Roger Penrose". The Gifford Lectures. 18 August 2014. Archived from the original on 11 October 2020 . Retrieved 7 October 2020. In 1955, while a student, Penrose reintroduced the E. H. Moore generalised matrix inverse, also known as the Moore–Penrose inverse, [29] after it had been reinvented by Arne Bjerhammar in 1951. [30] Having started research under the professor of geometry and astronomy, Sir W. V. D. Hodge, Penrose finished his PhD at St John's College, Cambridge, in 1958, with a thesis on tensor methods in algebraic geometry [31] supervised by algebraist and geometer John A. Todd. [32] He devised and popularised the Penrose triangle in the 1950s in collaboration with his father, describing it as "impossibility in its purest form", and exchanged material with the artist M. C. Escher, whose earlier depictions of impossible objects partly inspired it. [33] [34] Escher's Waterfall, and Ascending and Descending were in turn inspired by Penrose.

Finally, he suggested that the configuration of the microtubule lattice might be suitable for quantum error correction, a means of holding together quantum coherence in the face of environmental interaction. [88] John Penrose was appointed the Prime Minister’s Anti-Corruption Champion in December 2017 and was reappointed in July 2019. He was previously a Minister of State in the Northern Ireland Office from November 2018 to July 2019.

Vanessa Penrose". Abingdon School. 6 July 2012. Archived from the original on 27 March 2012 . Retrieved 13 August 2012.Following up his "weak cosmic censorship hypothesis", Penrose went on, in 1979, to formulate a stronger version called the "strong censorship hypothesis". Together with the Belinski–Khalatnikov–Lifshitz conjecture and issues of nonlinear stability, settling the censorship conjectures is one of the most important outstanding problems in general relativity. Also from 1979, dates Penrose's influential Weyl curvature hypothesis on the initial conditions of the observable part of the universe and the origin of the second law of thermodynamics. [49] Penrose and James Terrell independently realised that objects travelling near the speed of light will appear to undergo a peculiar skewing or rotation. This effect has come to be called the Terrell rotation or Penrose–Terrell rotation. [50] [51] A Penrose tiling Each shape represents a matrix, and tensor multiplication is done horizontally, and matrix multiplication is done vertically. That second proof was fueled by another stunning finding: after discovering “the hat”, Smith landed on another shape that did the same job and looks a bit like a turtle. Myers found that the turtle and hat were geometrically linked and led to a whole family of einstein shapes, the Times reported.
