Speaker: Joris Roos (University of Massachusetts, Lowell)Title: A fractal local smoothing problem for the wave equationAbstract: We will talk about a variant of the well-known local smooth- ing conjecture with times restricted to a fractal set. The frac- tal conjecture involves a new dimensional spectrum called the Legendre-Assouad function, which also comes up in the char- acterization of 𝐿𝑝-improving properties of spherical maximal functions. Joint work with David Beltran, Alex Rutar and An- dreas Seeger.

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 $A_n$).

The irony of artificial intelligence is that it often reveals more about human intelligence than machines themselves.From AI in the home to robots in the workplace, the presence of AI all around us compels us to question its potential and recognize the risks. What has become clear is that the more we advance AI technology and consider machine ability versus human ability, the more we need to mind the gap.Researchers at MIT have been at the forefront of this evolving field. The work presented in this exhibition builds on the pioneering contributions of figures such as Claude Shannon and Seymour Papert, while highlighting contemporary research that spans computer science, mechanical engineering, neuroscience, and the social sciences.As research probes the connections between human and machine intelligence, it also underscores the profound differences. With AI now embedded in everyday life — from smart assistants in our homes to robots in the workplace — we are challenged to ask critical questions about its potential, its risks, and the boundaries between machine ability and human capability.Join us in shining light on the tremendous promise, unforeseen impacts, and everyday misconceptions of AI in this riveting, interactive exhibition.Learn more about the exhibition.

Imagine different worlds in Cosmograph: Speculative Fictions for the New Space Age, an exhibition that brings art and science together to examine possible futures where outer space is both a frontier for human exploration and a new territory for exploitation and development by private enterprise.We are living at the dawn of a New Space Age. What will the future hold? Will space elevators bring humanity's space junk to turn it into useful material here on Earth? Will asteroid mining be the next frontier in prospecting? Will the promise of geo-engineering turn into a nightmare of unintended consequences?Explore these possibilities and more in our new exhibition that blurs the lines between fact and fantasy, and art and science.

MIT is not a place so much as it is a unique collection of exceptional people.What is essential at MIT is asking questions others may not ask, trying the unexpected in pursuit of a greater solution, and embracing distinctive skills and combinations of talents. Whether encompassing global issues, ventures into space, or efforts to improve our daily lives, stories told in this exhibit showcase the process of discovery that sits at the heart of MIT.Delve into the experimental culture and collaborative spirit of the MIT community in this dynamic and interactive exploration of groundbreaking projects and ongoing innovation."MIT’s greatest invention may be itself—an unusual concentration of unusual talent, forever reinventing itself on a mission to make a better world." — President L. Rafael ReifLocated in the Brit J. (1961) and Alex (1949) d'Arbeloff GallerySupported by the Biogen Foundation

How can code be used as a creative tool by artists and designers?This question motivates the work of the Future Sketches group at the MIT Media Lab. Led by artist and educator Zach Lieberman, the group aims to help us “see” code by using it to make artistically controlled, computer-generated visuals.Explore some of the latest research from the group that uses typography and digital tools to create interactive, creative, and immersive work.Located in our Martin J. (1959) and Eleanor C. Gruber Gallery.

Experience the captivating work of Arthur Ganson, where his perceptions of the world are choreographed into the subtle movements and gestures of his artistic machines."These machines are daydreams condensed into physical form, computer programs manifesting in three-dimensional space." - Arthur GansonArthur Ganson's medium is a feeling or idea inspired by the world he perceives around him – from the delicate fluttering of paper to the sheer scale of the universe. Combining engineering genius with whimsical choreography, he creates machines to encode those ideas into the physical world. But he invites everyone to draw their own conclusions on the meaning behind the subtle gestures of the machines.Currently on display are a select group of Arthur Ganson's works from our MIT Museum Collection. We expect to exhibit his work in large numbers in the future.

MIT Collects features objects and other media from the museum's vast collection, arranged in areas that tell stories, explore themes, and dive into subject areas.Modeling Everything:Models and model-making, both the objects and the action, are vital to every research area at MIT and to the life of the Institute itself. Explore a wide array of models for teaching, discovery, research, and documentation, from ships to crystal structures to architectural design.Radical Atoms:Hiroshi Ishii and the Tangible Media Group at the MIT Media Lab have pioneered new ways for people to interact with computers, with the invention of the “tangible user interface.” It began with a vision of “Tangible Bits,” where users can manipulate ordinary physical objects to access digital information. It evolved into a bolder vision of “Radical Atoms,” where materials can change form and reconfigure themselves just as pixels can on a screen.This experimental exhibit of three iconic works—SandScape, inFORM, and TRANSFORM—is part of the MIT Museum’s ongoing efforts to collect the physical machines as well as preserve the user experience of, in Ishii’s words, making atoms dance.A Sequence of Actions:Developed and operated at MIT, the Differential Analyzer, Whirlwind Computer, and Apollo Guidance Computer were massive and complex projects that involved thousands of people. See historical components and artifacts from this critical era in programming during the mid-20th century and explore how these early programmers influenced today’s digital culture.Technology and the Dream:Through recordings of students, staff, researchers, and community members, listen to personal reflections and gain a sense of the Black experience at MIT. This dynamic audio installation is co-curated with the MIT Black History Project.Totally Useless Things:Toys, puzzles, and play are a significant part of the creative process. Playful activity can shape a research agenda or an entire discipline. Extracurricular play — like MIT's famous hacks — enhances creativity and community. And play itself is a rich field for scientific research. Jump in and learn how curiosity is the fuel that discovery runs on.Located in the Edward O. Thorp Gallery

How can you investigate something you cannot see?The challenge of understanding the unknown motivates scientists today, just as it has inspired curious people for centuries.Using material from the Allen Forbes Collection, this exhibit traces the scientific process of observing, measuring, and describing that turned whales from monsters into mammals.Using prints from the sixteenth through the nineteenth centuries, Monsters of the Deep examines how European knowledge about the creatures of the sea was informed by new information from sailors, scholars, and beachcombers, and how that knowledge transformed what people understood about the natural world.Want a closer look at what we have on view? You can explore digitized versions of exhibition objects here.On view through January 2026.
