I always suggest looking at the quantum eraser experiment to see how bad common sense works with quantum mechanics. It's fairly simple but intuition fails most people when it comes to explaining how it works.
- gerdesj 1mo agoNo need for funky stuff, just do the classic (lol) Young's slits experiment which should be more than enough oddness for anyone. I was shown it at school, using microscope glass slides that we waved over a Bunsen burner running cold, to coat with soot. We then carefully etched parallel lines with a compass by hand. Our (~17 y/o) efforts were a bit random but we did get some smudgy banding results on the screen.
- ambicapter 1mo agoUsing a compass is interesting, use two razor blades taped together is much easier and it’s close enough to perfect parallel lines.
- gerdesj 1mo agoIt was the '80s so safety razor blades were available but in a posh public school (UK version) aged ~17, compasses were everywhere and large old style razor blades were not - the modern style razor with one or two thin blades was a thing. We could have probably got some needles from matron for a finer point, than a compass. Your pair of razor blades is a great solution.
