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 atrium by the staircase. 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 12, 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.

The Stratton Lecture: The Epidemic of LonelinessDate: Tuesday March 4Time: 12:15pm - 1:45pmLocation: MIT Wong Auditorium (E51-115)Join us for the 2025 Stratton Lecture as we delve into the growing epidemic of loneliness in modern society. Despite unprecedented digital connectivity, many individuals feel isolated and disconnected, with profound impacts on mental and physical health. We’ll explore the societal factors contributing to this phenomenon, the consequences for well-being, and strategies to rebuild authentic connections and stronger communities.Keynote Speaker: Professor Rebecca Saxe Remarks by: Professor Pattie Maes Remarks by: Zan BarryDiscussion Moderated by: Amy Brand, Director and Publisher of MIT PressThis event is co-sponsored by the MIT Retirees Association and MIT Press.A boxed lunch will be provided at the end of the event.

"Supply Shocks and Emissions When Firms Can Adapt" | Silke Forbes (Tufts)

Speaker: Vincent Tournat (CNRS, Le Mans Université / Harvard)Title: Dynamics of multistable mechanical metamaterials: recent results on nonlinear waves, transition fronts and their interactionsAbstract:The class of flexible mechanical metamaterials, which encompasses architected materials composed of highly compliant parts connecting much stiffer and heavier parts, has recently been systematically explored thanks to emerging techniques for their realization and accurate lumped-parameter models describing their dynamics. Examples of such metamaterials include kirigami, origami, elastic lattices with various topologies composed of rotating mass units connected by thin, flexible hinges, or systems of coupled buckled beams… These metamaterials can undergo large deformations and are known to support a wide variety of nonlinear waves, such as vector solitons, breathers, cnoidal waves, among others. Interestingly, by designing these materials with multistable inclusions, such as elastically coupled bistable mechanical units, we can observe phenomena such as transition waves. The transition wave presents itself as a progressive front travelling through the material as the multistable units sequentially switch from one equilibrium state to another, eventually leading to a partial or full reconfiguration of the structure.In this talk, I will highlight the fundamentals and a selection of recent results on nonlinear waves in flexible mechanical metamaterials and in particular transition waves in multistable metamaterials. Through theoretical, numerical and experimental examples, I will discuss some salient properties of these nonlinear waves and their interactions. While in the case of zero damping we find the wave dynamics generally obey the nonlinear KleinGordon equations, the presence of a significant nonzero damping heavily influences the multistable response and permits transition fronts that result from nonlinear reactiondiffusion equations. This class of flexible metamaterials thus gives rise to the emergence of specific properties not necessarily found in other waves supported by discrete and/or nonlinear media, and which can be rationally harnessed, e.g., strong non-reciprocity, robustness of the wave profile, extreme amplitude-dependent behavior… These metamaterials and their dynamics can therefore be designed and implemented for applications involving the local or global reconfiguration of a medium, the manipulation of a mechanical memory, the control of waves in space and time, mechanical computing and more generally to be the vector for embedded material intelligence.
