Polarization (seq 1 of Common Sense Quantum Physics)

[bobconkl]

Polarized glasses block glare, or reflected, or polarized light. Your analogy blocks all but one direction of polarized light.

Doesn't the polarizer block ONLY the light that is polarized in the SAME direction?

@bobconkl I didn't understand the details of your question. Each particle of light (photon) has a state of polarization, which will interact with the electrons of the filter. If the photon will pass depends on a lot of parameters. Roughly said, a polaroid film blocks light that is polarized in the same direction as the direction of the molecules on the film. My explanation is really supposed to be an analogy where the directions aren't necessarily the same as at the scale of the molecules.

excellent video, so far ive been sifting through bs about quantum physics and contousness, so far this is logical and easily understandable, keep up the good work

your simplifying reminds me of my vid on economics 101

Did you film this is a zoo?

Nice Video!

Could it be that Time has symmetry and geometry? Newton believed Time was a thing in itself and connected to motion and Einstein believed there was something missing from quantum mechanics. In my video The Paradox of Schrodingers Cat an artist view it is Time that is the Hidden Variable.

Nice example of daily life.

Arjen,

You have a nice idea here: Make "common sense" of abstract concepts that are accessible to non-physicists. The diagram at 2:30 is good. The barrier to demonstrate spinning "arrows" (photons) moving through a polarized filter is clever too. Now, can you demonstrate why polarized light can seemingly change directions and sum after three perpendicular filters? I'd LOVE to see how you represent that!

Best Wishes!

Take apart an OLD cell phone with a color lcd and there is a plastic layer over the glass display. Take of this layer (DONT CUT YOURSLEF FOR DOGS SAKE!!!) , and look at the midday, southern or northern sky and rotate the glass as you look trough it, the sky will change color. If it doesn't work on one side flip it and try the other side. It's the coolest thing ever.

Its all in the stressfields

very nice video, plus it helps that you're nice to look at :-)

very nice

you remind me of my teacher, but I don't recall much b/c I fell asleep.

Interesting video. I am exploring a particle explanation for polarization in which the particle is a sphere of matter (not massless energy). It's interesting that the corpuscular theorists really failed to offer a variety of possible corpuscular explanations of polarization. Other phenomena I am looking at to interpret with a material photon are: double-refraction, diffraction, and interference. I think possible that polarization is because of direction of light through an atomic lattice.
