Citizenfour (2014), 114 minutes. Laura Poitras (director)Introduction by Mariel Garcia-Montes (HASTS) and Michelle Spektor (SERC)Topic: Government overreach, Surveillance, AuthoritarianismCitizenfour gives audiences an exclusive front-row seat to the moment Edward Snowden changed history with his revelations of widespread government surveillance around the world. In June 2013, filmmaker Laura Poitras and journalist Glenn Greenwald met with Snowden confidentially in Hong Kong, where he handed over classified documents providing evidence of mass indiscriminate and illegal invasions of privacy by the National Security Agency (NSA). As the story breaks, they are forced to manage the raging media storm around them, and find their personal security and that of their loved ones under threat.Cinema at the Nexus is an institute-wide film series which showcases films/documentaries that grapple with pressing issues of our day aiming to make sense of what we are experiencing today.Other events in the series:Cinema at the Nexus: "The Cost of AI" | Introduction by Eric Robsky Huntley, October 27Cinema at the Nexus: Prisoner No. 626710 is Present | Introduction by Sana Aiyar, November 13Supported by the SHASS Dean’s grant, hosted by the MIT Libraries.Pizza and light refreshments will be served.Contact for suggestions and questions: doylec@mit.edu, szarko@mit.edu, turnator@mit.edu

Speaker: Jennifer Paulhus (Mount Holyoke College)Title: Automorphism Groups of Riemann SurfacesAbstract:Classification questions about automorphisms of compact Riemann surfaces date back to the 1800s. There has been renewed interest in these questions over the last 30 years as advances in computation have provided new ways to explore the area. We will talk about some of those advancements focusing on groups which are automorphisms in just about every genus they should be (particularly simple groups and the alternating groups $A_n$).
