the monty hall paradox

if you're given 3 doors, one has a prize, two don't

you pick a door, the host opens one of the other two doors and shows that it doesn't have a prize in it, and asks if you want to switch.

The logic is, you now have a 50/50 chance, but that's not the case.. As long as the host is being legit, when you choose a door, you are assigning that door a 1/3 chance to be a car, logically the combined probability of one of the two remaining doors to have a prize is 2/3. When the host opens a different door and show it to have no prize, they are assigning that door with a 0/3 probability of having a prize, and giving the remaining unchosen door a 2/3 probability of having a prize.

If the game is being played legitimately, you are ALWAYS better off switching. Of course, there are lots of ways that the game can be rigged to remove that. They can take away the ability to switch unless certain criteria, such as choosing a door with the prize or without it are met. If they always only ask about a switch when you've chosen the prize with your initial guess, switching will always lose.

It's basically Bertrand's box paradox

I'd think that the unstoppable object and the unstoppable force would just keep "pressing" against each other.

in that case, one of the uns stops being un.

If they're pressing against eachother in one place, then the unstoppable object has stopped.

If they're pressing against eachother on the move, then the unmovable object has moved.

Curry's Paradox [http://en.wikipedia.org/wiki/Curry%27s_paradox] is my favourite. It's a real head-scratcher that still doesn't seem to have a definite resolution. You can use it to prove anything. Watch:

"If this sentence is true, then Santa Claus exists."

Good, isn't it?

Curry's Paradox? That wouldn't have anything to do with Tim Curry, would it?

Ah an oxymoron. Frustrating things they be.

If you went back in time and killed your parents before you were born, you would obviously never be born, so how would you go back in time and kill your parents?

I've always thought the answer to that would be that something would happen to make it impossible to kill your parents.

Most of this stuff would go over my head, even if I was awake, but I'll take a swing anyways. If you multiply by zero, you get zero. So if you divide, would you get infinity? Because infinity goes into any number 0.000- times. Because it's infinity, you never find that 01 at the end, it's just 0's forever.

Or is that cheating?

It's like asking him to make a circular triangle - it's just an impossibility.

That barely counts as circular, it's just a bit curvy, but bravo non the less.

Your next challenge: a heptagonal dodecahedron.

oh i know this one they surrender (unless the unmovable object runs away : D)

I like, if god is omnipotent can he create an object so heavy even he can't lift it?
If he can't then he can't to everything.
If he can, then its something he can't do.

It could be argued that the thing you are asking of god is a paradox in itself, as no object could ever be too heavy. It's like asking him to make a circular triangle - it's just an impossibility.

If he can't do something, then he isn't Omni[del]scient[/del]potent. Which means he isn't God.

You mean Omnipotent, omniscient means all knowing.

fucking magnets
how do they work?


Schrodinger's cat is a good one but there are a lot of things that the standard set up does to eliminate the paradox

If a tree falls in the woods and it hits a mime, does it make sense?

No. That doesn't even tasty biscuits.

Ha, thanks for that.

OT: Curry's Paradox is my favourite, becuase it doesn't involve too much brain melting.

Failed at failing?

Well spotted! Knew it was omni-something...

God can make a stone so heavy he can't lift it.
And.
God could lift said stone.

You see god is so powerful that he is not constrained by the laws of logic any more than those of physics.
