James, I love it…, Feynman hits the nail on the head.
One good thing is that the more you know about the world and about physics, the better you get at guessing.
I am still working on my guess, and it’s slowly coming together im my head, in a nutshell, I am hoping to redefine F, where;
Up = Fdr = mc^2
Apart from being good at guessing, I have a GUT feeling about this one…
