There's a mathematical equation on the Google logo today, but it doesn't say what it commemorates - anyone know?

Pierre de Fermat's birthday - Google Doodle features chalkboard with equations

google did this before, with another design, if you just click on the google sign, this is what it says,

Hmm, if I drift over the logo, all it says is "I have discovered a truly marvellous.... etc" - nothing to tell me what it's about!
