Brian Cox, showing us the "Wonders of the Solar System" on the Science Channel. He's just really adorable, and I love how excited he gets about stuff. He also reminds me of my RL physicist friend, who is also from Manchester (altho he's more Scottish now; also, less outgoing).
Which is not to say that the new kid has replaced Michio Kaku (TV physicist older gentleman caller?) in my affections; just last week he reminded me of his own brand of cool adorableness when he was talking about the physics of sex in zero G.
Oh, I <3 TV physics.
