Penrose, Roger

Currently alive, at 84 years of age.
Nationality: British
Categories: Mathematicians, Scientist

1931 – Born on August 8th in Colchester, Essex, England. British mathematician and relativist who in the 1960s calculated many of the basic features of black holes.

1957 – After obtaining a Ph.D. in algebraic geometry from the University of Cambridge, Penrose held temporary posts at a number of universities in both England and America.

1964-1973 – He served as reader and eventually professor of applied mathematics at Birkbeck College, London.

         – He held the Rouse-Ball chair of mathematics at the University of Oxford.

         – With Stephen Hawking, Penrose proved that all matter within a black hole collapses to a singularity, a geometric point in space where mass is compressed to infinite density and zero volume.

         – Penrose also developed a method of mapping the regions of space-time surrounding a black hole. (Space-time is a four-dimensional continuum comprising three dimensions of space and one of time.) Such a map, which is called a Penrose diagram, allows one to visualize the effects of gravitation upon an entity approaching a black hole.

1989 – Wrote "The Emperor’s New Mind".

1994 – He was knighted for his services to science.

         – He wrote "Shadows of the Mind".
