The time President James Garfield wrote a mathematical proof

So, now that we've reviewed which U.S. presidents in history did the most to advance science, let's turn our attention to which presidents have done the most for math — and the time U.S. president James Garfield wrote a proof for the Pythagorean Theorem.


Commenter jztemple suggested that, though Garfield's term in office was only 200 days, he still deserved consideration as a top president for advancing the sciences, due to a math proof that he himself has written. Jztemple also sent us a link to this excellent video from Khan Academy, explaining the math behind Garfield's Proof.

The theorem is made all the more impressive by the fact that Garfield was not a mathematician by training. In college, he had instead studied ancient languages and literature, eventually becoming a Classics professor.
