pharyngula | December 6, 2009It's an odd thing that when people list great science popularizers of the past, names like Sagan and Feynman always pop up, but most people seem to have forgotten Isaac Asimov, who wrote some fabulous essays on understanding science. Here's one example, in which he addresses a claim we hear all the time, that the errors of the past mean our knowledge now is on very shaky ground. He's answering a complaint from an English Lit student who chastised Asimov for thinking he knew anything at all.
The young specialist in English Lit, having quoted me, went on to lecture me severely on the fact that…

Origami is as ephemeral as art gets - delicate paper, with no more than creases and physics to maintain its shape. It's also the ideal art form for blurring the boundary between art and science, because it's all about geometry. You could argue that the origami medium is math, just as much as it's paper.
That's why Between the Folds, a documentary film by Vanessa Gould about origami-happy artists, mathematicians and scientists "working in the shadows between art and math," is such a success: the connections between math, science, art and paper aren't strained at all, so you can sit back and…

"How does one distinguish a truly civilized nation from an aggregation of
barbarians? That is easy. A civilized country produces much good bird
literature."
--Edgar Kincaid
The Birdbooker Report is a special weekly report of a wide variety of science, nature and behavior books that currently are, or soon will be available for purchase. This report is written by one of my Seattle birding pals and book collector, Ian "Birdbooker" Paulsen, and is edited by me and published here for your information and…
drorzel | December 6, 2009I'm kind of fried from all the recent driving, and I've got some stuff to catch up on. So we'll ease back into regular blogging, by posting a clip from last week's Colbert Report with everybody's favorite Jesuit, Brother Guy Consolmagno, talking about how alien life would affect Christianity:

The blog carnival submission form has been having problems sending submissions to the proper blog carnival email addresses, so Scientia pro Publica has ONE submission so far -- and it publishes TOMORROW!! If you have sent a submission to this carnival, PLEASE resend it immediately! I am hoping all of you come through my sending at least one science-y submission (yours or other people's) to this carnival ASAP to help out the host so she doesn't pull all her hairs…
oracknows | December 5, 2009My benevolent overlords at Seed Media Group yesterday announced (to me at least) a surprise new initiative. But, then, I'm always one of the last to find out about these things. In any case, it would appear that we're teaming up with National Geographic to share blog content and various other initiatives. The press release describes what's going on:
NATIONAL GEOGRAPHIC DIGITAL MEDIA AND SCIENCEBLOGS.COM FORM STRATEGIC PARTNERSHIP
WASHINGTON / NEW YORK (Dec. 3, 2009)--National Geographic Digital Media (NGDM) and ScienceBlogs.com today announced that they have formed a strategic partnership…

Oddly enough, a photograph I took in 2007 has been chosen as one of Popular Science's 2009 "The Year's Most Amazing Scientific Images" (I'm #34 in the gallery). I guess that's because the image wasn't widely distributed until the NY Times picked it up earlier this year. Not that I'm complaining, of course.
My favorite image in Popular Science's lineup is this one, a spectacular confluence of lightning and volcanic eruption captured by Carlos Gutierrez. But there are plenty of other stunning images in the gallery. Go see.

Pogonomyrmex micans, stack of 23 images using CombineZP. Click for large file.
I don't ordinarily do product endorsements on the blog, but here's one: the image-stacking software CombineZP. I recommend it for two reasons. First, CombineZP produces smoother, more artifact-free images than the very expensive competition. Second, CombineZP is freeware. Alan Hadley, a British arthropod enthusiast, wrote it in his spare time.
Good. And free. Not much to argue with there.
CombineZP and similar products are designed to counter a major challenge of macrophotography, the narrow depth of…

Voss-Andreae is therefore either brave or foolhardy to try to represent quantum phenomena tangibly. Perhaps his greatest asset as a former physicist is that he realizes how much we don't know. In some of his works, the inverted commas of analogy are explicit to the knowing eye. Quantum Corral (pictured) materializes something that could hardly be less material: the wave-like properties of electrons, first reported in Nature in 1927. Here, they are represented in a block of wood that has been milled to the contours of electron density seen in 1993 around a ring of iron atoms on the surface…
awild | December 3, 2009Here's an issue that's been on my mind as I'm shuffling trees around from several concurrent phylogenetic projects.
The primary output from phylogenetics programs is tree diagrams depicting the relationships among organisms. Very clean, very crisp, very precise diagrams. Precision isn't in itself a problem, but for the human foible of mistaking precision for accuracy.
I'm not interested in a precise estimate of evolutionary history so much as a correct one. I'm reminded as much when I see my estimates change from one precise conclusion to another as I add more data from more species. …
drorzel | December 3, 2009I spent an inordinate amount of time yesterday reading an economics paper, specifically the one about academic salaries and reputations mentioned on the Freakonomics blog. There's a pdf available from that post, if you'd like to read it for yourself.
The basic idea is that they looked at the publication records of several hundred full professors of economics, and publicly available salary data for many of the same faculty, and tried to correlate those with the "reputation" of the professors in question. They used a couple of indirect means to assign each faculty member a "reputation," mostly…

If It Weren't For You (I'd Be Sued) from Justine Cooper on Vimeo.
Yes, that was a . . .
music video in which an unseen clinician serenades the mannequins used in medical simulation with an infectious rock ballad. Emoting on the depth of their relationship, the doctor or nurse apologizes to the mannequins for what they go through in the name of patient safety and the improvement of clinical skills, crooning the chorus "If it weren't for you, I'd be sued."
It turns out the video is just part of…
drorzel | December 2, 2009I've made a couple of oblique references to this over the past couple of months, but I have an article in the new issue of Physics World, on experiments using molecules to search for an electric dipole moment of the electron:
When most of us think about searching for physics beyond the Standard Model - the dominant paradigm of particle physics - the first thing that springs to mind is probably a gigantic particle accelerator like CERN's Large Hadron Collider (LHC). Within the collider's 27-km loop, protons slam together at 99.9999991% of the speed of light. Office-building-sized detectors…
bioephemera | December 2, 2009As many of you know, I've been working for the past couple of years on youth internet health and education issues. While the stereotype is that younger = tech savvier, that's not strictly true. Younger kids may be better acquainted with the internet, may use it more, and may feel more comfortable with it, but that doesn't necessarily mean they have the cognitive skills or experience to differentiate between manipulative content, unreliable content, and good content.
How many of you, as adults, have been tricked into clicking on a deceptive banner ad that looked like genuine content? How many…
drorzel | December 2, 2009The big topic-of-the-moment is the hacked stash of emails from a major climate research group. The whole climate change discussion is one of those "no upside" topics that I try to stay out of, but I have some thoughts and comments about issues surrounding the email incident. These are largely based on reactions to yesterday's posts by Derek Lowe and Coby Beck, so if you're looking for something to read to understand what I'm talking about, those are the two.
The unifying thing in all of these is the intersection of science and politics. Most of what's described is normal scientific behavior…

Cephalotes grandinosus, an herbivorous ant
Why are there so many ants?
This is a more perplexing question than it may seem. At first glance ants are predators and scavengers. Yet predators should be few in number, balanced on a narrow trophic peak and depending on high prey biomass to exist. Why are terrestrial ecosystems dominated by these little hunters?
A landmark study several years ago by Dinah Davidson provided an answer: many ants are not predators at all. They're herbivores. Sure, they snack now and again on flesh. But ants get most of their energy from plants, either…
pharyngula | December 1, 2009So true and so hilarious: a study has found that god speaks with a remarkably egocentric voice. In tests that asked people what god's opinion of various matters was, the unsurprising discovery was that it was the same as the individual's opinion — and of course every person's opinion was different. You'd expect some consistency if they were all hearing god's word, you would think!
It fits with the typical vision of the sockpuppeteer, too: the loser whose opinions are indefensible, so he invents an army of aliases to agree with him. And what more powerful sockpuppet could there be than to have…
drorzel | December 1, 2009Back during the DonorsChoose fundraiser, I promised to do a re-enactment of the Bohr-Einstein debates using puppets if you contributed enough to claim $2,000 of the Hewlett-Packard contribution to the Social Media Challenge. I obviously aimed too low, because the final take was $4064.70, more than twice the threshold for a puppet show.
So, I put together a puppet show. It took a little while, because I couldn't find any Niels Bohr puppets (maybe in Denmark?). I found an acceptable alternative, though, and put together a video of the Bohr-Einstein debates, using puppets. Here's the whole thing…
drorzel | December 1, 2009The Royal Society has launched a spiffy new site that lets you browse highlights of the last 350 years of science as published in the Philosophical Transactions ("Giving Some Accompt of the Present Understanding, Studies, and Labours of the Ingenious in Many Considerable Parts of the World since 1665."). These include things like Ben Franklin's very matter-of-fact instructions for flying a kite in a thunderstorm, Thomas Young's introduction of the wave theory of light, and Maxwell's original treatise on electromagnetism. These are available as scanned PDF's, in all their oddly-typeset glory (…

Thylacine Dingo Comparison
Carl Buell
In Slate, Matt Gaffney explains how the constraints of a given system - in this case crossword puzzles - may lead to suspiciously similar yet independent solutions. Gaffney wrote a Poe-themed crossword with the elements BRAVE NEW WORLD, INTRAVENOUS DRIP, CONTRAVENE, COBRA VENOM, and VENTNOR AVENUE (all of which have "raven" embedded in them). He was very proud of his puzzle, but. . .
I soon learned that I wasn't as clever as I thought. Over the next couple of days, I started getting e-mails from solvers telling me that my theme had been done before. In…
