The author is ironically called "Tom Verde". Verde meaning green in Italian, Spanish, Portuguese and a few more languages.
And where we get the word "verdant"
> verdant: (of countryside) green with grass or other rich vegetation. > "verdant valleys" > "a deep, verdant green" Learned a new word! I wonder, however, if this word is ever used outside of SATs.
I always thought it was funny that Andrej Karpathy developed software for self driving cars - literally software for car paths.
Also I hear that the Carpathian Mountains have roadways. You're welcome :)
" Even the feathers of birds, from blue jays to bluebirds, are not truly blue but the result of a biologically sophisticated trick of the eye"

This is meaningless nonsense. If the light reflected or refracted by them is blue, then they are, indeed, blue.

It's badly described, but it's a reference to structural color. Engine oil isn't rainbow-colored, but it can produce rainbow reflections due to thin-film interference. Likewise, some animals have features that appear blue, but wouldn't yield a blue pigment because the color is the result of a particular microstructure.
