“Isaac Newton was brilliant about some things and a real kook about others. He spent a ridiculous amount of his time on alchemy.”
Newton was arguably the greatest physicist ever, yet kooks like you chide him for not also being a great chemist — back in what century was it?
That’s like saying that Joe Montana was not a great football player because he stunk as a linebacker.
LOL. No you simply didn't understand the point. It was that Newton was a great scientist in the area of physics, but was something a nut in other areas of endeavor. Alchemy is not science, it borders on magic.
I hope it is clear now.
