Quite an amazing example of Quantum Physics...

It's taking ages and ages to load here but tell me it's not a cartoon doctor the whole way through 
There was a program called how long is a piece of string on recently that shows the experiment.

Sorry john but it is, I guess it was laymans terms in communicating something that to most people doesnt even exist as a subject

A guide to dimensions: http://www.youtube.com/watch?v=BWyTxCsIXE4&NR=1
Which is a good theorem to why ghosts do or do not exist, the existence of 'God' etc..

Oh, and i'm not in this for an arguement into whether the above are or are not true, that's peoples personal perceptions, its just good food for thought.

Meh, everyone who does a level physics has to know this.

Yeah, every person in the world does A-Level Physics these days.

To further this, i'm watching something now that confirms that in the last 4 decades there are random generators that only output zeros and ones. a Zero is 1 'bit' and a One is one 'bit'. After asking a person to press a single button, the machine creates 200 'bits' consisting of Ones and Zeros. On asking a person a yes/no question and considering the answer 'no' would be Zero and the answer 'yes' would become One, the human mind has influenced the outcome of the machine to be more heavily weighted toward One or Zero just by thought. Completely insane but true.

Except the human mind didn't influence the outcome.

Time goes slower if you travel faster is one of my favourites (Relative to the time at the location you started your journey). Might make for a good excuse if you get caught speeding  .

I think the best thing is, particles can be in two places at the same time.

This is just turning into a bunch of random physics facts...

No but the generator was infinitly random, how the person affects the outcome of the generator is still to this day a complete mystery. Where there were no questions asked, it resulted in an almost perfect 50/50 balance.

Ah the joys of noetic theory  Probably one of those things which no one will ever difinitively prove.

What i'd like to know is if an atom is the smallest level of a substance, but the atom is made of subatomic particles, then what are the subatomic particles made of, and further what are they in turn made of.....
It's these infinitesimal levels of existence that get the mind boggling.
The 'Scientific' world were in agreement that if you could take all the 'space' out of the distances between every atom and its electron(s) the entire universe and everything in it would be around the size of a garden pea.........now that's something tough to get your mind round!!

Atoms'a aren't the smallest level, we've known that for a while.
The LHC is trying to find out what the even smaller particles are.

We've just been doing a cryptography module at uni which involved quantum physics
Using these methods you can theoretically try decrypting every method (e.g. 1024 bit strings) at once, but then can only view one of them.
Very interesting stuff

I did degree level physics for a year at uni but then dropped it cos I decided I didn't want to spend the rest of my life with people like the ones in my class But the material iteself if soo interesting, I agree. I had an amazing book about quantum physics, if I can find it in the cupboard then I will let you know.

Do a bit of research about how the forces of gravity work on the subatomic level, and the theories about it coming from another dimension and hence it being such a weaker force than all of the others (Think how long it takes gravity to speed up a falling object, but how quickly the electrostatic force stops it dead when it hits the ground)

Aren't photons smaller than atoms?

This is mental, how would observing the experiment change the outcome?
