Rainer (Rai) Weiss (born September 29, 1932) is a professor of physics emeritus at MIT. He is best known for inventing the laser interferometric technique which is the basic operation of LIGO. Rainer Weiss was Chair of the COBE Science Working Group.[1][2][3]

Early life and education

Rainer Weiss was born on 29 September 1932 in Berlin, Germany.[4] Fleeing political unrest, his family moved first to Prague, in late 1932, and then to the United States, in 1938; his youth was spent in New York City, where he attended Columbia Grammar School. He studied at MIT, receiving his B.S. in 1955 and Ph.D. in 1962 from Jerrold Zacharias. He taught at Tufts University in 1960–62, was a postdoctoral scholar at Princeton University from 1962–64, and then joined the faculty at MIT in 1964.[4]

Achievements

Weiss brought two fields of fundamental physics research from birth to maturity: characterization of the cosmic background radiation,[3] and interferometric gravitational wave observation.

He made pioneering measurements of the spectrum of the cosmic microwave background radiation, and then was co-founder and science advisor of the NASA COBE (microwave background) satellite.[1] In 2006, with John C. Mather, he and the COBE team were received Gruber Prize in Cosmology.[2]

Weiss also invented the interferometric gravitational wave detector, and co-founded the NSF LIGO (gravitational-wave detection) project.

Both of these efforts couple challenges in instrument science with physics important to the understanding of the Universe.[5] In 2007, with Ronald Drever, he was awarded the Einstein Prize for this work.[6]

In February 2016, he was one of the four scientists presenting at the press conference for the announcement that the first direct gravitational wave observation had been made in September 2015.[7][8][9][10][lower-alpha 1]
