    You can see wave properties from a double slit setup with your bare eyes. Here’s someone who did it with a cardboard box.

    If you setup a detector that measures which path the particles took, the interference pattern disappears- again something you can see with your bare eyes.

      For electrons you can’t do it. Either way the interference is not a quantum effect and the detector that you are talking about is a simple reemiting device that detects the wave vector and creates the wave in the same direction. Now live with that.

          Why are you giving me a theoretical paper? It doesn’t even have sizes, but I assume that the distance between two holes is about 1um, which you cannot see with your bare eyes

            So bacteria don’t exist either because you need a microscope to see them?
