High-performance reusable rocket engines recently developed by SpaceX and Blue Origin, and newer ones in development for low-cost heavy-lift launch vehicles, will enable next-generation space economics and accessibility. This talk will describe the work of MIT AeroAstro’s Zachary Cordero and his group along these lines, leveraging modern materials design, advanced manufacturing, and computational design tools to develop and manufacture the specialized materials that will power the future of spaceflight.

Speaker: Michal Shavit (NYU)Title: Weak turbulence of 2D internal gravity wavesAbstract:Our work addresses a long-standing problem: describing internal wave turbulence in the ocean from the governing equations. A promising avenue lies in the kinetic approach. But the stratified Euler equations form an anisotropic, non-canonical Hamiltonian system, making the classical wave-turbulence approach inapplicable. We take a new route: studying the singular limit of vanishing rotation, where rotation acts as a regulator near the curve of zero-frequency slow modes. This regime is both mathematically tractable and oceanographically relevant. In this limit, we derive the turbulent spectrum of 2D weakly interacting internal gravity waves, which matches the celebrated Garrett–Munk spectrum known from observations, for the first time from first principles.

As a graduate student or postdoc, you will continue to advance in your teaching practice, particularly if you intend to pursue a career in academia. Your role as an educator can seem to take quantum leaps, from grading problem sets and papers to running recitations, taking responsibility for an entire class or section, and eventually advancing to instructor of record as you begin to teach classes of your own design. This compound workshop and panel event will help you to place these transitions within a developmental perspective that focuses on your own learning as an emerging educator.Registration is required for this event.

Speaker: Christopher Hacon (University of Utah)Title: The cone theorem for Kähler varietiesAbstract:There has been substantial recent progress towards the minimal model program for Kähler varieties. In this talk I will discuss a recent proof of the Cone Theorem for Kähler varieties of arbitrary dimension and related results such as the canonical bundle formula, subadjunction and Wenhao Ou's recent breakthrough result on the characterization of uniruled compact Kähler manifolds.

You’re invited to a special Open Access Week event to highlight the value of open data at MIT and to celebrate the winners of the 2025 MIT Prize for Open Data. The program will feature short talks from prize winners about their research. After the program, enjoy a reception featuring refreshments and an opportunity to meet the winners, honorable mention recipients, and other open data advocates and practitioners from across campus.RegisterCo-sponsored by the MIT School of Science and the MIT Libraries
