Hello everyone! My name is Charlie and I'm new to EVE and an aspiring trader. Simply put, I was looking for a corp that suits my ideals and Taggard is spot on. A couple notes about myself:

* Currently attending college(Comp Sci major).
* I invest in the stock market
* I believe firmly in working smart as opposed to hard
* I am not a communist

I look forward to meeting you all on a personal level in the future!

* I am not a communist

I'm sure that's what a commie would like us to believe.

You are never called upon to prove a negative. That's a law of logic.

Jokes are just that.

It's quite possible to prove a negative. There are many ways of doing so, one of the most common is to show that if one assumes the logical inverse of the negative to be true, it would lead to a contradiction.

No- you cannot "prove a negative" but you can use induction, which is a really nice second best. :p

There are things that can't be proven but solely because it is a negation does not mean it can't be. Observe:

Proposition:
There are no even prime numbers greater than than two.

This is a sufficiently "negative" statement, yes?

Proof:
Assume there was an even prime number greater than two. Since this number is even it can be divided by two with no remainder, but because the number is prime it can't be divided by anything. This brings about a contradiction causing our initial assumption to be false. Therefore there are no prime numbers greater than two.

The ability to prove negatives is rather fundamental to mathematics.

And, uh, sorry for the thread derailment.
