Edwin Grosvenor writes of Bell's other extraordinary inventions: the first transmission of sound over light waves, metal detector, first practical phonograph, and early airplanes, including the first to fly in Canada.

A “lifer” at the secluded Academy of Florence, Leo has never met his parents ... or anyone in his family for that matter. His current “family” is his mechanical monkey and robot lion, who along with his charming best friend and fellow lifer, Savvy, only get him into trouble. But after Leo’s latest experiment goes catastrophically wrong, he finds a mysterious clue that opens an underground maze—one that seems to have been created for him to solve. Leo hopes the tunnels will help him discover the identities of his parents and the reason he’s an orphan in the first place.

Obsessive, brilliant, and tortured, Nikola Tesla was lauded for his invention of the alternating current (AC) and other significant contributions to science. His claim that “harnessing the forces of nature was the only worthwhile scientific endeavor" both impressed and enraged the scientific community. Eventually his peers could no longer dismiss his eccentricities and began to view him as a crackpot - a potentially dangerous one.

Before Isaac Newton became the father of physics, an accomplished mathematician, or a leader of the scientific revolution, he was a boy living in an apothecary's house, observing and experimenting, recording his observations of the world in a tiny notebook. As a young genius living in a time before science as we know it existed, Isaac studied the few books he could get his hands on, built handmade machines, and experimented with alchemy.

Few people are aware that John Moses Browning - a tall, humble, cerebral man born in 1855 and raised as a Mormon in the American West - was the mind behind many of the world-changing firearms that dominated more than a century of conflict. He invented the design used in virtually all modern pistols, created the most popular hunting rifles and shotguns, and conceived the machine guns that proved decisive not just in World Wars I and II but nearly every major military action since. Yet few in America knew his name until he was into his 60s.
