Congratulations, John!

In 1962, in the old Cavendish Lab in Cambridge, UK, Brian Josephson discovered the Josephson effect and was honored by the 1973 Nobel Prize in Physics, shared with Ivar Giaever of GE Global Research (and a 3rd person, Leo Esaki). John Clarke, who went to Cambridge after Josephson, picked up the discovery and greatly advanced the effect's scientific understanding and applications. One of which was,  so it happened, to the detection of magnetic field signals in NMR in the early 2000's. That's when I learned, as his PhD student, the prominent medical imaging modality of MRI. Last week, John was announced to be one of the three physicists to share the 2025 Physics Nobel Prize, and to anyone who knows him, this is a proper, well-made decision. Not only for his scholarly achievements, but for the humble, curious, and example-setting leadership that he has displayed as a teacher, researcher, and a true academic.
