For her birthday, SteelyKid got a “Butterfly Keeper” set, which is basically a big mesh cylinder maybe two feet high and a foot in diameter. It came with a coupon for free live caterpillars for “Painted Lady” butterflies, which we duly sent away for. These came in a plastic cup full of caterpillar food, with… Continue reading Help Me, Internet Biologists, You’re My Only Hope

The “Ballistic” Story
Last week, in the post about fermion conduction, I left a reference hanging: There’s nothing physically blocking the atoms from flying right through the channel– in fact, an atom that enters the channel will always exit the other side without slowing down along the way. This is termed “ballistic,” a term that will always have… Continue reading The “Ballistic” Story
Simulating Wires with Atoms and Light: “Conduction of Ultracold Fermions Through a Mesoscopic Channel”
So, it’s been a while, but let’s see if we can’t hit the ground running with a good physics post. There have been a few notable physics events since I went on hiatus, but for a return to physics ResearchBlogging, we’ll go with something near and dear to my heart, ultracold atoms. Specifically, this Science… Continue reading Simulating Wires with Atoms and Light: “Conduction of Ultracold Fermions Through a Mesoscopic Channel”
Higgs Rumors Are the Price of Success
In which celebrity culture comes to particle physics. ———— It’s been about six months since we had a big flurry of Higgs Boson stories, and as enjoyable as the relative quiet has been, it means we’re due for another run. And, predictably enough, the usual suspects are stoking speculation about what, exactly, will be officially… Continue reading Higgs Rumors Are the Price of Success
The Perfection of Bay Area Dogphysics
Last night, as I was flying in to San Francisco, Matt Cain pitched the first perfect game in Giants history. Now, a casual observer might think these events were unrelated, but to ancient alien theorists, the connection between them could not be more obvious. Thus, you should come to Kepler’s Books in Menlo Park this… Continue reading The Perfection of Bay Area Dogphysics
How Did the arXiv Succeed?
In which we look again at the question of why, despite the image of physicists as arrogant bastards, biologists turn out to be much less collegial than physicists. ———— While I was away from the blog, there was a spate of discussion of science outreach and demands on faculty time, my feelings about which are… Continue reading How Did the arXiv Succeed?
Relativity for Bay Area Dogs, Among Others
Two How to Teach Relativity to Your Dog items: First and foremost, I’ll be appearing at Kepler’s Books in Menlo Park, CA, this Thursday, June 14 at 7:00pm. I’ll probably read a bit of the book, so if you’ve ever wanted to hear me do the silly dog voice live, here’s your chance. Provided, of… Continue reading Relativity for Bay Area Dogs, Among Others
Single Photons Are Still Photons: “Wave-particle dualism and complementarity unraveled by a different mode”
In which we do a little ResearchBlogging, taking a look at a slightly confusing paper putting a new twist on the double-slit experiment. ———— I’m off to California this afternoon, spending the rest of the week at DAMOP in Pasadena (not presenting this year, just hanging out to see the coolest new stuff in Atomic,… Continue reading Single Photons Are Still Photons: “Wave-particle dualism and complementarity unraveled by a different mode”
Green Speckled Frogs
In which we look at the very latest in amphibian science. ———— The embedded video shows one Prof. S. Kid describing her latest observations in detail. It’s a very comprehensive study.
Excellent Approximations and Lying to Children
In which I talk about the common complaint that we teach students physics that “isn’t true,” and the limits on that statement. ———— Frequent commenter Ron sent me an email pointing to this post by David Reed on “What we “know” that t’aint so…. and insist on teaching to kids!”: he science we teach is… Continue reading Excellent Approximations and Lying to Children
