catdynamics | May 7, 2008The Chaiten Volcano in Chile is erupting, first time in at least 2000 years, more likely the last eruption was about 10,000 years ago.
The eruption is intensifying and local towns are being evacuated

GDACS has issued a Green Alert
International Volcano Research Centre has more info
Ok, nice volcano, low population density, and Chilean navy seems to have the evacuations under control. Currently spouting ash.
The interesting thing is that the last eruption was a Caldera forming explosion of unknown strength, but indirect evidence puts it on the large eruption…
catdynamics | May 6, 2008The news from Tropical Cyclone Nagris keep coming and getting worse
Earth Observatory shows what happened
(click for hi-res aftermath image).
Chris at the Intersection keeps good running updates, and, we should remember, noted the threat the storm presented early last week!
Jeff Masters at the Weather Underground also has good information.
As Masters notes, the storm hit the heavily populated Irrawaddy delta where the spring rice harvest is just coming in.
This means likely significant loss of crop, with local shortages until the autumn crop comes in.
Myanmar is also a significant rice…
esiegel | May 6, 2008(This is adapted from my public lecture, Afraid of the Dark: How We Know What We Can't See.)
Let's go back over 200 years ago, to 1781. William Herschel (left) discovered the planet Uranus, noticing that an object, as bright as a star, was actually moving relative to the other stars. The other five inner planets (besides Earth) were known for over 2000 years before that. But it was thought for a long time that Saturn was the farthest one.
But it clearly isn't; as you can see with modern telescopes, Uranus is a super-interesting planet, rotating on its side, surrounded by rings and moons.…
drorzel | May 5, 2008As I'm driving down the street, a squirrel darts out into the road a block or so ahead of me. From the back seat, the dog says "Gun it!!!! Hit the squirrel, hit the squirrel, hitthesquirrel!"
"Will you sit down and be quiet?" We're having some work done on the house, and I'm taking her to work with me so she's not underfoot for the contractors.
The squirrel makes it to the other side of the road, and up a tree to safety. "Awwww," says the dog. "Dude, you totally could've gotten that one. This car is way faster than a stupid squirrel."
"That may be, but I have a class to teach today. I don't…
oracknows | May 5, 2008That's the message that Ben Stein has been pushing lately, namely not just the hated "Darwinism" but science itself inevitably leads to political philosophies such as Nazi-ism and Stalinism (but especially Nazi-ism, given its emphasis on racial hygiene and eugenics), including the mass murder that resulted from them. As a result, Stein has been correctly and deservedly excoriated not just by science bloggers, but even by fellow conservatives such as Instapundit, who characterized Stein as "totally having lost it," and John Derbyshire, who correctly characterized Stein's lies as a blood libel…
oracknows | May 3, 2008Does anyone remember a few months ago, when I wrote about Ben Stein? No? Here, then, I'll jog your memory. Ben Stein and his involvment in that piece of cinematic excrement Expelled! "inspired" me to--if you'll excuse the term--resurrect a certain recurring character from the very early days of this blog. Yes, I'm talking about the ever-dreaded Hitler Zombie, who returned after more than a year's absence to take a huge chomp out of Ben Stein's brain.
Now we're seeing the results of that chomp, and I'm not just talking about the ridiculous claims in Expelled! that "Darwinism" leads inevitably…
drorzel | May 2, 2008I'm going to be busy all day (more or less) at the Steinmetz Symposium, listening to talks about the fantastic things our students have been doing with their research projects. So it's going to be a "talk among yourselves" day here at Uncertain Principles, for the most part.
It's been a little while since I ran a Dorky Poll thread, mostly because I'm running low on topics. Here's one that may be a little too esoteric, inspired by looking at the diploma on my wall:
Chemical Physics, or Physical Chemistry?
For bonus points, what's the difference between them?
Also, are there other pairs of…
pharyngula | May 1, 2008I must urge you to steal buy this book: Illustrated Guide to Home Chemistry Experiments: All Lab, No Lecture (amzn/b&n/abe/pwll). The description makes it sound perfect.
Laboratory work is the essence of chemistry, and measurement is the essence of laboratory work. A hands-on introduction to real chemistry requires real equipment and real chemicals, and real, quantitative experiments. No existing chemistry set provides anything more than a bare start on those essentials, so the obvious answer is to build your own chemistry set and use it to do real chemistry.
Everything you need is…
drorzel | May 1, 2008Speaking (as we were) of pro-science film festivals, Sigma Xi (the scientific research honor society-- think Phi Beta Kappa for science nerds) is announcing a student film competition:
In conjunction with a year-long focus on the issue of water, Sigma Xi is sponsoring a competition for three-minute student films on aspects of this precious and dwindling natural resource. The entry deadline is September 1, 2008.
Prizes of $1,000, $800 and $500 will be awarded for the top three films. The competition is open to undergraduate and graduate students, either individually or in teams. There is no…
drorzel | May 1, 2008Having suggested an on-line pro-science film festival a little while ago, I should report that there are discussions underway (or at least in the works) about trying to make something happen. If it goes anywhere, it may look different than the original suggestion, but I'm kind of curious about one aspect of the original idea.
If you recall, my original suggestion was that we could arrange a film festival using YouTube for the submission and distribution of entries, and basically passing the hat to get a prize pool. I still sort of like the idea of funding it via direct contributions rather…
drorzel | May 1, 2008One of the interesting things to come out of the switch to Matter & Interactions for our intro classes has been some discussion among my colleagues of how the books treat specific topics. A couple of people have raised concerns that the coverage of certain topics is different from the traditional presentation, in a way that isn't entirely accurate.
This is interesting to me not because it calls the books into question, but because the standard treatments of these things aren't entirely accurate, either. Both the new book and the older book are full of lies-to-children.
"Lies-to-children"…

Crypticerya bursera Unruh 2008
Baja California
Cory Unruh describes a new species of scale insect in the genus Crypticerya in this week's Zootaxa. The diagram above shows a highly stylized version of the back (at left) and underbelly (at right) of the insect, with peripheral illustrations of the various pores, appendages and hairs. Scale insects have such an unusual morphology that the people who work on them have had to create a unique system for keeping track of their various characters. Most entomologists- myself included- require additional training to make sense of it.
Like all scale…

I may have joked a bit about certain surgeons whom, because they say such dumb, pseudoscientific things with alarming regularity, I consider embarrassments to the noble profession that is surgery. Usually, it's been surgeons who reveal an astonishing ignorance of the science of evolution as they parrot long discredited and debunked canards about evolution while spouting creationist nonsense. You know about whom I speak: surgeons like neurosurgeon Dr. Michael Egnor and general surgeon Dr. Henry Jordan. But, as mind-numbingly dumb as some of the things that, for example, Dr. Egnor has said…
zooillogix | April 30, 2008Back in March of 2007, we brought you the story of an enormous (colossal really) squid, captured by New Zealandish fishermen and brought back for examination at the University of New Zealand. The frozen squid posed challenges for the researchers who realized that it would take so long to thaw that the outer parts would be rotting before the core had even melted (also an appropriate description of my brother Benny's heart).
Well the marine biologists made their move today, thawing out the colossal squid in a bath of cool water. Had the water been too hot, they were worried it might crack the…

Do as he says.
This is another episode of linking: because linking is an inherent public good.
drorzel | April 30, 2008The Mad Biologist, like 80% of ScienceBlogs, is mad at Chris Mooney:
Here's the problem: you keep coming to evolutionary biologists with a problem (the perception of evolutionary biology), and you don't have a solution. Do you think there's a single evolutionary biologist who is happy with public opinion regarding evolution and creationism? But you're not giving us concrete solutions.
Between teaching and research, along with all of service obligations expected of us (including public outreach), we have too much to do. When we are then told that we need to somehow organize a pro-…
drorzel | April 30, 2008Randy Olson's movie A Flock of Dodos comes up again and again in the course of arguments about public communication of science, but I had never gotten around to seeing it. I finally put it on the Netflix queue, and ended up watching it last night.
For those who have been living in caves and haven't seen this blogged a thousand times, A Flock of Dodos is a documentary about the "intelligent design" fight, primarily in Kansas, where Olson is from. Using the school board debate over science standards as a frame, Olson sets out to learn about "intelligent design," its promoters, and why we're…
pharyngula | April 30, 2008My last Seed column is online, which reminds me (as if I weren't uncomfortably aware already) that I have to finish up the next one today, which actually isn't the next one, which is already done and submitted, but the one after that. These long leading deadlines force one to live a few months in the future…
You know, if you subscribed to the print magazine, you'd be halfway to my future already instead of living in my distant past.
drorzel | April 29, 2008Via the Zeitgeist, the Templeton Foundation has asked a bunch of famous smart people "Does science make belief in God obsolete?" I wouldn't ordinarily note this, but if you scroll down a little, you'll find my thesis advisor, Bill Phillips, who offers an "Absolutely Not!":
[A] scientist can believe in God because such belief is not a scientific matter. Scientific statements must be "falsifiable." That is, there must be some outcome that at least in principle could show that the statement is false. I might say, "Einstein's theory of relativity correctly describes the behavior of visible…
drorzel | April 29, 2008We had a talk yesterday at lunchtime from an alumnus who graduated with a physics degree, got a Ph.D. in Physics, did a couple of post-docs, and then decided to give academia a miss, and went to Wall Street where he's been a financial analyst for the last 12 years. He talked, mostly for the benefit of students, about his path to the world of finance, and what's involved in financial jobs.
This was terrifically interesting, and really useful. Given the way academia works, people who manage to get tenure-track faculty positions almost never have any first-hand experience of the other career…
