This was great as it went farther than Rayleigh scattering. On this topic you have to watch this fantastic undergrad physics lecture demonstration: https://www.youtube.com/watch?v=sJG-rXBbmCc&t=1674s

#54Air is mostly nitrogen. Nitrogen gas is blue. There.
Go watch a video of nitrogen gas evaporating from liquid nitrogen ... tell me what colour you see?

Re: Why is the sky blue?
#57Really cool article! Tangential: > “Scattering” is the scientific term of art for molecules deflecting photons. Linguistically, it’s used somewhat inconsistently. You’ll hear both “blue light scatters more” (the subject is the light) and “atmospheric molecules scatter blue light more” (the subject is the molecule). In any case, they means the same thing There's nothing ambiguous or inconsistent about this. In English…
There are many verbs like this, and English is somewhat open toward using verbs that way, or becoming so.
Did English speakers say "this novel reads well" two, three hundred years ago?

#60I have a related but deeper question about sun and colors:
Sunlight in space is considered white. When it reaches earth surface, it's considered a warmer color. Why human eyes that never (during evolution) saw sunlight without the atmosphere, consider it true white, and not colder color?
