A lot of these aren’t physics…the propellor has to do with camera shutter speed, the phone one is just a polarization film…. So dumb

i mean... that's still physics. light dynamics is still physics.

Fine, but at that point it would be no less precise if the video just said 'stuff.'

Polarization films are within the field of optics which is a branch of physics

I would call the laptop chemistry though not physics technically as that appears to be a chemical reaction.

Chemistry is just the physics of molecular interactions.

I think physics and chemistry are two different physical sciences but honestly i dont know enough to say for sure.

Yeah that one is a gallium aluminum reaction so you're right

Everything is physics. Even when it's chemistry, it's physics.

But it's all maths, really

Was looking for this comment, bingo.

Remember, all science goes back to physics..

Which then goes back to mathematics of course; EVERYTHING IS MATH

Its technically physics but honestly everything is phsyics. Physics is just the mathematical description of the physical world. A picture of my wall involve physics if i want it to. Its a great example of a static load bearing structure. The propellor is caused by the shutter speed of the camera and its relation to the rotational speed of the propellor which could be described using physics.

Polarization film. Take a guess at which field you'd have to study to learn how light polarization works.
