On view October 1 -- December 11, 2025This exhibition draws on archival materials from the Aga Khan Documentation Center at MIT (AKDC) to explore a century of cultural heritage preservation in Aleppo, Syria. It takes as its point of departure the work of Kamil al-Ghazzi (1853–1933), the pioneering Aleppine historian whose influential three-volume chronicle, Nahr al-Dhahab fī Tārīkh Ḥalab (The River of Gold in the History of Aleppo), was published between 1924 and 1926.Ink, Stone, and Silver Light presents three modes of documentation—manuscript, built form, and photography—through which Aleppo’s urban memory has been recorded and preserved. Featuring figures such as Michel Écochard and Yasser Tabbaa alongside al-Ghazzi, the exhibition traces overlapping efforts to capture the spirit of a city shaped by commerce, craft, and coexistence. At a time when Syria again confronts upheaval and displacement, these archival fragments offer models for preserving the past while envisioning futures rooted in dignity, knowledge, and place.

Join us for a timely debriefing on the outcomes of COP30 in Belém, Brazil, a pivotal moment marking the 10th anniversary of the Paris Agreement. As the world reflects on a decade of progress and persistent challenges in global climate governance, this discussion will unpack key decisions from COP30, assess their implications for international cooperation, climate finance, and adaptation, and explore how major actors—including rising powers — are shaping the path forward. The event will bring together MIT climate experts to assess where we stand today, reflect on lessons from the past decade, and identify priorities for the next phase of climate action.This seminar will be held in 10-105 (Bush Room). Lunch will be available. Please RSVP here.Contact Kate Danahy at kdanahy@mit.edu with any questions.This event is part of the CIS Global Research & Policy Seminar Series. Join our mailing list here to learn about upcoming seminars in the series.

Come by for snacks, and tea with Literature Section friends, instructors, students, etc. What are you reading? What 21L classes are you taking or hoping to take? This event is specifically geared towards undergrads; but open to friends of the community that engage in the literary and humanities at MIT.

Speaker: Daniel Spiegel (Harvard Univesity)Title: A Classifying Space for Phases of Matrix Product StatesAbstract: Alexei Kitaev has conjectured that there should be a loop spectrum consist- ing of spaces of gapped invertible quantum spin systems, indexed by spatial dimension 𝑑 of the lattice. Motivated by Kitaev’s conjecture, I will detail a concrete construction of a topological space 𝐵 consisting of translation in- variant injective matrix product states (MPS) of all physical and bond di- mensions, which plays the role of Kitaev’s space in dimension 𝑑 = 1. Hav- ing such a space is a useful tool in the discussion of parametrized phases of MPS; in fact, it allows us to define a parametrized phase as a homotopy class of maps into 𝐵.The space 𝐵 is constructed as the quotient of a contractible space 𝐸 of MPS tensors modulo gauge transformations. The projection map from 𝐸 to 𝐵 is a quasifibration, from which we can compute the homotopy groups of the classifying space 𝐵 by a long exact sequence. In particular, 𝐵 has the weak homotopy type 𝐾(ℤ, 2) × 𝐾(ℤ, 3), shedding light on Kitaev’s conjecture in the context of MPS.
