It’s just amazing to me how astronomers from 2-300 years ago were able to work all this out in the first place

Leibnitz/Newton

[Steely Tom]

Leibnitz vs. Newton was (to me anyway) a little like Apple vs. Microsoft.

Leibnitz was open about his discoveries with respect to Calculus, and his notation was easier to understand and to use.

Newton kept his work a secret, not wanting to reveal it until he had developed it to the fullest possible extent. Also his notation was more esoteric and obscure.

Leibnitz was an "open system," Newton was a "closed system."

For some reason, that image of Newton reminds me of Robert Plant.
