drorzel | January 25, 2010The great thing about using Google to vanity search for articles about How to Teach Physics to Your Dog, or at least one of the great things about it, is that it's world-wide. Thus, this Dutch roundup of new books, which includes mine. This is what they have to say:
Een erg geestig boek is 'How to Teach Physics to Your Dog'. Chad Orzel gebruikt scenarios uit de echte wereld om kwantummechanica uit te leggen. Dit doet hij dankzij conversaties met zijn hond Emmy. De leuke gesprekken zorgen er voor dat veel vragen worden opgelost over kwantummechanica. Het boek is niet voor de absolute beginner…
drorzel | January 25, 2010As mentioned previously, I've been reading Sean Carroll's Wheel arrow of time book, which necessarily includes a good bit of discussion of "Maxwell's Demon," a thought experiment famously proposed by James Clerk Maxwell as something that would allow you to cool a gas without obviously increasing entropy. The "demon" mans a trapdoor between a sample of gas and an initially empty space, and allows only slow-moving gas atoms to pass through. After some time, the empty volume is filled with a gas at lower temperature than the initial sample, while the gas in the original volume is hotter than…
drorzel | January 25, 2010There was a flurry of stories last week about an arxiv preprint on optical trapping of an ion. Somewhat surprisingly for an arxiv-only paper, it got a write-up in Physics World. While I generally like Physics World, I have to take issue with their description of why this is interesting:
In the past, the trapping of atomic particles has followed a basic rule: use radio-frequency (RF) electromagnetic fields for ions, and optical lasers for neutral particles, such as atoms. This is because RF fields can only exert electric forces on charges; try to use them on neutral particles and there's…
drorzel | January 25, 20102010 marks the 50th anniversary of the invention of the laser. To mark the occasion, the American Physical society has launched LaserFest, which will involve a large number of public events over the next year. The website includes a bunch of cool things explaining the physics of lasers, and a timeline of laser history with one glaring bug that you'll have to figure out for yourself. Over at Cocktail Party Physics, Jennifer Ouellette has an excellent historical survey of her own, saving me a lot of typing.
(Fun fact: Gordon Gould, who eventually won a lengthy patent fight, was a Union alumnus…
oracknows | January 24, 2010Mike Adams is confused.
I know, I know. Such a statement is akin to saying that water is wet (and that it doesn't have memory, at least not the mystical magical memories ascribed to it by homeopaths), that the sun rises in the East, or that writing an NIH R01 grant is hard, but there you go. Speaking of writing an NIH R01, that's exactly what I'm doing now, hence the decreased blogorrhea over the last few days, but sometimes trying to cram a five year project into the 13 pages (one page for specific aims and twelve to describe the project) makes my head hurt so much that reading and…

Here's something new. Instead of trawling youtube to find the Sunday Night Movie, I've made my own. Click above to watch the compressed version, or if you have a speedy connection click here to see it in full HD glory.
I spent the afternoon experimenting with the video capabilities of the new Canon EOS 7d. The 7d is the newest camera in Canon's SLR lineup, and unlike earlier models it can shoot high-definition video as well as stills.
I've been very curious to see how the video performs with my macro lenses. A lab colony of Odontomachus chelifer trap-jaw ants at the University proved patient…
drorzel | January 24, 2010A few weeks back, I spoke on the phone with a freelance writer who was doing a piece for the Albany Times Union. She was putting together a joint article on How to Teach Physics to Your Dog and the Atomville book put together by Jill Linz and Cindy Schwarz (at Skidmore and Vassar, respectively). The piece was published today: "Physics without limits: Area writers explain quantum mechanics to adults, kids."
Unfortunately, the Times Union has a policy of reserving some stories for the print edition, and so there's no way to link to it. So, unless you have a way to get your hands on a paper…

"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 | January 23, 2010Having seen other authors led into destruction by responding to customer reviews on Amazon, I tend to approach the customer reviews of How to Teach Physics to Your Dog with some trepidation.
It turns out, though, that they're really good. And I don't mean that in a Harriet Kalunser kind of way-- the positive reviews are thoughtful and positive, and the negative comments that have been made are for the most part legitimate criticisms of the book. And then there's this one:
My 11 year old son is nuts about physics, so I got this book to see how it would go over with him. It did, perfectly. The…
drorzel | January 23, 2010That's the bill for the time that I spent on deciphering his supposed falsification of decoherence. I don't want anyone to fall for his false argument, so here's the correct explanation of the scenario, to save other people the trouble.
The center of his so-called "proof" is this modified Mach-Zehnder Inteferometer:
Light enters at the lower left, is split by a beamsplitter (which I'm representing as a beamsplitter cube, because that's what I usually use, but it could be anything), redirected by two mirrors to a second beamsplitter where the beams A and B are recombined, then the recombined…
bioephemera | January 22, 2010For minority undergraduates interested in careers in science writing:
The American Association for the Advancement of Science (AAAS) is proud to offer a summer internship program for minority students interested in journalism as a career and who want to learn about science writing. Experience what it's like to cover the scientific and technological issues that shape our global community. The Internship takes place at the Washington, D.C. headquarters of AAAS's Science magazine, the largest interdisciplinary journal in the world. The program is a paid, 10-week experience under the guidance of…
jrosenhouse | January 22, 2010Here's a quote from the book Galileo Goes to Jail and Other Myths About Science and Religion:
In Augustine's influential view, then, knowledge of the things of this world is not a legitimate end in itself, but as a means to other ends it is indispensable. The classical sciences must accept a subordinate position as the handmaiden of theology and religion -- the temporal serving the eternal. The knowledge contained in classical sciences is not to be loved, but it may legitimately be used. This attitude toward scientific knowledge cam to prevail throughout the Middle Ages and survived well…

Have you read an especially good essay about science, nature or medicine lately? If so, why not share it with the world by submitting the URL for this essay to a blog carnival designed to share excellent writing with others? You don't need to be the author of an essay to submit it for consideration, and this is one way that blog carnivals grow in size and influence: by sharing with others.
Scientia Pro Publica (Science for the People) is a traveling blog…
drorzel | January 22, 2010The NSF's Science and Engineering Indicators report came out not too long ago, and the bulk of it is, as usual, spent on quasi-quantitative measures of scientific productivity-- numbers of degrees granted, numbers of patent applications for various countries, etc. I find all of those things pretty deeply flawed, so I tend to skip past them and go straight to the stuff about public knowledge and understanding (chapter 7, available as a PDF at the link above).
This doesn't get much press, probably because the results are depressing. They've asked a bunch of factual knowledge questions of people…
drorzel | January 22, 2010We're once again in the "things are in the pipeline, but nothing has been posted recently" mode, which is a good excuse for some Amazon neepery.
Since the AP review came out, and was printed in 20-odd papers, the sales rank has climbed back into the four digits, and has spent the last few days hovering around 2,000. This is pretty respectable, and Amazon proudly touts it as being "#1 in Books > Science > Physics > Quantum Theory," which sounds nice.
Of course, what does that really mean?
If you click through to the "Quantum Theory" subcategory, you'll see that it's a weird…

Amblyopone australis: a primitive ant?
Earlier I chastised Christian Peeters and Mathieu Molet for misinterpreting the term "basal" in a phylogenetic context. What was that about?
The issue relates to the classic fallacy of viewing evolution as a linear progression from primitive to advanced. Popular conceptions of evolution aside, the process is not linear like a ladder so much as branching like a bush.
I don't know what quirk of human psychology so strongly predisposes us to frame ideas in linear narratives, but the fact that we do so makes evolution an unfortunately difficult concept…
drorzel | January 21, 2010I've mentioned before that I'm going to be giving an invited talk in the LaserFest session at the APS March Meeting. I finally got around to registering for the meeting, and booking my travel. $1,500 on the college credit card-- whee!
The March Meeting program is one of the more intimidating meeting programs I've ever seen-- there are 42 parallel sessions in every time block. Yikes. I thought DAMOP was getting to be a little too big to navigate, but this is ridiculous...
Speaking of DAMOP, I'll also be going to the 2010 DAMOP Meeting in Houston. I haven't booked my travel for that, yet,…
pharyngula | January 21, 2010Times are tight. It's tough getting grants from NIH and NSF, but the government has heard your plight and has responded by opening up new avenues to request support: apply for an NCMHD Innovative Faith-Based Approaches to Health Disparities Research grant!
Purpose. The purpose of the NCMHD Innovative Faith-Based Approaches to Health Disparities Research (R21) is to solicit applications that propose translational and transdisciplinary interventions on health disparities, social determinants of health, health behavior and promotion and disease prevention, especially those jointly conducted with…
drorzel | January 21, 2010Set the bloggy flags at half-mast, for Dave and Greta are shutting down Cognitive Daily. OK, maybe three-quarter-mast, because they're doing it of their own free will, but still, they'll be missed.
And now I need to find a new example of an extremely successful blog that is always and unfailingly about science, with no excursions into politics or media criticism. Suggestions welcome in the comments.
awild | January 20, 2010Let me preface this post by saying that Christian Peeters is one of my absolute favorite myrmecologists. If lost in a remote African jungle and stalked by ravenous leopards, for example, Christian is the first ant guy I'd pick to help get me out of the predicament.
Having said that, this paper in Insectes Sociaux is so bad I nearly gouged my eyes out and ran around in little circles screaming and flailing my arms.
Nonetheless there exist extant ants with relatively simple societies, where size-polymorphic workers and large queens are absent. Recent phylogenies show that the poneroid…
