It's a shame higher maths and physics tend to go over my head, as it deprives me of a deeper understanding of such a brilliant man. I believe truly intelligent people share Einstein's views on 'happiness', for lack of a better word (Aurelius, Socrates, Herman Hesse, Emerson, Mary Oliver, to name a few).

I have written an essay on a subject that ties in with the themes you discuss in this piece. It's fairly dense for this platform, but I think it might interest you.
