I recall some comment he made a while back like "very recent" or "just in the past couple of years" or something like that, but the archive search function is broken for me, just says "File Not Found".
But to be honest, Newton lived a ridiculously long time ago. He published in 1687. There basically was no science at all before then. The word "scientist" barely existed. I am pretty sure there was not one telescope in the world. If you think everything post-Newton is "New physics" then by the same token, you'd call JS Bach pop music.
