Doctor Ecco's Cyberpuzzles

"Dennis Shasha is the absolute best puzzle writer alive" David Gelernter, professor of computer science, Yale UniversityIn 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.

Safecracking, bullying, marital infidelity and gambling have never before been explored with the mathematical acuity and whimsy of Puzzling Adventures. Collected and enhanced from Dennis Shasha's popular Scientific American column, here are thirty-five of the most innovative and emotive mathematical puzzles ever to appear in its pages. Edgy, challenging and representing the ultimate in recreational mathematical games, Puzzling Adventures dares the reader to work out the logic underlying venture fund investments, escape a Minotaur, catch a polar bear, play power politics, work out if a witness is lying, spy on contraband traders and verify DNA. An encrypted set of stories and commentary float above the puzzles. They need decrypting to discover their hints. The hints lead to a surprise-if the reader can work them out...

Reports from the cutting edge, where physics and biology are changing the fundamental assumptions of computing. Computers built from DNA, bacteria, or foam. Robots that fix themselves on Mars. Bridges that report when they are aging. This is the bizarre and fascinating world of Natural Computing. Computer scientist and Scientific American’s “Puzzling Adventures” columnist Dennis Shasha here teams up with journalist Cathy Lazere to explore the outer reaches of computing. Drawing on interviews with fifteen leading scientists, the authors present an unexpected vision: the future of computing is a synthesis with nature. That vision will change not only computer science but also fields as disparate as finance, engineering, and medicine. Space engineers are at work designing machines that adapt to extreme weather and radiation. “Wetware” processing built on DNA or bacterial cells races closer to reality. One scientist’s “extended analog computer” measures answers instead of calculating them using ones and zeros. In lively, readable prose, Shasha and Lazere take readers on a tour of the future of smart machines. 50 illustrations

Genius mathematician, Dr. Dennis Shasha, here sets out his latest book-length mind-twister. Made up of many smaller segments, some of which can be solved by ten year-olds and some which are more challenging, the detective work requires no more than high school geometry and junior high school algebra. In every case, imagination trumps knowledge. The puzzles are set in a larger story of a mathematical detective named Dr. Ecco, his nephew and niece, and Professor Scarlet, the narrator. Scarlet is essentially the Watson to Dr. Ecco's Sherlock Holmes, asking the questions a reader might ask. Each puzzle is posed in a plausible if imaginary real-life setting. There are no hidden facts, no abduction here, just deductive logic and mathematical thought. Overlaying these puzzles are the ramblings of Dr Ecco's old nemesis, Benjamin Baskerhound. He seems to be on the run, but he's trying to tell Ecco his whereabouts in a way that only Ecco will understand. The evidence builds up and readers are invited to send in their solutions. The winner will receive a pre-paid trip to the home of modern mathematics, Sir Isaac Newton's Greenwich Observatory.
