In quantum physics, the Heisenberg uncertainty principle, sometimes called the Heisenberg indeterminacy principle, expresses a limitation on accuracy of (nearly) simultaneous measurement of observables such as the position and the momentum of a particle. ...

One of Robertson's first landmark papers, a brief note in The Annals of Mathematics, series II, Vol 39, pp 101-104 (1938) entitled "Note on the preceding paper: The two body problem in general relativity" solved that problem within a degreee of approximation not improved on for many decades. Earlier work, such as the Schwarzschild metric, were for a central body that did not move, while Robertson's solution considered two bodies orbiting each other. Nevertheless, his solution failed to include gravitational radiation, so the bodies orbit forever, rather than approaching each other. This article needs cleanup. ... In physics, a gravitational wave consists of energy transmitted in the form of a wave through the gravitational field of space-time. ...

HowardPercyRobertson (January 27, 1903 – August 26, 1961) was an American mathematician and physicist known for contributions related to physical cosmology and the uncertainty principle.

Robertson was born in Hoquiam, Washington and earned a bachelorâ€™s degree in mathematics in 1922 and a masterâ€™s in mathematics and physics in 1923 from the University of Washington in Seattle.

In 1953, Robertson chaired an influential CIA committee which reviewed several well-publicized reports of unidentified flying objects (UFOs) and recommended what was essentially a domestic propaganda program designed to reduce public interest in UFOs via a covert, mass-media program of "training and debunking." This committee is now known as the Robertson Panel.
