InsulincrystalsThat scientific principle of diffraction of X-rays by crytals, discovered in 1913, by father and son William and Lawrence Bragg has made possible much of the materials research that today takes place at Diamond Light Source. To mark the occasion, Dr John Jenkin, the biographer of the British scientific duo, gave a lecture, while Professor Thomas Sorensen, principal beamline scientist at the science facility, spoke about the importance of X-ray crystallography to modern-day scientists.
