President Clinton, 2000 The National Nanotechnology Initiative
“Imagine the possibilities: materials with ten times the strength of steel and only a small fraction of the weight -- shrinking all the information housed at the Library of Congress into a device the size of a sugar cube -- detecting cancerous tumors when they are only a few cells in size.”

Impact Powerful Computers
We’ll have more computing power in the volume of a sugar cube than the sum total of all the computer power that exists in the world today More than 1021 bits in the same volume Almost a billion Pentiums in parallel
20
Impact Nanomedicine Disease and ill health are caused largely by damage at the molecular and cellular level Today’s surgical tools are huge and imprecise in comparison
21
Impact Nanomedicine In the future, we will have fleets of surgical tools that are molecular both in size and precision. We will also have computers much smaller than a single cell to guide those tools.
