Moore’s Law wikipedia
Moore's Law “Integrated circuits will lead to such wonders as home computers— or at least terminals connected to a central computer —automatic controls for automobiles, and personal portable communications equipment.” Gordon E. Moore, Electronics, 38, 8, 1965
Investing Nanotechnology • The Federal funding for nanotechnology has increased from approximately $464 million in 2001 to nearly $1.5 billion for the 2009 fiscal year. • Estimated from 2005: European Union (EU) and Japan invested approximately $1.05 billion and $950 million respectively in nanotechnology. Behind them were Korea, China and Taiwan with $300 million, $250 million and $110 million respectively invested in nanotechnology research and development. http://www.nano.gov/
