ACYU talk event at Glendon: Putting Einstein to the test -Dr. Jerusha Lederman

et en francais

Hey everyone, This Wednesday November 21, 2018 at 5:30 pm in A002 at the Glendon Campus we will be hosting another fantastic talk by Dr. Jerusha Lederman. See map below for direction

About Professor Jerusha Lederman - Honours B.Sc in Space and Communication Sciences, M.Sc. in Astrophysics and Ph.D. in planetary / Atmospheric Physics. Specialist in educational development (improving methods of teaching and learning at the university level) and astronomy / public outreach.

Abstract - The Gravity Probe B (GP-B) Mission was a NASA / Stanford space project that in the early 2000s (2004) measured two effects of Einstein's theory of General Relativity (GR) with unprecedented accuracy. Frame dragging and the geodetic effect describe the warping and twisting of spacetime around massive rotating bodies such as Earth. Over forty years in development with a budget in excess of 750 million US dollars, GP-B lived up to expectations of being able to prove Einstein right or wrong. It also yielded several important spin-off technologies, such as Global Positioning System (GPS) technologies which are now so prevalent in our society. In this presentation, I review GR basics and present an overview of the GP-B mission including how York University’s contribution to the project through the radio astronomical technique of Very Long Baseline Interferometry (VLBI) was instrumental in putting Einstein to the test and observationally confirming his predictions about the Universe at large scales.

There will be food and drinks provided as usual. So come by for some an educational time.

The bus from Keele campus to Glendon leaves at 4:30pm. So be sure to be there.

The return bus to Keele from Glendon is at 6:45pm.
