Paradoxes and Fallacies

[winterHLepsilon]

When a boy wanted to ask his girlfriend out to dinner he asked two questions. The first one was, (of course): 'Would you like to dine with me?' What was his second question?

"Pah."
Oh wait. How about:
"Pah?"

That definition of species does get rid of one paradox.

However, suppose A can produce fertile offspring with B, B can produce fertile offspring with C, but A cannot produce fertile offspring with C.

Which pairs of them are the same species?

[extropalopakettle]

"same species" is not transitive. A and B are the same, B and C are the same, but A and C are not the same.

So I read about the Tarski & Hutch paradox, or whatever it is, with the cutting the one sphere up into 5 bits and reasembling it into 2 identical spheres, and I've reached this conclusion: Mathematicians are goofy. With the corollary: Man, am I glad I didn't become a mathematician.

I'm surprised no one has mentioned the Twin Paradox.

The good think about math, is that when mathematicians go goofy, you can point to the exact spot in their proof where they did it.

Another fun paradox:

There are two envelopes on a table, exactly one of which contains $20. Written on the red envelope: Either this envelope contains $20 or the statement on the blue envelope is false. Written on the blue envelope: Either the statement on the red envelope is true or the red envelope contains $20.

Where's the $20?

[Vegetable]

In either of the two envelopes. IT'S NOT A FREAKING PARADOX!

[Mgm]

That would be the red envelope

[Vegetable]

Tell me why it can't be the blue envelope?

[extro...]

If it's in the blue envelope, then:

red : Either this envelope contains $20 or the statement on the blue envelope is false

blue : Either the statement on the red envelope is true or the red envelope contains $20

which is:

red : Either FALSE or the statement on the blue envelope is false

blue : Either the statement on the red envelope is true or FALSE

which is:

red : the statement on the blue envelope is false

blue : the statement on the red envelope is true

Now, if the statement on the red envelope is true, then the statemment on the blue envelope is false, and then the statement on the red envelope is false. Contradiction.

And, if the statement on the red envelope is false, then the statement on the blue envelope is true, and then the statement on the red envelope is true. Contradiction.

So what? What does it matter what the envelopes say. We have no reason to believe either is true. Read the "paradox" again. One of these two envelopes has $20. There's some writing on the envelopes.

[extropalopakettle]

[Dread Pirate Westley]

Neither do we have any reason to believe the statements are false.

Based on the scenario as described, it is possible that the writing is completely unrelated to the location of the $20. I probably wrote it on there to confuse any GLers who thought they could steal my money.

If you open the blue envelope, you get to go home with the $20, but if you open the red envelope, I can show you how far the bank vault goes.
