Joule

The Joule (J) is the SI unit of energy. One Joule is the energy expended when a force of one newton is applied over a displacement of one meter in the direction of the force. The use of the joule is probably limited in Radiation Protection but is used in the definition of Absorbed Dose and the Electron volt.

This revolution, the information revolution, is a revolution of free energy as well, but another kind: free intellectual energy.
