Wave Theory ∩ Time

I took Physics in my Junior year in High School. I enjoyed it, we got to play with all sorts of things and perform many of the (safe) classic experiments in Physics. I also got a C since I didn't take the Calculus class needed for the Physics class until my second year in college.

Anyway, one of the experiments is called the Double Slit experiment: you aim particles at a mask with two slits in it. What happens is you get interference patterns which are a phenomenon of waves, not particles.

This classic experiment has been perfomed now with single electrons which are passed through a double slit in time. Read more in: New look for classic experiment (March 2005) - News - PhysicsWeb.
