All numbers are equal
Theorem: All numbers are equal.
Proof: Choose arbitrary a and b, and let t = a + b. Then
a + b = t
(a + b)(a - b) = t(a - b)
a^2 - b^2 = ta - tb
a^2 - ta = b^2 - tb
a^2 - ta + (t^2)/4 = b^2 - tb + (t^2)/4
(a - t/2)^2 = (b - t/2)^2
a - t/2 = b - t/2
a = b
So all numbers are the same, and math is pointless.

Dear Doctor Science,
Is there a reason for not ending a sentence with a preposition that you can think of?
-- John Mostrom from Seattle, WA
I must admit I don't know where you're coming from. Correct usage in English and Science is something I've devoted my whole life to.
Of course, if I say anything you can't understand, it will just become a new hammer you can try to hit me or another expert over the head with. There are plenty of people like you I can't hope to change the mind of. But then, I've dealt with people like you before. People who don't really want to learn, but just hope to find someone they can publicly disagree with. There's little I can say that your type won't find something to object to. But getting back to your question, no, there's really no reason for not ending a sentence with a preposition, at least none I can think of.

First-year students at Med school were receiving their first anatomy class with a real dead human body. They all gathered round the surgery table with the body covered with a white sheet.
The professor started the class by telling them "In medicine, it is necessary to have 2 important qualities as a doctor. The first is that you not be disgusted by anything involving the human body."
For example, the professor pulled back the sheet, stuck his finger in the butt of the corpse, withdrew it and stuck his finger in his mouth. "Go ahead and do the same thing", he told his students.
The students freaked out, hesitated for several minutes but eventually took turns sticking a finger in the butt of the dead body and sucking on it.
When everyone had finished, the professor looked at them and told them, "the second most important quality is observation. I stuck in my middle finger and sucked on my index finger.
Now learn to pay attention."
