Today could be the brithday of Pierre de Fermat. He was a french mathematician and lawyer. Unfortunatly he was the most time lawyer. He is best known for „Fermat’s Last Theorem„, which he described in a note at the margin of a copy of Diophantus‘ Arithmetica. Pierre de Fermat made notable contributions to analytic geometry, probability, and optics. He is best known for Fermat’s Last Theorem, which he described in a note at the margin of a copy of Diophantus‘ Arithmetica.
Here ist a video, that shows the Fermat-doodle with music (Johann Sebastian Bach’s „Brandenburg Concerto“):
