I spent most of Saturday travelling between the UK and Anaheim in Southern California, so I was up very early on Sunday with jetlag. So just as the sun was rising over the Santa Ana Mountains on a crisp morning, I went for a run in the suburban neighbourhood just south of the Anaheim Convention Center. As I made my way back to my hotel, the sidewalks were already thronging with physicists on their way to register for the Global Physics Summit (GPS) – which is being held in Anaheim by the American Physical Society (APS). The GPS combines the APS’s traditional March and April meetings, which focus on condensed-matter and particle and nuclear physics, respectively. This year, about 14,000 physicists are expected to attend.
I popped out at lunchtime and spotted a “physics family” walking along Harbor Boulevard, with parents and kids all wearing vintage APS T-shirts with clever slogans. They certainly stood out from most families, many of which were wearing Mickey Mouse ears (Disneyland is just across the road from the convention centre).
Uniting physicists The GPS starts in earnest bright and early Monday morning, and I am looking forward to spending a week surrounded by thousands of fellow physicists. While many physicists in the US are facing some pretty dire political and funding issues, I am hoping that the global community can unite in the face of the anti-science forces that have emerged in some countries. This year is the International Year of Quantum Science and Technology, so it’s not surprising that quantum mechanics will be front and centre here in Anaheim. I am looking forward to the “Quantum Playground”, which will be on much of this week. It promises, “themed areas; hands-on interactive experiences; demonstrations and games; art and science installations; mini-performances; and ask the experts”. I’ll report back once I have paid a visit.

New for 2025, the American Physical Society (APS) is combining its March Meeting and April Meeting into a joint event known as the APS Global Physics Summit. The largest physics research conference in the world, the Global Physics Summit brings together 14,000 attendees across all disciplines of physics. The meeting takes place in Anaheim, California (as well as virtually) from 16 to 21 March.
Uniting all disciplines of physics in one joint event reflects the increasingly interdisciplinary nature of scientific research and enables everybody to participate in any session. The meeting includes cross-disciplinary sessions and collaborative events, where attendees can meet to connect with others, discuss new ideas and discover groundbreaking physics research.
The meeting will take place in three adjacent venues. The Anaheim Convention Center will host March Meeting sessions, while the April Meeting sessions will be held at the Anaheim Marriott. The Hilton Anaheim will host SPLASHY (soft, polymeric, living, active, statistical, heterogenous and yielding) matter and medical physics sessions. Cross-disciplinary sessions and networking events will take place at all sites and in the connecting outdoor plaza.
With programming aligned with the 2025 International Year of Quantum Science and Technology, the meeting also celebrates all things quantum with a dedicated Quantum Festival. Designed to “inspire and educate”, the festival incorporates events at the intersection of art, science and fun – with multimedia performances, science demonstrations, circus performers, and talks by Nobel laureates and a NASA astronaut.
Finally, there’s the exhibit hall, where more than 200 exhibitors will showcase products and services for the physics community. Here, delegates can also attend poster sessions, a career fair and a graduate school fair.
Precision motion drives innovative instruments for physics applications

For over 25 years Mad City Labs has provided precision instrumentation for research and industry, including nanopositioning systems, micropositioners, microscope stages and platforms, single-molecule microscopes and atomic force microscopes (AFMs). This product portfolio, coupled with the company’s expertise in custom design and manufacturing, enables Mad City Labs to provide solutions for nanoscale motion for diverse applications such as astronomy, biophysics, materials science, photonics and quantum sensing.
Mad City Labs’ piezo nanopositioners feature the company’s proprietary PicoQ sensors, which provide ultralow noise and excellent stability to yield sub-nanometre resolution and motion control down to the single picometre level. The performance of the nanopositioners is central to the company’s instrumentation solutions, as well as the diverse applications that it can serve.
Within the scanning probe microscopy solutions, the nanopositioning systems provide true decoupled motion with virtually undetectable out-of-plane movement, while their precision and stability yields high positioning performance and control. Uniquely, Mad City Labs offers both optical deflection AFMs and resonant probe AFM models.
