I was aware, and moderately a fan of, Brian Cox from watching the UK show "QI" and a few other interviews. I liked how he explained particle physics concepts and tries to bring these concepts to the masses. It helps he's not bad-looking, either.

But it wasn't until I saw "Professor Brian Cox Enraged Deepak Chopra" that I knew I wanted more. Getting Chopra to tell you to shove something up your ass after you present a fact? Sign. Me. Up.

He and comedian Robin Ince have being presenting world tours for several years, and on Sunday there was one at a local theater. C, gorthx, and I went and, despite our various ailments that evening, we enjoyed it.

The prof talked about the history of the universe, how space and time work, the possibility of life in other galaxies, and black holes. Robin made fun of him and talked about life and science on this planet1. It was a nice mix.

My favorite part was the simulation of a black hole. Interstellar's director wanted to get space as accurate as possible in the movie, and consulted scientists to create a computer model that would generate it. Prof. Cox used it in his show to simulate a black hole and all the warping of space around it. And guess what? It looks like the picture of the supermassive black hole that was recently taken by Event Horizon Telescope. Neat-o!

Oh, and he explained event horizons. I think I understand it. And I hadn't realized water had actually been discovered on Mars.

If any of you listen to Radiolab, you will have heard this already. If you haven't heard the latest episode, and want to be surprised, stop reading. Go listen to it - your mind will be blown. And I'm not using that term in the way that everyone over-uses the word "awesome" now-a-days.

There's a scientist - Lene Vestergaard Hau - at Harvard who has found a way to isolate really slow atoms by ... encouraging the faster atoms, with lasers, to go away. I'm sure there's a much more technical way to say that.  When you shine light though these slow atoms, it slows down to about 15 miles per hour! Yes, you can actually ride a bike faster than this light. 

And then they dropped the fact that she can actually stop light. STOP. LIGHT. Say, if you had a box with these super slow atoms in it, you could shine light into this box, and stop the light inside it.

And then... and then she mentioned that the stopped light leaves an impression on the atoms, which you could then transport somewhere else in said box, and then recreate the light from the impressions on the atoms. What the what the what?!?  So... light, to matter, to light?

AAAAAHHHHHH!

Of course, they're talking about mundane real world applications like more security on the internet, but holycrapsmackers TRANSPORTERS!!!

You can listen and read more about it at Radiolabs "Behind the Scenes" for this segment.
