Carl Edward Sagan (/ˈseɪɡən/; November 9, 1934 -- December 20, 1996) was an American astronomer, astrophysicist, cosmologist, author, science popularizer and science communicator in astronomy and natural sciences. His books: https://www.amazon.com/gp/search?ie=UTF8&tag=tra0c7-20&linkCode=ur2&linkId=2944ce7277c6bf85fa527a369052fa7f&camp=1789&creative=9325&index=books&keywords=carl%20sagan He spent most of his career as a professor of astronomy at Cornell University where he directed the Laboratory for Planetary Studies. He published more than 600 scientific papers and articles and was author, co-author or editor of more than 20 books. He advocated scientific skeptical inquiry and the scientific method, pioneered exobiology and promoted the Search for Extra-Terrestrial Intelligence (SETI). Sagan is known for his popular science books and for the award-winning 1980 television series Cosmos: A Personal Voyage, which he narrated and co-wrote. The book Cosmos was published to accompany the series. Sagan wrote the novel Contact, the basis for a 1997 film of the same name. He attended the University of Chicago, where he participated in the Ryerson Astronomical Society,[10] received a bachelor of arts in self-proclaimed "nothing" with general and special honors in 1954, a bachelor of science in physics in 1955, and a master of science in physics in 1956 before earning a PhD in astronomy and astrophysics in 1960.[11][12][13] During his time as an honors program undergraduate, Sagan worked in the laboratory of the geneticist H. J. Muller and wrote a thesis on the origins of life with physical chemist H. C. Urey. He used the summer months of his graduate studies to work with planetary scientist Gerard Kuiper (thesis advisor), physicist George Gamow, and chemist Melvin Calvin. From 1960 to 1962 Sagan was a Miller Fellow at the University of California, Berkeley.[14] From 1962 to 1968, he worked at the Smithsonian Astrophysical Observatory in Cambridge, Massachusetts. At the same time, he worked with geneticist Joshua Lederberg. Sagan lectured and did research at Harvard University until 1968, when he moved to Cornell University in Ithaca, New York, after being denied tenure at Harvard. He became a full professor at Cornell in 1971, and he directed the Laboratory for Planetary Studies there. From 1972 to 1981, Sagan was the Associate Director of the Center for Radiophysics and Space Research (CRSR) at Cornell. Sagan was associated with the U.S. space program from its inception. From the 1950s onward, he worked as an advisor to NASA, where one of his duties included briefing the Apollo astronauts before their flights to the Moon. Sagan contributed to many of the robotic spacecraft missions that explored the Solar System, arranging experiments on many of the expeditions. He conceived the idea of adding an unalterable and universal message on spacecraft destined to leave the Solar System that could potentially be understood by any extraterrestrial intelligence that might find it. Sagan assembled the first physical message that was sent into space: a gold-anodized plaque, attached to the space probe Pioneer 10, launched in 1972. Pioneer 11, also carrying another copy of the plaque, was launched the following year. He continued to refine his designs; the most elaborate message he helped to develop and assemble was the Voyager Golden Record that was sent out with the Voyager space probes in 1977. Sagan often challenged the decisions to fund the Space Shuttle and the International Space Station at the expense of further robotic missions.[15] Sagan taught a course on critical thinking at Cornell University until he died in 1996 from pneumonia, a few months after finding that he was in remission of myelodysplastic syndrome. Former student David Morrison describes Sagan as "an 'idea person' and a master of intuitive physical arguments and back-of-the-envelope calculations."[16] Sagan's contributions were central to the discovery of the high surface temperatures of the planet Venus. In the early 1960s no one knew for certain the basic conditions of that planet's surface, and Sagan listed the possibilities in a report later depicted for popularization in a Time--Life book, Planets. His own view was that Venus was dry and very hot as opposed to the balmy paradise others had imagined. He had investigated radio emissions from Venus and concluded that there was a surface temperature of 500 °C (900 °F). As a visiting scientist to NASA's Jet Propulsion Laboratory, he contributed to the first Mariner missions to Venus, working on the design and management of the project. Mariner 2 confirmed his conclusions on the surface conditions of Venus in 1962. http://en.wikipedia.org/wiki/Carl_sagan

"coal and oil must cease to be important factors in the sustenance of human life on this planet... Whatever our resources of primary energy may be in the future, we must, to be rational, obtain it without consumption of any material.”
" It is our duty to coming generations to leave this store of energy intact for them, or at least not to touch it until we shall have perfected processes for burning coal more efficiently. Those who are coming after us will need fuel more than we do. We should be able to manufacture the iron we require by using the sun's energy, without wasting any coal at all."

Wow this was only 26 years ago and he said "our numbers have reached 5.3 billion." We are at like 7.1 billion now. Damn.
-
the theologist in the end sound the most complicated, whilst carl zoogan sounds like he's deluding itself. btw retarded audience X-D
-
55:40 - Carl SASSgan! :D

Crude OIl ends in 2052 according to worldometer. Long Live the Green Hemp Peace.

OMG, wtf is wrong with that announcer? Seriously, clear your throat, remember what you want to say and just say it.. had to skip ahead, so annoying >:o
-
Back in 1990 humans were "only" 5.3billions and now, 26 years later only, we have incresed the population in 35%
We must stop! Holy shit! -
Carl just sounds like a person who has no profit expectations and who has a brain, impossible not to agree with a logical man :) 26 years has passed, they have continued until finishing the oil. When they finish the oil, they will say oh look now sun energy is more economical. There is a reason why people like Carl Sagan cannot be accepted as a leader, the only reason is those greedy capitalist bastards and ignorant humans.

"but which is more prudent, which is wiser? to do nothing and hope that the mistake has been made or to take these predictions seriously even if is a chance you will the precautions you will take will be unnecessary"

Dear The Film Archives, I would like to say, thank you, to you, for taking the time, energy and effort to both upload and share this video with the youtube family. THank you!

Sagan inspired me to drive a used Prius as a 28 year old "hip / cool" guy who could afford a BMW

Why was the Q&A section cut off?

LANGDON GILKEY IS AN ASSHOLE!!!!

He sounds like Bernie Sanders does today, such a shame that Carl went unheard for so long, and only just now in 2015 are people finally starting to open their eyes to the harm we've been causing the planet.
We miss you Carl Sagan, the world needs more men like you! -
Economic interests align with ecological health when we charge substantial fees to industries that put pollution, deplete resources or disturb wildlife habitat.
Sharing fee proceeds among all the world's people would mean an end to poverty throughout the world. We could have a sustainable and more just civilization.

Probably thee greatest communicator of Wisdom of all time!
Neil deGrasse Tyson, Richard Feynman and the four horsemen, in that order. -
Stop this idiotic debate between science and religion we have more important issues. Sagan is a very moral man I admire him greatly he was like Noan Chomsky in that he cared more about what people do and less about what they believed when our species is threaated accross the board. I love his speech here!!

My view is that Dr. Sagan was one of the greatest people of our time. He was brilliant, ethical, a great communicator, and he spoke the truth because he cared.
