educational stupidity

Move over Creationists, a "leftie" professor will top your act! It's fun with numbers.

1 + 1 = 2; 2 + 2 = 4; 3 + 2 = 5.

That's mathematics (rudimentary in the example) which is known as "the pure science" because it does not deal with actual objects although it is regularly applied to objective things, like gravity, or astrophysics or even those computer things that often plague us.
