I had meant to post something or another yesterday, after we got back, but, well, I was still in vacation mode, and didn’t get around to it. I also didn’t queue up anything for today, thinking that I would write something last night, but I didn’t feel like doing that, either. You may get another… Continue reading Final DonorsChoose Notes
Classic Edition: Video Killed the Rhetoric Star
Poking through the archives to find some old physics posts to fill space while I’m away from the keyboard, I realize that back in 2002, I wrote a lot more about politics than I do now.This is largely because most of what I wrote about politics back then makes me cringe now. And, in fact,… Continue reading Classic Edition: Video Killed the Rhetoric Star
Classic Edition: Clever Tricks and Cooling
I’m going to be away from the computer for the long weekend, but I don’t want to have the site go completely dark, even over a weekend, so I’m going to schedule a few posts from the archives to show up while I’m away. Everyone else seems to be doing it (and pushing my posts… Continue reading Classic Edition: Clever Tricks and Cooling
Classic Edition: Not Just Air Conditioning the Laser Lab
I’m going to be away from the computer for the long weekend, but I don’t want to have the site go completely dark, even over a weekend, so I’m going to schedule a few posts from the archives to show up while I’m away.

Brother, Can You Spare Four Dollars?
As you have no doubt seen elsewhere on ScienceBlogs, the great DonorsChoose blog challenge ends tomorrow. I won’t actually be here to do a final post on the subject, so this is the last prodding you’ll get from me. As of this morning, the Uncertain Principles challenge entry stands at $996.02, according to the leader… Continue reading Brother, Can You Spare Four Dollars?
World Cup Dog-Blogging
The great thing about soccer is that even pets can get in on the game: Here, Emmy shows off her ability to bat things around on the floor, in honor of the Germany-Argentina game coming up today. The toy in question is a Buster Cube, which we heartily endorse– it’s a plastic cube with a… Continue reading World Cup Dog-Blogging
How Do You Judge an Interpretation?
Matt Leifer, whose blog I hadn’t previously encountered, has a long and fascinating post on evaluation criteria for quantum interpretations. “Interpretation” here means the stuff of countless “Isn’t Quantum Mechanics weird?” books– Copenhagen, Many-Worlds, Bohmian hidden variable theories, all that stuff. These are the “meta-theories” that are used to explain how you get from all… Continue reading How Do You Judge an Interpretation?
Fun With Diode Lasers
I ended the previous laser post by noting that diode lasers need some additional wavelength selection to be done in order to be useful as light sources for spectroscopy experiments. In their natural state, they tend to emit light over a broader range of wavelengths than is really ideal, and we’d like to narrow that… Continue reading Fun With Diode Lasers
So, CERN Has a Particle Accelerator?
A little while back, JoAnne at Cosmic Variance reported on the status of the Large Hadron Collider (LHC), the giant next-generation accelerator that is the cover story for the current print issue of Seed. Particle experimentalist Gordon Watts reports in with some more technical details about the delay in the proposed turn-on schedule. He’s also… Continue reading So, CERN Has a Particle Accelerator?
