Welcome to LearnEarlyOn! In this video discover why the speed bump you drive over every day was invented by one of the most important physicists of the 20th century!

The modern speed bump was invented in 1953 by Arthur Holly Compton, a Nobel Prize winning physicist and one of the most accomplished scientists in American history. Compton won the 1927 Nobel Prize in Physics for his discovery of the Compton effect, which proved that electromagnetic radiation had both wave and particle properties and helped launch the field of quantum mechanics. During World War II, Compton served as a key director of the Manhattan Project at the University of Chicago, overseeing the development of the first self-sustaining nuclear chain reaction that paved the way for the atomic bomb. After the war, Compton became chancellor of Washington University in St. Louis. It was there, in the early 1950s, that he noticed students and faculty driving at dangerous speeds past Brookings Hall, the university's main building. Rather than relying on signs or enforcement, Compton applied his engineering instincts to the problem and designed what he called a traffic control bump, a raised sinusoidal ridge constructed across the road that forced vehicles to slow down or suffer an uncomfortable jolt. The invention was nicknamed the Holly hump. It worked immediately. Other universities adopted the design and within decades speed bumps became a standard traffic calming device worldwide. Today speed bumps and speed humps are installed in parking lots, residential streets, school zones, and pedestrian areas in virtually every country on Earth. The man who helped split the atom and reshape modern physics also invented the simplest piece of road infrastructure in the world: a raised piece of asphalt with yellow paint. Watch as a tire rolls over the bump you hit every week, a grand 1950s university campus reveals where it happened, and a macro close-up of cracked yellow paint shows just how simple the Nobel laureate's most universal invention really is.
