An experiment in Germany has generated a good deal of publicity by dropping their Bose-Einstein Cendensate (BEC) apparatus from a 146 meter tower. This wasn’t an act of frustration by an enraged graduate student (anybody who has worked with BEC has probably fantasized about throwing at least part of their apparatus down a deep hole),… Continue reading Dropping Bose Condensates for Fun and Science

Cathedral-Building in Science
Tommaso Dorigo has an interesting post spinning off a description of the Hidden Dimensions program at the World Science Festival (don’t bother with the comments to Tommaso’s post, though). He quotes a bit in which Brian Greene and Shamit Kachru both admitted that they don’t expect to see experimental evidence of extra dimensions in their… Continue reading Cathedral-Building in Science
Exploring Hidden Dimensions at the World Science Festival
Since I was going to be down here anyway to sign books at the World Science Festival Street Fair, Kate and I decided to catch one of the Saturday events at the Festival. It was hard to choose, but we opted for the program on Hidden Dimensions: Exploring Hyperspace (Live coverage was here, but the… Continue reading Exploring Hidden Dimensions at the World Science Festival
Evil Squirrels from Extra Dimensions
It’s been a very long day, so I’m lying on the couch watching “Pardon the Interruption” on ESPN. They’re having a boring conversation about baseball, and I’m just drifting off into a pleasant doze when: “Fear! Fire! Foes! Awake! Fear! Fire! Foes! Awake!“ I jolt awake. “What are you barking at?!?” I yell at the… Continue reading Evil Squirrels from Extra Dimensions
Why Do We Have Stuff? Hints from Fermilab
There’s a Dennis Overbye article in the Times today with the Web headline “From Fermilab, a New Clue to Explain Human Existence?” which I like to think of as a back-handed tribute to the person who linked to an interview with Sean Carroll by calling him “The cosmologist, not the scientist.” This is the secret… Continue reading Why Do We Have Stuff? Hints from Fermilab
Inconstant Constants: “Probing fundamental constant evolution with redshifted conjugate-satellite OH lines”
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 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
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
Conference Organizers Should Not Live in Caves
A sad and sordid story from the Times Higher Education following the rescinding of invitations to a conference on quantum foundations: Details of the conference in August for experts in quantum mechanics sounded idyllic. Participants were due to discuss “de Broglie-Bohm theory and beyond” in the Towler Institute, which is housed in a 16th-century monastery… Continue reading Conference Organizers Should Not Live in Caves
Hawking on Aliens: Not as Silly as You’d Like to Think
I’m a little surprised at the vehemence of some of the negative reactions to Stephen Hawking’s comments about aliens. Not so much in blogdom– Ethan’s response is pretty reasonable, for example– but there was a flurry of Twitter traffic yesterday of the form “Where does Stephen Hawking get off pontificating about aliens?” which strikes me… Continue reading Hawking on Aliens: Not as Silly as You’d Like to Think
