In their first lecture, John Meurig Thomas and David Phillips examine the symmetry and other striking physical characteristics of minerals and gemstones.
Lasers are not just for pointing at the board. David Phillips shows us the different applications of laser from their use in research to detecting pollutants in the atmosphere
Levitating with superconductors, charging with semiconductors and combusting with catalysts. John Meurig Thomas demonstrates the use of these materials in our everyday life
Laser technology is being used in medicine to investigate, diagnose and cure. David Phillips shows us the different uses of lasers on the human body
Some atoms are radioactive, waiting to explode and hurl out a small 'chip' thus becoming quite a different atom — an atom of a different chemical element.
Ions are atoms or molecules that have gained an electric charge — by gaining or losing a spare negative electron.
