Dear International students (from around the world),

The problems are not aimed at the ‘top-of-the-class’ but at every student who feels CHALLENGED by a problem that involves unusual, entertaining, and not-every-school-day mathematics.

The 51 PROBLEMS should be enough to keep most of you busy for 25 days. It will take some EFFORT before you see how to even approach one or more of the problems. Don’t just flash on them and quit. Think about each one carefully. Ask yourself what principles and equations are relevant to that particular situation. Do not fixate on getting the answer. We advise you to analyze the situation, using the tools you have been learning, and stop worrying about the answer; it will eventually appear, as though by MAGIC! If it doesn’t, you will still have racked up a lot of partial credit if you have documented a rational analysis of the situation.
