Via Jennifer Ouellette on Twitter, I ran across a Discovery News story touting a recent arxiv preprint claiming to see variation in the fine-structure constant. It’s a basically OK story, but garbles a few details, so I thought it would be worth giving it the ResearchBlogging treatment, in the now-traditional Q&A format. What did they… Continue reading Inconstant Constants: “Probing fundamental constant evolution with redshifted conjugate-satellite OH lines”

The Matchbox That Ate a Forty-Ton Truck by Marcus Chown
I should note up front that I’m kind of jealous of Marcus Chown regarding this book. Subtitled “What Everyday Things Tell Us About the Universe,” The Matchbox That Ate a Forty-Ton Truck is a book that uses trivial everyday observations– the fact that you don’t fall through the floor, the fact that the sky is… Continue reading The Matchbox That Ate a Forty-Ton Truck by Marcus Chown
The Problem of (Quantum) Moderation: On Many Worlds
I’ve written before about the problem of having in-between views on controversial subjects in blogdom. This is something that also comes up in Jessica’s excellent entry on online culture, and has been scientifically demonstrated in political contexts. I’m somewhat bemused, then, to see the same thing happen in a physics context. A while back, I… Continue reading The Problem of (Quantum) Moderation: On Many Worlds
Ancient Aliens: Performance Art or Government Disinformation?
One of my many character weaknesses is a fondness for the kooky UFO programs run on the History Channel and other educational cable networks. The nuttier the better– there’s something about the credulity and self-delusion displayed by the “researchers” they trot out that I find really hilarious. I have to say, though, that they’ve outdone… Continue reading Ancient Aliens: Performance Art or Government Disinformation?
The Problem of “Theory”
When I was writing about the seemingly contradictory meanings of “adiabatic” the other day, I almost gave “theory” as an example of a word with nearly opposite meanings. After all, as anyone who has even glanced at the evolution-creation “debate” has heard, a “Theory” in science is something more exalted than a mere guess– it’s… Continue reading The Problem of “Theory”
The Past and Future of the Laser
While it’s not aprt of the official LaserFest package of stuff, Physics World is marking the 50th anniversary of the laser with a couple of really nice pieces on lasers in science and popular culture: Where next for the laser interviews six laser experts– Claire Max of UCSC, Bill Phillips of NIST, Steven Block of… Continue reading The Past and Future of the Laser
Academic Poll: Talk or Poster?
The Steinmetz Symposium is today at Union, as mentioned in yesterday’s silly poll about fears (I love the fact that “Wavefunction Collapse” leads “Monsters from the Id” by one vote at the time of this writing– my readers are awesome). As a more serious follow-up, there were two presentation options offered to the students, and… Continue reading Academic Poll: Talk or Poster?
Through a (Noble) Gas, Darkly
There’s a minor kerfuffle at the moment over the XENON experiment’s early data (arxiv paper) which did not detect any dark matter in 11 days of data acquisition. This conflicts with earlier claims by the DAMA experiment and recent maybe-kinda-sorta detections by the CoGeNT and CDMA experiments. As a result, a couple of members of… Continue reading Through a (Noble) Gas, Darkly
Help Me Guide Teachers
My publisher would like to include a Teacher’s Guide with the paperback edition of How to Teach Physics to Your Dog. which means that, well, I need to put together a Teacher’s Guide for How to Teach Physics to Your Dog. The problem is, I’m not exactly sure what should go in that sort of… Continue reading Help Me Guide Teachers
I Do Not Think “Adiabatic” Means What You Think It Means
Over at the Virtuosi, there’s a nice discussion of the physics of letting air out of tires. Jesse opens the explanation with: Have you ever noticed how when you let air out of a bike tire (or, I suppose, a car tire) it feels rather cold? Today we’re going to explore why that is, and… Continue reading I Do Not Think “Adiabatic” Means What You Think It Means
