Famous quotes that get things wrong: Einstein

Albert Einstein is generally credited with the following thought:
The definition of insanity is doing the same thing over and over and expecting different results.
I'll prove that the quote is wrong by counterexample. Texas Hold 'em is a zero-sum game, which means it has at least one minimax strategy profile. Due to the fact that the outcome of any particular hand is determined not only by players' strategies but also in part by chance, it is possible for any player to lose a hand while playing his minimax strategy. The quote above advises a player to change his strategy in such an event. Since, by assumption, the player's strategy is optimal, this advice is absurd. QED.
