More of John Gabriel's musings of late:

"I will point out a few facts about Hitler that most of you arrogant idiots didn't know or refused to acknowledge because your Jewish overlords do not allow you...

"Unfortunately, Hitler's henchmen got the wrong Jews...

"It would be a very good idea to round up all the academic idiots, gas them and incinerate the useless lot. Only those that pass John Gabriel's exam should be allowed to live."

-- John Gabriel, July 13, 2014

"I abolished 'if and only if' definitions because they are stupid!"
-- John Gabriel, August 7, 2014

More on John Gabriel's Wacky New Calculus. In his system:

1. He rejects the basic rules of logic.

2. He cannot prove something as simple as 2+2 = 4.

3. There are no irrational numbers, so the distance between (0, 0) and (1, 1), for example, is undefined.

4. There is no such thing as instantaneous speed. (As such, he doesn't know what to make of speedometers on cars that actually show your instantaneous speed. Another "Jewish conspiracy," JG?)

5. Having abolished 'if and only if' definitions, he cannot define what he means by a differentiable function. He cannot even define what he means by the set of even numbers!
