Take a dart, any dart.

Standing 8 feet away you throw it at the board. The dart passes half way at some stage, 4ft , then passes the halfway point again, 2ft, then again, 1ft. This goes on forever, because no matter how small the half way distance gets, there will always be another half way point.
However we know the dart eventually hits the board. Is this quantum mechanics in action?

You really need to get out on the bike more

I think according to quantum mechanics there's already a small chance that the dart is in the board before you've thrown it....

All you have demonstrated is the repeated ability measure half distances. This is independent of the motion of the dart.

Welcome to the 5th century BC. This is Zeno's paradox, which simply expresses in words the mathematical fact that infinite sums can have finite answers.

did i use my left arm or the right one ?

I thought this thread was going to be about trains in Dublin....

You need to apply this theory to a bouncing ball and the height it reaches after each bounce. Does it ever stop bouncing if its' height after each bounce is half the height it started from ?

 

[cosmicbike]

Now you've invited gravity along, that's gonna make it a bit more complicated...

 

[mr_cellophane]

And the dart flys in a gravity free environment ?

No, but the original question did not include, and does not indeed need, to take it into consideration.

That said, assumption is the mother of all ****-ups, and I have assumed the dartboard is not mounted either in the floor or ceiling. Of course if it is on the ceiling there is every potential that the dart never hits it, if you have a weak/girly throw

That is entirely dependent on whether or not I have my glasses on.

Here's something we can all try at home.
take a peice of paper, rip it in half, and half again, and again, and so on.
eventually we will all have split the atom, easy!

Aparently, if you stand in a carrier bag and pull on the handles you can lift yourself up.

Quite so, in the same manner if you stand on a chair use a bit of rope and a hook on the wall you can pull yourself off.
