Specifically at 9:00 in the video. She says that when you have a detector before both of the slits, this "forces the electron to collapse to just one of these (waves) and you see a single slit interference pattern." Is this the biggest lie in physics as her video title claims or is she greatly...

The woman in the video below is claiming everyone has the double slit experiment wrong. She is claiming that when electrons are detected as they pass through the slits decoherence does not occur, what is happening is that the electron wave only passes through one of the slits. Her "proof" is...

Thank you!!! This is exactly the type of brain exercise I need each night for an hour or so before bed. With a little review here and there I think I can follow the math. This is good as it puts some "meat on the bones" of the theory that words alone cannot manage.

Again thank you for taking the time to reply. I am by no means advanced in my educations but I did take 5 semesters of calculus in college, ending with partial differential equations so the math while difficult to "get back into" is not foreign to me. I love math. Don't get me wrong, but it's...

Okay thank you for taking the time to reply. I have re-read the paper and have a better understanding of the experiment. Unfortunately outside of math I don't think I'm going to be able to find an explanation for this that I can wrap my head around. When it comes to the last part of the...

I'm missing something here. I understand that when the orthoginal (to each other) filters are placed in front of the place the interference pattern disappears. The resulting waves cannot add/subtract from one another because their amplitudes are in different orientations. But what I'm not...

And yet a beam of light is still a beam of light. But seriously I'm referring to the wave nature of the EM field in that changes are detectable even to the naked eye if the conditions are right.

Yes, thank you. I have read that paper. I am trying to get a handle on the conditions that trigger an "interaction," which provides or doesn't provide which-way information and furthermore if the behavior of the electron changes at that moment or at a later time if there was somehow a way to...

If the interaction at the slit is the determining factor for an interference to occur or not occur then there is no strangeness to the double slit experiment. But it is deeper than that as indicated by the quantum eraser experiment since if information is gained and lost the interference...

A "beam of photons" refers to a collection of photons, the fundamental particles of light, traveling together in a defined direction, which can be characterized by its intensity, energy, and other properties

Hello all! I am a lifelong physic enthusiast. I hold a degree in Mechanical Engineering and used to teach physics and chemistry in high school. I can't get enough physics. Unfortunately, my 16 year old daughter who is currently taking AP Physics gets more than enough! I look forward to...

Consider the double slit experiment where electrons are used as the media that travels through the slits. A beam of photons is directed across one of the slit. On the other side of the slit there is a detector that can let us know which slit through which electrons pass. What happens if the...
