A hard problem inspired by an easy problem

The following problem was problem 1 (the easy one) on the Maryland Math Competition 2009 (I will later report on how the students did on it). Show that for every...

Is posting about 17x17 problem BAD FOR ACADEMIA?

(The 17x17 problem has gotten far wider attention than I imagined--- Brian Hayes posted it on his website: here, and its also here and here. The last website is...

17x17: Comments on your comments

One of the comments on my last post, the 17x17 post, inquired if I am also interested in the other unknown grids (17x18, 18x18, 21x10, 21x11, 21x12, 22x10). I AM...

The 17x17 challenge. Worth $289.00. This is not a joke.

The 17x17 challenge. Worth $289.00. This is not a joke.

The 17x17 challenge: worth $289.00. I am not kidding. Definition: The n x m grid is c-colorable if there is a way to c-color the vertices of the n x m grid soThe...

An Undervalued Math Problem

As most of you know there are 7 problems worth $1,000,000 (see here). It may be just 6 since Poincare's conjecture has probably been solved. Why are these problems...
