Commentary

Why is Rainer Weiss remembered? Ever y major advance in physics was made by a person working to understand something that didn't quite make sense yet. Rainer Weiss was one of those people.

About Rainer Weiss Rainer Weiss ( WYSSE, German: [vaɪs]; September 29, 1932 – August 25, 2025) was a German-American physicist, known for his contributions in gravitational physics and astrophysi cs. He was a professor of physics at the Massachusetts Institute of Technology and an adjunct professor at Louisiana State University. 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. 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". Weiss helped realize a number of challenging experimental tests of fundamental physics. He was 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.
