These four classes explore how physicists and astronomers use stable and radioactive isotopes as cosmic clocks. They are key tool in all sciences including cosmology, even back to the Big Bang!
Our instructor is Dr. David Helfand, former Chair of Astronomy at Columbia University. As an observational astronomer he has researched and published on neutron stars, X-ray background, radio surveys. He is the former President of the American Astronomical Society, current Chair of the American Institute of Physics, and a well-known lecturer and author. This course is an elaboration of an AAA lecture Dr. Helfand gave in 2019. The title, “Universal Timekeepers“, is from his just-released book available from Columbia University Press or Amazon.
This is Part 2 of a two-part course. Part 1 was a single class preview/review of atoms and radioactivity Dr. Helfand gave recently. It can be viewed once you register for this course.
