Join us to discover how astronomer Vera Rubin's persistence, after her work was initially dismissed, finally convinced the scientific community that dark matter might exist. It is now taken for granted that the universe is mostly dark, made up of particles that are undetectable even by our most powerful telescopes. This discovery of the possible existence of dark matter signaled a Copernican-like revolution in astronomy: not only are we no longer the center of the universe, but even the stuff we’re made of appears to be insignificant. By showing that some astronomical objects seem to exaggerate gravity’s grip, Rubin played a pivotal role in this discovery. Yeager tells the story of Rubin’s childhood fascination with stars, and her scientific education at Vassar and Cornell. She became a rarity, a woman in science, and her findings were equally incredible to her colleagues. Since some observatories still restricted women from using their large telescopes, Rubin was unable to collect her own data until a decade after she had earned her Ph.D. But in 1993 she received the National Medal of Science for her groundbreaking work. She’s also been memorialized with a ridge on Mars, an asteroid, a galaxy, and most recently the Vera C. Rubin Observatory—the first national observatory named after a woman.

From his first day at West Point to his years of deployment in Afghanistan, retired four-star U.S. Army General Stanley McChrystal is no stranger to the deadly risks of combat. Throughout his illustrious career and efforts helping business leaders navigate a global pandemic, General McChrystal has seen how individuals and organizations have failed to mitigate risk by focusing solely on the probability of something happening as opposed to the interface by which it can be managed. In his new book, Risk: A User’s Guide, McChrystal and co-author Anna Butrico offer a battle-tested system for detecting and responding to risk. This book offers an alternative way of maintaining a healthy "risk immune system" that involves monitoring 10 different dimensions of control the authors say can be adjusted at any time to effectively anticipate, identify, analyze and act upon the ever-present possibility that things will not go as planned. Join us as General McChrystal reveals an entirely new way to understand risk and master the unknown. NOTES Photo by Leading Authorities, Inc.
