"Zeno's Paradox"
Suppose you're travelling from point A to point B.
To reach point B, you must first travel half the distance.
Once you've arrived at the mid-point, you must then travel half the remaining distance.
But once you've arrived at the mid-point of the remaining distance, you still have to travel half the remaining distance.
In fact this series goes on "ad infinitum" Since it takes some time, no matter how small, to travel half of any given distance and since the remaining distance can always be divided in half, it will therefore take you an infinite amount of time to travel from a to B.
In short it is impossible to ever reach B, no matter what you drive!
Now, if that has'nt bored the pants off you, then, YOU NEED HELP!!
I really must get out more.

Sorry its not true.
Probably because of quantum.
The paradox is only valid if your speed drops by half each time you've covered half the distance. This means that as you travel infinitely closer to point B, your speed becomes closer to zero and it takes you an infinite amount of time to arrive.
This is known as 'Driving in London'.
In the real world your mean speed is maintained and yu arrive somewhat sooner.
talking about paradox's can somebody explain in simple language Schrodinger's Cat?
If I understand it right he says that the cat is alive and dead at the same time. I dont get it either the poison has killed the cat or it hasnt just because you cant see the cat how does this change that?

Because that's exactly the way quantum works. The particle is a probability between alive and dead at the same time, and you as an observer fix it into one of those states.
Absurd? Yes.
Doesn't make it incorrect.
Quantum is very very odd indeed, and Schrodinger spent quite a lot of time trying to prove he was wrong.
He wasn't.
If QM doesn't make your head spin, you haven't understood it.

The idea is, I believe, that until you see the state of the cat by opening the box, it might as well be alive or dead. Therefore by never opening the box, it is both alive and dead.
Or was that something else...?

Dead or alive - how do you know which is true ?
Therefore, until you look, it is impossible to know whether the cat is dead or alive. Therefore it's both "dead and alive" (or not dead and not alive).
Don't think too much about quantum theory - it'll mess up your mind.
Everything is Probability, probably.

-because you don't know whether the container with the poison in has smashed to kill the cat (something to do with an atom decaying). What I don't get is how can something be alive AND dead rather than alive OR dead?
