oracknows | June 13, 2011Orac note: Grant season is in full swing, and that's what I spent my weekend doing: writing grants. Consequently, here's a rerun from, hard as it is to believe, four and a half years ago. It's the first appearance of one of the most hilarious "alt-med" attacks on science-based medicine I've ever seen, calling us "microfascists." Unfortunately, little has changed coming from CAM supporters in the nearly five years since I first applied some not-so-Respectful Insolence to this little chew toy of an article. Enjoy, I hope. Remember, if you haven't been reading at least four and a half years, it'…
drorzel | June 10, 2011If you look at the schedule of events for DAMOP next week, you will see that there is a movie showing scheduled for Tuesday night: Real Genius. This seems like an excellent excuse to run a poll:
Real Genius is:survey software
While the meeting will largely involve quantum mechanics, this is a purely classical poll, so you can choose only one answer, not a superposition of multiple answers.
oracknows | June 9, 2011Whenever I call an anti-vaccine activist "anti-vaccine," frequently there will be an indignant response along the lines of either, "I'm not 'anti-vaccine'; I'm pro-safe vaccine" or "I'm not 'anti-vaccine'; I'm a vaccine safety activist." (This latter retort is a favorite of Barbara Loe Fisher.) Another favorite retort is, "I'm not 'anti-vaccine'; I'm for 'informed consent'" or "I'm not 'anti-vaccine'; I'm for freedom!" (Imagine the person saying this looking like this the photo below.)

Not infrequently, it doesn't take very long to…
drorzel | June 9, 2011While it is not yet officially summer, according to astronomers and horologists, it was approximately the temperature of the Sun here in Niskayuna yesterday, so de facto summer has begun. Accordingly, we have acquired a pool:
Of course, one of the main things you do with a pool is to sit next to it and read in the sun (note the conveniently positioned chair). Of course, then the question becomes "What do you read?
While the obvious answer is How to Teach Physics to Your Dog (now in paperback!), we got a good thread out of non-obvious suggestions for science-related "beach reading" last year…
drorzel | June 7, 2011I have to admit, I'm writing this one up partly because it lets me use the title reference. It's a cool little paper, though, demonstrating the lengths that physicists will go to in pursuit of precision measurements.
I'm just going to pretend I didn't see that dorky post title, and ask what this is about. Well, it's about the trapping and laser cooling of thorium ions. They managed to load thorium ions into an ion trap, and use lasers to lower their temperature into the millikelvin range. At such low temperatures, the ions in the trap "crystallize."
So, they've demonstrated that if you get…
drorzel | June 7, 2011Over at Dynamics of Cats, chief herding theorist Steinn has a post on what we know about how to teach physics:
To teach physics well, you provide an intensive, mathematically rigorous in-sequence series of classes.
You need at least two different parallel classes per term, each class a prerequisite for the succeeding class and coordinated syllabii for parallel and successive classes, providing an initial short review of the previous material.
You also need a parallel sequence of coordinated mathematics classes, such that the mathematics needed for a physics class are taught before it is…
oracknows | June 6, 2011I've frequently been critical fo the National Center for Complementary and Alternative Medicine (NCCAM) for funding dubious studies of pseudoscience and, in essence, promoting unscientific quackademic medicine (is there any other kind?) by giving it the patina of seeming respectability. I can't recall how many times I've seen promoters of woo justify their woo by saying, "Well, NCCAM funds it." As far as apologetics for quackademic medicine, "NCCAM does it" is right up there with "Harvard does it." Unfortunately, Harvard really does do it, as do too many other bastions of science-based…
drorzel | June 6, 2011One of the tabs I opened last week and didn't have time to get to was this Clastic Detritus post about what it takes to get science stories in the media, which is (quoting Michael Lemonick):
I get it that a stories involving science need a little something extra to make it in a magazine like Time or even near the front pages of a mainstream newspaper. Or, put another way:
It should be surprising, important -- or weird and fun, failing the important.
I get it that the average non-scientist out there isn't going to take the time to read an article about "ordinary" science. I get it. Our…
pharyngula | June 5, 2011It's the Holotypic Occlupanid Research Group. "Occlupanid", in case you weren't familiar with the lingo, is the taxonomic term for bread ties, those little plastic clips used to close up plastic bread sacks. There is more than you ever wanted to know about bread ties at that link.
It's actually rather thought provoking: it's an entire classification scheme for a trivial industrial widget.
pharyngula | June 4, 2011Here's his latest.
Also remember, Aron Ra, DPR Jones, Lone Frank, and I will be on the Magic Sandwich Show tomorrow at 8pm GMT, live from Dublin. Tune in!
drorzel | June 3, 2011It's been a long and brutally busy week here, so I really ought to just take a day off from blogging. But there's a new paper in Science on quantum physics that's just too good to pass up, so here's a ReasearchBlogging post to close out the week.
Aw, c'mon, dude, I'm tired. What's so cool about this paper that it can't wait until next week? Well, the title kind of says it all: they measured the average trajectories of single photons passing through a double-slit apparatus. By making lots of repeated weak measurements at different positions behind the slits, they could reconstruct the average…
drorzel | June 2, 2011This is the alst week of the academic term here, so I've been crazy busy, which is my excuse for letting things slip. I did want to get back to something raised in the comments to the comments to the Born rule post. It's kind of gotten buried in a bunch of other stuff, so I'll promote it to a full post rather than a comment.
The key exchange starts with Matt Leifer at #6:
The argument is about why we should use the usual methods of statistics in a many-worlds scenario, e.g. counting relative frequencies to estimate what probabilities we should assign in the future. It is not simply about…
drorzel | June 2, 2011(This post is part of the new round of interviews of non-academic scientists, giving the responses of George Farrants, a freelance translator (and occasional marathon runner, as seen in the picture). The goal is to provide some additional information for science students thinking about their fiuture careers, describing options beyond the assumed default Ph.D.--post-doc--academic-job track.)
1) What is your non-academic job?
I work as a freelance translator from Swedish and Norwegian into English. I try to specialise in scientific, medical and technical texts, but I accept texts from many…
drorzel | June 2, 2011This morning's Links Dump included a post from Mad Mike and an entire blog on improving academic posters. For those not in the sciences, one of the traditional means of communicating research results is at a poster session where tens to hundreds of researcher each prepare a poster (usually 3'x5' or thereabouts) about their project, hang them up, then stand by them to answer questions.
Mike and the Better Posters bloggers have some very good tips on graphic design for the benefit of the scientists "gamely trying to not look depressed at the complete lack of attention their posters are…
oracknows | June 1, 2011Even though I was only in junior high and high school back in the 1970s, because I was already turning into a science geek I remember Senator William Proxmire (D-WI). In particular, I remember his Golden Fleece awards. These were "awards" designed to highlight what he saw as wasteful government spending, targeting, for instance, the use of taxpayer funds to fly over 1,000 officers to a reunion of the Tailhook Association or financing the construction of an 800- foot limestone replica of the Great Wall of China in Bedford, Indiana. Others, although they sounded on the surface to be wasteful,…
drorzel | June 1, 2011In just under two weeks, I'll be giving an invited talk at DAMOP (that is, the annual meeting of the Division of Atomic, Molecular, and Optical Physics of the American Physical Society) that is intended to serve as an introduction to the meeting for new students or physicists from other fields. My plan is to pick 3-4 areas and give a quick summary of those subfields, highlgihting a few invited talks in that area from the full program.
My background is in cold-atom physics, so obviously I have a good idea of what's what in those areas, and I follow things like quantum information and precision…
drorzel | June 1, 2011One of the interesting things about reading David Kaiser's How the Hippies Saved Physics was that it paints a very different picture of physics in the mid-1970's than what you usually see. Kaiser describes it as a very dark time for young physicists, career-wise. He doesn't go all that deeply into the facts and figures in the book, but there's plenty of quantitative evidence for this. The claim of the book is that this created a situation in which many younger physicists were pushed to the margins, and thus began to work on marginal topics like quantum foundations, which thus began be be…
drorzel | June 1, 2011(This post is part of the new round of interviews of non-academic scientists, giving the responses of Jennifer Saam, who translates between different departments at a medical diagnostic laboratory. The goal is to provide some additional information for science students thinking about their fiuture careers, describing options beyond the assumed default Ph.D.--post-doc--academic-job track.)
1) What is your non-academic job?
I am a medical science liaison at a medical diagnostic laboratory.
I work in the medical services department and this department maintains the scientific integrity for the…
oracknows | May 31, 2011I've caught some flak before over things I've written about the almost certainly nonexistent link between cell phones and cancer. Actually, it's not the kind of flak you probably think, unless you've been a long time reader and remember the relevant posts. You'd think it would be believers attacking the mean old skeptic for denying a link between cell phone radiation and cancer, thus making me (obviously) a shill for big telecom. Actually, it was flak from one physicist and at least a couple of skeptics, who didn't like that I actually left open the small possibility that it could be possible…
drorzel | May 31, 2011A bunch of people I follow on social media were buzzing about this blog post yesterday, taking Jonah Lerher to task for "getting spun" in researching and writing this column in the Wall Street Journal about this paper on the "wisdom of crowds" effect. The effect in question is a staple of pop psychology these days, and claims that an aggregate of many guesses by people with little or no information will often turn out to be a very reasonable estimate of the true value. The new paper aims to show the influence of social effects, and in particular, that providing people with information about…
