And of course you've already decided that the differences can't be measured. I'm just curious, do you consider yourself a 'scientific type?' If so, you're deluding yourself. Newton discovered his law by observing, not making A/B/X tests.
Wow, I didn't even catch this. You're holding up an alchemist as a paragon of observational science?
Newton was a lot of things, but he sure as hell wasn't even a scientist, at least in any modern sense of the term. Keynes once said that "Newton was not the first of the age of reason, he was the last of the magicians."
