Anthony Rizzi, PhD

Founder and Director of IAP

Since Einstein first conceived general relativity, over 80 years ago, physicists have sought a definition for angular momentum in general relativity.  No satisfactory definition of angular momentum had been given. In 1997, Dr. Rizzi gave the first such definition thereby gaining worldwide recognition for his work in theoretical physics.  That same year he presented his findings at the international general relativity physics conference held in Jerusalem.  A layman’s magazine article on Dr. Rizzi’s discovery appears in "Science," October 1998, Vol. 282, No. 5387, pg 249. 1

He is uniquely qualified as both an outstanding theorist and experimentalist in general relativity, specializing in LIGO (Laser Interferometer Gravitational-wave Obser-vatory) related areas.  As senior scientist at the California Institute of Technology’s Louisiana LIGO observatory, he was responsible for significant developments in getting the instrument ready for the detection of gravity waves.  During this time, he taught graduate physics courses at Louisiana State University.  Dr. Rizzi continues his work in increasing our understanding of Einstein’s theory and of gravitational radiation.  He has also been a research scientist at Princeton University.  Industry is also no stranger to Dr. Rizzi.  Earlier in his career, he was employed for ten years as a Staff Physicist and Design Engineer for Martin Marietta (later Lockheed Martin) in Denver, Colorado.  His work included projects for the Manned Mars Craft, Mars Observer, and he has received the NASA Award, as well as, a Martin Marietta New Technology Award. He has over 30 years experience as a physicist.

In 1982, Dr. Rizzi received a BS in physics from the Massachusetts Institute of Technology (MIT); later he received his MS from University of Colorado and a Ph.D. in physics from Princeton University. His talents also include extensive computer programming experience and a strong background in advanced mathematics. Dr. Rizzi has used in his study of philosophy and theology the same rigorous, in-depth questioning self-study style that he used throughout his physics career. Over the past 30 years, he gained an extensive background in philosophy learning modern and ancient philosophy.  In his studies of philosophy, he concentrated on metaphysics, moral philosophy and the philosophy of nature and science.  In philosophy and theology, history is almost indispensable and he studied that field extensively.  In theology, he has an interest in the writings of the early Church Fathers.  Most especially, he is interested in medieval theology.  In July 2001, Ralph McInerny, renowned philosopher and author, invited Dr. Rizzi to speak at and participate in the week-long Thomistic Institute, University of Notre Dame.  An article from his talk, “The Primary End of Marriage”, is published in the Thomistic Institute proceedings. 

In October 2001, Dr. Rizzi was awarded a grant to write the book The Science Before Science: A Guide to thinking in the 21st Century.  An interview of Dr. Rizzi about the book appears in "Catholic World Report," July 2002. Dr. Rizzi has frequently been featured in TV, radio, and print media. In addition to his technical articles, he has written the books: Physics for Realists: Mechanics, Physics for Realists: Electricity and Magnetism, solutions manuals for each, and A Kid's Introduction to Physics (and Beyond).

Dr. Rizzi is blessed with a lovely wife and four lovely children.
