Jeez. I have been REALLY bipolar this week

I'm so bipolar all the time, it seems. I get happy, and not-so-happy a lot of the time, for no apparent reason, sometimes when I should be the opposite of that.
I guess the positive is that when I sasy not-so-happy, that's basically what I mean. I'm really not happy, and I'm a little depressed, but I'm not what I could call truly depressed. Just feeling a lot worse than usual.
Because usually I feel good...

This week has been SO hard. Swimming especially. And, I realized yesterday that I was coming down with some sort of sickness. I always just somehow figure it out, even before any real symptoms show up.
Today, I was feeling quite a bit worse, and I suspect that tomorrow I'll feel worse than I do today, but I hope not. I hope this passes quickly, because I have a meet on Tuesday next week, then, after that, a three day meet Friday, Saturday, and Sunday.

Therefore, today, I'm not doing dryland. It's very liberating.

Boring stuff now over, now to philosophy.
Me and one of the swim coaches have been doing a lot of talks recently. There were some things about evolution, and perpetual motion, and all that stuff.
But what I thought was most interesting was that no argument is perfect. All arguments have weaknesses.
Because, they're all based on little building blocks, but you have to assume those are true, to make your argument.

In a geometry proof, what you have to do, is take the simplest things, definitions and postulates, and use them to prove larger things, theorems and laws and the like.
So, you have to assume that the postulates are true.

Because, there is no way to prove them. They seem obvious, but you just can't prove them. Because, proving them would require using theorems, and those are only true if the original postulate is true...
Catchy, huh?
Even mathematics is based on assumptions about things.

Never, Ever Lose Your Curiosity...

...and your inexorable drive toward seeking the answers to "Why?".'re far from normal... in many ways. You may personally resent the challenge of at least one of them... but contributions to the sciences, arts, and philosophy have been greatly advanced by others similarly affected and motivated.

So can you!

Need names?

>> I'd just like to say, I


I'd just like to say, I dunno about your book, but in my geometry book it's the postulates that are built off of theorems. :P

Chad is correct!

Theorems are built upon postulates (axioms).

The interesting thing, however, is that theorems must be capable of being proven wrong when found to lead to erroneous or incomplete observations. Axioms are just discarded when found that they lead to misguided theorems.
