The principles of quantum mechanics from polarization

Looking at photon polarization, the formalism of quantum mechanics is developed.

This video focuses on the quantum formalism; other experiments like the double slit experiment might be better suited to explain the highly important quantum dynamics.

Best explanation of QM yet. Thank-you.

Is the photon coming out of a 45° polarizer in a superposition of both linear and vertical directions?

[christiansaint-pierre]

Ok, but why is it that when you add a 3rd polarized filter closest to the detector, positioned at a 90° angle to the FIRST filter (the one closest to the emitter), the detector registers photons?

this video is one of the best about the topic. Thanks

😇 Say thanks to you for your incredible enjoyable video, it is much appreciated and I really value your hard work !👍

This was helpful in better understanding radio wave polarization. A little 🫣😖 not a physicist, just a ham operator.

Wow, awesome video! I enjoyed it so much ... also I had to watch it multiple times >D

@ 2:23 Here YOU MISSED AN IMPORTANT POINT completely: the vector you mentioned is composed of a sum of other (basis)vectors and their components. This sum is the superposition you wanted to explain. Good you stopped making videos, you have no feeling (yet) for explaining things.

When light is parallel to the grid it is stopped by the grid. When light is perpendicular it passes.

Polarizer is a re-radiator, not a filter.

We should talk about the polarization of photons as they go through a polarizer. My graviton model says that a real photon is a virtual photon that is excited by an energy E = hf; basically the difference between a virtual photon (proven by the Casimir effect to exist) and a real photon is that the virtual photon can become energized by energy to become a real photon; like the way a light bulb can be energized by voltage. The surface area of an expanding graviton is a virtual photon. The surface area is expanding at the speed of light as an oscillating virtual (not energized) electromagnetic field. The oscillation of the surface is polarized. The graviton is allowed to spin as it expands, which causes the virtual or real photon to have a rotating electric field.

The expanding graviton is a suitable building block of spacetime. The fact that it's a complicated building block is just the necessary requirement to make the laws of physics work. How is a graviton complicated? (1) It's expanding with radius r = ct. (2) the surface area is a virtual photon. (3) An energized virtual photon is a real photon. (4) Expanding gravitons have ALL of the physics constants built into them. (5) Expanding gravitons are what wave function PSI is describing. (6) The operators of wave functions are characteristics of expanding gravitons. (7) Gravitons move past each other in a way that recapitulates the derivation of time dilation. (8) Gravitons are continually being generated. The rate of generation may be tied to the temperature in some way, such that the rate of generation was much higher during the big bang (to explain the inflationary epoch). 9. The center of the expanding graviton is allowed to move around. (10) the overlap of many gravitons creates the quantum fields of standard model particles.

Very sorry that this model is hard to read or get through, but if give the Expanding Graviton your consideration, then you can explain (1) dark energy as the total energy of all of the gravitons that exist multiplied by the energy it takes to stop a single graviton from expanding (which is a very small energy). You can explain why the big bang expanded. You can explain the inflationary epoch. You can explain quantum field theory.

Whatever loops or strings that the physics community thinks can explain what spacetime is made of, those are just subsets of the expanding graviton.. A quantum entanglement between two photons or two photons is very likely to be very similar to what a super-string is.

this is misleading. polarisation doesnt work by aligning. it filters.

polarisatio is a vector effect of the EM field. not a quantum effect.

Your polarisers are wrongly represented...

[praveenkumardhankar]

your animation is too simplistic. Just like people who visualize gravity with a flat trampoline.
