Hello Experts, I leaned that using a sterescopic cameras (generates 2 photos) one can measure the distance to any object in the image produced by the camera. For example, if I take a picture of a lamp post using a stereoscopic method, I can determine the Distance from the camera to the lamp...

Thank you for that explanation. I now understand. However, how are the collisions "removed" in a perfect conductor like a super conductor?

The resistance increases because all the electrons tend to go to the surface. More electrons in a certain space = more resistance. I get it. However, since we are only moving 1 atom's length of distance - they would not hit so many copper atoms. Additionally, since we are only moving 1 atom's...

Hello Experts, I am a physics newbie with big ideas. I have a question. I am thinking about how to produce a zero Resistance Current. We know we can do this using super-conductors in sub zero temperature, but maybe there's another way. My assumptions (which could be wrong): 1) Resistance in a...
