Chemistry Comes Alive!

Nitrogen TriIodide Detonation Why didn’t I know about this site before? Chemistry Comes Alive! has movies of some dangerous chemical reactions. These are the reactions that turned me into a chemist, and I’m reasonably sure that a large fraction of our nation’s chemists chose this career path because it was a socially acceptable outlet for teenage pyromania.

The nitrogen triiodide detonation movie has particular resonance with me, but don’t tell my high school chemistry teacher which of her students blew out the locks to the classroom door, OK?

The thermite reaction would be a nice addition to the site.

Codase: Another source code search site

A while back, we mentioned a new open source search site called Koders. A comment to that post describes a new site called Codase which also searches across many open source projects. Here’s a sample search for the word “fourier”.

Stellarium

Today we have a new user-suggested link to Stellarium, an open source desktop planetarium that uses OpenGL to render realistic views of the stars. This looks like a wonderful new program to join our Astronomy section.

Check it out!

Stellarium

Stellarium is an open source desktop planetarium for Linux/Unix, Windows and MacOSX. It renders the skies in realtime using OpenGL, which means the skies will look exactly like what you see with your eyes, binoculars, or a small telescope. Stellarium is very simple to use, which is one of its biggest advantages: it can easily be used by beginners.
Find Stellarium at: http://www.stellarium.org

The know-nothings

Salon is running an article by Andrew O’Hehir called The know-nothings. This is a lengthy and expanded review of Chris Mooney’s book “The Republican War on Science,” although it goes into topics not covered in great detail by Mooney. The article is a good read and has made me anticipate the UPS truck bringing my copy of Mooney’s book. Here’s an excerpt:

Perhaps most effectively of all, the right’s war on science has exploited the mainstream media’s fetish for journalistic “balance,” regardless of its relevance to reality. Despite the overwhelming consensus of mainstream science on global warming, newspaper articles and TV reports still dutifully call upon the shrinking universe of contrarians like Michaels. (Like most climate change skeptics, Michaels has slowly retreated, along with the polar icecaps. He used to claim that global warming either wasn’t happening or wasn’t caused by human activity; now he admits to both, but argues that it can’t be stopped and that its potential effects have been exaggerated.)

Themepunks

I’ve been a Cory Doctorow fan since reading Craphound sometime in the late 90s. Not all of his stories click with me, but he’s the kind of science fiction writer that does a great job synthesizing new ideas from the cultural ether, and new ideas are the reason I read science fiction. He also “gets” open source, and has placed some of his work under Creative Commons licenses.

Anyway, Cory has a new story called Themepunks that is being serialized in Salon magazine.

polyXmass

Filippo Rusconi wrote to me about polyXmass, a GPL-licensed software suite for use in mass spectrometry, specifically for use with (bio-)polymers. This program is somewhat lonely in our Analytical Chemistry section, so if any of our readers know of other open source software for Analytical Chemistry, stop by and suggest an Analytical Chemistry link.

72hours.org

Northern Indiana isn’t prone to hurricanes, earthquakes or many major disasters, but we do get the occasional tornado, and a few years ago we had an ice storm that knocked out power in our neighborhood for a few days. And after the events of the past few weeks, I’ve been thinking a lot about preparing for disaster.

www.72hours.org is a site on disaster preparedness that has been put up by the San Francisco Office of Emergency Services. It is 100 times better than anything I’ve seen from the DHS site.

So what would you take with you in an emergency? Manual can openers and fresh water seem to be pretty important. But what else? A hand-cranked laptop recharger? The CRC handbook of Chemistry & Physics?

Don’t dumb me down

There’s a wonderful Bad Science column by Ben Goldacre in the Guardian all about media coverage of science and why media reports on science are uniformly horrible. Here’s an excerpt:

Science stories usually fall into three families: wacky stories, scare stories and “breakthrough” stories.

Goldacre provides a nearly complete taxonomy of the types of mass media reports on science that you are likely to find. There’s this mini-rant which should be framed and handed out to any scientist who is talking to a journalist:

Last month there was an interesting essay in the journal PLoS Medicine, about how most brand new research findings will turn out to be false. It predictably generated a small flurry of ecstatic pieces from humanities graduates in the media, along the lines of science is made-up, self-aggrandising, hegemony-maintaining, transient fad nonsense; and this is the perfect example of the parody hypothesis that we’ll see later. Scientists know how to read a paper. That’s what they do for a living: read papers, pick them apart, pull out what’s good and bad.

Scientists never said that tenuous small new findings were important headline news – journalists did.

There’s too much good stuff in the column to excerpt any more. Go read the whole thing!

Update: I just found out that Goldacre has his own blog at badscience.net where he’s posted the article with space for reader coments.

Vigyaan

Pratul Agarwal just released version 1.0 of his Vigyaan CD. This is a single CD image with many precompiled tools for bioinformatics, computational biology, and computational chemistry. Just a sample of what’s already there:

  • Arka/GP
  • Artemis
  • BLAST
  • ClustalX
  • Garlic
  • GROMACS
  • Jmol
  • MUMer
  • PSI3
  • PyMOL
  • Ramachandran plot viewer
  • Rasmol
  • Seaview
  • TINKER

This looks like a great tool for both beginners and experts. Check it out!
