I continue to mine the AT&T video archive. Here's a really wonderful 1961 film showing how particles really are waves also. The simplicity of the gear that the Bell Labs folks used to demonstrate this is really admirable. I would love to see the preceding film (the one that shows how light waves are really also particles).

DeleteThanks - so if I was ever in Minnesota heading west I think I'd probably head to North Dakota to see the pyramid rather than to South Dakota for the corn palace although what about Rushmore ? - maybe someday someone will chisel presidents into the pyramid :)
