Yes, Zeno's Paradox. My maths teacher told us about this. A hedgehog tries to get from one side of the road to the other, jumps halfway to the other side, then halfway from where he is now to the other side of the road. It was a hillarious lesson. So technically, the hedgehog will never get to the other side of the road. So many people couldnt understand this. They were saying "But he will only have to jump a centremeter" so i replied "Then he will jump 5mm".
This went on and on.

did u know that in theroy u can never actually make it to any destination?? this is because say between u and your computer screen there is a halfway point and between that half way point there is another and another and another and so on so the halfway points never end meaning the number never reacher 0 so u cant actually touch your computer screen in theroy of course it is physically possible but just think about that for a while and its a good excuse next time the mother of wife or other pants wearing weasle in your life asks u to do something.

But that is if and only if you move by moving half of the distance needed to move, then half of that, half of that, and so on.

But if I just touch the d@mn computer screen...

No, actually, in theory you can never actually make it to any destination if you follow the method of going in steps of half the remaining distance.

Bah. With my Delorean and the cruise control set to 88 mph, I can get to anywhere I want, anytime I want.

And I mean anywhere and anytime .

So there. :spit:

You wanna race halfway there?:D

Who travels half the distance anyway? That's stupid. Sterling Marlin never travels half the distance, and look at all the races he won!! Plus he got to drive VERY cool cars.;)

Rock on

Exactly the peice of information that was missing from the first post which would have had it make sense.

Well, ratio-wise one never reaches the destination, but if you've ever taken advanced math...

For example, have you ever done a math problem like this:

If a rabbit runs 4 miles in the first hour, 2 miles in the next hour, 1 mile in the hour after that, and so on, how many miles will he run in total? (if he keeps running forever)

The answer is '8 miles', by the way.

The way you wrote it was pretty vague - rather than "and so on" You need to include the information that the distance traveled each hour will be half the distance traveled in the previous hour. ....BUT, wouldn't the answer be close to 8 miles, but never actually reach a full 8 miles?

Given an infinte amount of time for the rabbit, or an infinite number of steps for the initial post, you do reach the destination. In a real (finite) world, you never reach it.

So, given an infinite amount of time, the rabbit would reach the eight mile mark - but he couldn't eat the carrot sitting there, because he just used up an infinte amount of time... which is to say all of time, so there is no more... but if time extends infinitely, there must be more...
