Just a thread for people to talk about quantum physics. It rocks, doesn't it? The wierdness +randomness of it all!!!!!

Calm down. It is indeed random.

Yay random things! Is quantum physics string theory and all that?

Yay! Random. Does anyone actually know what quantum physics is? I don't.

Breifly, quantum physics states that electrons and all the other particles follow no order; they are truly random. It's all to do with light, quanta (blips of energy) and black boxes. There's lots of stuff.

oh ok. Random confusing stuff. It does make a bit of sense though...

No, no it doesn't. If you think you understand quantum theory, you don't. That's the point.

Things are sort of fuzzy.

Finally. I've found other people who know about Quantum theory / Quantum Mechanics / String Therory / Superstring theory / M-Theory (I know most of those are very similar but oh well.
What I like is the fact it has a bloomin' good attempt at combing general relativity with quantum mechanics. Also the fact that nothing is certain makes it really interesting.
Has anyone seen the film What the bleep do we know? - it's a film based on quantum mechanics - they apply quantum mechanics to the larger world and shows you what happens.

I've heard of that. It was a load of *****s.

Is schrodingers cat quantum as well??

Yes. Shrodingers cat is the quantumness of something not being decided until it is observed.

Yep, coolios. Quantum is kinda fuzzy - did I say that before? Oh no, you did. Right, I better add something to this conversation. What?
String theory is at least an attempt.

Whatwith Schrodinger's cat, here's something exciting: When you observe Schrondinger's cat, and you find it dead, you haven't just killed it. The act of observing it creates a history in which either the cat's been dead or alive. Now hear this:
There are two cats in two boxes. Both of these boxes contain containers of gas with leaks in. One of these gases will make the cat immortal, and one gas will kill the cat. You put one container of gas in with one cat, and the other in with the other cat. You then close the boxes, and send them speeding of at nearly the speed of light, in opposite directions. A million years later, you return to one box. Imagine you open the box to find a dead cat. You know, instantanously, that the other cat must be alive. So you have created a history for the other cat to be alive. This history was created when you opened your box - so the information about this history has travelled the billions of miles between the boxes in an infinitely small time. Therefore, it is going faster than light. This is impossible.
