Have some fun(nel) on a tunnel or sun(nel) walk! Join us for a 30-minute volunteer-led walk either through MIT's famous tunnel system or around Killian Court. As the weather gets warmer, walk leaders may choose to take the group outside. Is the weather warm and you missed the start? Find the group on Killian Court and join in!Location details: Meet in the lobby under the “Belonging + Community” banner. Location photo below.Sun(nel) Walk Leaders will identify themselves by holding a white at the meeting location.Prize Drawing: Attend a walk and scan a QR code from the walk leaders to be entered into a drawing for a getfit canvas boat tote bag at the end of the getfit challenge. The more walks you attend, the more entries you get. Winner will be drawn and notified at the end of April. Winner does not need to be a getfit participant.Disclaimer: Tunnel walks are led by volunteers. In the rare occasion when a volunteer isn’t able to make it, we will do our best to notify participants. In the event we are unable to notify participants and a walk leader does not show up, we encourage you to walk as much as you feel comfortable doing so. We recommend you check this calendar just before you head out!Getfit is a 12-week fitness challenge for the entire MIT community. These tunnel walks are open to the entire MIT community and you do not need to be a current getfit participant to join.

Speaker: Dun Tang (University of California, Berkeley)Title: A Dijkgraff-Witten type reconstruction formula for g=1 quantum Κ-invariantsAbstract: Quantum Κ-invariants are defined as holomorphic Euler characteristics on the moduli space of stable maps, incorporating products of universal cotangent bundles and virtual bundles pulled back from the target space. These invariants enumerate the dimensions of sheaf cohomology. In this talk, I will present a reconstruction formula for general genus-one quantum Κ-invariants, expressing them in terms of genus-zero invariants and genus-one invariants with at most one marked point carrying a universal cotangent line bundle.

Mark your calendars! Join us on Thursday, April 24 at 4pm in room 6-120 for the third seminar in the Colloquium Series: Research on the Mind featuring keynote speaker Luana Marques, PhD, who will be presenting “Bold Move: How to Thrive Through Uncertainty”. Dr. Marques is a global speaker, author, scientist, and innovator, currently an Associate Professor at Harvard Medical School. She’s the former President of the Anxiety & Depression Association of America and the Founder & Director of Community Psychiatry PRIDE, a premier research lab at Massachusetts General Hospital. Check out one of her talks: Here. To learn more about Dr. Marques, visit: https://drluana.com/.This event is open to everyone, and we encourage all to attend! Light refreshments will be served before the event (~3:40pm).

Recreational swims provide a fun and engaging way for children and parents to practice new skills, stay active, and enjoy quality time together in the pool with the MIT community.No Z Center (MIT Recreation - Zesiger Sports and Fitness Center) membership is required to participate.A parent or caregiver must accompany children in the water. Per Z Center policy, each adult may supervise up to two children at a time.Children must be at least 6 months old to join. If younger, they must be able to hold their head up comfortably.
