I want to see the double slit experiment in person! The one where the observer effects the wave/particle state of an electron. Where would I be able to view this experiment? Is it on display in any museums? I'd probably be able to go to any university with a physics program to see it in person I suppose....

    I'm voting to close this list question (v1) as off-topic because it seems to be about geographic locations rather than physics. – Qmechanic May 22 '16 at 06:00

    @Qmechanic, give it a rest already. It's easier to just answer his question. – David Reishi May 22 '16 at 06:03

    @Nick Perez, I was about to answer the question but Qmechanic kinda spoiled the mood. Anyway, the best way to see the double-slit in person is to do it yourself. What you're referring to in your question is the "Quantum Eraser" version of the double-slit, which has to do not with electrons, however, but photons. All you need is a simple laser pointer and a pair of polarizing 3D movie-glasses. Here's a video that outlines the whole process: https://www.youtube.com/watch?v=R-6St1rDbzo (skip ahead to see the guy actually do it) – David Reishi May 22 '16 at 06:10

    What's with this endless fascination for a trivial experiment that everybody can do at home with a dark room, a few rays of sunshine, a little bit of aluminum foil (or some pieces of an old broken mirror) and a razor blade? Not even a laser is needed. – CuriousOne May 22 '16 at 08:24

    @DavidReishi: That's another trivial experiment that doesn't teach anybody anything of value about nature. – CuriousOne May 22 '16 at 08:26
  • The double-slit experiment exposes quantum effects only when individual photons are seen constructing the interference pattern, and particularly strikingly as a compound pattern arises when a fraction of the photons are located at a slit while others are left unobserved. Without decreasing the source emission rate at this level, you just get classical light wave behavior, aka optics. – Stéphane Rollandin May 22 '16 at 09:01
