As it does each year, Radius will co-sponsor this important annual event with Massachusetts Peace Action.From MAPA:The threat of nuclear war is increasing, rather than abating.Biden's recent actions in the Russia/Ukraine conflict has sharply increased the danger.The tragic Israel/Gaza conflict continues to expand.Cold Warriors in high places are beating the drums of war toward Russia and China.Enormous public expenditures are being made on upgrading all three legs of the nuclear weapons triadResponding to these costs and dangers, we will meet virtually to call for Reducing Congressional Spending for Nuclear Weapons and discuss how to organize to meet the challenge.

In this activity each student will learn about the design and construction of a mechanical watch. The student will take apart a watch movement and put it back together, with instruction from Jason Champion (instructor from the AWCI: American Watchmakers and Clockmakers Institute), with help from Jack Kurdzionak and Steve Boynton (professional watchmakers), and Prof. Gerry Sussman (an amateur watchmaker). The entire exercise will take 4 hours. Each session will be limited to 8 students. Students need no prior experience, and all tools and materials will be provided by the instructors, as needed.Enrollment is limited. You must sign up for one of the 4-hour sessions:Saturday, 25 January 2025, 9am-1pmSaturday, 25 January 2025, 2:30pm-6:30pmSunday, 26 January 2025, 9am-1pmSunday, 26 January 2025, 2:30pm-6:30pmRegistration is now closed. If you wish to be added to the waitlist for one of the sessions, please email Cindy Rosenthal (crosenth@mit.edu).As part of this activity Professor Sussman will give a lecture on the theory of the mechanical watch and its relationship to an electronic impulse-driven oscillator. There will be a discussion of friction (resistance) and its effect on Q and timing precision. The lecture will explain why it is essential for the impulse to be supplied to the oscillator at the zero crossings of the angle, and why the oscillator will enter a limit cycle of a known amplitude.The lecture is open to the MIT community. It will be from 11:30am-12:30pm, in 34-101 on Friday, 24 January.

Welcome to our first social event of 2025!This event comes exactly one month after Christmas and 20 days after Spain’s traditional celebration of the Three Wise Men. To keep the festive spirit alive, we’ll be decorating individual roscones de reyes!Here’s what to expect:Each attendee will receive an individual roscón.Decorating materials will be provided, but feel free to bring your own (including scissors) to personalize your creation with any theme you like.Prizes will be awarded for the three best-decorated roscones!When: Saturday, January 25, 3:30 – 6:30 PM Where: Student Center (Bldg. W20), Multipurpose Room 401 (W20-401)This event is a perfect opportunity to reconnect, share IAP experiences, and enjoy a warm welcome back to campus after the winter break.Please RSVP below if you plan to attend!https://docs.google.com/forms/d/1kaaoBloT8I9I_jrFUYtU8i_eCowc1nUagFj2Zg6zwn8/edit

Kick off the new year by learning a new style of latin dance: Cuban casino.What is casino? It’s a style of partner dance (with a lead and follow) that originated in Cuba in the 1950s. It can be danced with a partner, or in a big circle called a “rueda”. Casino is similar to salsa, and is often called “Cuban salsa”, though there are important differences that we can discuss during the course. Here’s an example: https://www.youtube.com/watch?v=HoulZ35X6RIWhat to expectThis course is intended to take you from being an absolute beginner to having the skills and confidence to go out there and have an enjoyable dance with a stranger in a social setting. We’ll heavily focus on technique, so you’re likely to learn something even if you already have experience with rueda de casino or even casino itself. The course is also focused on partner dancing, not rueda.No prior experience necessary. No partner necessary. Open to everyone.Because each class builds on the previous one, we strongly encourage attendance to all sessions.Who’s teaching?The class will be led by MIT alum Rodrigo (myself) and Diana Ruiz. We’ve both been dancing and teaching in San Francisco and/or Boston for 10+ years.Location and TimeClasses will be on Saturdays during IAP from 5pm-6:30pm at the Student Center (W20-491).How to join?Please fill out this form: https://forms.gle/oWYh6HdtqkRRPMXQAQuestions?
