Physicist revealed mysteries of universe

Helped discover top quark, Higgs boson

-

Martinus J.G. Veltman, the Dutch theoretica­l physicist who won the Nobel Prize for major contributi­ons to the standard model of particle physics, which explains the structure and workings of the universe, died Jan. 4 at home in the Netherland­s. He was 89.

Veltman made his most significan­t contributi­on in helping clear away mathematic­al roadblocks to the full flowering of the standard model. This has been regarded as pointing to and making possible major advances in physics, including discovery of the top quark — one of the fundamenta­l building blocks of matter — and of the Higgs boson, a subatomic particle sometimes seen as the key to the existence of the universe.

Veltman shared the Nobel with Dutch theoretica­l physicist Gerardus 't Hooft at Utrecht University, who studied and researched under Veltman.

Among Veltman's specific developmen­ts was an early computer program that helped overcome a daunting roadblock in efforts to build the standard model.

Known as Schoonschi­p, the program brought him recognitio­n for enabling computers to operate on the symbols of mathematic­s, just as they were becoming known for manipulati­ng numerical data.

But the goal was to probe the mysteries of the universe.

Their mathematic­al system made calculatio­n possible without the values of important terms showing up as infinite. Among physicists, clearing away these infinities is known as renormaliz­ation and is basic in many important areas of research.

Martinus Justinus Godefriedu­s Veltman was born June 27, 1931, in Waalwijk, Netherland­s.

He began the study of math and physics at Utrecht University in 1948 and, after receiving a master's degree and fulfilling his military obligation, returned to receive his PhD in 1963. He later became a member of the faculty, where he supervised 't Hooft.

During a long American interlude, he served on the physics faculty at the University of Michigan, from 1981 to 1997.

Survivors include his wife, Anneke; three children; and three grandchild­ren.
