In the reader request thread, Brad asks about superconductors: Why is a room temperature superconductor so hard? Why do things have to be cold for there to be no resistance (I can guess, but my knowledge of super conductors consists of the words “Cooper pairs” which does not get me very far.) Since next year… Continue reading How Do Superconductors Work?

What’s a Topological Insulator?
Yesterday’s post about how nobody cares about condensed matter physics produced a surprising number of comments of the form “I was really hoping you would post about topological insulators,” which surprised me a bit. Anyway, since people asked for it, I’ll give it a shot. The important caveats here are that 1) this isn’t my… Continue reading What’s a Topological Insulator?
Holy Grails of Science
With the rumors of a Higgs Boson detected at Fermilab now getting the sort of official denial that in politics would mean the rumors were about to be confirmed in spectacular fashion, it’s looking like we’ll have to wait a little while longer before the next “Holy Grail” of physics gets discovered. Strictly speaking, the… Continue reading Holy Grails of Science
Uncomfortable Question: My Bad?
Next in line of questions from readers, we have tbell with: Since science is a self-correcting process (maybe only at a statistical level, not necessarily an individual level), it would be cool if you would relate the last time you were seriously wrong about some aspect of science or research, and how you altered your… Continue reading Uncomfortable Question: My Bad?
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
Through the Wormhole
The Science Channel debuted a new show last night, Through the Wormhole with Morgan Freeman, with the premier apparently designed by committee to piss off as many Internet types as possible. The overall theme was “Is there a creator?” and it featured physicist-turned-Anglican-priest John Polkinghorne talking about fine-tuning but no atheist rebuttal. It spent a… Continue reading Through the Wormhole
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
Summertime Thermodynamics: Car Windows Open or Closed?
This may be a job for the MythBusters, but I’ll throw this out as a puzzle for interested blog readers. I don’t know the answer to this (though it wouldn’t be all that hard to determine experimentally), I just think it’s sort of interesting. There’s a poll at the bottom of this post, but it… Continue reading Summertime Thermodynamics: Car Windows Open or Closed?
Anatomy of a Conference: DAMOP Day 2– The Rise of Precision Measurement
Since I sort of implied a series in the previous post, and I have no better ideas, here’s a look at Thursday’s DAMOP program:
My Wednesday at DAMOP
I was pretty sedentary on Wednesday, going to only two sessions, and staying for most of the talks in each. I spent most of the initial prize session getting my bearings in the conference areas, and talking to people I know from my NIST days. In the 10:30 block, I went to the session on… Continue reading My Wednesday at DAMOP
