Gerard ’t Hooft
Gerardus ’t Hooft is a Dutch theoretical physicist and Nobel laureate. He shared the 1999 Nobel Prize in Physics with Martinus Veltman. Born and raised in the Netherlands, ’t Hooft studied theoretical physics and mathematics at Utrecht University, where in 1977 he became Professor of theoretical physics. He spent several sabbatical periods in Harvard, Stanford, Caltech and Durham, N.C. His early work with Veltman involved the question: how to renormalize the forces due to vector particles (particles with spin 1) in the formalism of relativistic quantized fields. Later, he turned his attention to the deepest remaining mystery in particle physics: how to “quantize” the gravitational force, and what the role should be of sub-microscopic black holes in this question. ‘t Hooft is Ambassador of the highly ambitious “Mars One” project, an attempt to realize the first human colony on the Planet Mars.
