  This book presents puzzles in perpetual motion brought to you from the prolific puzzle-master Ivan Moscovich. Many of these bright brainteasers focus on ingenious, moving mechanisms. Check out a perpetuum mobile invented by a famous American mathematician and see if you can successfully explain its theoretical principle of operation. A cartoon depicts a classic Lewis Carroll conundrum: there's a monkey hanging on a tree holding one end of a rope while a bunch of bananas balance the other end in a state of equilibrium. What will happen if the monkey starts to climb? Other problems deal with gears and levers, while still more shift to number, counting, and calculation challenges.
