Smug media presentation enjoys bashing an old horoscope tradition with basic explanation on frame of reference. Water is wet.

You're awesome. I saw the Wiki article on this and I did not understand it. So I never thought about this again. Until today when this video was recommended. I get it now!

May be if we used our Sun's rotation to establish time we wouldn't have so much trouble understanding theses phenomena. You would think couldn't really matter, and maybe this particular situation does not. A little over two years ago I thought the little things did not really matter until I got schooled.

TL;DR
You know how when wheels spin fast sometimes it looks like they're spinning the opposite way due to the frequency your eyes pick up imagery?
That's what's happening here.

Why so many languages invented words for colors in the same order.

In 1969, two Berkeley researchers, Paul Kay and Brent Berlin, published a book on a pretty groundbreaking idea: that every culture in history, when they developed their languages, invented words for colors in the exact same order. They claimed to know this based off of a simple color identification test, where 20 respondents identified 330 colored chips by name. If a language had six words, they were always black, white, red, green, yellow, and blue. If it had four terms, they were always black, white, red, and then either green or yellow. If it had only three, they were always black, white, and red , and so on. The theory was revolutionary — and it shaped our understanding of how color terminologies emerge.
