Alfred A. Michelson

Alfred A. Michelson was a renowned American physicist known for his precise experiments that studied the nature of light and the Earth's movement. He is best known for the Michelson-Morley experiment, which provided critical evidence against the "ether" theory and helped pave the way for Einstein's theory of relativity. His work fundamentally advanced our understanding of physics, particularly in measuring the speed of light and exploring the properties of waves. Michelson's contributions earned him the Nobel Prize in Physics in 1907, making him a key figure in modern scientific inquiry into the nature of the universe.
