Chromatic number of the plane

Dear Colleagues, What is the minimum number of colors required to color the plane having no two points at Euclidean distance 1 from each other having the same color? This problem is often called the Hadwiger–Nelson problem. It is one of those simple to state and hard to answer questions that regular...
