Michelson is best known for the experiment conducted with Edward Morley, attempting to detect Earth’s motion through a luminiferous aether. This experiment is the basis for modern optical interferometry and the method is used by @LIGO to detect gravitational waves. (5/n)

Michelson did attend the Naval Academy. In the Navy, he repeated Foucault's experiment measuring the speed of light. His result was more accurate than the value I quote in Physics 101. By 1883 he measured 299,853 ±60 km/s. The lower end of the error bar grazes the accepted value: 299,792 km/s. (4/n)

In the episode “Look to the Stars,” a young Michelson performs various experiments and measures the speed of light.

The plot of the episode revolves around the Cartwrights helping him gain admission to the US Naval Academy. (3/n)

Michelson was born in Prussia but moved to the US at a young age. He grew up in little mining towns across California and Nevada.

In Nevada his family lived in Virginia City. 100 years later this would be the setting for the TV show “Bonanza.” This was too good for the writers to pass up! (2/n)

Albert Michelson, pioneer of optical interferometry, was born #OTD in 1852.

Michelson refined measurements of the speed of light, failed to find evidence of the aether, and developed a method that now underlies gravitational wave detection. 🧪 ⚛️ (1/n)
