Gregg Hall (Porter Hall 100)

The U.S. State Department and Global Pittsburgh have asked five international public health professionals to convene and discuss their collaborations with Peace Corps volunteers.

School of Art Lecture Series

Tuesday at 5 p.m.

Kresge Theater, CFA

Los Angeles-based artist Simon Leung will be presenting his artistic media projects. His work focuses on the dislocation and disparities that are left in the aftermath of war.

Leung pulls his inspiration from objects, people, and writings that have been removed from their origins — whether through time, circumstance, or historical violence. He then recombines these parts to form new allegories that challenge the accepted meanings of his source material. Using the media of video and performance, Leung attempts to reinvent war stories of modern times.

Cosmology Colloquium: “Where is the Dark Matter?”

Tuesday at 4:30 p.m.

Doherty Hall A301D

Neta A. Bahcall, from the department of astrophysical sciences at Princeton University, will discuss her recent observations using the Sloan Digital Sky Survey.
The study used gravitational lensing to trace the mass distribution around galaxies and clusters of galaxies to the largest scale. Her research compared the observed mass distribution with light distribution; it showed that, while the mass distribution is considerably more extended than light on galactic scales, the mass follows light on larger scales.

Bahcall will discuss the implications of her findings for cosmology and the mass-density of the universe, as well as galaxy and structure formation.

Fixing the Sky: Rube Goldberg meets Dr. Strangelove

Thursday at 4:30 p.m.

Gregg Hall (Porter Hall 100)

James Rodger Fleming will be discussing his book, Fixing the Sky. The book won this year’s Sally Hacker Prize, an award given to books that focus on the history of technology. Fleming is a historian of science and technology and professor of science, technology, and society at Colby College.

In his lecture, Fleming will analyze the history of geoengineering since the late 19th century and its role in public policy.

Fleming was elected a fellow of the American Association for the Advancement of Science in 2003 and a fellow of the American Meteorological Society in 2010.

Imagining Planetarity

Friday at 4:30 p.m.

Adamson Wing (Baker Hall 136A)

Joshua “Sha” LaBare, the Humanities Center Postdoctoral Fellow, will be discussing his recent work in a lecture titled “The Ecology of Everyday Life.”

LaBare’s research focuses on studying the science fiction genre as a mode of awareness towards the everyday and questions how humans can better adapt to the changing global environment. His study frames adaptation as a scale-making process by which the local is made global and vice versa.
