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 with the big mirror, right inside the Collier Memorial entrance to Stata. Location photo below.Sun(nel) Walk Leaders will identify themselves by holding a white flag 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: These 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!Getfit is a 12-week fitness challenge for the entire MIT community. These walks are open to the entire MIT community and you do not need to be a current getfit participant to join.

Speaker: Zijie Zhuang (UPenn)Title: Percolation of thick points of the log-correlated Gaussian field in high dimensionsAbstract:The log-correlated Gaussian field is the higher-dimensional analog of the 2D Gaussian free field. In this talk, I will present a result showing that the set of thick points of the log-correlated Gaussian field contains an unbounded path in high dimensions. I will discuss how we get intuition from fractal percolation and the application to the exponential metric of the log-correlated Gaussian field. Based on joint work with Jian Ding and Ewain Gwynne.
