Architectural Applications of Complex Adaptive Systems
This paper presents methods and case studies of approaching architectural design and fabrication utilizing Complex Adaptive Systems (CASs). The case studies and observations described here are findings from a continuing body of research investigating applications of computational systems to architectural practice. CASs are computational mechanisms from the computer science field of Artificial Life that provide frameworks for managing large numbers of elements and their inter-relationships. The a

Lugosi teaches math - convergence of series 2
In part 2 of Béla Lugosi's lecture on convergence of series, he continues to discuss integration of the limit function in these series or sequences. He then goes further into applying these into power series. This is a video for advanced math students who are well into Calculus and Calculus II.
Lugosi teaches math - convergence of series 3
Béla Lugosi teaches advanced mathematical concepts in this video. How one uses power series to solve varying kinds of problems is discussed, and Lugosi explains how this one application shows the power of power series. It also show that power series have a very important and powerful and analytical technique. A great series for any advanced mathematics student who is working in Calculus and Calculus II.
This video is accompanied by text. "In his 1794 book The Age of Reason, Thomas Paine advanced a religious philosophy called Deism that struck at the tenets of organized religions, particularly Calvinism as it was practiced by the Puritans. Paine claimed that churches were “set up to terrify and enslave mankind, and monopolize power and profit.” These thoughts were shocking to Americans who were imbued with a strong religious tradition. At the same time, Paine’s ideas appealed to many Ameri

The first Americans came from Asia, beginning as early as thirty thousand years ago, over a land bridge that formed at the Bering Strait during the Ice Age. The new immigrants were hunters and gatherers, and over a period of fifteen thousand years various groups spread over the American continents. By the time of the European “discovery” of the New World, there were perhaps as many as 100 million native Americans, the vast majority living in Central and South America.
