me even more is that the Jimenezes basically admit that what they are doing is complete bullshit:

As tumor cells grow and multiply, some of their substances can increase and leak into the bloodstream or other fluids. Depending upon the tumor marker, it can be measured in blood, urine, stool or tissue. Some widely used tumor markers include: AFP, beta-HCG, CA 15-3, CA 19-9, CA 27.29, CA 125, CEA, and PSA. Some tumor markers are associated with many types of cancer; others, with as few as one. Some tumor markers are always elevated in specific cancers; most are less predictable. However, no tumor marker is specific for cancer and most are found in low levels in healthy persons, or can be associated with non-neoplastic diseases as well as cancer. Also, no tumor marker test is free of false negatives or false positives.

Which basically tells you that trying to make a vaccine out of all these tumor markers isolated from the urine is doomed to failure. In the slideshow that accompanies this woo babble, slide 6 shows a list of cancer vaccines in development by other companies without noting that the antigens being targeted are far more specific to the tumors being treated. The presentation also includes a slide about how whole cell extracts are good sources of cancer antigens, as though this justifies the approach of extracting the urine. In particular, I note that not a single scientific paper or clinical trial is presented to justify the treatment, which is called “Autologous Antigen Receptor Specific Oncogenic Target Acquisition” (AARSOTA).

The case of Cassandra Callender saddens me. There’s no doubt that she got a raw deal, first being diagnosed with cancer and then being on the wrong end of the 85% survival rate for Hodgkin’s lymphoma when she relapsed. However, she still had a decent shot to salvage the situation. It would have been a hard and painful road. The high dose chemotherapy and autologous stem cell rescue still had about a 50-50 chance of failing. But the flip side of that is it also had a 50-59 chance of succeeding. By choosing quackery, unfortunately Cassandra Callender chose death, even as she thought she was choosing life. Her tumor is progressing.

If she thinks that the quacks at Hope4Cancer and Ty Bollinger don’t know that, she should ask them why they’ve’ scrubbed her the two videos about her “journey” at Hope4Cancer from Vimeo. (Certainly I couldn’t find them.) The reason is simple. She is a testimonial they used to sell their quackery, and a patient dying of cancer doesn’t make a good sales tool.

It’s still not too late. At least, I hope it’s not, but every week without effective treatment further diminishes the chances that Callender can be saved. I just hope she takes that chance and seeks real medical treatment instead of quackery as soon as possible.

Also, no tumor marker test is free of false negatives or false positives.

Which basically tells you that trying to make a vaccine out of all these tumor markers isolated from the urine is doomed to failure. In the slideshow that accompanies this woo babble, slide 6 shows a list of cancer vaccines in development by other companies without noting that the antigens being targeted are far more specific to the tumors being treated. The presentation also includes a slide about how whole cell extracts are good sources of cancer antigens, as though this justifies the approach of extracting the urine. In particular, I note that not a single scientific paper or clinical trial is presented to justify the treatment, which is called “Autologous Antigen Receptor Specific Oncogenic Target Acquisition” (AARSOTA).

The case of Cassandra Callender saddens me. There’s no doubt that she got a raw deal, first being diagnosed with cancer and then being on the wrong end of the 85% survival rate for Hodgkin’s lymphoma when she relapsed. However, she still had a decent shot to salvage the situation. It would have been a hard and painful road. The high dose chemotherapy and autologous stem cell rescue still had about a 50-50 chance of failing. But the flip side of that is it also had a 50-59 chance of succeeding. By choosing quackery, unfortunately Cassandra Callender chose death, even as she thought she was choosing life. Her tumor is progressing.

If she thinks that the quacks at Hope4Cancer and Ty Bollinger don’t know that, she should ask them why they’ve’ scrubbed her the two videos about her “journey” at Hope4Cancer from Vimeo. (Certainly I couldn’t find them.) The reason is simple. She is a testimonial they used to sell their quackery, and a patient dying of cancer doesn’t make a good sales tool.

It’s still not too late. At least, I hope it’s not, but every week without effective treatment further diminishes the chances that Callender can be saved. I just hope she takes that chance and seeks real medical treatment instead of quackery as soon as possible.

Circumpolar stars don’t rise or set

Circumpolar stars stay above the horizon all hours of the day, every day of the year. Circumpolar stars neither rise nor set but always remain in the sky. They’re up even in daytime when you can’t see them.

For instance, the stars of the famous Big Dipper asterism are circumpolar at all latitudes north of 41o north latitude, which includes the northern half of the mainland United States and most of Europe.

Big dipper

From the northern U.S., Canada or similar latitudes, the Big Dipper is circumpolar, always above your horizon. Image shows Big Dipper at midnight at various seasons. “Spring up and fall down” for the Dipper’s appearance in our northern sky. It ascends in the northeast on spring evenings and descends in the northwest on fall evenings. Image via burro.astr.cwru.edu

How many circumpolar stars appear in your sky depends on where you are. At the Earth’s North and South Poles, every star is circumpolar. At the Earth’s equator, no star is circumpolar. Places between the equator and poles have some stars that are circumpolar, and some stars that rise and set daily (like the sun).

We in the Northern Hemisphere are lucky to have a moderately-bright star, Polaris, nearly coinciding with the north celestial pole – the point in the sky that’s at zenith (straight overhead) at the Earth’s North Pole.

Draw an imaginary line straight down from Polaris, the North Star, to the horizon, and presto, you have what it takes to draw out the circle of circumpolar stars in your sky.

If you live in the Northern Hemisphere, an imaginary vertical line from the north celestial pole to the horizon serves as a radius measure for the circle of circumpolar stars in your sky. The closer you are to the Earth's North Pole, the closer the north celestial pole is at zenith (straight overhead).

In the Northern Hemisphere, an imaginary vertical line from the north celestial pole to your horizon serves as a radius measure for the circle of circumpolar stars in your sky. The closer you are to the Earth’s North Pole, the closer the north celestial pole is to your zenith (overhead point).

For people in the Northern Hemisphere, Polaris nearly pinpoints the center of the great big circle of circumpolar stars on the sky’s dome; and the imaginary vertical line from Polaris to the horizon depicts the radius measure. (See the above chart, which has this line drawn in for you.) Let your arm serve as a circle compass, enabling you to envision the circle of circumpolar stars with your mind’s-eye. Closer to the equator, the circle of circumpolar stars grows smaller; nearer to the North Pole (or South Pole) the circle of circumpolar stars grows larger.

This technique for locating the circle of circumpolar stars works in the Southern Hemisphere, as well. However, it’s trickier to star-hop to the south celestial pole – the point on the sky’s dome that’s at zenith over the Earth’s South Pole. Practiced stargazers in the Southern Hemisphere rely on the Southern Cross, and key stars, to star-hop to the south celestial pole, as depicted in the illustration below:

The Big Dipper and the W-shaped constellation Cassiopeia circle around Polaris, the North Star, in a period of 23 hours and 56 minutes. The Big Dipper is circumpolar at 41o N. latitude, and all latitudes farther north.

The Big Dipper and the W-shaped constellation Cassiopeia circle around Polaris, the North Star, in a period of 23 hours and 56 minutes. The Big Dipper is circumpolar at 41o N. latitude, and all latitudes farther north.

The Southern Cross is circumpolar anywhere south of 35o south latitude; yet, in the Northern Hemisphere, it’s the W or M-shaped constellation Cassiopeia that’s circumpolar at all places north of 35o north latitude. (Scroll upward to the chart showing Cassiopeia at nightfall for mid-northern latitudes.)

By the way, Cassiopeia lies on the opposite side of Polaris from the Big Dipper. So from mid-northern latitudes, the Big Dipper and Polaris help you to locate Cassiopeia. See the animation at right, whereby all the stars revolve full circle around the celestial pole each day – or more precisely: every 23 hours and 56 minutes.

If Cassiopeia is circumpolar in your sky, then the Southern Cross never climbs above your horizon; and conversely, if the Southern Cross is circumpolar in your sky, then the constellation Cassiopeia never climbs above the horizon.

As seen from the tropics (and subtropics), neither the Southern Cross nor Cassiopeia is circumpolar. From this part of the world, the Southern Cross rises over the southern horizon when Cassiopeia sinks below the northern horizon; and conversely, Cassiopeia rises over the northern horizon when the Southern Cross sinks below the southern horizon.

Bottom line: Circumpolar stars stay above the horizon all hours of the day, every day of the year. Although you can’t see them, they’re up even in daytime.

Saturn moon may have tipped over

NASA recently called Saturn’s moon Enceladus “the storyteller,” because it has a story to tell about events in the early solar system. Image via NASA JPL.

Saturn’s icy, ocean-bearing moon Enceladus may have tipped over in the distant past, according to recent research from NASA’s Cassini mission. Researchers with the mission found evidence that the moon’s spin axis — the line through the north and south poles — has reoriented, possibly due to a collision with a smaller body, such as an asteroid.

Examining the moon’s features, the team showed that Enceladus appears to have tipped away from its original axis by about 55 degrees — more than halfway toward rolling completely onto its side. Radwan Tajeddine, a Cassini imaging team associate at Cornell University, Ithaca, New York, and lead author of the paper, said:

We found a chain of low areas, or basins, that trace a belt across the moon’s surface that we believe are the fossil remnants of an earlier, previous equator and poles.

The area around the icy moon’s current south pole is a geologically active region where long, linear fractures referred to as tiger stripes slice across the surface. Tajeddine and colleagues speculate that an asteroid may have struck the region in the past when it was closer to the equator. Tajeddine said:

The geological activity in this terrain is unlikely to have been initiated by internal processes. We think that, in order to drive such a large reorientation of the moon, it’s possible that an impact was behind the formation of this anomalous terrain.

In 2005, Cassini discovered that jets of water vapor and icy particles spray from the tiger stripe fractures — evidence that an underground ocean is venting directly into space from beneath the active south polar terrain.

Whether it was caused by an impact or some other process, Tajeddine and colleagues think the disruption and creation of the tiger-stripe terrain caused some of Enceladus’ mass to be redistributed, making the moon’s rotation unsteady and wobbly. The rotation would have eventually stabilized, likely taking more than a million years. By the time the rotation settled down, the north-south axis would have reoriented to pass through different points on the surface — a mechanism researchers call “true polar wander.”

The polar wander idea helps to explain why Enceladus’ modern-day north and south poles appear quite different. The south is active and geologically young, while the north is covered in craters and appears much older. The moon’s original poles would have looked more alike before the event that caused Enceladus to tip over and relocate the disrupted tiger-stripe terrain to the moon’s south polar region.

The results were published in the online edition of the journal Icarus on April 30, 2017.

These maps look toward the southern hemisphere of Saturn’s moon Enceladus, with colors representing highs and lows. Purple represents the lowest elevations, while red represents the highest. The map at left shows the surface of Enceladus in its possible ancient orientation, millions of years ago. The chain of basins representing topographic lows can be seen in blue and purple, running along the equator, with an additional low region around the original south pole. The region that encloses the moon’s currently active south polar terrain, with its long, linear “tiger stripe” fractures, would have been at middle latitudes just south of the equator. The map at right shows the current orientation of Enceladus. Image via NASA JPL.

Bottom line: New research based on Cassini spacecraft data suggests Saturn’s moon Enceladus tipped over in the distant past.

Scott Adams is a tosser, part 2 [Stoat]

18813361_1533741416678444_8062868971593521307_n Scott Adams is suddenly interested in global warming. Why? It isn’t a new issue and he doesn’t really have anything new to say about it. I think the answer is that he has become a Trump fanboi and is running cover for Trump; or is still over-obsessed by his own perspicacity; or perhaps it is just a momentary interest. Or like covfefe we may never know.

Aanyway, having cartooned it once – and not again, and my patience is now exhausted – he’s blogged it a bit, and has finally said something sensible1. Or at least, sensible compared to the rest. And since it is close to one of my hobby horses, I thought I’d parade it in the ring.

SA starts badly with “What the heck is “climate denial”? Is that even a thing?”. Ermm, yes it is. If only all the world’s knotty conundrums could so easily be unravelled. He then continues, in somewhat self-aggrandising terms, to attempt to distinguish GW science from the economics. And if you think that’s a distinction that doesn’t need to be made, then try reading climatecrocks report on the cartoon (although irritatingly cc seems to have just copied then garbled P Z Meyers take; and more irritatingly freethoughtblogs is currently down for me, so that’s an archive of Google’s cache, oh this modern world is so complicated). Anyway, that’s kinda my point. I thought – but didn’t say at the time so I can’t prove this in any convincing way – that the correct answer to SA’s cartoon argument was to point out that not trusting the economic models doesn’t make you a science denier4. The economic models are different, and require different understanding. Arguably, most-to-all states today are indeed economics deniers, because they insist on tariffs not free trade, and on subsidies not carbon taxes3. But you’ve heard that one before.

Trexit

I didn’t really want to say much about Trexit because everyone else already has. How about I just point you at ATTP’s Trump and Paris, which you’ve already read, and say that I agree with most of it. The important thing to do is to not waste your time analysing the reasons Trump gave for leaving. They are all fluff, chaff, smoke and mirrors, and of no importance. The real reasons are the obvious ones: he promised his fanbase he would; Repubs on the whole dislike it and Dems like it; it was an Obama policy. What more reason does he need? This isn’t a thinking president.

Notes

1. Part of what he said that is sensible is hidden in another post, which is Disclosure: My current view on climate science is that the climate scientists are probably right on the basic science, and their climate models are probably directionally right too2. But no one has created a credible economic model around climate change…. It is weak and I think deliberately vague, but at least accepts the science – or fails to dispute it – whilst worrying about the economics.

2. Note that in the cartoon, SA rather obscures this point, by having his scientist say “dozens of different climate models and ignore the ones that look wrong to us”. That’s not quite totally incorrect, but definitely at least misleading in context.

3. And so, dear reader, I suspect, are you. But that doesn’t worry you because of <excuses>. Of course your excuses are good excuses and in no way resemble the excuses that Bad people make for things that you dislike.

4. His continuing point, that this argument is a killer because there are no credible economic models, is simply stupid. Economic models are used all the time for policy making because, imperfect as they are, they are better than nothing.

Recommended music player and radio for the gym [Greg Laden's Blog]

Several weeks ago I tried once again, after many prior ill fated attempts over several years, to get a device that would play music, audio books, and be a radio. The audiobook part wasn’t the most important part, but the ability to play various audio files AND act as a radio AND not be a big giant thing I had to strap to a body part AND be sturdy were all important. This latest attempt has gone very well, and I now have a device that is very nice and therefore, I figured you’d want one too.

This time I tried the AGPtEK M20S 8GB Mini MP3 Player(Expandable Up to 64GB), Lossless Sound Touch Button Metal Music Player with FM/Voice Record,Silver and I love it, enough to recommend it.

Here are some of the specs from the manufacturer:

  • Tiny and Solid Construction: The metal body makes it sturdy with some weight. Mini and portable,only 3 x 0.3 x 1.2 inches.
  • Lossless Sound Quality: High sound quality brings crystal clear sound wherever you are. Support audio formats: MP3/WMA/OGG/APE(Normal/Fast)/FLAC/WAV/AAC-LC/ACELP.
  • Easy Operation with Touch Button: Designed with 6 touch buttons and 5 metal buttons,independent locking and volume control. Fashion and convenient operation.
  • Multi-function: With music play, FM radio, FM/voice recording, resume playback, folder view, clock screensaver, bookmarks etc.
  • Long playback time: Up to 14 hours of audio playback with 2 hours of full charge. 8 GB digital storage media capacity, supports up to 64 GB (not included). To avoid incompatibility, please use AGPTek Memory Card.

Did you see that it holds a microSD? I’ve not used that feature, but that is pretty cool. It has folders you can divide the music up in, which is, essentially, a very efficient way of making a play list. I’ve also not tried to record music off the radio. I’ll probably never listen to music on this radio. I may, however, record Rachel Maddow now and then..

At this point, being fairly new, I think it goes well beyond the 2 hour charge estimate.

It is complicated, this little device, and therefore can not be operated with a single button like a Shuffle. So, it will take a little while to lerarn how to use it (perhaps a full five minutes). Just remember, the reverse U button backs you out, and that’s a great way to change modes. The menu hamburger button, while listening to a radio station, lets you make a preset or change the presets.

I’m not sure that I loved the headphones. I remember not being too impressed with how they fit, but that’s going to be true for everybody vis-a-vis various headphones. I just plugged in my favorite headphones and used them. I’d grab them and look them over one more time to give you my opinion, but it is possible that the cat ate them.

Also, I just noticed, that if you get the AGPtEK now and buy an additional item with it, like a microSD card or a wall charger, you can get a discount on something. I’m not in the market for any of those things so I didn’t look closely.

Just remember, the reverse U button backs you out, and that’s a great way to change modes. The menu hamburger button, while listening to a radio station, lets you make a preset or change the presets.

I’m not sure that I loved the headphones. I remember not being too impressed with how they fit, but that’s going to be true for everybody vis-a-vis various headphones. I just plugged in my favorite headphones and used them. I’d grab them and look them over one more time to give you my opinion, but it is possible that the cat ate them.

Also, I just noticed, that if you get the AGPtEK now and buy an additional item with it, like a microSD card or a wall charger, you can get a discount on something. I’m not in the market for any of those things so I didn’t look closely.
