Roger Penrose, English physicist, mathematician, and philosopher, Nobel Prize laureate

Sir Roger Penrose is an English mathematician, mathematical physicist, and philosopher of science. He is Emeritus Rouse Ball Professor of Mathematics at the University of Oxford, an emeritus fellow of Wadham College, Oxford, and an honorary fellow of St John's College, Cambridge, and University College London. He shared the 1988 Wolf Prize in Physics with Stephen Hawking for the Penrose–Hawking singularity theorems, and the 2020 Nobel Prize in Physics "for the discovery that black hole formation is a robust prediction of the general theory of relativity". He proposed the Penrose triangle and corresponded with M. C. Escher, influencing his Waterfall and Ascending and Descending. Penrose's eponymous aperiodic tiling presaged the discovery of quasicrystals by Dan Shechtman.
