Sagan discusses the search for a quantitative means of measuring intelligence. He argues that the brain to body mass ratio is an extremely good correlative indicator for intelligence, with humans having the highest ratio and dolphins the second highest,[1] though he views the trend as breaking down at smaller scales, with some small animals (ants in particular) placing disproportionately high on the list. Other topics mentioned include the evolution of the brain (with emphasis on the function of the neocortex in humans), the evolutionary purpose of sleep and dreams, demonstration of sign language abilities by chimps and the purpose of mankind's innate fears and myths. The title "The Dragons of Eden" is borrowed from the notion that man's early struggle for survival in the face of predators, and in particular a fear of reptiles, may have led to cultural beliefs and myths about dragons. The Dragons of Eden won a Pulitzer Prize.[2] In 2002, John Skoyles and Dorion Sagan published a follow-up entitled Up from Dragons.[3] SummaryThe book is an expansion of the Jacob Bronowski Memorial Lecture in Natural Philosophy which Sagan gave at the University of Toronto. In the introduction Sagan presents his thesis – that "the mind ... [is] a consequence of its anatomy and physiology and nothing more" – in reference to the works of Charles Darwin and Alfred Russel Wallace.[citation needed] In chapter 2, Sagan briefly summarizes the entire evolution of species starting from the Big Bang to the beginning of the human civilization with the help of a "Cosmic Calendar", an analogy where one year in the calendar corresponds to the time since the Big Bang. Sagan used the same analogy in the more-widely known television series Cosmos. It is disconcerting to find that in such a cosmic year the Earth does not condense out of interstellar matter until early September, dinosaurs emerge on Christmas Eve; flowers arise on December 28; and men and women originate at 10:30 P.M. on New Year's Eve. All of recorded history occupies the last 10 seconds of December 31; and the time from the waning of the Middle Ages to the present occupies little more than one second. CONTACTContact is a 1985 hard science fiction novel by American scientist Carl Sagan. It deals with the theme of contact between humanity and a more technologically advanced, extraterrestrial life form. It ranked No. 7 on the 1985 U.S. bestseller list. The only full work of fiction published by Sagan, the novel originated as a screenplay by Sagan and Ann Druyan (whom he later married) in 1979; when development of the film stalled, Sagan decided to convert the stalled film into a novel. The film concept was subsequently revived and eventually released in 1997 as the film Contact starring Jodie Foster. PlotThe MessageAs a child, Eleanor "Ellie" Arroway displays a strong aptitude for science and mathematics. Dissatisfied with a school lesson, she goes to the library to convince herself that pi is transcendental. In sixth grade, her father Theodore ("Ted") dies. John Staughton, her new stepfather, does not show as much support for her interests. Ellie refuses to accept him as a family member and believes her mother only remarried out of weakness. After graduating from Harvard University, Ellie receives a doctorate from Caltech supervised by David Drumlin, a well-known radio astronomer. She becomes the director of "Project Argus", a radio telescope array in New Mexico dedicated to the search for extraterrestrial intelligence (SETI). This puts her at odds with most of the scientific community, including Drumlin, who tries to have the funding to SETI cut off. The project eventually discovers a signal containing a series of prime numbers coming from the Vega system, 26 light years away.[a][b] Further analysis reveals information in the polarization modulation of the signal: a retransmission of Adolf Hitler's opening speech at the 1936 Summer Olympics in Berlin, the first television signal powerful enough to escape Earth's ionosphere.[1] The President of the United States meets with Ellie to discuss the implications of the first confirmed communication from extraterrestrial beings. Ellie begins a relationship with Presidential Science Advisor Ken der Heer. With the help of her Soviet colleague Vaygay Lunacharsky, Ellie manages to set up redundant monitoring of the signal so that a telescope remains pointed at Vega at all times. A third message is discovered describing plans for an advanced machine. With no way of decoding the 30,000 pages, SETI scientists surmise that there must be a primer that they have missed. The MachineAt the President's insistence, Ellie agrees to meet with two religious leaders, Billy Jo Rankin and Palmer Joss. A lifelong religious skeptic, Ellie tries to convince Joss of her faith in science by standing near a heavy Foucault pendulum and trusting that its amplitude will not increase. Although dismissing Rankin's outbursts, Ellie is intrigued by Joss' worldview. Shortly after, Ellie travels to Paris to discuss the Machine with a newly formed consortium. The participants agree that the Machine is a dodecahedron-shaped vehicle with five seats. At the conference, Ellie meets Devi Sukhavati, a doctor who left India to marry the man she loved, only to lose him to illness a year later. The final piece of the message is discovered when S. R. Hadden, a billionaire in high-tech industries with an obsessive interest in the concept of immortality, suggests that Ellie check for phase modulation. This reveals the primer, thus allowing construction of the Machine to begin. The American and Soviet governments enter a race to construct identical copies of the Machine. As errors in the Soviet project are discovered, the American Machine becomes the only option. Ellie applies to be one of the five passengers, but her spot is given to David Drumlin instead. Despite heavy security, a group of extremists manages to get a bomb into one of the fabrication plants in Wyoming. During a test of the machine, the bomb explodes, killing Drumlin and postponing completion of the Machine indefinitely. Ellie's family also suffers when her mother has a stroke, causing paralysis. John Staughton accuses Ellie of ignoring her own mother for years. Ellie learns that S. R. Hadden has taken up residence aboard a private space station. While on board, he reveals that his company has been covertly building a third copy of the Machine in Hokkaido, Japan. The activation date is set for December 31, 1999, and Ellie, Vaygay and Devi are given three of the seats. The other two are given to Abonnema Eda, a Nigerian physicist credited with discovering the theory of everything, and Xi Qiaomu, a Chinese archaeologist and expert on the Qin dynasty. While in Japan, Ellie receives a medallion from Joss, which she carries aboard the Machine as it is activated. The GalaxyOnce activated, the dodecahedron transports the group through various wormholes to a station near the center of the Milky Way. The station contains a surreal Earth-like beach where the five are split up. Ellie meets an extraterrestrial in a form indistinguishable from Ted Arroway, who explains his people's reasons for making contact, and tells her of their ongoing project to alter the properties of the universe by accumulating enough mass in Cygnus A to counter the effects of entropy. The wormhole system (spanning many galaxies) was built by unknown precursors, and he hints at the discovery of artificial messages encoded within transcendental numbers like π. Ellie is reunited with the other four travellers, who have also met simulations of their loved ones. She captures video evidence of the encounter before the dodecahedron takes them back to Earth. Upon returning, the passengers discover that what seemed like more than a day took no time at all from Earth's perspective. All of their video footage and photos have been erased, presumably by magnetic fields in the wormholes. After seeing that Hadden is apparently dead and the transmission has somehow been stopped without a 26-year delay, government officials accuse the travellers of an international conspiracy. They blackmail Ellie and her fellow travellers into silence until more evidence can be found. Palmer Joss becomes one of the few people willing to believe her story, which she can only justify on faith. Hadden is revealed by the novel to have faked his death, instead launching himself out of the solar system on a single-man-mission with the use of advanced cryogenics, though this information is not revealed to any characters. Acting on the suggestion of "Ted", Ellie works on a program to compute the digits of π to heretofore-unprecedented lengths. Ellie's mother dies before this project delivers its first result. A final letter from her informs Ellie that John Staughton, not Ted Arroway, is Ellie's biological father. When Ellie looks at what the computer has found, she sees a circle rasterized from 0s and 1s that appear after 1020 places in the base 11 representation of π. This provides evidence of her journey and suggests intelligence is behind the universe itself.
