comment Is electric current a scalar quantity?
@ACuriousMind - good point, I was think in terms of the question

comment Single particle passing through the double slit at a time
@JohnRennie - I think the question is slightly different, the OP is confused about why you need a single photon. And I think it's useful to have some different answers to the same question at different levels.

comment Why does the lake surface appear darker in some areas?
@GreenAsJade, yes I thought I made that clear, it was just an example.

comment Why does the lake surface appear darker in some areas?
In this image I suspect the lighting difference is totally from the surface, it is at such a low angle of incidence and the water is probably heavily sedimented (guessing from the location)

comment Why do snorkelers not need to wear corrective glasses when snorkeling with goggles on?
Also under water you can't see as far, visibility is at best 10m, and you aren't reading road signs or anything else in detail - so "in focus" is a bit less strict

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 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
