Frustrated with the initial results, he performed his experiment again on top of California's Mount San Antonio, but with no luck.  
Frustrated with the initial results, he performed his experiment again on top of California's Mount San Antonio, but with no luck.  He redesigned the experiment in order to detect any effects caused by the earth's rotation; again, nothing.  His half-silvered, half-transparent mirror worked just fine; his telescope received each half-pulse, and there was no difference in speed.  An aether windspeed of only one or two miles per second would have had an observable effect, but none was seen.  FTP, name this experimenter who disproved the existence of the aether.
