Very interesting. Simon Pegg's contributions make this wonderfull *comedy as well.

Adding video to channels (Comedy) - requested by hpqp.

Dude Famous audience members...so far I've seen Jonathan Ross, Charlie Brooker with his wife Konnie Huq.

I thought some of you might like this video.

that's a fantastic explanation, now I'll just need a couple of comedian sidekicks so I can explain it to others Any volunteers?

Adding video to channels (British) - requested by Zifnab.

The full program is called A Night with the Stars. It's available on BBC iplayer, and also other "less official" sources if you aren't in the UK.

The full programme was intensely annoying, full of attention-seeking celebrities desperately mugging for laughs and Cox demonstrating a curious difficulty with understanding sarcasm. The science was definitely secondary to the mocking celebrities who were busy pretending to be stupid for the sake of a little camera-time, which prevented the physics from really coming across.

this is cool too:

Improved measurement of the shape of the electron - 2011

briefly

"Here we use cold polar molecules to measure the electron EDM at the highest level of precision reported so far, providing a constraint on any possible new interactions. We obtain de = (−2.4 ± 5.7stat ± 1.5syst) × 10−28e cm, where e is the charge on the electron, which sets a new upper limit of |de| < 10.5 × 10−28e cm with 90 per cent confidence. This result, consistent with zero, indicates that the electron is spherical at this improved level of precision."

I watched this earlier and it's pretty fucking dreadful. Cox's lecture is interesting but this obsession with celebrities again - save it for ITV please.

Peter Snow and his son Dan too, not that we're getting caught up in the celebrity aspect (hasn't Brooker done well for himself, Konnie Huq is yummy!).

Jim Al-Khalili is probably the smartest person there, I've seen a few of his documentaries on the BBC. He's Iraqi I think, and he's nuclear physicist with an Arabic name so he's probably never got on a flight without getting a cavity search before

Jim Al-Khalili's shows are better than Cox's big budget, smiley, standing on a mountain while a helicopter flies around style of pop science programming.

Its just trying to hard to be easily digestible by those disinterested teenagers. I don't really like it either, and I don't think people need a Simon Peg to make science interesting as long as its being presented well, but hey ho, it is what it is.

IS THERE ANYTHING YOU FUCKING LIKE!??! Jesus Christ I thought I was a Cynic. Get the fuck out with your self loathing over critical bullshit you fucking faggot!

Just for a bit of conversation, did any of you catch that he doesn't tell us what holds the "other" end of the spring? He says the nucleus acts like a box. How so? What are the ends of the box?

Elementary my dear Mycroft. (Elementary particles) -Constituent parts of the nucleus manifest as mass & therefore gravity.
Actually I'm not that smart but couldn't resist. Might be some other force at that scale - sift physicists?

The last time I looked, it involved virtual particle that pop in and out of existence (lots of them) and do other unusual things to tether the electron. This is of course known as the electromagnetic force, which is very well known and understood, however understanding just exactly how it works involves very complicated quantum physics which I don't know a lot about. As far as I know these virtual particles create a sort of a photon field with which the electrons interact which in turn gives rise to the electromagnetic wave.

So it's not gravity, the electromagnetic force is much, much stronger and is one of the primary reasons everything (that we experience) holds together rather than collapsing in on itself into a black hole.

I think we agree that he implies that the outer limit is the electromagnetic force from the nucleus to the electron. But wait... he is pulling a fast on us.

This is a 1/r potential. So it isn't discrete at all. How is it like a box? This new question has answered part of our first question: He says that one end is the electromagnetic force. How can a continuous potential be treated like one that exists over a finite extent?


Or in other words: He says it is a box with well defined edges. But, it is more like valley (think of a bowling ball on a trampoline). A valley is not a box.

*promote... come on videosift... I can't give you the answers... let's hear some ideas.
