The law that the number of tranistors on a circuit board will increase exponetially every 18 months (double).
This has held true since the 50’s and is expected to continue until at least 2015, however with all things exponential it will only have a certain shelf life.
Why?
Well once we get so small that transistors are running the size of an atom, where do we go from there?
Perhaps those answers will be discovered once the Large Hadron Collider starts churning out results.
