It’s one of those days where none of the stuff I probably ought to be writing seems even slightly appealing, so instead I’m going to do something frivolous and morale-boosting, namely think out loud about an imaginary course. Despite being on sabbatical, I do still check my work email, and have caught the edges of…

It’s been a while since I last rounded up physics posts from Forbes, so there’s a good bunch of stuff on this list: — How Do Physicists Know What Electrons Are Doing Inside Matter?: An explanation of Angle-Resolved Photo-Electron Spectroscopy (ARPES), one of the major experimental techniques in condensed matter. I’m trying to figure out…

I was at the APS March Meeting last week, because I needed tp give a talk reporting on the Schrödinger Sessions. But as long as I was going to be there anyway, I figured I should check out the huge range of talks on areas of physics that aren’t my normal thing– in fact, I…

I’m going to be at the March Meeting of the American Physical Society in Baltimore next week. This is the largest physics meeting of the year, with an emphasis on condensed matter physics (which is actually the largest single area of study within physics, though media overemphasis on particle physics and astrophysics might lead you…

As you probably already know, last year we ran a workshop at the Joint Quantum Institute for science-fiction writers who would like to learn more about quantum physics. The workshop was a lot of fun from the speaker/oragnizer side, and very well received by last year’s writers, so we’re doing it again: The Schrödinger Sessions…

A few weeks ago, I traveled down to Jefferson Lab in southern Virginia to give a talk for their Science Series of public lectures. They recorded the talk, and have done a very nice job of editing together the video, which you can see at that link, or right here: It’s a bit under an…

It’s been a few weeks since my last summary of physics posts I’ve been doing at Forbes, so here’s the latest eclectic collection: — Football Physics And the Myth Of The Dumb Jock: In honor of the Super Bowl, repeating the argument from Eureka that athletes are not, in fact, dumb jocks, but excellent scientific…

March Appearances

I’ve been really, really bad about using this blog to promote stuff I have coming up, but I’ll be doing two public-ish appearances in the month of March, and I probably ought to announce those here: 1) Next week, on Wednesday, March 2, I’ll be giving the Physics Colloquium at the University of Illinois, on…

Attempted Mpemba Effect

One of my favorite modern tales of scientific discovery is the Mpemba Effect, named after Erasto Mpemba, a schoolboy in Tanzania who noticed while making ice cream that hot mix put in the freezer solidified faster than cold. This counter-intuitive result has been replicated a bunch of times, and physicists and chemists continue to debate…

165/366: Wintry Science

It was bitterly cold over the weekend here in the Northeast, with daytime high temepratures in the single digits Fahrenheit. This has little to recommend it in terms of, you know, leaving the house, but it did provide an opportunity to try some SCIENCE! Unfortunately, I left the notepad with the data (such as it…
