March 11 in Physics History - Births – Physicists born on March 11

Nicolaas Bloembergen (Born on 11 Mar 1920)

He was a Dutch-American physicist who shared the Noble Prize for physics for their revolutionary spectroscopic studies of the interaction of electromagnetic radiation with matter in 1981. He developed three-level pumps used in both masers and lasers.

Curt Brown (Born on 11 Mar 1956)

He is an American astronaut and pilot who made six Space space shuttle flights. His over 1383 hours in space began as a pilot of the Endeavour for an eight-day mission which was a cooperative project with Japan. He was spacecraft commander for three more spaceflights in 1997-99. After this, he retired from NASA. His crew installed new instruments and upgraded systems on the HST during his final mission.

Urbain-Jean-Joseph Le Verrier (11 Mar 1811 - 23 Sep 1877)

He was a French astronomer who predicted the existence of Neptune by mathematical means. He worked at the Paris Observatory for most of his life and switched from his first subject chemistry to teach astronomy at the Ecole Polytechnique. His main activity was in celestial mechanics. He calculated the position of Neptune from irregularities in Uranus’ orbit. When he asked the German astronomer Johan G. Galle to look for Neptune, he discovered Neptune after only an hour of searching, within one degree of the position that had been computed by Le Verrier. He gave the most striking confirmation of the theory of gravitation propounded by Newton. He also initiated the meteorological service for France.

Arthur Jeffrey Dempster (14 Aug 1886 - 11 Mar 1950)

He was a Canadian-American physicist who built the first mass spectrometer in 1918 and discovered isotope Uranium-235 in 1935. A mass spectrometer is an instrument that uses electric and magnetic fields to separate and measure a sample’s atoms according to their mass and relative quantity. Dempster worked with the secret Manhattan Project that developed the world’s first nuclear weapons during WW II.

Pioneer V Launched

On this day in 1960, Pioneer V was launched from Cape Canaveral, Florida, in one of the first in-depth attempts to study the solar system. It was carried into space on a Thor-Able three-stage rocket. It entered an orbit around the sun between Earth and Venus. It provided many important data on interplanetary space including measurements of magnetic fields, electric fields, cosmic radiation, and micrometeorites. It transmitted information until 26 Jun 1960 when it was 36 million km from Earth.
