"In fact, I once had a discussion with a distinguished astrophysicist who said to me, well, this is what Mach said, and this is what Mach did and what he required. And I said to him, now excuse me, if you don't mind me saying, what you've just told me is your interpretation of Dennis Sciama's interpretation of Einstein's interpretation of Mach. And he said you're quite right. I’ve never read a word of Mach."
