Professor Brian Cox demonstrates why atoms are empty

Did you watch "A Night With The Stars" on BBC2 last night?

Professor Brian Cox lectured a celebrity audience about some of the most challenging concepts in physics from the lecture theatre of the Royal Institution of Great Britain.

Here's a clip from the show:
The comedian Simon Pegg and physicist Jim Al-Khalili help him explain standing waves in a demonstration to show why atoms are so large and empty.




It was a brilliant show! If you missed it, be sure to catch in on iPlayer.

Prime Minister's Questions: 14 December 2011

Watch today's Prime Minister's Questions - the last prime minister's questions of 2011:



Prime Minister, David Cameron, answered questions from MPs in the House of Commons on subjects including the Royal Bank of Scotland, unemployment and youth employment, the recent EU Council meeting and citizenship education.

The best line from today's PMQs was from David Cameron in response to Ed Milliband remarking about the tension between the Prime Minister and his deputy, Nick Clegg:

No one in this house is going to be surprised that Conservatives and Liberal Democrats don't always agree about Europe. But let me reassure him he shouldn't believe everything he reads in the papers. It's not that bad. It's not like we're brothers or anything.

It was certainly a rousing session. Cameron was on fire (doing really well). It has to be said that the Labour leader, Ed Milliband, looked very weak, indeed.
