Speaker: Yair Shenfeld (Brown University)Title: The Brownian and Poisson transport mapsAbstract:Transport maps serve as a powerful tool to transfer information from source to target measures. However, this transfer of information is possible only if the transport map is sufficiently regular, which is often difficult to show. I will explain how taking the source measure to be an infinite-dimensional measure, and building transport maps based on stochastic processes, solves some of these challenges both in the continuous and discrete settings.*Note change in date/location.

Speaker: Nick Early - IASTitle: Combinatorial Adventures in Configuration SpaceAbstract: In recent years, a surge of activity has uncovered deep connections between combinatorics, algebraic and tropical geometry, and scattering amplitudes in quantum field theory (QFT). In this talk, I will explain how these ideas naturally build on one another, unveiling new results and open problems in geometric combinatorics. Along the way, I will highlight several rich combinatorial structures that arise, involving the positive Grassmannian and configuration space, matroid subdivisions, and tropical hyperplane arrangements.

As part of MIT's Day of Climate, this professional development session provides training for the Climate Change Charades activity.Focused on elementary school-aged learners, climate change charades will address the gap in accessible, engaging, and interactive climate education.Learners act out or describe climate change-related concepts, helping to reinforce their understanding in a fun, collaborative way. Inspired by Climate Fresk workshops, which break down the complexities of the Intergovernmental Panel on Climate Change reports, this activity will utilize a similar concept to make learning about climate change more accessible.By acting out different environmental and climate phenomena, students will deepen their comprehension of key climate concepts while also building communication and teamwork skills. The interactive play allows for the responsible introduction of potentially climate-anxiety inducing topics to impressionable ages. This game can be used as an icebreaker, an introduction to more advanced topics, or a way to reinforce content already covered in class.Register for this in-person session.

Time: 4:00 PMLocation: Beverly, MA

Every Wednesday night you are invited to come to The Table for peaceful Christian worship in the Chapel at 5:15 pm and dinner in the Main Dining Room of W11 at 6:30 pm.We worship with beautiful songs, open conversation about the Scriptures, prayers and a simple sharing of communion around the altar. Then we enjoy dinner together and good company together. Whether you come every week or just drop by once in a while, there is a caring community for you at the Table.You are truly welcome to come as you are: undergrad, grad, or post-doc; sure of your faith or wondering what it is all about; gay, straight, bi, trans*, questioning. Please join us for no-pressure worship and fellowship.Hosted by the Lutheran Epsicopal Ministry @ MIT. For more information, or to verify gathering times during holiday and vacation periods, please contact chaplains Andrew Heisen (heisen@mit.edu) and Kevin Vetiac (kvet246@mit.edu).
