(This post is part of the new round of interviews of non-academic scientists, giving the responses of Will Hendrick, who worked as a lab tech before returning to school. (This may seem like an odd inclusion, but there are people who do this sort of thing forever, so I think it’s valid.) The goal is… Continue reading PNAS: Will Hendrick, (Former) Biomedical Technician

Lessons in Applied Data Archaeology
I’m teaching our upper-level lab course this term, where I do a two-part experiment on laser spectroscopy. The first part is to calibrate the free spectral range of a homemade Fabry-Perot interferometer, and the second part is to use that Fabry-Perot as a frequency marker to calibrate a diode laser scan across the rubidium hyperfine… Continue reading Lessons in Applied Data Archaeology
PNAS: Amy Young, Saponifier
(This post is part of the new round of interviews of non-academic scientists, giving the responses of Amy Young, who runs her own soap-making business. 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?… Continue reading PNAS: Amy Young, Saponifier
When Aliens Attack
As I have admitted previously, I have a fondness for tv shows about UFO’s, the loonier the better. So, when I learned that there was a show called When Aliens Attack airing last night on the National Geographic channel, I was all over that. I’m happy to report that it did not disappoint– it brought… Continue reading When Aliens Attack
Return of the Project for Non-Academic Science
In keeping with this week’s unofficial theme of wibbling about academia, there’s an article at The Nation about the evils of graduate school that’s prompted some discussion. Sean says more or less what I would, though maybe a little more nicely than I would. I wouldn’t bother to comment further, except this spurred Sean to… Continue reading Return of the Project for Non-Academic Science
Filtering Isn’t the Problem
Via Twitter, Daniel Lemire has a mini-manifesto advocating “social media” alternatives for academic publishing, citing “disastrous consequences” of the “filter-then-publish” model in use by traditional journals. The problem is, as with most such things, I’m not convinced that social media style publication really fixes all these problems. For example, one of his points is: The… Continue reading Filtering Isn’t the Problem
Idle Historical Question: Why p?
Today’s lecture topic was position-space and momentum-space representations of state vectors in quantum mechanics, which once again brought up one of the eternal questions in physics: Why do we use the symbol p to represent momentum? I did Google this, but none of the answers looked all that authoritative. And, anyway, I’m sure that the… Continue reading Idle Historical Question: Why p?
How to Teach Physics to Your Dog On TV
Well, on video over the web, anyway… If you look at the Featured Videos on the National Geographic Channel web page, or, hopefully, in the embedded video below: You’ll see a short video clip of a program about quantum physics, that includes me and Emmy among the experts on camera. I’m pretty psyched, though I’m… Continue reading How to Teach Physics to Your Dog On TV
“Supersolids”: The Saga Continues
Several years ago, now, a group at Penn State announced a weird finding in helium at extremely low temperatures and high pressures (which is what you need to make helium solidify): when they made a pendulum out of a cylindrical container with a thin shell of solid He toward the outside edge, twisting about its… Continue reading “Supersolids”: The Saga Continues
Active Engagement Works: “Improved Learning in a Large-Enrollment Physics Class”
Physics is a notoriously difficult and unpopular subject, which is probably why there is a large and active Physics Education Research community within physics departments in the US. This normally generates a lot of material in the Physical Review Special Topics journal, but last week, a PER paper appeared in Science, which is unusual enough… Continue reading Active Engagement Works: “Improved Learning in a Large-Enrollment Physics Class”
