comment Layer thickness measurement
If you knew what the coating was and so its refractive index (eg MgF2) you could estimate the thickness just from the angle you see the magenta in white light.

It means that even very high power cables will be made of a number of thinner wires because once they are more than 1/2" thick the center is not being used efficiently.

comment When pressure is exerted on parallel hydraulic pistons, do they start extending at the same time?
As drawn both the bottom and top pipes go to the same reservoir so nothing would move at all - I'm not sure you can trust the diagram

Then of the same force acts on both cylinders at the same time - then they must both move!
