Kevin Drum checks in with the latest from the class wars: In the middle of a rant about healthcare reform and the compromise over the Cadillac tax, one of Andrew Sullivan’s readers says this: The idea that public employees make less than those in the private sector is a myth that needs to die. Most… Continue reading When Oldsmobiles Turn Into Cadillacs

Physics Buzz: A Star Class is Born “Scientists have proposed that there is a new, exotic type of star living in our universe that we haven’t seen yet. The so-called “electroweak stars”, if they exist, will be difficult to detect because they mostly emit neutrino’s – subatomic particles which, for the most part, don’t interact… Continue reading Links for 2010-01-26
Perfect for Readers Who Already Have Eaten Cheese in Physics
The great thing about using Google to vanity search for articles about How to Teach Physics to Your Dog, or at least one of the great things about it, is that it’s world-wide. Thus, this Dutch roundup of new books, which includes mine. This is what they have to say: Een erg geestig boek is… Continue reading Perfect for Readers Who Already Have Eaten Cheese in Physics
Single-Photon Cooling: Making Maxwell’s Demon
As mentioned previously, I’ve been reading Sean Carroll’s Wheel arrow of time book, which necessarily includes a good bit of discussion of “Maxwell’s Demon,” a thought experiment famously proposed by James Clerk Maxwell as something that would allow you to cool a gas without obviously increasing entropy. The “demon” mans a trapdoor between a sample… Continue reading Single-Photon Cooling: Making Maxwell’s Demon
Trapping Ions With Light
There was a flurry of stories last week about an arxiv preprint on optical trapping of an ion. Somewhat surprisingly for an arxiv-only paper, it got a write-up in Physics World. While I generally like Physics World, I have to take issue with their description of why this is interesting: In the past, the trapping… Continue reading Trapping Ions With Light
Fifty Years of Solutions Finding Problems
2010 marks the 50th anniversary of the invention of the laser. To mark the occasion, the American Physical society has launched LaserFest, which will involve a large number of public events over the next year. The website includes a bunch of cool things explaining the physics of lasers, and a timeline of laser history with… Continue reading Fifty Years of Solutions Finding Problems

The American Spectator : Osama bin Elvis “Seven years after Osama bin Laden’s last verifiable appearance among the living, there is more evidence for Elvis’s presence among us than for his. Hence there is reason to ask whether the paradigm of Osama bin Laden as terrorism’s deus ex machina and of al Qaeda as the… Continue reading Links for 2010-01-25
How to Teach Physics to Your Dog: All the News That’s Fit to Keep Off the Web Page
A few weeks back, I spoke on the phone with a freelance writer who was doing a piece for the Albany Times Union. She was putting together a joint article on How to Teach Physics to Your Dog and the Atomville book put together by Jill Linz and Cindy Schwarz (at Skidmore and Vassar, respectively).… Continue reading How to Teach Physics to Your Dog: All the News That’s Fit to Keep Off the Web Page
More Entropy, Less Spanking
I’m currently a bit less than halfway through Sean Carroll’s From Eternity to Here, which has leaped to the top of the literary inbox because I’ll be hosting a Book Salon at firedoglake next Saturday evening. If you want to see how my limited typing skills work in a live chat setting, be sure to… Continue reading More Entropy, Less Spanking
All Creatures Great and Small…
… are welcome in the DogPhysics Pet Gallery. Even aquatic ones: We’ve currently got seventeen dogs, six cats, two horses, a lizard, and these fish. If you’ve got a pet, of whatever species, and a copy of How to Teach Physics to Your Dog, take a picture of the one with the other, and send… Continue reading All Creatures Great and Small…
