Sir Roger Penrose

[stewamax]

OK – I’ll admit it – I am in awe of Roger Penrose.
The creative powers of many mathematicians and mathematical physicists appear to wane when in their forties, as pure mathematician GH Hardy (vide A Mathematician's Apology - CUP) lamented. Penrose, on the other hand, is still making startling, mathematically backed and testable proposals about the origin of the universe, and his Conformal Cyclic Cosmology developed over the last 25 years or so is somewhat mind-boggling, if - like Gerenal Relativity – it isn’t easily grasped by the non-mathematician.

He is still doing (specialist) chat-show conversations and lectures, and is utterly lucid.
He is 91.

When I saw the thread title my stomach sank. I feared he might have died.

Penrose gave a Gresham College lecture on cosmology, available on YouTube. It should have been aimed at the well informed layman, but actually started at PhD student level and got rapidly harder. Very clever man, no idea what he was saying from my rusty undergraduate physics perspective.
