Billions and Billions How Carl Sagan Discovered The Secrets Of The Universe 14 Billion Yea

Graphic/ButterMochi Journal

                     t was the 1939 World’s Fair, the grandest of celebrations regarding recent technological innovation that                            would pave cobblestone streets into interstate highways. Even the most jaded of cynics couldn’t resist the                   temptation to marvel and mutter, “Well, that’s something, isn’t it?” Jaws dropped at the sight of the first colored photographs, retro-style robots, and machines that moved pictures and sounds that scientists had labeled “the television.” Among these dropped jaws was 5-year-old Carl Sagan, though his thoughts scattered as he began wondering how further extraterrestrial civilizations would have advanced by then if earthly beings had already accomplished this much. But as he looked around and failed to notice any individuals that appeared to live in relatively lower tax brackets, he concluded that extraterrestrials would have definitely found methods of equally distributing the prospects and wealth of technology— and that feat, he knew, would have defined alien’s society’s triumph over the earthlings. Looking back on the experience, Sagan eventually recognized that the fair proved humanity’s need to use science as a force for social progress, rather than social divide. Science, the future astronomer noted, was for the people.​

​​​​​​

Sagan demonstrates these factors, as he surrounded himself constantly with books that fueled his curiosity towards astrophysics, which manifested later in his endless dedication towards productive research— even when his experiments did not conclude in his favor. ​​​

​​​​

In Brooklyn on November 9th, 1934, Sagan was born to Sam Sagan and Rachel Molly Gruber Sagan. And they worked tirelessly to guarantee that they nurtured their son with ingenuity. Though not especially affluent, they managed to create an academic atmosphere in their home. Sagan recalls, “Both my father and mother read, there were wonderful arguments about politics and other matters, friends and visitors that I got to listen to [while] sitting in the corner”. Sagan’s parents evidently refused to dilute information that Sagan inquired about and did not censor their opinions to preserve his juvenility. They rather included him in conversations on advanced topics, and opened several doors for him to mature, sharpen his wit, and understand the dynamics of major political circumstances, such as the ongoing World War II, and the effects of classism. As a result, Sagan was meaningfully aware of political science in primary school. 

 

Sagan became a fast-ascending minor star of the space age in the 1950s, proposing exotic ideas about interstellar travel and extraterrestrials. However, his work in 1960 to “solve the mysteries of the high temperature of Venus (a massive greenhouse effect)” was his most notable idea of its time. These findings of Venus’ atmosphere caught the attention of Harvard astronomers, Donald Menzel and Fred Whipple, as Sagan’s work, which maintained that Venus was too hot to sustain surface water, directly challenged the theory they had established in 1955— that Venus was covered by a global ocean. Menzel and Whipple requested him to Harvard for a conference on planetary research, which Sagan accepted. Shortly after, Menzel and Whipple offered him joint posts at Harvard and the Smithsonian Astrophysical Observatory, however, Sagan asserted instead that he “wouldn’t accept anything less than assistant professor” . Eventually, Whipple agreed to write Harvard President Nathan Pusey on the matter, claiming Sagan would contribute “substantially to the scientific strength of the department”. In the mid-1970s, Sagan was driven to write The Dragons of Eden as he hoped to comprehend the odd paradoxes in his own life— reason and unreason, science and faith, desire and objectivity. In the book, Sagan proposes two models of the human brain, inspired by the neuroscientists Paul D.  Maclean and Roger Sperry. He expanded on their individual concepts, that the brain has three different layers — the neocortex, the limbic system, and the reptilian — and left and right halves with yin-yang qualities. The Dragons of Eden won the Pulitzer Prize, which certified Sagan’s status as a populist intellectual and highlighted his ability to write technical topics in a vivid and entertaining tone.

​

Sagan’s most well-known feat, however, is his popularization of astronomy, as he is often described as "the scientist who made the Universe clearer to the ordinary person”. He gave science a firmer mainstream platform by writing hundreds of comprehensible articles and over two dozen renowned books, and through his television show Cosmos. This 13-part series has been viewed by over 600 million people in more than 60 countries, and still counting. While this simple list of achievements may lead Sagan’s audience to believe in his natural intellect and academic privilege, the reality proves exceptionally complicated. Daniel Coyle argues in his book The Talent Code that success stems not from an innate talent, but a lifetime of sustained motivation, practice, and exposure to skilled teachers referred to as “master coaches.” Sagan demonstrates these factors, as he surrounded himself constantly with books that fueled his curiosity towards astrophysics, which manifested later in his endless dedication towards productive research— even when his experiments did not conclude in his favor. And he could not have managed any of this lasting effort had it not been for Hermann Joseph Muller’s support which allowed Sagan the opportunity to flourish his more unconventional ideas.

If You Wish To Make An Astronomer From Scratch, You Must First Ignite The Child Daniel

​​

Coyle argues in his book The Talent Code that ignition is the result of primal cues: subtle motivational prompts that an individual must consistently receive that encourage their work ethic and general interest in particular fields. Coyle stresses specifically that these primal cues must be continuous to guarantee sustained stimulation, as he writes, “[Talent hotbeds] contain complex collections of signals—people, images, and ideas—that keep ignition going for the weeks, months, and years that skill-growing requires”. Coyle's description of primal cues and “skill-growing” could be directly compared with the relationship between gas and car engines. A car can’t run forever on a single gallon or two of gas; it must be repeatedly filled to travel longer distances. Thus Coyle argues that an individual requires “collections of signals”, or primal cues, throughout their life to maintain their interest and motivation to pursue that interest. Without these cues, the individual, much like a car without fuel, will hardly scrape the surface of their skills. However, these cues aren’t very simple. The process of being ignited appears as a simple ‘if, then’ statement, however, the then quotient must always convey the idea of better get busy . Thus the primal cue must be exciting— it must convince an average individual that there is an area worth becoming extraordinary in. It must introduce a stellar idea or open a door to a secret club of elite information that tempts its audience beyond any other non-committal, manageable club. Daniel Coyle thereby asserts that ignition relies on the constancy and force of primal cues. 

​

Carl Sagan’s door to the secret club of astronomy was unlocked primarily by books. Naturally, Sagan was not born with an astronomer’s mind, nor did he always have an interest in science beyond what his standard school classes taught him. However, in William Poundstone’s biography, Sagan manages to recall how the stars had always both appealed to and maddened him in his childhood, as he could not decipher their reason for existence beyond being glowing baubles for young Brooklyn boys to admire. Poundstone writes, “The uselessness of these [stars], way up in the lovely night air, invoked a sense of melancholy. Carl went to the Eighty-fifth Street library and demanded a book on stars … It opened a world of enchantment”. One of the first primal cues in Sagan’s life was evidently that specific experience. There was the original cue of “The stars don’t make sense to me, better get busy.” Which eventually led into the “Astronomy’s nuances are fascinating, better get busy.” One primal cue naturally led to the other—which is an observation of Coyle’s concept of continuous ignition in practice. This experience not only expanded his world of knowledge but also expanded his general enthusiasm towards learning. However, this ignition was continued much later in his education, once again by an enlightening book, as Poundstone writes, “Sagan credited the book [Interplanetary Flight] as being a ‘turning point’ for him. It reinforced the still-novel idea that rockets to the planets would revolutionize the science of astronomy … Carl now realized that calculus was good for something … Fired by the Clarke book, he discovered the then-flourishing British school of scientist-popularizers”. After first realizing his initial interest in astronomy, Sagan still likely required another push to fully immerse himself in that area. And it’s also likely that he required a primal cue that was almost larger than life, that transcended his previous understanding of astronomy and introduced him to the wider breadth of information that science and math had to offer. Thus, Sagan found an exciting and convincing primal cue in Interplanetary Flight, as it not only gave his motivation to study stars a second wind, but it excited him by absolutely exceeding expectations. As Coyle states, a person must experience a variety of primal cues throughout their education and career. Naturally, it’d be difficult for any primal cues to have a lasting effect on a person if they are not stimulated accordingly. Sagan, however, was constantly witnessing revolutionary science throughout his life. During a broadcast entitled “A Celebration of Carl Sagan”, James H. Billington remarks, “Carl was born at the ideal time, he was a person for his time because he was there to be our guide through the initial exploration of our solar system. As he said and wrote many times, ‘There is only one generation that could begin when the planets and their moons were simply faint points of life and could watch each of them emerge as a true place with its geology and perhaps biology as well’”. Sagan’s luck at being “born at the ideal time” proves that he grew up and developed his career and interest in astronomy in a very stimulating environment. Had Sagan’s ignition been sparked just a generation before, or a generation after, he wouldn’t have felt as invigorated to hone his mind towards the singular subject of space travel. However, because he experienced a transformative period in astronomy, in which books such as Interplanetary Flight and especially detailed books on stars were most relevant and popular, his ambition only grew with humanity’s understanding of space. He could have turned on the television or strolled through the library, and encountered multitudes of primal cues. It would have been more difficult to avoid being ignited. It’s therefore apparent that Carl Sagan experienced constant primal cues in his life, exemplifying Coyle’s argument for ignition.

However, a master coach's duties extend beyond lesson plan adaptability. It is equally for the coach to have their own successes and failures in their career they intend to instruct their student, in a feature Coyle defines as  "a matrix".

​​​​

Daniel Coyle regards the concept of deep practice as meaningful, stimulating efforts to consistently improve specific weaknesses. To illustrate this, he references a study done to catalog the intellectual development of rats. Bill Greenough from the University of Illinois had created three groups of rats, each in varying conditions. The first group of rats was completely isolated from one another, inside empty shoeboxes. The rats in the second group were raised alongside each other, again in empty shoeboxes. And the third group was surrounded by other rats, while also given piles of toys to play with. After a few months, Greenough measured the synapses, or neuron pathways, in the rats’ brains, and found that the third group’s number of synapses had increased by 25% compared to the rats from lesser environments. From this, Coyle understood that an enriching environment breeds individuals of exceptional intellectual prowess. If a person is given the chance to exercise basic intellectual skills, they will have a better handle on certain critical thinking skills than a person who hasn’t. This is because they’ve devoted a ridiculous amount of time on certain subjects, which has allowed them to hone their minds toward those subjects, grooming themselves extraordinarily in that direction. However, Coyle also argues that simply practicing for a considerable amount of time is not sufficient in this endeavor; it’s necessary that the individual deliberately learns from their mistakes. Coyle writes, “Deep practice is not simply about struggling; it’s about seeking out a particular struggle”. In this quote, Coyle highlights that thoughtful failure allows a person to identify and target weak points to improve upon them. For example, if a baker attempts to make the fluffiest sponge cake, however the result is a flat and dense mass of batter, they have two options. They could either shy away from the failure and vow off sponge cakes for the rest of their career, or they could analyze their shortcomings: revise and try again. From this, they’d eventually recognize that they had failed to mix out the air bubbles in their egg whites. And once they’d corrected this error, they’d be at least one step closer to creating the fluffiest sponge cake in existence. This idea of deliberate failure and stimulating efforts to improve is highlighted by Coyle in his definition of deep practice. Carl Sagan was raised with a mindset that prompted him to not avoid failure and correction. In his biography of the astronomer, William Poundstone provides an anecdote in which young Sagan’s experiment did not at all result as intended. Poundstone writes, “Following instructions in the [chemistry] set’s manual, Carl and Lu performed an experiment involving the ‘chlorine ring.’ It blew up, making a mess of the room. Lu’s sister narrowly escaped injury. Rachel refused to punish Carl. She surveyed the devastation and then announced simply, ‘These things happen when scientists do experiments’”. It’s important to note that Rachel, Sagan’s mother, encouraged this type of failure in her son. She accepted it as an occupational hazard when you’re a genius, and thus never dissuaded him from risking failure to develop an experiment. Consequently, Sagan naturally understood there was no shame in failing plenty of times as long as you manage to grow and learn from your mistakes. These lessons would carry on with him late into his career, as Sagan comments in his book The Demon-Haunted World, “science has a built-in, error-correcting machinery at its very heart. Some may consider this an overbroad characterization, but to me every time we exercise self-criticism, every time we test our ideas against the outside world, we are doing science”. Sagan’s idea of "error-correcting machinery" implies that failure is expected in the scientific process. He encourages scientists to embrace failure, because all failure provides a natural path to improvement. Thereby it’s evident Sagan had a strict mindset that recognizing and addressing mistakes are fundamental to intellectual development, and no one should ever renounce their mistakes and shun their failed ideas. When someone refuses to grow from their failure, they force themselves to start over from square one, building up completely new ideas from scratch— ideas that will naturally fail as well. However, Sagan, as he was unafraid of correction, refused to start over, and instead took his failed experiments as necessary research that would lead him to the correct answer. So he constantly built himself up and ultimately rose far above his peers. From this, one could easily gather that Sagan consistently practiced deliberate failure to improve upon his potential weaknesses. 

​

Carl Sagan, much like the rats in Greenough’s experiment, surrounded himself in a constantly stimulating environment during his education, taking every opportunity to develop his understanding of astronomy, albeit at the expense of basic human necessities. Coyle details that deep practice solely occurs in intellectually gratifying circumstances. Sagan evidently was subject to such circumstances during his time at university. Abrahamson, his roommate, comments in William Poundstone’s biography, “‘He never cleaned up; he expected us to cook for him; he was just a brat’ … Unencumbered by trivialities, Sagan could devote extra time to his more speculative interests. One of them was UFOs … All summer long, Abrahamson would drag himself into the apartment after a long day’s work and Sagan would bug him to go out and look for UFOs”. Sagan prolonged his studies, to his roommate's dismay, by turning any and all of his spare attention towards scientific essays and field research. While this may seem an excuse to avoid his chores, it may also be interpreted as Sagan’s habit to disassociate from normalcy and triviality to absolutely captivate himself in larger concepts. He focused on one thing alone, sacrificing the development of many other skills, and thus became extremely skilled at doing that one thing. There was not a moment of his life that was not occupied with astronomy, and as a result he became a brilliant astronomer, among the best of his generation.

Somewhere, An Incredible Coach Is Waiting To Be Known 

​

Daniel Coyle illustrates the character of a master coach as someone able to respond to every individual student’s needs. Coyle found common attributes of master coaches in his research, the most telling of these being their extreme sensitivity: they prioritize listening over talking, and streamline productivity by offering solely small, specific commentary. What Coyle primarily emphasizes in this description is the master coach’s ability to adapt their lessons to the student’s needs. If they don’t, their ideas will be completely lost in translation and the student will walk away from a fruitless class. Coyle therefore states that a master coach is someone who can easily alter their lessons to suit their student, so everything can be most effectively communicated. However, a master coach’s duties extend beyond lesson plan adaptability. It is equally necessary for the coach to have their own successes and failures in the career they intend to instruct their student in, a feature Coyle defines as “a matrix.” He describes, “Many of the coaches I met shared a similar biographical arc: they had once been promising talents in their respective fields but failed and tried to figure out why”. Coyle emphasizes here that a master coach needs extensive wisdom of their field; and wisdom, unlike basic knowledge, comes from firsthand experience. They must have themselves failed before they could guide their students from failure, and they must have themselves succeeded before they could teach their students what path is most successful. Their pupil then could only build productively upon their coach’s legacy. A master coach is therefore a sensitive mentor who is able to respond meaningfully to each student’s needs, and then pass on their own lessons from experience. Carl Sagan found a master coach in Hermann Joseph Muller, possibly the first scientific mind to empathize with Sagan’s theories on extraterrestrial life. During his career, Sagan faced negative reception by his fellow academics at mainly Harvard due to his seemingly lofty ideas about interplanetary life forms. Many lecturers named him “self-aggrandizing” after the release of his book entitled Intelligent Life In The Universe— this public reaction contributed heavily to him being ultimately denied tenure at Harvard. One would have found it easier to abandon their extraterrestrial theories in the face of such resistance, however Sagan was saved from this fate as he managed to connect with Muller. What made Muller an especially perfect mentor for Sagan was the level of similarity in their characters. Keay Davidson writes in his biography, “Muller was not one to crush unorthodox ideas: he had many of his own”. Evidently, Muller was able to collaborate and develop Sagan’s ideas because of how invested in the topic he inherently was. It would have been unlikely for Sagan to find someone who would listen to his theories; and when he did, it would have been a person who didn’t exactly agree with him or care for a serious discussion. But Muller wasn’t solely a listening ear— he was an actual peer. Davidson expands on this idea as he writes, “Sagan appreciated Muller because he didn’t dismiss the possibility that there might be life on other planets … Some mentors try to suppress their young charges’ dreams and redirect them in more ‘productive’ directions. But Muller listened happily as Sagan pontificated about extraterrestrial life and space travel”. Much like Jenson’s adaptive teaching style, Muller perfectly behaved as the exact type of mentor that Sagan needed. After being denied tenure from Harvard by his academic adversaries who believed his ideas to be unnecessarily unconventional, Sagan needed someone willing to listen as a scientist, and view his ideas as science. Had Sagan met any other mentor, his “creative” ideas would have been stifled and discouraged, but Muller permitted them space and time to mature. 

​

They honor Sagan as an oracle of scientific credibility and inspiration— an individual with whom they may share their most unorthodox ideas, theories, and dreams. He was absolutely one in billions and billions. 

​​

Hermann Joseph Muller observes Coyle’s virtue of a “matrix,” as he evidently managed to guide Sagan’s career with advice gathered from his own. During his work in Moscow, Muller frequently butt heads with the chemist A.I. Oparin, as they disagreed over the key issue of whether life begins as a gene or a cell. Muller proposed that the earliest life forms were large molecules able to reproduce independently, a theory referred to as the “naked gene” theory, while Oparin maintained that it is cells that come first. Ultimately, this matter was not settled, as neither Muller nor Oparin managed to find a convincing argument to discredit the other’s theory. Years later, Muller noticed that Sagan’s research was beginning to cross into that territory, so he made sure to guide Sagan appropriately. Keay Davidson writes in his biography, “Muller had been quick to point out to [Sagan] the crucial problem in Oprain’s theory … Sagan then became an enthusiast for Muller’s ‘naked gene’ theory, which would, in fact, be the basis of Sagan’s first published scientific paper”. This quote proves that while Muller may have failed to appeal to Oparin himself in previous years, he managed to spark a similar flame in Sagan, however with stronger ideas. This exchange is reminiscent of the saying, “X walked, so Y could run.” Muller managed to identify his shortcomings and effectively squashed them out of Sagan, preparing him to claim the victory that had eluded him during the height of his career. Thus Muller is a prime example of Coyle’s theory of a master coach’s “matrix,” as he took his career, analyzed it, and provided thoughtful advice to his pupil. Carl Sagan is internationally, and possibly universally regarded as an irreplaceable individual in the world of astrophysics. His dedication to his studies, endless motivation, and rousing education gave him the fuel he needed to reach heights unimaginable by the average science enthusiast. Sagan’s legacy continues on even today with his most influential works being frequently revived. For example, the significant success of his PBS series, Cosmos, led Family Guy creator Seth McFarlane to reinvent the show’s concept with Neil deGrasse Tyson as the new host in 2014. This reboot served as the highest rated PBS series for several years after its release. However, McFarlane continued to platform Sagan’s studies by establishing “The Sagan Archive” at the Library of Congress, in which hundreds of his papers were made available to researchers. These two acts of preservation provide a vivid image of the celebrity scientist’s meaningful career, evident as ordinary people have begun sending letters to Sagan’s former office at Cornell. They honor Sagan as an oracle of scientific credibility and inspiration— an individual with whom they may share their most unorthodox ideas, theories, and dreams. He was absolutely one in billions and billions.
