Why do not Newton's laws of motion predict the anomalous precession of Mercury, gravitational lensing and other observed relativistic effects? Two shortcomings of Newtonian dynamics are identified.
The first is the choice of "time" as the evolution parameter. As in general relativity, the motion in Newtonian dynamics can also be viewed as along a geodesic with an appropriately defined metric. The second shortcoming lies in this metric itself.
The corrected metric leads to the Relativistic Newtonian Dynamics (RND), recently introduced in a series of papers in partial cooperation with J. M. Steiner, which predicts accurately gravitational time dilation, anomalous precession of Mercury, periastron advance of any binary, gravitational lensing, and light travel time delay (Shapiro delay).
About the Speaker
Professor Yaakov Friedman received his B.A. and M.Sc. degrees in Mathematics from the University of Moscow in 1971, and his Ph.D. in Mathematics from Tel Aviv University in 1979. From 1979 until 1987, he taught and performed research at University of California, at the Los Angeles and Irvine campuses.
In 1987, he joined the Jerusalem College of Technology (JCT), teaching and doing research in pure and applied mathematics, as well as in mathematical, theoretical and experimental physics. He has served as the Rector of JCT, and, for the last decade, has been the Head of Research Authority of JCT. Today, Professor Friedman’s primary research interest is mathematical modeling of physics. These models are based on symmetries and exploit techniques he developed in his earlier research.The predictions of his latest model for extending the Theory of Relativity are currently being tested at two synchrotrons in Europe.
Professor Friedman is the author of the book Physical Applications of Homogeneous Balls and has published over sixty papers in international journals in pure and applied mathematics, statistics, and mathematical and theoretical physics. His papers have over 1000 citations.
