One of them was a project which was very very important to him and was an accident. Doug talked to air force research manager about components getting smaller. Transistors etc. So Doug suggested that he carry out a study to see what would happen if you make the components smaller - knowing that there would be more demand for computer power and the only practical ways to get faster and more powerful computers is to make the components smaller.

So how could you make them smaller? Would there be any problems? What happens?

Lets just consider the scaling issue for a while.
