Rainer Weiss

(Redirected from Rai Weiss)

Rainer "Rai" Weiss (/waɪs/ WYSSE, German: [vaɪs]; born September 29, 1932) is a German-born American physicist, known for his contributions in gravitational physics and astrophysics. He is a professor of physics emeritus at MIT and an adjunct professor at LSU. He is best known for inventing the laser interferometric technique which is the basic operation of LIGO. He was Chair of the COBE Science Working Group.[1][2][3]

In 2017, Weiss was awarded the Nobel Prize in Physics, along with Kip Thorne and Barry Barish, "for decisive contributions to the LIGO detector and the observation of gravitational waves".[4][5][6][7]

Weiss has helped realize a number of challenging experimental tests of fundamental physics. He is a member of the Fermilab Holometer experiment, which uses a 40m laser interferometer to measure properties of space and time at quantum scale and provide Planck-precision tests of quantum holographic fluctuation.[8][9]

Early life and education

edit

Rainer Weiss was born in Berlin, Germany, the son of Gertrude Loesner and Frederick A. Weiss.[10][11] His father, a physician, neurologist, and psychoanalyst, was forced out of Germany by Nazis because he was Jewish and an active member of the Communist Party. His mother, an actress, was Christian.[12] His aunt was the sociologist Hilda Weiss.

The family fled first to Prague, but Germany's occupation of Czechoslovakia after the 1938 Munich Agreement caused them to flee again; the philanthropic Stix family of St. Louis helped them obtain visas to enter the United States.[13] Weiss spent his youth in New York City, where he attended Columbia Grammar School. He studied at MIT, dropped out during his junior year,[14] but eventually returned to receive his S.B. degree in 1955 and Ph.D. degree in 1962 under Jerrold Zacharias.[15]

He taught at Tufts University from 1960 to 1962, was a postdoctoral scholar at Princeton University from 1962 to 1964, and then joined the faculty at MIT in 1964.[10]

In a 2022 interview given to Federal University of Pará in Brazil, Weiss talks about his life and career, the memories of his childhood and youth, his undergraduate and graduate studies at MIT, and the future of gravitational waves astronomy.[16]

Achievements

edit

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

In 1973 he made pioneering measurements of the spectrum of the cosmic microwave background radiation, taken from a weather balloon, showing that the microwave background exhibited the thermal spectrum characteristic of the remnant radiation from the Big Bang.[14] He later became co-founder and science advisor of the NASA Cosmic Background Explorer (COBE) satellite,[1] which made detailed mapping of the radiation.

Weiss also pioneered the concept of using lasers for an interferometric gravitational wave detector, suggesting that the path length required for such a detector would necessitate kilometer-scale arms. He built a prototype in the 1970s, following earlier work by Robert L. Forward.[17][18] He co-founded the NSF LIGO (gravitational-wave detection) project,[19] which was based on his report "A study of a long Baseline Gravitational Wave Antenna System".[20]

Both of these efforts couple challenges in instrument science with physics important to the understanding of the Universe.[21]

In February 2016, he was one of the four scientists of LIGO/Virgo collaboration presenting at the press conference for the announcement that the first direct gravitational wave observation had been made in September 2015.[22][23][24][25][a]
