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: Denis Bernard (CMSA, Harvard, and Ecole Normale Supérieure de Paris)In person or on Zoom: https://mit.zoom.us/j/92441268505Title: A group theory perspective on quantum exclusion processesAbstract: Exclusion processes are stochastic particle lattice systems modeling fluctuations in classical diffusive systems. Their extensive study over the past decades led to the formulation of the now called macroscopic fluctuation theory - a framework extending Bolztman's theory to non-equilibrium diffusive systems. In the first part of the talk, I will describe the newly proposed quantum extension of exclusion processes, aiming at formulating a quantum version of the macroscopic fluctuation theory. The focus will be on the interplay between group theory and probability theory at play in solving these models. In the second part, I will describe elements of a theory of structured random matrices which has emerged from studying these models.

Presented by the Emerson/Harris Program for Private Study Solo Recital SeriesProgramTBDLivestream: https://mta.mit.edu/viewlisten/live-killian-hallAbout the PerformersJustin Yamaguchi is an 18-year-old violinist, pianist, and composer. Currently a freshman at MIT, he intends on majoring in mathematics and computer science, as well as minoring in music. Justin currently studies violin with Lynn Chang through the Emerson-Harris Scholars program and has studied with Peter Zazofsky (BU) previously. Developing his love for music from a young age, he began piano lessons at age five, took up the violin at six, and started composing music by age ten. Justin’s dedication has won him various accolades across these disciplines. Over the years, he has been the state winner of the Music Teacher National Association (MTNA) Composition Competition multiple times. As a pianist, he has won top prizes at the Bay State and Steinway Piano Competitions; as a violinist, he was named a National YoungArts Winner. Justin has served as concertmaster of the Boston Youth Symphony Orchestras senior orchestra. He has also participated in the Massachusetts Music Educators Association (MMEA) All-State Orchestra and the Harvard-Radcliffe Orchestra. During the summer, Justin has attended various festivals, including Berkshire High Peaks Festival and Boston University Tanglewood Institute’s String Quartet workshop. He attended the Roxbury Latin School, where he was a key leader in its chamber music program. At MIT, he has contributed to MIT's newest ensemble, AXIOM Chamber Orchestra, in addition to playing chamber music as part of Chamber Music Society. In his free time, he enjoys spending time with friends and family.About the Emerson/Harris Program for Private StudySupport for private musical study is available for students through the Emerson/Harris Program (E/HP), which offers merit-based financial awards for outstanding achievement on instruments or voice in classical, jazz, or world music. Each academic year, the program awards Scholarships and Fellowships to nearly seventy students who commit to a full year’s study and participate in the musical life of MIT.Auditions for the program are held at the beginning of each academic year. Private teacher selections, made in consultation with the E/HP jury heads, may include instructors from MIT staff and throughout Greater Boston. The Emerson/Harris Program is funded by the late Mr. Cherry L. Emerson, Jr. (SM, 1941), in response to an appeal from AssociateProvost Ellen T. Harris (Class of 1949 Professor Emeritus of Music). The Emerson/Harris Masterclass Series is supported, in part, by the Robert L. Malster (1956) Fund.This project is presented as part of Artfinity, an Institute-sponsored event celebrating creativity and community at MIT. Artfinity is organized by the Office of the Arts.
