Theorem 2.2(Interesting Theorem). All positive integers are interesting

Proof. Assume the contrary. Then there is a lowest non-interesting positive integer. But, hey, that's pretty interesting! A contradiction.

Theorem 2.3(Cat Theorem). A cat has nine tails

Proof. No cat has eight tails. A cat has one tail more than no cat. Therefore, a cat has nine tails.

Theorem 2.4(Salary Theorem). The less you know, the more you make.

Proof.

Postulate 1: Knowledge is Power.

Postulate 2: Time is Money.

As every engineer knows: Power = Work / Time

And since Knowledge = Power and Time = Money

It is therefore true that Knowledge = Work / Money .

Solving for Money, we get:


Money = Work / Knowledge

Thus, as Knowledge approaches zero, Money approaches infinity, regardless of the amount of Work done.
