Continuing its practice of spotlighting science greats who are obscure to most of the general public, Google on Wednesday dedicated its Doodle to mathematician Pierre de Fermat.

The Doodle, which celebrates Fermat’s 410th birthday, features a chalkboard with an advanced equation. When you wave your cursor over it, the type reads: “I have discovered a truly marvelous proof of this theorem, which this doodle is too small to contain,” a reference to Fermat’s Last Theorem (xn + yn = zn), which Fermat’s son was said to have found in the margin of a book with a note that the margin was too small to include the proof. Clicking on the Doodle leads to Google search results for “Pierre de Fermat,” including news and Fermat’s Wikipedia entry.
