John C. H. Spence FRS is Snell Professor of Physics at Arizona State University, where he teaches condensed matter physics with research in biophysics. He is currently Director of Science for the National Science Foundation's eight-campus BioXFEL consortium. This is devoted to applications of the recently invented hard x-ray free-electron laser to structural biology, providing movies of molecular machines at work with femtosecond time resolution. John is the author of texts on electron microscopy, and a keen musician, pilot and sailor.
From Faraday and Maxwell describing how light propagates to Einstein showing the constancy of the speed of light and all else entailed in his theories of special and general relativity, John Spence recounts this history with a focus on the key personalities that helped it move forward, the science they did and the legacy they left behind. * Marios Karouzos, Nature Astronomy *
