"Twelve-year-old William Wenton is a puzzle-solving genius. He lives with his family in a quiet Norwegian town. 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.
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.

WHY GOD COULD NOT CREATE THE UNIVERSE WITH A DIFFERENT DIMENSION EVEN IF IT WANTED TO or perhaps anything else. Perhaps the universe must be the way it is. It seems that what is omnipotent is mathematics, elementary arithmetic, just counting. Yet even mathematics is not powerful enough to create a universe¿there are just too many conditions, conflicting. Existence is impossible. Beyond that for there to be structure is quite inconceivable. But the universe does exist, there are galaxies, stars, even the possibility of life. That life is possible merely allows it to exist but only with the greatest good fortune does it actually occur. Intelligence is vastly less likely, ability and technology far more improbable. That we are, what we are, seem so strange, inconceivable, that we are left merely with wonder¿and, as we seem unable to realize, the need for the deepest care, responsibility and gratitude. We have been given by the unbelievable benevolence of chance, no life, but life with the most wondrous part of the universe, the ability to think, to know, to create, to wonder¿and thus the demand that we use our most awesome gifts to protect them, to protect and preserve the world in which they exist, and the life, likely so rare if not unique in the universe, which has received these astounding favors of chance, that has been given by nature its most exalted constituents. What we are requires that we enhance what we are, what we are part of, to see, understand and be grateful. An exploration of the precise conditions required for the existence of humans in the universe. ...the author does an admirable job delineating the laws of physics without becoming too bogged down in complicated jargon, and he maintains a sense of wonder about the unique and random nature of the universe. He repeatedly celebrates our highly improbable achievements as a species, marveling at our ability to use the language of abstract mathematics to unravel the mysteries of existence. ... the prevailing tone of the narrative is clear and confident, marked by a meticulous attention to detail. An...often fascinating journey through the history of the universe and mankind. -Kirkus Discoveries
