Sir Roger Penrose (born 1931), British mathematician, physicist, philosopher and author. Penrose is Professor of Mathematics at the Mathematics Institute, University of Oxford, UK. His research specialises in the study of mathematical physics. In 1974, he discovered the geometric formation now known as Penrose tilings where two tiles of a particular shape can be used to produce complex, non-repeating patterns. Penrose has also worked on black holes, cosmology, quantum mechanics and human consciousness. Penrose was awarded the 2020 Nobel Prize for Physics along with the German astrophysicist Reinhard Genzel and the US astronomer Andrea Ghez for his demonstration that black holes were an inevitable consequence of the general theory of relativity.
