Earlier this week I attended a talk by **Sir Roger Penrose FRS** in celebration of the 100th anniversary of the publication of Einstein´s General Theory of Relativity. The talk was entitled **Einstein’s Amazing Theory of Gravity** and it was sponsored by the London Mathematical Society (of which I am a proud member) and held at the Science Museum as part of the November Lates events. It also coincided with the 150th anniversary of the LMS!

During his talk, Penrose indeed talked about Relativity and I would have preferred that he concentrated on the theory per se at a more introductory level, after all it was part of a public talk in the Science Museum. He talked about black holes and did not shy talking about conformal geometries for example (bravo!). He finished his talk by presenting some of his own work regarding eons and cyclical cosmology. You can get a flavour of what he talked about in this recording of a lecture he gave in 2010.
