Today new it is an actual interview (only hours before now) but Tomorrow it could be a legacy of scientific history. Brian Greene interviews Roger Penrose. Fortunately, Brian Greene is a knowledgeable interviewer. That he is "in the other camp" only makes it even more stimulating. I read Penrose’ book "Cycles of time" three years ago. The mathematics with the tensors and all that stuff stays hidden from me. But I have understood the core idea a little bit. I like that Penrose has a controversial point of view, be it his criticism of quantum physics, of the inflation theory or even of the idea that black holes would store information. Not to forget Penrose' own hypothesis about the cosmos (CCC). I like it not because he is necessarily right about everything, may be not but because he invigorates the astrophysical community and questions things that are perhaps too common sense these days.
If one has such a mental freshness at 89 years of age, I take off my hat full of admiration. It's a two hour interview that starts about 30 minutes after the video starts. It is not only an explanation of his mathematics and physics, it is also a journey through his life stations in the astrophysical development. Actually he knows exactly when he met whom, on which day since 1955 and what influence it had.
