In my teens Carl Segan left an indelible impression. It's ironic this narrative rings strongly today. Carl Edward Sagan (November 9, 1934 - December 20, 1996) was an American astronomer. He tried to make science popular. He thought about what life from other planets would be like. He said that people should look for life on other planets (SETI). He is world famous for his popular science books and the television series Cosmos, which he co-wrote and presented. He said people should use the scientific method.
