You should learn how constellations are moving with months of the year and you can remember the constellations as summer constellations or winter constellations according to your location.

Leonard Susskind started a program called continuing education to teach physics to anyone who has studied school maths at some point.

Autism is just masculine brain syndrome. It's only a problem because modern society expects men to act like women

If you had a projector casting CPL onto a wall, and a regular projector, you would not be able to tell which is which. Even through a linear polarizer(so we only line up and allow through full intensity twice per rotation), the freq of rotation is so fast that you don't see a difference in intensity.

I made this plot to help you out. E1 and E2 are not in the correct phase for the shown angle but it's close enough to grasp what's going on.

Now the questions are:
If I'm at rest and see CPL pass me, I see a 'vector' traveling at c with a rotating polarization angle.
So if I now say I'm traveling at the speed of light next to/with the CPL, what do I see? What is the frequency of CPL's polarization?
Some would argue that if I am indeed going the speed of light, thought experiment... , then we know time can not evolve and, because of this, they would say that the polarization angle of the wave would have to be constant. For that matter, all light traveling along the direction of our observer has constant polarization angles.
Now we have an issue. Two observers that are making two correct observations of the same physical process. Both of them see different things, yet they are looking at the same thing. How does one describe the physical process that is occurring?

It's like a barbers pole (candy cane) if it was mounted at one end and grew out from the other. (ie. the part that exists is not changing/rotating but the pattern rotates as it grows(light propagating).) If you are still and circular polarized light (CPL) passes you, the polarization angle will appear to rotate as it travels. It's generally referred to as RightCPL and LeftCPL depending on the direction of rotation. It's used for thing like 3d movies'. It's how we get 3d with out red/blue filters and such of old.

You can create CPL by bringing two orthogonal E fields out of phase by 1/4 a wavelength which is allowed by superposition. You could do this with a quarter wave plate. You can use a half wave plate to invert the handedness of the wave(rightCPL to leftCPL and leftCPL to rightCPL).

You must be new here. Are you actually trying to find an unclassifiable number? Not like primes ever helped us!

Take the cosmology pill. Pi = 1 or pi = 10. Both are acceptable.

Reality. It won't happen because it can't happen. Face your reality and cope, Earthicans.

Of course we know why the speed of light is constant dude. It follows directly from Maxwell's equations. The only assumptions are the permittivity and permeability of free space are constants.

I have diagnosed dyslexia. Got my Ph.D. in physics. Take courses in Latin and Greek. They will help you internalize the structure of English. Take Linguistics classes. They will help you internalize the structure of language. It won't cure your dyslexia, but it will give you a toolset with which you can navigate your disability.

Correspondence principle only works on GR. Limit of low speeds reproduces classical mechanics. Continuum mechanics reproduces continuum mechanics. All is good.

Every instance of the correspondence principle applied with quantum mechanics is an asspull with no analytics.

It seems fairly intuitive to assert as true. This isn't a formal proof, but it should be good enough.
>Evens and Odds are equally distributed amongst the natural numbers.
>Half the time, dividing an even number by 2 will yield an even number
>Every time, multiplying by 3 and adding 1 to an odd number yield an even number
>In 2/3 of the cases, we return an even number after the operation
>Use recursive geometric series to find the average amount by which even operation reduces number (if even, reduce again)
>On average, odd operation triples value and adds 1
>If, on average, even operation reduces by more, then even wins
>infinite iterations, you hit 1.

Redpill doesn't even make sense here. How does one get redpilled on scientific principles? As opposed to bluepilled? I don't get it. Read the Feynman Lectures if you want to learn about quantum mechanics.
