Want to get exercise mid-day but don’t want to go outside? Join the tunnel walk for a 30-minute walk led by a volunteer through MIT’s famous tunnel system. This walk may include stairs/inclines. Wear comfortable shoes. Free.Location details: Meet in the atrium by the staircase. Location photo below.Tunnel Walk Leaders will have a white flag they will raise at the meeting spot for you to find them.Prize Drawing: Attend a walk and scan a QR code from the walk leaders to be entered into a drawing for a getfit 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 checking this calendar just before you head out. [As of Feb 7, this calendar is defaulting to the year 1899. Click "today" to be brought to the current month.]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: Griffin Wang (IAS)Title: Tetrahedral Symbol and Relative Langlands DualityAbstract: In the quantum theory of angular momentum, the Racah--Wigner coefficient, often known as the 6-j symbol, is a numerical invariant assigned to a tetrahedron with half-integer edge-lengths. The 6 edge-lengths may be viewed as representations of SU(2) satisfying certain multiplicity-one conditions. One important property of the 6j symbol is its hidden symmetry outside the tetrahedral ones, originally discovered by Regge.In this talk, we explore a generalized construction, dubbed tetrahedral symbol, in the context of rank-1 semisimple groups over local fields, and explain how the extra symmetries may be explained by relative Langlands duality. Joint work with Akshay Venkatesh.

Join us for an engaging introductory session on MIT’s Day of Climate!Discover how you can actively participate in climate education and action. During this session, you'll learn about the vision behind the Day of Climate, get an overview of the curriculum activities and professional development activities, and discuss with peers what it means to be involved in climate action. In collaboration with MIT’s Systems Awareness Lab, this session will provide valuable insights into the social-emotional and systems-thinking aspects of climate education. You'll engage in reflective exercises, participate in dynamic discussions, and connect with a network of educators, researchers, students, and community members passionate about climate solutions.Register for the webinar.
