If a tree falls, does it make a noise if no one is there to hear it?
I expect you've heard it before, but I spent most of my German lesson thinking over this. :D

That's quite possibly the stupidest thing I've heard all week.
Well done.

AAAARRRRRGGGGGHHHH I hate science ESPECIALLY Physics but I think that the question is unanswerable myself you cant prove it does or doesn't make a sound without being around to hear it.
"Are you kidding me? Dave fell over last week and he hasn't stopped going on about it since!"
From Family Guy. Excellent stuff.

Hehe, my topic has caused you all to discuss quantum physics. And all I asked was if a tree falls down and no one was there to hear it, would it make a noise? :D
Good God, what a coincidence.

I agree, but what a useless maths fact there!

You can prove Geography - look, there's a rock.
Ah, Maths. If it's so provable, why does it contain a section of stupidity that they call probability then? Probability is basically a load of rubbish as far as pure maths goes, it sits on the fringes of estimation and gambling, not the most mathematical of functions really.
Quantum Theory is interesting and challenges you to think about the universe in different terms than you are usually used to. Anything that challenges your preconceptions and makes you think in different ways is good, but it always has it's heretics who are against it. Look at the whole androgyny thing, so many people just bulk at the idea of the sexes being challenged like that, even in today’s society.
Mind you, it’s not really surprising when there are children out there in the UK today who still think Germans are evil because their parents told them that, mainly because they themselves were educated that way from parents who had been at war and had no intention of challenging their own theories on the issues they saw in black and white. It’s a dangerous type of brainwashing that causes race riots and bigoted opinion. Makes me sick.

Einstein did not invent quantum theory! In fact, it went against everything he ever did, and made him question his own work. If you'd like to find out more read "Hyperspace" by a guy called Kaku.
Anyway, there are no absolutes in physics. You cannot prove that vibrations cause sound. You can support this theory by repeatedly noticing that everything that is vibrating is making sounds, and things not vibrating are not making sounds, but you cannot PROVE it. (In fact Maths is the only provable subject... once you actually prove a theorem it will remain true independant of anything else)
To give an example, let's take brownian motion. There is no proof that says that this is to do with molecules bouncing off each other. There is evidence to support this theory, but not one scientist has proved that this will always happen. In fact, the molecules may move just because you're looking at them, and they stop moving when you stop looking at them!
