Daniel Gillion Governing With WordsPenn Lightbulb Cafe World Cafe Live, 3025 Walnut St.

Daniel Q. Gillion studies racial and ethnic politics, political behavior, public policy, and the American presidency. In his latest book Governing With Words: The Political Dialogue on Race, Public Policy, and Inequality in America, he tackles the direct influence politicians’ race-conscious speeches have had on government productivity and changes in societal behavior. He also examines how a shift to “colorblind” policies has unexpectedly reduced discussions of racial inequality. But for politicians, he says, talking about race is not as harmful as once thought and can actually be beneficial.

Expert faculty from the University of Pennsylvania shed light on their research in the arts, humanities, and social sciences at the Penn Lightbulb Café. It's an evening of engaging, stimulating conversation, with a Q&A session following each talk.

Presented by Penn Arts and Sciences in partnership with the Office of University Communications, Penn Café events are free and open to the public, but RSVPs are encouraged. For more information or directions, contact Gina Bryan at 215-898-8721 or email at bryangm@upenn.edu.

Menu items are available for purchase. Happy Hour pricing from 4–6 p.m.

Alessandra Buonanno Sounds of Silent: Listening to the Universe with Gravitational Waves Penn Museum, Widener Lecture Room

Women in Physics Public Lecture

Co-hosted by the Department of Physics & Astronomy

One hundred years after Einstein predicted the existence of gravitational waves on the basis of his theory of General Relativity, LIGO announced the first observation of gravitational waves passing through the Earth emitted by the collision of two black holes one billion three-hundred million light years away. The detection of gravitational waves constitutes a major scientific discovery, as it permits a new kind of observation of the cosmos, quite different from electromagnetic and particle observations. In this lecture Professor Buonanno will review experimental and theoretical aspects of the quest for gravitational waves, which culminated with the recent discovery by LIGO,  and discuss how those new astronomical messengers can unveil the properties of the most extreme astrophysical objects in the universe.
