Numbers equal zero

Theorem : All numbers are equal to zero.

Proof: Suppose that a=b. Then
a = b
a^2 = ab
a^2 - b^2 = ab - b^2
(a + b)(a - b) = b(a - b)
a + b = b
a = 0

Furthermore if a + b = b, and a = b, then b + b = b, and 2b = b, which mean that 2 = 1.

Statistical one-liner

Some statisticians dont drink because they are t-test totalers. Others drink the hard stuff as evidenced by the proliferation of box-and-whiskey plots.

Math is turning bad

Psst, cmere, said the shifty-eyed man wearing a long black trenchcoat, as he beckoned me off the rainy street into a damp dark alley. I followed.

What are you selling? I asked.

Geometrical algebra drugs.

Huh!?

Geometry drugs. Ya got your uppers, your downers, your sidewaysers, your inside-outers…

Stop right there, I interrupted. Ive never heard of inside-outers.

Oh, man, youll love em. Makes you feel like M.C. ever-lovin Escher on a particularly weird day.

Go on…

OK, your inside-outers, your arbitrary bilinear mappers, and here, heh, here are the best ones, he said, pulling out a large clear bottle of orange pills.

What are those, then? I asked.

Givens transformers. Theyll rotate you about more planes than you even knew existed.

Sounds gross. What about those bilinear mappers?

Theres a whole variety of them. Heres one youll love — they call it One Over Z on the street. Take one of these little bad boys and youll be on speaking terms with the Point at Infinity.

Log negative one zero

Theorem: log(-1) = 0
Proof:
a. log[(-1)^2] = 2 * log(-1)

On the other hand:
b. log[(-1)^2] = log(1) = 0

Combining a) and b) gives:
2* log(-1) = 0
Divide both sides by 2:
log(-1) = 0

Q: Did you hear about the statistician who invented a device to measure the weight of trees?
A: Its referred to as the log scale.

Dollars equal cents

Theorem: 1$ = 1c.
Proof:
And another that gives you a sense of money disappearing.

1$ = 100c
= (10c)^2
= (0.1$)^2
= 0.01$
= 1c

Here $ means dollars and c means cents. This one is scary in that I have seen PhDs in math who were unable to see what was wrong with this one. Actually I am crossposting this to sci.physics because I think that the latter makes a very nice introduction to the importance of keeping track of your dimensions.
