Ok ,so unless im missing something this has got to be the strangest experimental conundrum iv ever seen it raises philosophical questions as well as scientific, I want to get a reality check because I think I might be giving this thing to much credit as far as its grandure and implications is concerned due to the lack of knowledge I have on quantum physics.

Here is the video but I suspect many of you know what Im talking about

A few questions ,does anyone know how many times and where these experiments have been conducted, were they done at universities or labs of the world?

And do we actually have recording devices that can record or measure electrons for us to view? am I right to be utterley at awe of this experiment or has there been a answer to this problem since then then?

Yes, individual electrons, a single electron, can be emitted, contained and observed.

Individual photons can also be detected.

This video is an example of the Copenhagen interpretation of quantum physics - reality only exists with the influence of consciousness, or something like that. It's now believed to be do you interference by photons and the detection apparatus, though there still are proponents of the interpretation.

What's even weirder is that light can be seen as either a wave or a particle, based on how it's observed. It has been stated that it naturally exists as a wave, but interference via consciousness or light causes the wave to collapse and become a particle. This also ties into the two slit experiment. At least this is what I came to understand years back when I was reading about quantum physics.

I found a certain site to be very good at teaching the various principles of quantum physics. It was my primary resource and it helped a lot with the initial confusion I had about it.
