stock image, actual book may vary The international bestseller that makes mathematics a thrilling exploration. In twelve dreams, Robert, a boy who hates math, meets a Number Devil, who leads him to discover the amazing world of numbers: infinite numbers, prime numbers, Fibonacci numbers, numbers that magically appear in triangles, and numbers that expand without . As we dream with him, we are taken further and further into mathematical theory, where ideas eventually take flight, until everyonefrom those who fumble over fractions to those who solve complex equations in their headswinds up marveling at what numbers can do. Hans Magnus Enzensberger is a true polymath, the kind of superb intellectual who loves thinking and marshals all of his charm and wit to share his passions with the world. In The Number Devil , he brings together the surreal logic of Alice in Wonderland and the existential geometry of Flatland with the kind of math everyone would love, if only they had a number devil to teach it to them.

stock image, actual book may vary In January 1999, Sarah Flannery, a sportsloving teenager from Blarney in County Cork, Ireland was awarded Ireland's Young Scientist of the Year for her extraordinary research and discoveries in Internet cryptography. The following day, her story began appearing in Irish papers and soon after was splashed across the front page of the London Times , complete with a photo of Sarah and a caption calling her "brilliant." Just 16, she was a mathematician with an international reputation. In Code is a heartwarming story that will have readers cheering Sarah on. Originally published in England and cowritten with her mathematician father, David Flannery, In Code is "a wonderfully moving story . . . about the thrill of the mathematical chase" Nature and "a paean to intellectual adventure" Times Educational Supplement . A memoir in mathematics, it is all about how a girl next door, nurtured by her family, moved from the simple math puzzles that were the staple of dinnertime conversation to prime numbers, the Sieve of Eratosthenes, Fermat's Little Theorem, Googols and finally into her breathtaking algorithm. Parallel with each step is a modest girl's own selfdiscoveryher values, her burning curiosity, the joy of persistence, and, above all, her love for her family.

stock image, actual book may vary Which planet is usually closet to Pluto? If the answer to this question, problem 85 in Mr. Friedland's collection, seems obvious, then perhaps you should stop to reflect a bit, for the correct answer may astound you. The book presents, for the alternate consternation and satisfaction of the reader, fully 100 intriguing problems based on permutations and combinations, properties of numbers, algebra, geometry, and logic. All the problems are posed in the form of stories, and all require of the puzzlesolver the same curiosity as the protagonists in Mr. Friedland's little stories. You should approach each of these problems carefully, for elements of challenge and surprise are built into every one, and all are sufficiently difficult to tax the wits of the inveterate puzzlesolver. Though none of the puzzles here requires any more mathematical knowledge than highschool algebra and geometry, problems are sufficiently difficult to provide hours of enjoyment for the more mathematically proficient. Moreover, the author has tried to create entirely original problems, so it is highly unlikely that you will find any you have encountered in other collections. Concise solutions are provided.

stock image, actual book may vary Playing with mathematical riddles can be an intriguing and funfilled pastime as popular science writer Martin Gardner proves in this entertaining collection. Puzzlists need only an elementary knowledge of math and a will to resist looking up the answer before trying to solve a problem. Written in a light and witty style, Entertaining Mathematical Puzzles is a mixture of old and new riddles, grouped into sections that cover a variety of mathematical topics: money, speed, plane and solid geometry, probability, topology, tricky puzzles, and more. The probability section, for example, points out that everything we do, everything that happens around us, obeys the laws of probability; geometry puzzles test our ability to think pictorially and often, in more than one dimension; while topology, among the "youngest and rowdiest branches of modern geometry," offers a glimpse into a strange dimension where properties remain unchanged, no matter how a figure is twisted, stretched, or compressed. Clear and concise comments at the beginning of each section explain the nature and importance of the math needed to solve each puzzle. A carefully explained solution follows each problem. In many cases, all that is needed to solve a puzzle is the ability to think logically and clearly, to be "on the alert for surprising, offbeat angles...that strange hidden factor that everyone else had overlooked." Fully illustrated, this engaging collection will appeal to parents and children, amateur mathematicians, scientists, and students alike, and may, as the author writes, make the reader "want to study the subject in earnest" and explains "some of the inviting paths that wind away from the problems into lusher areas of the mathematical jungle." 65 blackandwhite illustrations.

stock image, actual book may vary Sam Loyd 1841 1911 was America's greatest originator of puzzles. For more than 50 years, his ingenious posers, appearing in innumerable newspaper and magazine articles, stumped and delighted an American public running into the millions. Four or five of his mechanical puzzles became national crazes. After Loyd's death, his son issued a vast collection of these problems in a book entitled "Cyclopedia of Puzzles" probably the most famous and exciting collection of puzzles ever assembled in one volume. Now Martin Gardner, a wellknown author of many science and puzzle books and articles, has selected the choicest mathematical puzzles contained in the long outofprint "Cyclopedia," editing each one for accuracy and clarity, but in such a way as not to sacrifice the unique style and historical flavor of the originals. This is the second volume of Gardner's selection to appear, and contains 166 of Loyd's most brilliant and original creations, together with the 150 line drawings and diagrams with which they were originally illustrated. A distinctive feature of this new selection is the analytical table of contents, which groups the puzzles according to the type of mathematical skill necessary to solve them. Whatever your taste in mathematical puzzles, you will be able to locate easily puzzles based on arithmetic and algebra; speed and distance problems; game theory; operations research; clock problems; plane geometry; geometrical dissection; route tracing and topological problems; counter and sliding block problems; sold geometry; and physics and calculus problems.
