This book contains a multitude of challenging problems and solutions that are not commonly found in classical textbooks. One goal of the book is to present these fascinating mathematical problems in a new and engaging way and illustrate the connections between integrals, sums, and series, many of which involve zeta functions, harmonic series, polylogarithms, and various other special functions and constants. Throughout the book, the reader will find both classical and new problems, with numerous original problems and solutions coming from the personal research of the author. Where classical problems are concerned, such as those given in Olympiads or proposed by famous mathematicians like Ramanujan, the author has come up with new, surprising or unconventional ways of obtaining the desired results. The book begins with a lively foreword by renowned author Paul Nahin and is accessible to those with a good knowledge of calculus from undergraduate students to researchers, and will appeal to all mathematical puzzlers who love a good integral or series.

They used to live in England, but eight years ago his family suddenly packed up, moved away, and even changed their last name. Neither of his parents will offer an explanation or tell William why he has to keep his talent for solving codes and puzzles a secret. But then a special exhibit comes to the local museum: the Impossible Puzzle. The experts say it is unsolvable, but William's sure that he can crack it if he gets a chance"--Amazon.com.
