Matthew Choptuik
Matthew William Choptuik (born in 1961) is a Canadian theoretical physicist specializing in numerical relativity.
Choptuik graduated from University of British Columbia with a master's degree in 1982 and a Ph.D. from William Unruh in 1986 (Numerical Techniques for Radiative Problems in General Relativity). He became an associate professor in 1995 at the University of Texas at Austin. In 1999 he became a member of the Institute for Theoretical Physics at Santa Barbara and in the same year he became a professor at University of British Columbia.
In 1993[1], he discovered critical phenomena in gravitational collapse[2] via numerical studies. He showed - under non-generic initial conditions [3] - the possibility of the occurrence of Naked Singularity in General Relativity with Scalar Matter. This had previously been the subject of a bet between Stephen Hawking, Kip Thorne and John Preskill. Hawking lost the bet after Choptuik's publication, but renewed it under non-generic initial conditions. [4]
In 2003 he received the CAP-CRM Prize. In 2003 he became a Fellow of the American Physical Society. In 2002, he became an honorary doctor of Brandon University.
