Doubting Rothman The article cites as fact Rothman s doubt that Young actually carried out his experiment spending a considerable amount of time on that issue It would be helpful to know who else doubts it besides those who accept Rothman on blind faith Repeating isolated theories as fact runs the risk of filling Wikipedia up with half truths shouted at full volume One could then sympathize with the man who wanted to charge 10 per printed Wikipedia article who when confronted with the statement in Wikipedia that it is free replied You believe everything you read in Wikipedia If Rothman is right about the experiment not having been performed we would have the interesting situation of someone who in a culture totally wedded to the corpuscular theory of light guesses its wavelength and then describes a gedankenexperiment that if carried out would demonstrate quantitatively the wave nature of light To accomplish this without actually doing the slit experiment he or an accomplice would either have had to carry out some other experiment yielding that information involving for example Newton s rings in which case why would he not report that experiment instead or be visited by a time traveler from the future Yeah I m not really sure why it s such a big deal for a scientist to reuse explanatory diagrams That seems to be the foundation of the entire suspicion It seems that this problem was disposed of long ago
