Today’s Physics Nobel Prize to Rai Weiss, Kip Thorne, and Barry Barish for the detection by the LIGO experiment of gravitational waves is a well-deserved recognition of a remarkable achievement through perseverance. However, it is the nature of prizes such as the Nobel that they obscure the important efforts and insights of many scientists across space and time that lead to the result in question.

Stanley DeserThe extraction of a gravitational wave signal from the output of the LIGO detector requires understanding in advance what signals can be produced; these are based on numerical simulations of astrophysical events which provide templates that a signal must match.

This is possible due to the seminal work of Brandeis emeritus faculty Stanley Deser, with his colleagues Richard Arnowitt and Charles Misner, who developed the mathematical framework known as the ADM formalism, to treat general relativity as a Hamiltonian system; with this, the evolution in time of the gravitational field can be computed from initial conditions.

In addition, Stanley was instrumental in the LIGO experiment being funded in the first place. The story is best told by him in his inimitable style (here quoted from an email, and lightly expurgated):

“Marcel Bardon, then [director] of NSF physics, made me an offer I’d better not refuse. I was nominated to some advisory committee in order to plead for LIGO in front of my betters, who would then go to Congress, if convinced. Those were dark days for waves, experimentally; we (ADM) of course knew the Lord was not evil, but 3 suns’ worth we did not expect!….It worked quite well, and was duly made a line item.”
