Google-Doodle-Leonhard-EulerIf you’ve Googled anything this morning, you’ve probably noticed that the site’s logo features an orb-shaped graph instead of a second ‘o,’ plus all sorts of equations like “V –E + F = 2.” The doodle is an homage to Swiss mathematician Leonhard Euler, who was born on this day in 1707. The man responsible for geometry, trigonometry, algebra, number theory and infinitesimal calculus, he also made significant contributions to the world of physics, mechanics, fluid dynamics and astronomy. He’s considered one of the most game-changing mathematicians ever.

Here, three great TED Talks about math to help you celebrate his birthday.
