"Dennis Shasha is the absolute best puzzle writer alive."—David Gelernter, professor of computer science, Yale University In the tradition of Sherlock Holmes, Dr. Ecco is one of the greatest sleuths of our time, a mathematical wizard who uses logic and computer programming to solve crimes, find treasures, and explore space. Join his team, expand the frontiers of your knowledge, and match wits with him on intriguing cases like "The Virus from the Spy" and "The Secrets of Space" and "The Caribou and the Gas." The puzzles collected here require no formal background beyond arithmetic and elementary algebra—just lively curiosity and keen intelligence. With thirty-six illustrated cases organized around eight major mathematical themes (from Combinatorial Geometry and Geography to Ciphers and Secrecy) this book will encourage you to use your mind and your computer in ways you never previously imagined.
A collection of thirty-six baffling cases allows the reader to join mathematical sleuth Dr. Ecco in solving these baffling cases, which are organized around eight major mathematical themes, with the help of one's mathematical and computer skills. Reprint. 13,000 first printing.
A writer finds himself trapped in an isolated village where anything imagined becomes reality in this wildly inventive contemporary fantasy Hoping to write his book in quiet and seclusion, Horton Smith has returned home to Pilot Knob. Here, in the tiny village where he passed so many carefree childhood years, he is untroubled by the pressures of the big city and can freely answer the call of his muse. Of course, back in the city Horton didn’t have to run from dinosaurs. There were no cartoon hillbillies offering him moonshine, Don Quixote was content to confine himself to the pages of a book, and the Devil himself was not on Horton’s tail. Something very, very unusual is going on in Pilot Knob, and Horton Smith is determined to get to the bottom of it—if his own imagination doesn’t kill him first! In Out of Their Minds, science fiction Grand Master Clifford D. Simak changes gears, treating his readers to a delightfully satiric flight of fancy and fantasy. An award-winning author renowned for his remarkable visions of the future, Simak brings creatures and characters from humankind’s collective imagination to breathtaking life in this fast-moving and unforgettable tale.
This book describes projects in a Mathematical “Circle,” i.e., an organization that discovers and nurtures young mathematical talents through meaningful extra-curricular activities. This is the second volume in a trilogy describing in particular the S.M.A.R.T. Circle project, which was founded in Edmonton, Canada in 1981. The acronym S.M.A.R.T. stands for Saturday Mathematical Activities, Recreations & Tutorials. This book, Volume II, is based on the papers published in scientific and education journals by the Circle members while they were still in junior high school (some still in elementary school). In essence, it explains the purpose of the Circle. Volume I describes how to run a Circle, and Volume III explains what actually takes place in the Circle. All three volumes provide a wealth of resources (mathematical problems, quizzes and games, together with their solutions). The books will be of interest to self-motivated students who want to conduct independent research, teachers who work with these students, and teachers who are currently running or planning to run Mathematical Circles of their own.
