The Art of Mathematics: Coffee Time in Memphis

The Art of Mathematics: Coffee Time in Memphis presents a collection of mathematical problems and explorations inspired by informal discussions between mathematicians. The problems span multiple areas including combinatorics, geometry, and number theory. The book contains over 100 problems organized into chapters, with solutions provided separately to allow readers to work through challenges at their own pace. The material ranges from accessible puzzles to complex theoretical questions that have engaged professional mathematicians. Each problem stems from real mathematical conversations that occurred during coffee breaks at the University of Memphis, where author Béla Bollobás spent time as a professor. The informal origins of these problems are reflected in their presentation style. The work demonstrates how mathematical discovery often emerges from casual intellectual discourse rather than formal research settings. Through this lens, it reveals mathematics as a social and creative pursuit rather than just a technical discipline.

Readers note this book provides engaging mathematical puzzles and problems suited for advanced undergraduates through professional mathematicians. Several reviewers mention using it successfully in math clubs and problem-solving sessions. Liked: - Problems build logically in difficulty - Solutions are thorough and instructive - Covers interesting topics in combinatorics, geometry, and number theory - Good mix of classic and novel problems Disliked: - Too challenging for beginners/non-math majors - Some solutions require advanced techniques not explained in text - A few typos in problem statements - Price high for length Ratings: Goodreads: 4.17/5 (23 ratings) Amazon: 4.5/5 (6 ratings) "Great for mathematically mature readers but will frustrate those without strong proof skills" - Amazon reviewer "Perfect for math team practice but overkill for casual problem solving" - Goodreads review
