comment Refraction of light marching band analogy
@JeroenMoons - how does the light know is possibly the most fundemental question in physic! One suggestion is that all paths are tried in multiple universes and we end up in the one with the shortest path. And that is one of the more 'sensible' suggestions

comment F-Mount to C-Mount and vice versa
If the mount you want to move TO is shorter then it's just a mechanical question - ask on photography. If you need to go from a shorter mount to a longer one you will need optics, which is a question for here and the answer is almost always - forget it.

comment Scientific Laws for Engineering Materials
You could argue that purely descriptive laws like Hooke's which just describe an observation but don't offer any explanation are different from some fundamental theory which predicts effects. But I don't know what you would call them other .

comment How can we count 17 particles in the standard model
I think it's more that there are 17 known particles which constitue the standard model - rather than the standard model predicts/requires exactly 17particles.

comment What is the relationship between the Young's modulus of a material and the elasticity of a free fall collision
@fffred it wouldn't rebound because it couldn't store the potential energy in deformation. It's one of those silly unmovable object vs irresistible force questions

comment How do HUD optics create readable text so close to the eye?
The same way that the crosshairs on a telescopic sight or the focussing circle on a camera are visible. The optics makes a virtual image of it at a greater distance - ideally at infinity.

comment What is the simplest way to perform a Cavendish experiment?
@WetSavannaAnimalakaRodVance, sorry 18th Century, it's standard history shorthand at least in British English. The experiment was done in 1799

comment How light years is measured?
@Floris if you are in charge of fixing the defn of 'year' and the speed of light is fixed then you can have pretty much all the decimal places you want ;-)
