Ricci Flow Solution Poincaré Conjecture (Geometry) Coffee Mug
No need to be a mathematician or physicist or topologist to enjoy any of these gifts featuring the Ricci flow, a kind of nonlinear diffusion equation. For the record, the Ricci flow (named after Gregorio Ricci-Curbastro) was introduced by Richard Hamilton in 1981 in order to gain insight into the geometrization conjecture of William Thurston, which concerns the topological classification of three-dimensional smooth manifolds. The Ricci flow plays an important role in Grigori Perelman's solution of the Poincaré conjecture. Memorable geometric gifts for any fan of geometric flows!

I was originally happy about my purchase and Nana loved the gift. HOWEVER, the description specifically says that these are microwave and dishwasher safe, BUT the first time Nana put this mug in the dishwasher it was destroyed. Not impressed..
