Stop by for snacks and tea with the SHASS community, students, and instructors!HumaniTea is a program partnering with other units in SHASS to gather, share some food and thought, and enrich our shared MIT experience in the process. Once a month, SHASS community members, instructors, and students from diverse fields of studies, backgrounds, and interests can stop in and enjoy a cup of tea or snack.Monday, February 24 Monday, March 17 Monday, April 7 Monday, May 5@ 4:15 – 5:45PM Building 14E-304**Directions: Third floor of Building 14 from the Lewis Music Library stairs, through the CMS/W doors. Alternatively, take the elevator to the 3rd floor and navigate to the opposite end of the hallway, through third floor and CMS/W doors!Sign up for HumaniTea info: bit.ly/mithumanitea

Speaker: Ben Knudsen (Northeastern University)Title: Probabilistic invariants of finite groupsAbstract: We continue the study of the probabilistic versions of the Lusternik–Schnirelmann category and topological complexity introduced in joint work with Weinberger and independently by Dranishnikov–Jauhari. In the aspherical context, where these invariants are group invariants, there is a universal upper bound in the finite case. We discuss progress toward calculating the exact value, which is equivalent to an interesting problem in equivariant homotopy theory. This talk is based on joint work with Shmuel Weinberger.

The MIT wrestling club holds practices in the du Pont Wrestling Room on weeknights 5:30-7pm. All levels of experience welcome! Whether you're looking to learn how to grapple or just want to get in a good workout, wrestling practice is a good time to learn technique, get in some live goes, and have fun with a great group of people.Current schedule is: structured practice MTRF, open mats W, and technique sessions 9-10:30am on Saturday. For more information, contact wrestling-officers@mit.edu.
