Howard Percy Robertson (January 27, 1903 - August 26, 1961) was a scientist known for contributions related to cosmology and the uncertainty principle. January 27 is the 27th day of the year in the Gregorian Calendar. ... 1903 has the latest occurring solstices and equinoxes for 400 years, because the Gregorian calendar hasnt had a leap year for seven years or a century leap year since 1600. ... August 26 is the 238th day of the year in the Gregorian Calendar (239th in leap years). ... 1961 (As MAD Magazine pointed out on its first cover for the year) was the first upside-down year—i. ... A scientist is a person who is expert in an area of science and who uses the scientific method in research. ... Wiktionary has a definition of: Cosmology For the jazz band, see: Cosmology (band) Cosmology, from the Greek: κοσμολογία (κόσμος world + λογια discourse) is the study of the universe in its totality and by extension mans place in it. ... 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. ...

Howard Percy Robertson (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 bachelor’s degree in mathematics in 1922 and a master’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.
