Physics Blogging Round-Up: ARPES, Optics, Band Gaps, Radiation Pressure, Home Science, and Catastrophe

SteelyKid's digital microscope looking at hair on a Lego frame.

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… Continue reading Physics Blogging Round-Up: ARPES, Optics, Band Gaps, Radiation Pressure, Home Science, and Catastrophe

Physics Blogging Round-Up: Mostly March Meeting

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… Continue reading Physics Blogging Round-Up: Mostly March Meeting

What Should I See At The March Meeting?

The APS March Meeting web page

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… Continue reading What Should I See At The March Meeting?

The Schrödinger Sessions II: More Science for More Science Fiction

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… Continue reading The Schrödinger Sessions II: More Science for More Science Fiction

What To Tell Your Dog About Quantum Physics: The Movie

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… Continue reading What To Tell Your Dog About Quantum Physics: The Movie

Physics Blogging Round-Up: Jocks, Lasers, LIGO, Admissions, Nano-Movies, and Philosophy

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… Continue reading Physics Blogging Round-Up: Jocks, Lasers, LIGO, Admissions, Nano-Movies, and Philosophy

Attempted Mpemba Effect

Materials for an attempt to observe the 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… Continue reading Attempted Mpemba Effect

165/366: Wintry Science

Starting condition for a science experiment.

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… Continue reading 165/366: Wintry Science

160/366: Nice Crowd

The audience for my Science Series talk last night at Jefferson Lab.

I did bring my good camera with me to Newport News, and took it on the tour of Jefferson Lab yesterday, but despite the existence of DSLR pics, you’re getting a cell-phone snap for the photo of the day: That’s the audience about 10-15 minutes before my talk last night, so it was a good… Continue reading 160/366: Nice Crowd
