A new understanding of the physics of conductive materials has been uncovered by scientists observing the unusual movement of electrons in graphene.
Prof Sir Andre Geim delivered the 2011 Cockcroft Rutherford Lecture entitled 'A Random Walk to Graphene'.
In the lecture, which was designed to appeal to scientists and non-scientists alike, Andre talked about his ground-breaking and ultimately Nobel Prize - winning discovery, which was realised using sticky tape and pencil lead.
With his engaging style and sense of humour, Andre shared his passion for his work, the impact of this great find and possible future applications of the world's thinnest material.
