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: Frank Lu (Harvard)Title: Abelian-by-finite families IAbstract:In this talk, we will begin the proof that there are only finitely many rational points whose pre-images along the finite map have large Galois orbits, introduced in the previous talk. The proof of this statement requires two lemmas: a generic simplicity statement, and a finiteness statement if we consider only the rational points corresponding to a given simple Galois representation. We will begin by presenting the proof, assuming these two lemmas, before proving the finiteness lemma.We will follow part of Lawrence and Venkatesh, Diophantine problems and $p$-adic period mappings, Section 6.

Join Félix-Antoine Gélineau, a PhD candidate in Philosophy at the MIT Department of Linguistics and Philosophy, for a conversation around Pedro Gómez-Egaña: The Great Learning.Through the lens of Gómez-Egaña’s The Great Learning, Félix-Antoine Gélineau will examine a question at the confluence of epistemology and the philosophy of art: how does an artwork’s ability to enrich our perspectives relate to its artistic merit? Gélineau will explore how artists, performers—such as the exhibition’s “Orchestrators”—and audiences collaborate in learning and sense-making through art. Along the way, Gélineau will also discuss whether the idea that artistic merit is influenced by what and how we learn from art is compatible with the view that art is valuable for its own sake.About the SpeakerA PhD candidate in philosophy at MIT, Félix-Antoine Gélineau explores questions at the intersection of epistemology, ethics, and meta-ethics. His dissertation starts from the question: in what sense does truth matter? and proceeds to examine how our understanding of the value of truth interacts with our conceptions of the norms we ought to follow when forming and revising our beliefs. Before turning to philosophy, he studied music performance, an experience that sparked a lasting interest in aesthetics and the philosophy of art.Graduate Student TalksMIT graduate students explore current exhibitions at the List Center through the lens of their own research, background, and interests. Join us for this interdisciplinary lecture series where we dive into how art and research are overlapping on MIT’s campus.

Come to the MIT Museum this April as we unravel the mysteries of the deep sea and explore the great unknown.Join artist Keith Ellenbogen for an extraordinary journey beneath the waves as he unveils a window into our local waters through photography.Catch a talk with MIT Professor Julien De Wit on how scientists are searching for signs of oceans (and life!) beyond our solar system.Plunge into the world of aquatic robotics with MIT Sea Grant or experience the dawn of sight as you journey through the ocean's history with the MIT Media Lab's Camera Culture group.Tasty Spanish and Japanese inspired eats from Pagu and local beer from Small Change Brewing Company will be available for purchase.

HOMELESS is a documentary that humanizes unhoused people and explores their backgrounds, dreams and struggles to find the way home. It follows the stories of 5 homeless individuals, who ended up living on the street and losing hope – especially in themselves. In addition, the film includes segments with US president Joe Biden, the mayors of Los Angeles and New York City, the HUD secretary, the FBI director, and prominent homelessness advocates.HOMELESS is not only a documentary, but also a valuable tool in the fight to end homelessness. The United Nations Human Settlements Programme called it "a very powerful documentary," and it will use it to raise awareness for its World Urban Campaign and #HousingMatters Campaign. The film strives to foster empathy and understanding, while also challenging viewers to reconsider how homelessness is perceived and addressed.HOMELESS has garnered support from countless organizations, which are featured in the film through interviews with their representatives: Donald Whitehead Jr (National Coalition for the Homeless), Christine Auclair (World Urban Campaign by UN-Habitat), Catrina Grigsby-Thedford (Nevada Homeless Alliance), Christine Hess (Nevada Housing Coalition), Chris Petersen (ACLU of Nevada), etc.HOMELESS was filmed in Las Vegas because of the city’s contrast between the luxurious casinos and the desolate streets where homeless people struggle to survive. But homelessness is a global challenge: The United Nations Human Settlements Program estimates that 1.6 billion people live in inadequate housing, and the best available data suggests that more than 100 million people have no housing at all.
