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 12, 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: Andrew Riesen (MIT)In person or on Zoom: https://mit.zoom.us/j/92441268505Title: Orbifolds of Pointed Vertex AlgebrasAbstract: This talk is based on joint work with Terry Gannon. We will discuss the interplay of tensor categories $\mathcal{C}$ with some group action $G$ and orbifolds $\mathcal{V}^G$ of vertex operator algebras $\mathcal{V}$ (VOAs for short). More specifically, we will show how the categorical structure of $\mathrm{TwMod}_G \mathcal{V}$ allows one to not only simplify previous results done purely through VOA techniques but vastly extend them. One such example is the Dijkgraaf-Witten conjecture, now a theorem, which describes how the category of modules of a holomorphic orbifold should look like. Additionally, our techniques also allow us to expand the modular fusion categories known to arise from VOAs, we show that every group-theoretical fusion category comes from a VOA orbifold. Lastly, we will discuss how VOAs with group actions give concrete realizations of $G$-Tambara Yamagami categories for nilpotent $G$.

Please join MIT Anthropology Professor Sonya Atalay (NSF CBIKS founder & director) for the first Indigenous Sciences Speaker Series speaker of 2025.This talk shares insights from a collaborative field school bringing together students and Tribal members from the Amah Mutsun Tribal Band and their Land Trust. Informed by cultural perspectives and priorities, participants learned archaeological field methods developed by the Tribe and archaeologists over the last decade to study and preserve Indigenous cultural heritage.The U.S. National Science Foundation Center for Braiding Indigenous Knowledges and Science (NSF CBIKS) invites you to the third speaker in the Indigenous Sciences Speaker Series: Dr. Gabe Sanchez. Gabriel Sanchez is an Indigenous Anthropologist and Assistant Professor in the Department of Anthropology and Native American and Indigenous Studies at the University of Oregon (UO). Gabriel currently participates in collaborative and community-based participatory research projects with the Amah Mutsun Tribal Band, the Esselen Tribe of Monterey County, and California State Parks, to investigate the native range of California’s endangered salmon species, which are vulnerable to extinction or extirpation. Collaborative research is a relatively niche but growing component of archaeological practice. While academic institutions and professional societies highlight the importance of Indigenous, collaborative, and decolonizing research strategies, opportunities to train students in these techniques are still generally lacking. This talk shares insights from a collaborative field school bringing together students and Tribal members from the Amah Mutsun Tribal Band and their Land Trust. Informed by cultural perspectives and priorities, participants learned archaeological field methods developed by the Tribe and archaeologists over the last decade to study and preserve Indigenous cultural heritage. In this talk, I consider how Indigenous-led efforts in central coastal California archaeology, focusing on site stewardship, access, research, and education, can broadly benefit field schools. Join us in welcoming Dr. Sanchez to our community and enjoy an engaging presentation and Q&A.
