And of course don't forget: £12 billion. TWELVE fucking BILLION fucking POUNDS. To stage a 3 week sporting event, with no evidence of any economic or health benefits in return. Shameful.

Good for this guy, Hate the olympics, not usually but im a londoner. Not allowed to wear pepsi t-shirts, eat non-mcdonald fries, use a mastercard in the olympic village, zil lanes, not allowed to link to the locog website with 'derogatory' comments, locog refusing to release ticket details because all the prestige events sold to sponsors... All organised by that smug git Lord Coe. The sport comes a distant second.

The best part of this video is the Scottish television announcer.


That's Jim Watt.

According to QI they don't actually swim, they just walk along the bottom. Title fail.

Here's something I have never understood about Feynman diagrams, and I hope someone can explain it to me.
A Feynman diagram represents one possible way that two particles can interact, and from a single diagram you can work out the probability of that event occuring. But wouldn't there be an infinite number of ways an interaction could play out, and therefore an infinite number of diagrams? How do you know which one to draw?


It depends exactly what you mean. For an electron-positron annihilation/scatter, there are a couple of basic diagrams as he showed in the film. These are called "second order diagrams", indicating that there are two vertices. You can add in extra loops and vertices in the middle of the diagram to create third, fourth etc. orders, but each one contributes a very quickly decreasing amount towards the whole picture. I'm no physicist, but I think after the fourth or fifth order they're pretty much just ignored.

If you mean there are an infinite number of "things that can happen" for each input, then no; it's very limited by the rules of the diagram (mostly based around conservation rules - charge, momentum etc.). Drawing out the diagram, twisting it around and swapping the joins and vertices is a very good way of determining what the possible outcomes are.

Awesome. There's an official BBC HD version here.

That music is what they call Dubstep in Tijuana, Mexico.

It's what they call shite in my house.

The section at 3.10 is just fantastic. This deserves more votes.

Actually, Gwyneth Paltrow's head is in the box.


But is she alive or dead?

I bet poor Malcolm never used the snogometer himself.

Their Airblade hand dryer system that's all the rage in public toilets these days is awesome. It is undeniably faster and more cost effective than those piss poor fan systems. Plus they make me feel like I'm drying my hands in the future!


Seconded! The best "exhibit" in the Glasgow Science Museum is the hand dryer in the bathroom. (OK, the planetarium is pretty awesome too...)

If its cool to the touch and not noisy then that's fair enough , but 90% of what dyson market is bullshit over hype its the apple of housing goods.


I disagree; unlike Apple, Dyson are genuinely innovative in what they produce. They certainly share marketing methods and pricing strategies though.

All seems a bit fake to me.

Vomit rain!
Lay your lunch all o-ver the terrain.
Vo-mit rain!!
I turn my head here to avoid puking on myself
Cover your heads or you will feel the pain!


HAHAHAHAHAHA!

Hope the Dread Red P disappears soon!


Cheers, I'm not too fussed though.

Worthy of a link surely? Free and REALLY addictive.
