About this event
Modern computing is running into hard physical limits: chips use too much power, generate too much heat, and struggle to keep getting faster in the ways we have come to expect. Ultrafast magnetism sits at the center of a promising alternative, exploring how magnetic states can be manipulated on extremely short timescales to enable memory and logic that are both faster and far more energy-efficient. This meetup is for people who want to understand that shift in clear, grounded terms. Whether you come from physics, engineering, research, startups, or simple curiosity about where computing goes next, you will leave with a sharper view of why ultrafast magnetic phenomena matter and how they connect to greener hardware. About the Event This is an in-person evening gathering in San Francisco focused on the science and real-world relevance of ultrafast magnetism. The event is designed to be approachable without flattening the subject: serious enough for technically engaged attendees, but framed in a way that also welcomes people who are adjacent to the field and want a meaningful introduction. At its core, the event is about a big question: how do we compute more efficiently when conventional scaling starts to fail? Ultrafast magnetism offers one path forward by examining how magnetic materials respond to light, electric currents, and other stimuli on ultrashort timescales, opening new possibilities for switching, storage, and information processing. Expect a meetup format that blends ideas and people. This is not just a one-way lecture for passive listeners. It is also a place to talk with others who care about frontier physics, advanced hardware, and the environmental cost of computation. What to Expect You can expect an evening structured around both learning and conversation. The central theme is the physics behind ultrafast magnetic effects and why those effects could matter for future generations of computing hardware. Likely points of discussion include: What ultrafast magnetism actually means in physical terms Why magnetic switching speed matters for memory and computation How energy use and heat dissipation shape the future of chip design Where greener computing needs new materials and new device concepts How basic research connects to practical hardware ambitions Because this is a meetup setting, there is also room for informal exchange. You should expect opportunities to ask questions, compare perspectives, and meet others thinking about related topics across science, technology, and innovation. The event tags point to a broader social and community dimension as well. That means the experience is not only about absorbing information; it is also about finding your people, testing ideas in conversation, and building local connections around a specialized but increasingly important topic. Why Attend If you care about the future of computing, this topic matters for reasons that go well beyond academic interest. Faster systems are no longer enough on their own; energy efficiency is becoming a first-order design constraint. Understanding the physics that could unlock lower-power information technologies gives you a better framework for evaluating where research, investment, and product development may head next. This event can help you connect the dots between disciplines that are often discussed separately. Physics explains the underlying mechanisms, materials science shapes what is possible, and computing provides the application pressure. Seeing those layers together makes it easier to understand both the promise and the difficulty of building truly better hardware. You may come away with: A clearer mental model of how ultrafast magnetic processes differ from conventional electronic approaches Better language for discussing speed, switching, and energy efficiency in emerging hardware A stronger sense of which problems are fundamental physics challenges versus engineering challenges Useful conversations with others interested in advanced computing, climate-conscious technology, and deep tech research Just as important, attending in person gives you context that is hard to get from papers, headlines, or online clips alone. You get to hear how people frame the field, what questions keep coming up, and where curiosity or skepticism is strongest. Practical Details Location: In person in San Francisco, USA. This is a face-to-face event, so plan for a more engaged, conversational atmosphere than a webinar or livestream. Date and time: Wednesday, February 18 at 7:00 PM PST. As an evening event, it is well suited to people coming after work, classes, or lab time. A few practical reasons the format matters: You will have a better chance to network with other attendees interested in physics and future computing It is easier to ask nuanced questions in person, especially on technical topics Informal discussion before or after the core program can be as valuable as the main session itself If this topic sits anywhere near your interests, come ready to listen closely, ask smart questions, and meet people who are also thinking seriously about what comes after conventional computing architectures. This event is a strong fit for anyone who wants to understand not just that greener computing is needed, but which physical ideas might actually help make it possible.
Who should attend
