Kenneth Leon Nordtvedt is an American physicist. He was born on April 16, 1939, in Chicago, Illinois. Nordtvedt graduated from the Massachusetts Institute of Technology (1960) and Stanford University (Ph.D., 1964) and was a junior fellow in the Harvard Society of Fellows (1963–1965). Soon after witnessing the Sputnik spacecraft cross the Boston sky in fall of 1957, he became a part-time student employee for the Mars Probe project at the MIT Instrumentation Lab, and in early 1960s was staff physicist at the same Laboratory's project to develop the Apollo Mission's navigation and guidance system.

Works

Theories of gravity

In 1968 Nordtvedt calculated how and to what degree the gravitational-to-inertial mass ratio of gravitationally compact bodies—bodies with significant gravitational binding energy—will generally differ from one in gravity theories other than

Wall Street Journal article featured on the front page.[4]

Tax policy

Nordtvedt was elected to three terms in the

Montana state legislature for a six-year period from 1979 to 1984, and there he wrote one of the first inflation indexing reforms of income tax law in the nation.[5]
He served briefly in 1989 as Director of the Montana Department of Revenue.

Nordtvedt is also an active
