There are 1 billion nanometers (nm) in one meter. A meter is approximately 3 feet.
The original transistor built by Bell Labs in 1947 could be held in your hand, while hundreds of Intel’s new 45nm transistor can fit on the surface of a single red blood cell.
If a house shrunk at the same pace transistors have, you would not be able to see a house without a microscope. To see the 45nm transistor, you need a very advanced microscope.
The price of a transistor in one of Intel’s forthcoming next-generation processors -- codenamed Penryn -- will be about 1 millionth the average price of a transistor in 1968. If car prices had fallen at the same rate, a new car today would cost about 1 cent.
