Do you listen to the CERN LHC podcasts? They can be good. Every now and again, there’s a visitor there, and Brian Cox interviews them on site at the Large Hadron Collider. (Search archives for LHC or see links to lots of posts on it below, such as this one.) The most recent visit is by Phil Plait, aka the Bad Astronomer. They chat together about various aspects of the science to be done at the (soon to be switched on!) LHC, research in basic science in general, the scare-mongering business about the black holes destroying the earth (see here and here), conspiracy theories, and – of course – the general awesomeness of the machine itself. (Go to iTunes and subscribe to the podcast. Search for CERN – Large Hadron Collider.)
Phil raves about his visit in a recent post on the Bad Astronomy Blog here.
