I'm starting to understand the problem with that approach using non point-source light, but I'm curious if there is a way to turn sunlight into an effective point-source? I'm also curious if holographic film could be used to "straighten" the light passing through it...

Could you at least focus the sunlight into a pinpoint and capture it in a fiber optic cable? At the exit end of the cable, would it be closer to a point source?

Obviously the sun is not coherent, but the rays are fairly parallel. I would think you can Compress them into a similarly parallel beam with a smaller radius. Of course that beam could be directed with a mirror to aim it. What I'm not clear on is how long you could effectively keep the beam...

It seems like it should be easy to use two lenses to 1: focus light into a small point then 2: use a stronger lens past the focal point to keep the beams fairly parallel. Experimentally, I have not been able to achieve these results. I have an LED flashlight which can project a fairly tight...

If you were to release a free electron in a total vacuum what would its behavior be? Say you released it from the center of a sphere with a surface capable of detecting the electron when it comes in contact. Wouldn't you be able to calculate the speed and direction of the electron by the...
