A celebration of creativity and community at MITArtfinity is a new festival of the arts at MIT featuring 80 free performing and visual arts events, celebrating creativity and community at the Institute. Artfinity launches with the opening of the new Edward and Joyce Linde Music Building on February 15, 2025, continues with a concentration of events February 28-March 16, and culminates with the Eugene McDermott Award in the Arts public lecture by 2025 recipient artist and designer Es Devlin on May 1, 2025, and a concert by Grammy-winning rapper and Visiting Professor Lupe Fiasco on May 2, 2025. Artfinity embodies MIT’s commitment to creativity, community, and the intersection of art, science and technology. We invite you to join us in this celebration, explore the diverse events, and experience the innovative spirit that defines the arts at MIT.About the Artists Artfinity features the innovative work of MIT faculty, students, staff, and alumni, alongside guest artists from the Greater Boston area and beyond.About the Activities & Events All 80 events are open to the public, including dozens of concerts and performances plus an array of visual arts such as projections, films, installations, exhibitions, and augmented reality experiences, as well as lectures and workshops for attendees to participate in. With a wide range of visual and performing arts events open to all, Artfinity embodies MIT’s commitment to the arts and the intersection of art, science, and technology.About the Presenters Artfinity is an institute-sponsored event organized by the Office of the Arts at MIT with faculty leads Institute Professor of Music Marcus Thompson and Professor of Art, Culture and Technology Azra Akšamija. Departments, labs, centers, and student groups across MIT are presenting partners.Visit arts.mit.edu for more information about the arts at MIT.

Writing Together Online offers structured time to help you spring into writing and stay focused this semester. We offer writing sessions every workday, Monday through Friday.

Speaker: Alex Lubotzky (Weizmann Institute & the Hebrew University, Simons Distinguished Visiting Professor, MIT)Title: High Dimensional Expanders (HDX) and their applications in pure math and computer scienceAbstract:Expander graphs have been an intensive topic of research in math and CS during the last six decades. In the last two decades a high dimensional theory has emerged with (very different) applications in math & CS.In this series of 8 independent (but related) lectures we present some aspects of the theory of HDX and its applications, a number of open problems and suggestions for further research.A more detailed plan:1. Thursday 2/20/25, 4:30pm, 2-190 (Math Colloquium); refreshments served at 4pm in 2-290  Introduction: three main problems(a) Gromov overlapping property(b) Locally testable codes(c) Are all groups sofic?2. Tuesday 2/25/25, 4:15-5:15pm, 32-G449 (Theory of Computing Colloquium), refreshments served at 4pmGood Locally testable codes3. Wednesday 2/26/25, 9:30-11am, 2-449Expander graphs: combinatorics, spectral gap, representation theory(Kazhdan property (T), property (\tau) and more) and property testing4. Wednesday 3/5/25, 9:30-11am, 2-449Geometric & topological expanders, Coboundary expanders, Random simplicial complexes and Property testing5. Wednesday 3/12/25, 9:30-11am, 2-449From Ramanujan graphs to Ramanujan complexes6. Wednesday 3/19/25, 9:30-11am, 2-449Stability and group approximation, Garland Theorem and the p-adic Deligne central extensionsWednesday 3/26/25 - Spring vacation7. Wednesday 4/2/26, 9:30-11am, 2-449Some more CS: Agreement tests, direct product test; PCP8. Wednesday 4/9/25, 9:30-11am, 2-449Are there non-sofic groups? The Aldous-Lyons conjecture and more

Hidden within MIT’s Distinctive Collections, many architectural elements from the earliest days of the Institute’s architecture program still survive as part of the Rotch Art Collection. Among the artworks that conservators salvaged was a set of striking windows of gypsum and stained-glass, dating to the late 18th- to 19th c. Ottoman Empire. This exhibition illuminates the life of these historic windows, tracing their refracted histories from Egypt to MIT, their ongoing conservation, and the cutting-edge research they still prompt.The Maihaugen Gallery (14N-130) is open Monday through Thursday, 10am - 4pm, excluding Institute holidays.

Time: 10:00 AM/6:00 PMLocation: Greensboro, NC
