"The more important fundamental laws and facts of physical science have all been discovered, and these are now so firmly established that the possibility of their ever being supplanted in consequence of new discoveries is exceedingly remote.... Our future discoveries must be looked for in the sixth place of decimals." - physicist Albert. A. Michelson, 1894 thats not really wrong though.,i think there is another part of the quote where he mentions powers.
Weird. Michelson was right and wrong at the same time, and ironically it was one of his own experimental results which led to Einstein's "relativity revolution", though not the Quanta. He was right in that the actual differences from classical theory are in the "sixth place of decimals" and further, but wrong to assume that they would be considered unimportant.
