Metcalfe's Law
Metcalfe's law states that the value of a network equals approximately the square of the number of users of the system (n2). Since a user cannot connect to itself, the actual calculation is the number of diagonals and sides in an n-gon:


 * $$\frac{n(n-1)}{2}.$$

First formulated by Robert Metcalfe in regard to Ethernet, Metcalfe's law explains many of the network effects of communication technologies and networks such as the Internet and World Wide Web.
