Neil Geoffrey Turok (born 16 November 1958[2]) is a South African physicist, and the Director of Perimeter Institute for Theoretical Physics.[3] His work has been in the area of mathematical physics and early universe physics, including cosmological constant and a cyclic model for the universe. Recent evidence for gravitational waves from the Big Bang appear to provide evidence against this model though the claim that the BICEP2 experiment has detected gravitational waves awaits confirmation. [4]

Early life and career[edit]

Neil Turok circa 1990

Turok was born in Johannesburg, South Africa, to Mary (Butcher) and Latvian-born Ben Turok, who were activists in the anti-apartheid movement and the African National Congress. After graduating from Churchill College, Cambridge, Turok gained his doctorate from Imperial College, London, under the supervision of Professor David Olive, one of the inventors of superstring theory. After a postdoctoral post at Santa Barbara, he was an associate scientist at Fermilab, Chicago. In 1992 he was awarded the Maxwell medal of the Institute of Physics for his contributions to theoretical physics. In 1994 he was appointed Professor of Physics at Princeton University, then held the Chair of Mathematical Physics at the University of Cambridge starting in 1997. He was appointed Director of the Perimeter Institute in 2008.[5]

Research and other contributions[edit]

Turok has worked in a number of areas of mathematical physics and early universe physics, focusing on observational tests of fundamental physics in cosmology. In the early 1990s, his group showed how the polarisation and temperature anisotropies of the cosmic background radiation would be correlated, a prediction which has been confirmed in detail by recent precision measurements by the WMAP spacecraft. They also developed a key test for the presence of a cosmological constant, also recently confirmed.[6]

Turok and collaborators developed the theory of open inflation. With Stephen Hawking, he later developed the so-called Hawking-Turok instanton solutions which, according to the no-boundary proposal of Hawking and James Hartle, can describe the birth of an inflationary universe.

Most recently, with Paul Steinhardt at Princeton, Turok has been developing a cyclic model for the universe, in which the big bang is explained as a collision between two "brane-worlds" in M theory. The predictions of this model are in agreement with current cosmological data, but there are interesting differences with the predictions of cosmological inflation which will be probed by future experiments (probably by the Planck space observatory). In 2006, Steinhardt and Turok showed how the cyclic model could naturally incorporate a mechanism for relaxing the cosmological constant to very small values, consistent with current observations. In 2007, Steinhardt and Turok co-authored the popular science book Endless Universe.[7] In 2012, Turok's Massey Lectures were published as The Universe Within: from quantum to cosmos.[8]

In 2003, Turok founded the African Institute for Mathematical Sciences in Muizenberg, a postgraduate educational centre supporting the development of mathematics and science across the African continent.[9]

Awards and honours[edit]

He was awarded the 2008 TED Prize for his work in mathematical physics and in establishing the African Institute for Mathematical Sciences in Muizenberg.[10] He also received a "Most Innovative People Award," for Social Innovation, at the World Summit on Innovation and Entrepreneurship (WSIE) in 2008.[11]

On May 9, 2008, Mike Lazaridis announced that Turok would become the new Executive Director of the Perimeter Institute for Theoretical Physics starting on October 1, 2008.

In 2010 Turok received a prize from the World Innovation Summit for Education in Qatar[12] and an award from the South African Mathematical Society.[13] In 2011 Turok received an Honorary Doctorate from the University of Ottawa.[14]

On November 3, 2011, Turok was selected to deliver the Massey Lectures for the 2012 season.[15] This involves five separate lectures to be delivered in various locations across Canada in October 2012, aired on CBC's Ideas shortly thereafter.[16]
