How Big is a Nanometer?
•10-9 meters see http://www.wordwizz.com/10exp-9.htm
•The distance your fingernails grow in one second
•One hundred million times smaller than a large potato
•If you stretched a rubber band appr. one yard in length from Los Angeles to New York, then one nanometer would have been stretched to 0.16 inches.

Moore’s Law is not a law of physics—it’s a prediction. Will eventually hit barrier—feature size too small—quantum effects.
Optimists—another 10 years,
pessimists –5 years.
Quantum computer, biological, organic computers, more parallelism in short term.
15 years ago people thought today’s chips would not be possible. Now talking about just a few atoms making the various regions---used to be thousands. Part of nano revolution as well.
avd: have just bought a “nanomanipulator” for Brown – let’s you move atoms around!
