Описание к видео They Called His Bicycle Wheel 'Garage Junk' — Until It Calculated 14 U-Boat Kills in 90 Days

Royal Navy commanders rejected a mathematics teacher's bicycle wheel calculator as "absurd garage junk"—until it revolutionized U-boat hunting. March 1943, North Atlantic: Lieutenant Commander Harold Jennings, former Devon schoolteacher, invented a mechanical computer using a 26-inch bicycle wheel, fishing weights, and chalk that predicted submarine dive trajectories faster than any electronic system. His "ridiculous contraption" helped HMS Starling sink 14 U-boats in 90 days—the deadliest anti-submarine record of 1943. The Admiralty classified his invention for 44 years. He returned to teaching geometry, never receiving public recognition.
