I no longer remember the context, but the Gravity Probe B experiment came up in discussion around the department last week, and nobody could really remember what the status of it was. It came up again during the “Physics: What We Don’t Understand” panel Saturday morning, where Geoff Landis was able to supply a few… Continue reading Gravity Probe B Is in the Air

Quantum Physics for Dogs: Many Worlds, Many Treats?
On Saturday at Boskone, I gave a talk on the Many-Worlds Interpretation of QM. This was held up a bit by waiting for the projector to arrive (I was busy enough with other stuff that I didn’t notice that I hadn’t received confirmation of my request for a projector until late Thursday night, so this… Continue reading Quantum Physics for Dogs: Many Worlds, Many Treats?
Happy News Open Thread
I’ve been a Grumpy Blogger this week, what with one thing and another (some of my general malaise has finally resolved into a cold, which I suspect explains a lot). I’m headed to Boskone for the weekend, though, so let’s end the week on a positive note. I’m declaring this a Happy News Open Thread:… Continue reading Happy News Open Thread
Best Physical Science Writing of 2008?
I didn’t expect the post griping about the Best American Science Writing anthology to generate as much discussion as it did. Shows what I know. In comments, “bsci” made a good suggestion: Instead of complaining about this volume, I’d love it if you and your readers made a list of the best physics writing in… Continue reading Best Physical Science Writing of 2008?
Heads Talking About Quantum History
I’m running a little behind this week, but I wouldn’t want this week’s Science Saturday bloggingheads to slip by without a mention. It’s a conversation between George Johnson and Louisa Gilder about The Age of Entanglement, which I liked quite a bit: The conversation is primarily about her book, the story it tells, and how… Continue reading Heads Talking About Quantum History
Essential Skills and Experiences?
Like a lot of physics departments, we offer an upper-level lab class, aimed at juniors and seniors. There are a lot of ways to approach this sort of course, but one sensible way to think about it is in terms of giving students essential skills and experiences. That is, i’s a course in which they… Continue reading Essential Skills and Experiences?
Physics Gets No Respect
Kind of a belated gripe, but something I was reminded of today that I forgot to blog when I first noticed it. I griped last year about the fomulaic nature of the “Best Science Writing” anthology, but I had no idea that the 2008 version would be worse. OK, I haven’t read it, but I… Continue reading Physics Gets No Respect
Science and Sociology of Dark Matter
There’s a new paper from the PAMELA dark matter search out that’s written up in Physics, including a link to a free version of the PDF. This paper is considerably less dramatic than one that appeared last year, leading Physics World to suggest that they’re backing off the earlier claim. What’s the deal? Sean Carroll… Continue reading Science and Sociology of Dark Matter
The Swashbuckling Physicist’s Guide to Complex Numbers
Having mentioned this a few times in course reports, I thought I’d throw out a link to my lecture notes (PDF) on complex numbers. This is the one-class whirlwind review of complex numbers from defining i to Euler’s theorem about complex exponentials. To answer a slightly incredulous question from a commenter, this is necessary because… Continue reading The Swashbuckling Physicist’s Guide to Complex Numbers
Lab Reports: Threat or Menace?
I got the last round of line edits on the book-in-progress Monday night after work, but I haven’t had a chance to do more than leaf through the pages. This is mostly because I had lab reports to grade– the second written report is due Sunday, and I needed to get comments back to the… Continue reading Lab Reports: Threat or Menace?
