This is off topic, but your signature line is not quite correct.
Most everyone knows that Paul Erdõs was a mathematician who turned amphetamines into theorems. He found those more effective than coffee.LGB wrote:"A mathematician is a device for turning coffee into theorems."~Paul Erdõs
In fact, according to Wikipedia's artical on Paul Erdõs:
"His colleague Alfréd Rényi said, "a mathematician is a machine for turning coffee into theorems", and Erdős drank copious quantities. (This quotation is often attributed incorrectly to Erdős himself.) After 1971 he also took amphetamines, despite the concern of his friends, one of whom (Ron Graham) bet him $500 that he could not stop taking the drug for a month. Erdős won the bet, but complained during his abstinence that mathematics had been set back by a month"
