A book by Bela Bollobás

"The Author considers these problems to be the type that two mathematical friends would pose to each other and discuss over a cup of coffee in a lounge. I agree with that premise, they are not too hard and there is a proof that is relatively easy … see full wiki

A set of problems perfect for the "Here's a cool problem" games between mathematicians

Rating:

The 157 problems in this book are certainly challenging and it is clear to see how they can be characterized as problems one mathematician would pose to another over coffee. Nontrivial with unusual points of statement and solution, most have proofs that are short and direct. The coverage is broad; many areas of mathematics are represented in some form.
The first section of the book is the set of problems, followed by a list of very brief hints. Given that it takes 35 pages to list the problems and the hints only take up nine pages, the hints are often of dubious value. The last section is a set of complete solutions to the problems, if you cannot solve them; they are an opportunity to appreciate how well done the problems are and the educational value of the proofs.
"Here's a cool problem" is a game that mathematicians like to play with each other and those found in this book are definitely in that category.
