In celebration of the MIT 24-Hour Challenge, the MIT Alumni Association is hosting a Pre-Pi Day event in Lobby 10 from 11:00 a.m. to 2:00 p.m. This Pre-Pi Day gathering encourages students to reflect on the impact of alumni on their experience, to engage with the MIT Alumni Association before joining the alumni community, and to philanthropically support the Institute. Stop by Lobby 10 from 11:00 a.m. to 2:00 p.m. for games, pizza, and a fun Pi recitation that will entertain and bring together the MIT community!

From controlling prosthetics to automating smart homes, gesture-based human-machine interfaces have the potential to revolutionize how we interact with technology. While gesture-based solutions based on internal electrical responses, computer vision, and motion-tracking have demonstrated promise in specific applications, they may be hindered by limitations such as environmental noise, privacy concerns, and a lack of haptic feedback. Faye Wu of Manus Robotics will discuss these challenges and explore emerging technologies for intuitive gesture-based device interactions.Register for this MIT Horizon webinar.This is a series of live events in partnership with MIT Startup Exchange.

On December 3, 2024, South Korean President Yoon Suk-yeol shocked the world by declaring martial law. How could a thriving democracy backslide so quickly? This crisis reveals a deeper issue: the impact of nationalist polarization—when political parties are divided by conflicting nationalist visions. This type of polarization is especially harmful because it undermines the foundations of democracy. In countries with histories of nationalist conflict, like South Korea and the United States, nationalist polarization becomes a persistent barrier, limiting how strong and stable democracy can be.Aram Hur is Assistant Professor of Political Science and the Kim Koo Chair in Korean Studies at the Fletcher School of Law & Diplomacy, Tufts University. She is a scholar of nationalism and democracy. Her book, Narratives of Civic Duty: How National Stories Shape Democracy in Asia (Cornell University Press, 2022), is the winner of the 2023 Robert A. Dahl Award for “scholarship of the highest quality on the subject of democracy” from the American Political Science Association.This is part of CIS's Global Research & Policy Seminar series.Lunch will be available at 11:45am.

In this Leading Edge Webinar, we explore sustainable versions of two of the most prevalent, yet sometimes overlooked materials in our modern daily life: polymers and concrete. Polymers are as ubiquitous as plastics and have wide applications in packaging, car parts, medical products, electronics, glues/paints/coatings/lubricants, and countless other industries. Yet, they can be tough on the environment because they are not always quickly or safely biodegradable. Likewise, concrete has been used for millennia in construction, but producing it can produce huge amounts of globally warming carbon dioxide (CO2).What if we could make these two everyday materials more sustainable? What might sustainable polymers look like, and how can we efficiently search for sustainable polymers among a myriad of potential candidates? Likewise - can we make concrete do more than just serve as a structural material – is it possible to store carbon dioxide, sequester it in concrete itself to offset its carbon footprint – or even store energy – in ordinary buildings and pavements?Join Prof. Bradley Olsen of MIT’s Chemical Engineering Department, and Prof. Admir Masic of MIT’s Civil and Environmental Engineering Department, as they investigate these possibilities.

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 lobby with the big mirror, right inside the Collier Memorial entrance to Stata. 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 28, 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.
