Professor David J. Helfand, Professor of Astronomy, Columbia University takes you through a Grand Tour of the Universe.
Astronomy is unlike other sciences in that there are no experiments we can perform or expeditions we can mount. We are reduced to passively observing the light the Universe sends us, some of which has traveled billions of years before falling on our telescopes. In this light, however, we can read the life cycles of stars and recount the entire history of the cosmos. Replete with colliding galaxies and a fly-through of the Universe set to the Blue Danube waltz, this lecture provides one-stop shopping for a comprehensive tour of all of space and time.
David J. Helfand, a faculty member at Columbia University for 43 years, served nearly half of that time as Chair of the Department of Astronomy. He is the author of over 200 scientific publications and has mentored 22 PhD students, but most of his pedagogical efforts have been aimed at teaching science to non-science majors.
Join us on this fascinating journey to contemplate the cosmos!
