Rafael Araujo’s illustrations are bafflingly complex—so complex that you might assume the artist uses a computer to render the exacting angles and three-dimensional illusions. And true, if you were
to recreate his intricate mathematical illustrations using software, it probably wouldn’t take you long at all.

A true Idiot
Apparently someone bid up to $3,000 - for a country with a current account balance of -$8,000,000,000 (2005 est), that may have been quite brave! (In other words, an 8 billion dollar loss)
Hmmm ... maybe they were planning on creating some "efficiencies" in the economy so it would make a profit?

Backwards Derivative Rules
I came up with two problems which I find interesting.
1)If f(x)+g(x) is differenciable at c, and f(x) is differenciable at c then is g(x) differenciable at c?
