Intelligent Life in the Universe – Usado

A provocative and entertaining look at a topic of evergrowing interest.

In 1963, a unique collaboration began between world-famos Russian astronomer I. S. Shklovskii and leading American space scientist, author and lecturer Carl Sagan. Though the two have never personally met, they co-wrote the first popular and accurate modern discussion of the entire panorama of natural evolution -including the origins of the universe, the evolution of stars and planets, the beginnings of life on earth and the development of intelligence and technical civilizations among galactic communities. While Shklovskii wrote the basic text, Sagan heavily annotated and supplemented the material, clarifying concepts of the scientific layman and adding his own insightful. comments.
