I knew Samuel Goudsmit who attended school with Einstein, if you could call it that, Einstein never wore socks, rarely bathed, showed up randomly, came late and left early. Sam and George Uhlenbeck proposed the spin of the electron as the fourth quantum number in 1925. They did not get the Nobel for it but those that proposed the first 3 all got Nobels. It was just a matter of so many things happening and needing to attribute other topics. Sam gave the funniest seminar based on the letters between european physicists during the early 20th century. He was also an amateur Egyptologist and gave a very funny public seminar about it. The most inspiring evening I ever spent was when Sam invited Edward Teller to come give us a seminar on his modelling of the implosion of a hydrogen bomb and afterwards we all went out to dinner and I had the good luck to sit next to Teller and across from Goudsmit and an old American physicist Bill Scott. They told amazing stories about the debates their colleagues had during the golden age of physics in the early 20th century and tried to resolve a few with what had been learned since.Experimental verification Bending of light The first experimental confirmation of general relativity occurred in 1919 , shortly after the theory was published. Newton's law of gravity predicts that gravity will not deflect light, which is massless; however, the principle of equivalence, on which general relativity is founded, predicts that gravity will bend light rays. The nearest mass large enough to have a noticeable effect on light is the Sun. The apparent position of a star almost blocked by the Sun should be measurably shifted as the light from the star is bent by the Sun's gravity. As described above, observations made during the total eclipse of 1919 found the predicted shift. More recently, this effect has been observed in the form of gravitational lenses. If a galaxy is located directly between us and a more distant object, say a quasar, the mass of the galaxy bends the light coming almost straight towards us (but passing around the galaxy) from the more distant object. If the amount of bending is just right, light from the quasar that would otherwise have missed us is focused on us by the galaxy's gravity. When this occurs we may see two or more images of the quasar, dotted around the image of the intervening galaxy. A number of gravitational lenses have been observed.science.jrank.org I'm looking for a good history of the verification of the special theory that dates the first accepted verification. I have not found it yet. But it required the development of good particle accelerators and particle detectors. This is why I believe General Theory was verified before Special Theory. osulibrary.oregonstate.edu aip.org A history of particle accelerators: aip.org
