Andrei Geim and Konstantin Novoselov won the nobel prize for their researches on graphene. Graphene is a new material that derives from Graphite (the inside of pencils) and it turns out to be the best heat conductor available and to be able to conduct electricity as fast as copper. Its uses are almost infinte and they predict that it might take the place of silicon for faster computers in the future.\nHaving to deal with scarcity people find clever ways to go about with what is available to them, and often by inventing new things, in this case *Graphene*, we can make better use of resources and avoid wastes of other, less efficent, materials.
