An interesting article about the discovery of a new type of electrical device. Based on the equations relating charge and magnetism, Leon Chua deduced that the mathematics of electric circuits was missing an element (one that directly relates charge to magnetic flux) - he dubbed the missing element a memristor.

Now scientists believe they have found a physical device that has this effect ... at nanoscales. The device could have some amazing applications for computation.
