    Updated: 2009-08-20 23:24:06
    Sen. Al Franken showed a serious interest in particle physics when he toured the Soudan Mine 2500-feet underground in Minnesota last week. The former comedy writer and talk show host was full of earnest questions about the physics behind the mine's current operating experiments: a dark matter detector called the Cryogenic Dark Matter Search, or CDMS II; and a high-energy neutrino detector called the Main Injector Neutrino Oscillation Search, or MINOS.

Apparently it is very good this year. So wander out when it is dark enough and see what you can see. Look toward Perseus, of course. More information here, from the Meteor blog, and the ever-excellent Stardate site gives you some directions (or look here). In a big city like Los Angeles?

Before you say, "I've heard that before," listen up--this isn't the Large Hadron Rap, the surprise sensation that's logged more than 5 million views on YouTube. There's a brand-new riff on particle physics, created by rapper and science enthusiast Funky49, a.k.a. Steven Rush. It's called the Fermilab Rap, or "Particle Business," and it's a tad slicker and a touch edgier than any physics rap you've heard before.

  • LHC Update

    Updated: 2009-08-06 06:37:08
    Dennis Overbye wrote a nice summary article in the New York Times about the current status of the delays to the Large Hadron Colllider’s (LHC’s) re-opening. (Photo left by Valerio Mezzanotti for NYT) The issue is very frustrating, overall, even though one knows that delays like this can happen (and ought to be expected to happen) if you’ve built the largest and most complicated machine ever. I (and many colleagues) have in some sense waited for the LHC almost my entire professional career, and last Summer/Fall it seemed so close to finally starting to give us physics, only to have the failure happen, and set it all back. That’s life, of course. These things happen. I’ve a great deal of faith in the [...]
