As part of MIT's Day of Climate, this professional development session provides training for Coastal Climate Science Activities and Experiments.Increased CO2 in the atmosphere is impacting coastal environments with adverse effects such as sea level rise, damage to marine life, and extreme weather. This project will present an overall framework that illustrates how increased CO2 is causing changes in water quality including acidification, temperature, salinity, dissolved oxygen, and others.Students will derive the connections by means of experiments and text investigations then place them in the overall framework, creating the big picture for themselves. This curriculum, building on the work from Sea Perch II, aims to foster climate science knowledge and scientific practices, empowering students to understand and act on climate-related issues.Register for this in-person session.

Participants will step into the shoes of a neuroscientist and explore the tools and techniques doctors use to diagnose and study our body's most complex organs.$15 for ages 11-18, $20 for ages 19+

Speaker: Juan Muñoz-Echániz (Stony Brook University)Title: Boundary Dehn twists on symplectic 4-manifold with Seifert-fibered boundaryAbstract: In this talk I will discuss the following result: the boundary Dehn twist on a symplectic filling M of a Seifert-fibered rational homology 3-sphere (negatively-oriented, equipped with its canonical contact structure) has infinite order in the smooth mapping class group of $M$ (fixing the boundary) provided $b^+ (M) > 0$. This result has applications to the monodromy of surface singularities, such as: the monodromy diffeomorphism of a weighted-homogeneous isolated hypersurface singularity of complex dimension 2 has infinite order in the smooth mapping class group of its Milnor fiber, provided the singularity is not ADE. (In turn, the ADE singularities have finite order monodromy by Brieskorn’s Simultaneous Resolution Theorem.)The proof involves studying the Seiberg—Witten equation in 1-parametric families of 4-manifolds, by a combination of techniques from Floer homology, symplectic and contact geometry. I will also explain how to use our techniques to obstruct boundary Dehn twists from factorising as products of Seidel—Dehn twists on Lagrangian 2-spheres and/or their squares, in both the smooth and/or symplectic mapping class groups.This is based on joint work with Hokuto Konno, Jianfeng Lin and Anubhav Mukherjee.
