### Mathematical Paris

#### Posted by John Baez

I’m in Paris from July 1st to 19th. Just for fun, I’ve started taking pictures of streets named after mathematicians. Can you help me find more of these streets?

Descartes you surely know. Paul Painlevé may be best known as a politician in France, but mathematicians know him for his work on differential equations.

I need to get Rue Monge and Rue Laplace! Do you know more streets in Paris named after mathematicians — especially near the 5th and 6th arrondisements?

There’s the Rue Henri Poincaré, but it’s out in the $20^{th}$.
