  • Mark Miodownik describes the advantages that metal has over earlier substances used by man (rock and bone); it can be sharpened and straightened. He then describes the structure of metals as crystalline, but unlike quartz. A computer animation is used. He ends by describing how 'working' a metal makes it stronger, by making 'blockages' in the structure.
