It is very good but I would have liked to see a bit on quantum entanglement.
Will this do instead:Quote:

Nice and to the point. Cheers for that.Quote:
I watched it over xmas and my brain is still aching from accepting the idea that all atoms in the universe are connected and change if I rub my hands together...
It's only a finite possibility that electrons can tunnel to somewhere you don't expect them to be. in addition to thinking of them all being connected, it is more like an electron cannot ever pass through a certain point, but they tunnel through that point and when they do you cannot measure where they are: so there is as much chance that they are on the moon as anywhere else.Quote:

This is one of the reasons Moores law was predicted to end, so instead of getting faster speeds, manufacturers concentrated on multi-core processors.
my degree level chemistry is a bit rusty nowadays though...
I'm not a huge scientisty person but still enjoy it and Brian Cox is a breath of fresh air - anyone who publicly calls someone a nobber on Twitter for spouting rubbish despite being in the public eye and of that level of intelligence is well worthy of respect.
