mikethemadbiologist | January 27, 2009Our Benevolent Seed Overlords ask "What is science's rightful place?" which refers to a line from Obama's inaugural address where he vowed to "restore science to its rightful place."
Since ScienceBlogling Jake discussed the importance of basing policy on evidence--as well as correctly recognizing that the method we use to solve problems does not shed much light on whether we should address those problems in the first place--I want to bring up one problem that science faces: it is, to a great extent, elitist.
Before all of the TEH SCIENTISMZ R EVUL!!! crowd gets all hot and bothered, what I…

Supernova: The Violent Death of a Star
Massive stars end their lives in spectacular supernova explosions, visible across the Universe, that blast material into space that contributes to future generations of stars, produces cosmic rays, and stirs up interstellar gases. Many heavy elements, including the calcium in our bones and trace amounts of copper and zinc in our bodies, are formed only in supernovae; we are quite literally made of star stuff. Some supernovae can even be used to gauge distances to remote galaxies; from these we have learned the…
clock | January 26, 2009Secrets Of Stradivarius' Unique Violin Sound Revealed, Professor Says:
For centuries, violin makers have tried and failed to reproduce the pristine sound of Stradivarius and Guarneri violins, but after 33 years of work put into the project, a Texas A&M University professor is confident the veil of mystery has now been lifted. Joseph Nagyvary, a professor emeritus of biochemistry, first theorized in 1976 that chemicals used on the instruments - not merely the wood and the construction - are responsible for the distinctive sound of these violins. His controversial theory has now received…
drorzel | January 20, 2009This is flagged as a ResearchBlogging post, but it's a different sort of research than I usually write up here, as this is a paper from Physical Review Special Topics-- Physics Education Research. This is, however, a legitimate and growing area of research in physics departments, and some of the findings from the PER field are really interesting.
This particular paper, though, is mostly kind of depressing. The authors, including Nobel laureate Carl Wieman, gave students in three introductory physics classes a survey about their attitudes toward physics. They asked the students to indicate…
sporte | January 19, 2009One of the newfangled ideas that's popped up in education in the past few years has been notion that more interactive methods of teaching will lead to better results.
There's an appealing logic to this notion.
Figure 1. A traditional lecture may not be the ideal way to transfer information.

To quote Eric Mazur (1) quoting D. Huff (2):
I once heard someone describe the lecture method as a process whereby the lecture notes of the instructor get transferred to the notebooks of students without passing through the brains of either…
catdynamics | January 15, 2009The proposed economic stimulus package includes some funding for science.
Chunk for NSF, lot of facility funding.
NASA gets climate science.
DoE gets some toys.
Appropriations Stimulus 0115 (pdf)
The total package is somewhere in the $800+ billion range, as proposed.
With about 1/3 proposed as tax cuts, the rest short term supplemental funding.
$10 billion is for science, largely for facilities and refurbishment. Mostly NSF and NIH.
Looks like this is a two year (effectively 18 months since much of '08-09 fiscal year will be gone if-and-when it passes) package, and then we ramp to regular…
drorzel | January 13, 2009The scare quotes in the title are to distinguish "Modern Physics" classes like the one I'm teaching this term from modern physics as a general subject, which, of course, all right-thinking people should study in depth. The question comes from a comment by Coriolis on last week's post about what "Modern Physics" is as a class:
Having passed through those classes (I'm now a grad student), I have to say I didn't see much worth in the Modern physics class (and your description of it is pretty much how I remember it, except without the relativity). It's basically in that middle ground trying to…
oracknows | January 9, 2009Three weeks ago, I reintroduced my readers to one of the most amazingly skilled weaver of woo tales who has ever lived. I'm referring, of course, to Lionel Milgrom, the man who can pepper his homeopathic woo with quantum nonsense the way Bobby Flay seasons his latest creation with various spices. Now, I'm about to admit a huge hole in my knowledge here. I realize that it seems simply unbelievable that I would have a hole at all in my knowledge, much less a major hole, but there you are. Not even cranky supercomputers are perfect, I guess.
The huge hole in my knowledge revealed by my…
drorzel | January 8, 2009In the "uncomfortable questions" comment thread, Thony C. suggests:
You say you're teaching "modern physics" so how about a running commentary on the stuff your teaching?
That's a good suggestion, and I'll start posting some sketchy reports soon. First, though, Bora asks:
What is un-modern physics?
Roughly speaking, physics gets divided into "Classical Physics" and "Modern Physics," with the dividing line coming right around 1900.
"Classical Physics" basically covers fields that were well established before 1900: Newtonian Dynamics, Electricity and Magnetism, most of Thermodynamics, most of…
oracknows | December 22, 2008The zombie has arisen once again to eat the brains of the Air Force.
I'm referring to so-called "battlefield acupuncture," a topic that I wrote about last week for this very blog. I didn't think there'd be a reason to revisit the subject again so soon, but I was wrong for three reasons. First, I remain appalled at how one ideologue, Col. (Dr.) Richard Niemtzow, a radiation oncologist and Air Force physician turned woo-meister-in-chief and number one advocate of acupuncture use in the military, has succeeded in introducing acupuncture into not only formerly hard-nosed and science-based…
oracknows | December 19, 2008I'm a connoisseur of woo.
It's true. Back when I first started blogging, I came across outrageous bits of pseudoscience such as the ones I feature periodically on Your Friday Dose of Woo, and I wasn't sure quite what to do with them. Indeed, I had a hard time deciding if some of them were massive Sokal-type hoaxes or evenif the person writing them really believed in them. Of course, I had a lot of fun taking them on. How could I not? After all, what else can one make of something like, for example, DNA Activation or "healing sounds," or even for that matter that unholy alliance of…
purepedantry | December 18, 2008I doubt it...but more on that in a second.
There is a fascinating argument going over at Edge.org about whether science can save the economy. The authors suggest that the scientific techniques being applied to the natural sciences should be applied to establish a new consensus about how the economy works:
In the near-term, Eric Weinstein has spoken about an "economic Manhattan project". This means getting a group of good scientists together, some who know a lot about economics and finance, and others, who have proved themselves in other areas of science but bring fresh minds and perspectives…
clock | December 15, 2008Pawel tried, for a year, to be a freelance scientist. While the experiment did not work, in a sense that it had to end, he has learned a lot from the experience. And all of us following his experience also learned a lot about the current state of the world. And I do not think this has anything to do with Pawel living in Poland - I doubt this would have been any different if he was in the USA or elsewhere.
You all know that I am a big fan of telecommuting and coworking and one of the doomsayers about the future existence of the institution of 'The Office'. And you also know that I am a…
apalazzo | December 14, 2008Welcome to the December 14, 2008 edition of the Molecular and Cell Biology Carnival.
Below the fold, we have a great compilation of entries to share with you.
I would like to start off by reminding you that today marks the beginning of the American Society for Cell Biology's annual conference in San Francisco. Although I won't be there, biowrites, the new blog over at the Journal of Cell Biology, will be covering the main events, so check it out.
Next, Charles Daney who blogs at Science and Reason writes about Non-coding RNA and gene expression. The post covers a recent publication by Kouji…
tlambert | December 13, 2008Inhofe's list of 650 scientists that supposedly dispute the consensus on AGW reminded me of another list: The Discovery Institute's list of scientists who dissent from Darwinism, so I thought I'd compare the two lists.
First, numbers. The Discovery Institute's list has 751 names, while Inhofe's has only 604. (Not "More Than 650" as he claims -- there are many names appearing more than once.)
Second, how do you get on the list? Well, you have to sign up to get on the Discovery Institute's list, but Inhofe will add you to his list if he thinks you're disputing the global warming consensus and…
tlambert | December 11, 2008Last year Inhofe released a list of 400 scientists who disputed mainstream climate science. But as Joe Romm and Andrew Dessler observed, the list was padded with TV weathermen, economists and so on and contained very few actual climate scientists. Now he's back with more of the same in a new list that adds 250 more names. Update: Joe Romm takes apart the new list. My favorite entry (reproduced in full so you can get the full nutty flavour):
Field Geologist Louis A.G. Hissink is the editor of The Australian Institute of
Geoscientists Newsletter and is currently working on the ore-reserve…
oracknows | December 10, 2008
I have to wonder if the most famous denizen of the Discovery Institute in medical circles, Dr. Michael Egnor, is on vacation or something. For some reason, he's been especially active over at the Discovery Institute's repository of pseudoscience, Evolution News & Views, over the last couple of weeks. Neurosurgeons tend to be very busy people, more so even than a humble breast cancer surgeon like me, and few are as motivated as I am to blog. Yet, these days Dr. Egnor's been flooding EN&V with more of his blather than I've seen him do in a long time, maybe ever.
It's times like these…

oracknows | December 9, 2008My original post that asked the intentionally provocative question Was Nazi science good science? provoked a lot of comments, some of which made me think, which is good. This post was inspired by an article in which historian of the Nazi era Richard Evans was featured in a story about Nazi science and expressed his amazement at how much Nazi science was treated just like any other science, with little or no comment by other scientists of the era about the completely unethical and downright evil nature of the experiments, which reduced human beings to the status of laboratory animals, and…
drorzel | December 8, 2008I made a run to the library last week on one of the days I was home with SteelyKid, as an excuse to get out of the house for a little while. I picked up three books: Counterknowledge, The Devil's Eye by Jack McDevitt (an Antiquities Dealers Innnnn Spaaaaaace novel, and a good example of Competence Fiction), and a pop-science book titled The Age of Entanglement: When Quantum Physics Came of Age by Louisa Gilder, because it looked fairly relevant to my own book-in-progress.
Amusingly, my RSS feeds yesterday brought me the latest in a series of posts in which ZapperZ waxes peevish about the book…
