Hour Two: Tiny Circuits
/ Tim Berners-Lee
Three little letters -- w-w-w -- have come to change how we communicate,
get our information, and do our shopping. In this hour of Science
Friday, Ira talks to the inventor of the World Wide Web, Tim Berners-Lee,
about the history and future of the web -- including web standards,
the exchange of data in the Semantic Web, and the tools and technologies
responsible for web communication.
Plus, we'll find out about a means of computation based on the movement
of molecules. Through a painstaking process of lining up carbon monoxide
molecules on a copper surface, IBM scientists have managed to build
circuits capable of basic computer operations when one molecule is
knocked into others, setting off a domino-like effect. Though impractical,
the technique is said to point in new directions for ultra-small computing.
