For practical reasons, this experiment couldn’t be conducted until relatively recently, although within the physics community there was almost no doubt as to how it would ultimately play out. In 1989, Akira Tonomura of Gakushuin University and his collaborators performed the double-slit experiment with electrons, and you may not be the least bit surprised to learn that using an electron beam, they got exactly the same wavelike pattern of multiple fringes on the back screen (see below) as we did using a light beam.
9c). But he has long since left behind that sort of foolishness. Remember the two facts: 1. 3). 2. 3). The details obviously don’t matter too much, but the important thing is that according to Patches: 1. The beans take a far longer time to go from Rusty’s hand to splattering against the wall than Rusty says they do. 2. The beans don’t travel nearly as far as Rusty says they do. Special Relativity The point is that the beans are going far slower than our (and Patches’) original naive estimate. 44% the speed of light.
A. M. Dirac (1902–1984); Nobel Prize in 1933 Dirac was one of those guys who plugged through a set of equations, got something that seemed physically absurd, but decided that “God used beautiful mathematics in creating the world” and assumed that the equations must be correct, anyway. This, pretty much, is how he predicted the existence of antimatter four years before it was ever detected. 5. ” More on that in chapter 2. ” I f you’re anything like us, you have contempt for authority that is matched only by your zeal for life.
