Wormholes, Portals and Extra Footage

After a few viewer requests, we decided to do a Sixty Symbols video about the new game Portal 2.

It's a game with a lot of science content.

Physicist Professor Phil Moriarty agreed to buy the game and play it - then give his verdict.

Fellow Professor Ed Copeland (a particle physicist and cosmologist) hadn't played the game, but agreed to chip in because he knew a bit about wormholes!



As you can see from the video, I made a few cuts (and made a few jokes about it at Phil's expense). So it was only fair I also upload some of the extra footage.

Here's more from Phil.



And more from Ed.
