What is holography? It's not just beautiful art – it's also a range of measurement techniques that let you record a 3D light field. Come learn the theory of wave optics, interference, and diffraction, and then make your own holograms in our hands-on lab! See what your favorite image looks like when turned into a computer-generated hologram. We'll also do demos and visit the newly renovated MIT Museum, home of the world's most comprehensive collection of holographic art. No prior background required. Must register by 12/20/2024Dates: Jan 7th, 9th, 12th, 14th, 16th (M, W, F) 10 AM–NoonTime: 10AM - 12PM ESTLocation: MIT Beaver Works - 300 Technology Square, Suite 200Registration Opens: October 27 1, 2025To register email: holography@ll.mit.edu. Limit 30 students. NOTE: All 6 class sessions are required.

In this IAP series, you will learn how to design, test, and iterate your own puzzle box while exploring what makes puzzles fun, challenging, frustrating, and/or rewarding. No previous experience with puzzles, engineering, or modeling is needed. We will provide supplies for prototyping and an introduction to digital prototyping.Registration will be capped at 15 participants. Please only RSVP if you plan on attending most of the sessions.Series Schedule (Subject to Modification)In-Person Sessions are 10am-11:30amOnline sessions are 10am-11amWeek 1Monday 1/5: In-PersonExplore a variety of puzzle boxes while exploring goals, challenge level, and design decisionsBegin to brainstorm and outline ideas for your own puzzle boxTuesday 1/6: VirtualShare and discuss initial design ideasExplore common mechanisms, signposting, and how to systematically add complexityWednesday 1/7: VirtualBegin prototyping puzzle boxes and experimenting with mechanismsExplore how to effectively user-testThursday 1/8: ZoomIntroduction to designing puzzles digitallyFriday 1/9: In-PersonBuild and feedback sessionWeek 2Wednesday 1/14: VirtualDesign check-in (Note time of this session may change)Week 3Wednesday 1/21: In-PersonTesting and iterationFriday 1/23Present and play test your puzzles

It's a good time to get creative and finish that project! The Fiber Crafts Group offers the space to craft online with friends. Meetings will be held via Zoom. Feel free to sign in at any time over the session, and stay for as long as you like. For a Zoom invite, please email Olimpia Caceres-Brown (olimpia@mit.edu)

Curious about how supercomputers work?Ever wanted to run your own mini supercomputer? In this hands-on IAP course, you’ll design and build a working supercomputing cluster using Raspberry Pi components. Learn how to:Assemble and network your own Pi clusterInstall a supercomputing software stack and cluster management toolsDeploy scientific and data analysis applicationsRun scaled-down versions of real high-performance computing workloadsWhether you’re into coding, systems, or scientific computing, this is your chance to explore the power behind supercomputers—on a scale you can hold in your hands!Class is limited to 20 students so first come first serve.Dates: January 13, 14, and 15, 2026 1PM-4PMFor more information, please send email to mullenj@mit.eduSign-up form: https://bit.ly/mini-supercomputer-2026

IAP 2026 provides members of the MIT community (students, faculty, staff, and alumni) with a unique opportunity to participate in a wide variety of activities, including this lecture series on climate change produced by MIT’s Center for Sustainability Science and Strategy (CS3). Please join CS3 during IAP 2026 to learn more about the science of climate change and policies aimed at stabilizing the global climate.

On Wednesday nights you are invited to come to The Table for peaceful Christian worship in the Chapel at 5:15 pm and dinner in the Main Dining Room of W11 at around 6:30 pm.We worship with beautiful songs, open conversation about the Scriptures, prayers and a simple sharing of communion around the altar. Then we enjoy dinner together and good company together.
