In Zeno`s "Dichotomy paradox", Homer is attempting to reach a fixed spot (a stationary bus), he never reaches it because me must first complete an ever smaller half-distance unto infinity.

In Zeno`s "Achilles and the tortoise", Achilles is attempting to a catch a moving (albeit slow) target..the tortoise. Achilles will never catch the tortoise as whenever he reaches where the tortoise was, the tortoise has moved on. The distance between the two become infinitely small, but do not reach zero.

I saw paper presented on this years ago. Thought it was interesting paradox, but fails in the real world.

Because there aren`t currently any empty rooms. He only creates empty rooms when someone moves.

I :heart: Zeno! His Arrow Paradox still rules!

Isn`t that an oxymoron? :-/

You`d need an infinite amount of time to pass out all those keys...

That a mathematician that specializes in thought experiments would be a lousy hotel manager since he`d keep asking people to move around for no reason, causing an infinite number of people to leave without paying... "

when I learned this it was an example to teach induction. all induction is, is that, if you can prove that an `n` exists, you can prove an `n+1` exists too. its hard to grasp at first but it`s cake. also n has to be a number. you cant prove infinity and than infinity +1

also he pronounced aleph null wrong, or at least different than I`ve ever heard a professor say it.

Not quite, as what you`re describing is just an infinite number of increments in which to measure that second. It does not mean you cannot pass that second.

Sounds alot like Zeno`s [quote]Dichotomy paradox[/quote] which states that when Homer tries to catch a stationary bus, he`ll never reach it because before he reaches it, he must get halfway there. Before he can get halfway there, he must get a quarter of the way there. Before traveling a quarter, he must travel one-eighth; before an eighth, one-sixteenth; and so on.

Ergo, he must complete and infinite number of tasks, which, in theory, is impossble.

This fails to take into account whether or not the infinite number of toilets in the infinite number of rooms have been sanitized for the protection of the infinite number of guests.

"The solution is to multiply eternal judgement by the infinitesimally small likelihood of the existence of any god. Zero multiplied by infinity is zero. "

But infinitesimally small is not zero. Or have I misunderstood?

That is why religions use the concept of notional eternal unimaginable reward and eternal unimaginable punishment to justify ridiculous and counter-intuitive, not to mention potentially immoral, acts of limited though heinous impact in the real world.

The solution is to multiply eternal judgement by the infinitesimally small likelihood of the existence of any god. Zero multiplied by infinity is zero.

Another solution is to deduct the teachings that conflict with one or more competing religions which may differ in outlook, as infinity minus one or multiple infinities is zero.

We must also acknowledge real world ethics/morality multiplied by the near perfect probability that the real world exists.

Therefore, religion ranks zero against true impact in order of priority.

My two favorite infinity problems are:

1+2+3+4+5+6+ ... = -1/12

and

the number of numbers between 0 and 1 is greater than the number of counting numbers.
