Prof Cox got me interested in physics again. I now have a much better understanding on quantum mechanics and Einstein's theories of relativity because I became interested enough to read more books. Anyone who can make physics more interesting and understandable is someone we need more of on TV.
PS I also really like The Infinite Monkey Cage on Radio 4.
Much better in Monkey Cage and on other discussion shows IMO than straight presenting, which is a little over earnest.
But then he's appealing to those not so interested in science, I'm not in the target demographic...
