Born in New York in November 9, 1934.
Studied at the University of Chicago, where he received a Ph.D. in astrophysics.
Married to Ann Druyan.
Widely recognized for his scientific works, will probably be most remembered by his efforts to increase scientific literacy.
"Most organisms on Earth depend on their genetic information, which is 'prewired' into their nervous systems, to a much greater extent than they do on their extragenetic information, which is acquired during their lifetimes. For human beings, and indeed for all mammals, it is the other way around. While our behavior is still significantly controlled by our genetic inheritance, we have, trough our brains, a much richer opportunity to blaze new behavioral and cultural pathways on short time scales. We have made a kind of bargain with nature: our children will be difficult to rise, but their capacity for new learning will greatly enhance the capacity for survival of the human species. In addition, human beings have, in the most recent few tenths of a percent of our existence, invented not only extragenetic but also extrasomatic knowledge; information stored outside our bodies, of which writing is the most notable example."
(From "The Dragons of Eden")
"There is no guarantee that the universe will conform to our predispositions. But I do not see how we can deal with the universe - both the outside and the inside universe - without studying it. The best way to avoid abuses is for the populace in general to be scientifically literate, to understand the implications of such investigations. In exchange for freedom of inquiry, scientists are obliged to explain their work. If science is considered a closed priesthood, too difficult and arcane for the average person to understand, the dangers of abuse are greater. But if science is a topic of general interest and concern - if both its delights and its social consequences are discussed regularly and competently in the schools, the press, and at the dinner table - we have greatly improved our prospects for learning how the world really is and for improving both it and us."
(From "Broca's Brain")
