These classes explore how we use radioactive isotopes as cosmic clocks, a key tool in all sciences including cosmology. Atoms can act as universal clocks, even back to the Big Bang!
Our instructor is Dr. David Helfand, Chairman 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 Quest University (Canada), 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.
