Thomas Jefferson, September 6, 1789

"You never change things by fighting the existing reality. To change something, build a new model that makes the existing model obsolete."

Buckminster Fuller, philosopher, futurist and global thinker (1895 - 1983)

"If there are to be problems, may they come during my life-time so that I can resolve them and give my children the chance of a good life."
