Melvyn Bragg and his guests discuss the history of crystallography, the study of crystals and their structure. The discovery in the early 20th century that X-rays could be diffracted by a crystal revolutionised our knowledge of materials. This crystal technology has touched most people's lives, thanks to the vital role it plays in diverse scientific disciplines - from physics and chemistry, to molecular biology and mineralogy. To date, 28 Nobel Prizes have been awarded to scientists working with X-ray crystallography, an indication of its crucial importance. Melvyn Bragg is joined by Judith Howard, Professor of Chemistry at the University of Durham; Chris Hammond, Life Fellow in Material Science at the University of Leeds; and Mike Glazer, Emeritus Professor of Physics at the University of Oxford and Visiting Professor of Physics at the University of Warwick.
