comment How car headlight works?
Are you asking for the purpose or how it works? It appears (to me) that you are asking about the purpose, which, I think, isn't quite on topic here.

comment What's the difference between $10\%$ of $10\text{ cm}$ and $1\text{ cm}$?
+1 If that is correct, then David Z's edit to the question might be wrong(footing). Because, for some (which?) reason, the OP suspected something related to measurement.

comment What's the difference between $10\%$ of $10\text{ cm}$ and $1\text{ cm}$?
@user3532993 I don't believe that. First of all the quote is unbelievable by itself. But secondly, I don't believe that people have such good memory or accurate perception for such occasions. But I could be wrong.

comment Quantum Philosophy a la John Bell
@mbyrr If you can stomach it, you might read through all of these pages. I didn't; but apparently he studied physics. Maybe.

comment Lorentz's Amsterdam Proceedings 12:986 (1904) paper?
I also think 'Neér.' should be 'Néer.' as it probably stands for the French 'Néerlandais(e(s))' (which means 'Dutch'). (And, I'm not sure, but I would abbreviate that as 'Néerl.')

comment Lorentz's Amsterdam Proceedings 12:986 (1904) paper?
'Verl.' is probably short for 'Verlag', which is German for 'publisher'. So, I guess that is a mistake in that particular citation.

comment If empty space is not really empty, what does the space between an atomic nucleus and its electrons consist of?
I don't know, but I'd assume that the (most likely; probability amplitudes come into it) distance between the nucleus and the electron is much larger than supposed in your football analogy.

comment Ice cube on a scale
'It is obvious that I am assuming all the other parameters in the environment like pressure, temperature and humidity to remain constant.' That is not obvious. How could they (exactly), given your answer? :)

+1. BTW, what are we seeing in the picture? Is it a fly?

comment Why can't you hear music well over a telephone line?
@CarlWitthoft I never realised there was an actual (and intentional) filter (which would completely explain the "built to"; as in actual suppression). Do you (perhaps) have a reference of some kind?
