The Isaac Newton Medal and Lecture, awarded annually, is the most prestigious honour bestowed by the Institute of Physics (IOP), one of the largest scientific societies in the world.
Sir Michael’s ideas and theories have overarching implications in many areas of physics including quantum and he will be a speaker at the IOP’s International Year of Quantum celebrations next month [4 November].
In a career spanning more than 60 years, Professor Berry’s breakthroughs have had applications in areas such as condensed matter, quantum information and high-energy physics, as well as optics, nonlinear dynamics, and atomic and molecular physics.
He is renowned for his work on geometric phases, now known as the Berry Phase. His 1984 paper, ‘Quantal phase factors accompanying adiabatic changes’ has more than 12,000 citations and remains influential today.
Professor Berry’s citation for the Isaac Newton Medal and Lecture 2025 reads: “In mathematics, his work is the basis for research in analysis, geometry and number theory. Professor Berry has been an exemplar of the power of curiosity-driven research, whose contributions can truly be seen as standing in the tradition of Isaac Newton.”
On receiving the award, Professor Berry said: “This is unexpected recognition for six decades of obsessive scribbling. My work has been applied to a diverse range of topics, connecting quantum geometry to car parking in tight spaces, to gaining insights into the physics of nature such as tidal bores, tsunamis, rainbows, and polarised light in the blue sky.”
Professor Jennifer McManus, Head of the School of Physics at the University of Bristol, added: “This is a very well-deserved award to Michael who has made many fundamental, important contributions to physics. He is an enthusiastic member of the Bristol physics community, where his insights and contributions are highly valued here and around the world. His curiosity about the world and his unique ability to seek understanding through physics has provided insights into diverse topics from quantum mechanics to levitating frogs. Many congratulations on this award.”
Many other physicists have also been honoured today with IOP Awards including teachers, businesses, apprentices, researchers and science communicators. The details of winners can be found here: 2025 IOP Award winners | Institute of Physics.
