Mirror apparatus
1924-26
used by Albert A. Michelson to measure the speed of light
The growing accuracy of scientific methods and observations in the late 1800s and early 1900s led to an extraordinary profusion of information about the natural world. Albert A. Michelson, a Jewish immigrant from Poland, was the first American to win a Nobel Prize in science. His work on the speed of light helped set the stage for Albert Einstein's theory of relativity. |
