- This puzzle was given to me by a friend Mr. L.Chandar who
- is with the Physics dept., Syracuse University. I've solved it
- and have really enjoyed spending several hours of the New Year's
- eve working on it. Here it goes :
-
- Given a plane and exactly 3 colors, prove whether or not it is possible
- to assign a color to each point of the plane in such a way that no two points
- exactly 1 inch apart have the same color. If the assignment is possible,
- suggest a way to make it; if not, explain why. (Note : The points of the
- plane form one continuum; they are not discretely placed as in a grid.)
- -----------
-
- Have a nice New Year.
