Learning the basic laws of physics - mechanics, thermodynamics, relativity, quantum mechanics - can be a struggle. But when that master of deduction, Sherlock Holmes, leads the way, those difficult concepts become crystal clear. Colin Bruce brings Holmes, Dr. Watson, Professor Challenger of Lost World fame, and other favourite Conan Doyle characters to life to solve a Baker Street dozen baffling science mysteries: Murder on a royal train - divers dead of heatstroke at the bottom of an icy sea - a mysterious lady whose brilliance is matched only by her evil - an epidemic of insanity among the world's top scientists. Bruce works out the apparent paradoxes of special relativity and quantum theory in visual and logical terms. The effect is extremely lucid, and very entertaining for the armchair scientist in all of us.
