The STEMinar Series consists of a variety of talks related to Science, Technology, Engineering, and/or Mathematics. These talks are FREE and open to the public and take place throughout the Fall and Spring semesters. Pre-registration is required. Register or contact Continuing Education with questions or to register by phone at (630) 942-2208. For more information about each talk, see below.

Recordings of the talk will be available on this page approximately two weeks following the talk.
A New View of the Universe
Saturday, Feb. 20, 2021
Joseph DalSanto, Associate Professor of Astronomy, College of DuPage
For over 400 years we have used telescopes to view and study the universe at virtually all wavelengths of light. But now we have an entirely new way to see the universe: gravitational waves. First predicted by Albert Einstein, gravity waves were thought too weak to actually detect – until now. With the invention of the Laser Interferometry Gravity Wave Observatory (LIGO) we can now "see" waves of gravity as they traverse the universe. Discover how this technology works, what we are learning from gravity waves, and what this entirely new way to study the universe means for us.
