"Just as the rebellious Greek god Prometheus stole fire from Zeus and gave it to humanity, Robert Oppenheimer bestowed upon us the fire of the atomic bomb. But when he tried to control it, when he tried to warn of its terrible dangers, the powers that be, like Zeus, were enraged and punished him."

This is a quote from the preface of the book American Prometheus by Kai Bird and Martin Sherwin. Prometheus did not remain unharmed. He was chained to the Caucasus Mountains and had his liver pecked daily by an eagle. Oppenheimer became the most conspicuous victim during the peak of McCarthy-era anti-communist hysteria. The U.S. government doubted his loyalty when he advised reducing dependence on nuclear weapons. They put him on trial and subjected him to all kinds of humiliation. Before the blood on his hands could even dry...

Director Christopher Nolan is a filmmaker who focuses on the emotion of 'abandonment.' In his representative works such as Interstellar, Memento, and Inception, he expressed anger at fading light. The enemy, once represented by time, shifts to ideology and thought in Oppenheimer. It breaks the courageous conscience befitting his fame.

Perhaps it is an inevitable tragedy. Knowledge grows fiercely, and the influence of mass media continues to expand. Communities become closed off to protect themselves. From the time Oppenheimer oversaw nuclear weapons at Los Alamos, he warned against excessive specialization and fragmentation. To him, the community was a fortress and a sanctuary that enabled belonging and mutual dependence. A place where public intellect could blossom...

"If someone says they see the world differently from us, if they say what we find ugly is beautiful, perhaps we will feel uncomfortable and leave the room. But this is our weakness and flaw. If that world and its people are more right than us, and if they mean well for us, then let us adopt their standards and no longer seek comfort elsewhere."

'By the way,' here is some useful information delivered in a somewhat disorganized manner. It’s a tip for enjoying the movie more interestingly.

*Oppenheimer was born on April 22, 1904, into a wealthy and liberal family in New York. His father, Julius, immigrated from Germany to the U.S. in 1888 at the age of seventeen and achieved great success in the fabric import business with relatives. His mother, Ella Friedman, was a talented painter. The family had immigrated from Germany to Baltimore in the 1840s.

*Both of Oppenheimer’s parents were accomplished in the arts, especially music.

*Oppenheimer had two younger brothers. One died at birth, and the other was named Frank.

*The Oppenheimer family lived in a spacious and cozy 11th-floor apartment overlooking the Hudson River. They also had a summer house on Long Island Bay Shore. Reflecting on his childhood, Oppenheimer recalled, "I never experienced pain or hardship in any form."

*Van Gogh’s works hung on the walls of the Oppenheimer home. The decorations were his mother’s doing. She had a disability in her right arm and always wore gray silk gloves. Acquaintances remembered her as nervous and emotionally fragile, always with a sad expression.

*The Oppenheimer family actively participated in the Ethical Culture Movement started by Felix Adler in 1876. Oppenheimer naturally enrolled in the Ethical Culture School, an institution that pursued high academic standards and liberal educational ideals. It was ideal for educating him without making him an outsider, as he was excellent academically and intelligent but appeared somewhat anxious. Oppenheimer graduated from the Ethical Culture School in February 1921 and entered Harvard the following year in 1922. The one-year gap was due to severe illness. He traveled Europe and rested sufficiently. In the summer of 1922, he also traveled the American Southwest. He fell in love with the New Mexico landscape he visited at the time.

*During college, Oppenheimer intended to become a mining engineer. Although he majored in chemistry, he audited other subjects as well. He took twelve courses annually instead of the usual eight, which allowed him to graduate in three years.

*In his senior year, Oppenheimer focused on research in Bridgman’s laboratory on solving pressure problems in metallic conductors. While he valued the understanding and research experience gained through repeated experiments, he felt experimental science did not suit his aptitude. Nevertheless, after graduating from Harvard, he entered Cambridge University. Oppenheimer struggled with the overall culture at Cambridge, the embarrassment caused by research failures, and the distancing of friends from Harvard who had married. Patrick Blackett, three years his senior, succeeded as a young experimental physicist, teaching him and causing Oppenheimer to fall into depression as he saw some colleagues succeed in experiments. He even placed a poison apple, suspected to contain cyanide, on Blackett’s desk. Fortunately, it was discovered, and Blackett was unharmed. Oppenheimer was reported to the school authorities and nearly expelled. Thanks to his parents’ intervention and a promise to undergo counseling, he narrowly avoided expulsion.

*Oppenheimer was always emotionally unstable. His close friend Isidor Rabi described him as "a naturally weak person." American theoretical physicist Silvan S. Schweber wrote in his book Einstein and Oppenheimer: "Oppenheimer constantly threw himself into dangerous situations. Like sailing through a storm, like a reckless driver, like an unprepared ascent, he clashed endlessly with the society around him. He never learned how to be healthy. Beneath his wisdom, arrogance, and seemingly dry emotions lay deep anxiety, especially doubts about his own creativity."

*Having overcome crisis, Oppenheimer decided to become a theorist. The year 1925, when he devoted himself to research, was a pivotal year of rapid change in theoretical physics. Werner Heisenberg’s matrix mechanics was published, followed by research results from Max Born and Pascual Jordan introducing communication laws for anharmonic oscillators. The next year, Erwin Schr?dinger’s work introduced wave mechanics. As a result, research on atomic phenomena was revitalized, laying an analytical foundation for new mechanics. Oppenheimer remarkably quickly absorbed the rapidly evolving research. Notably, in May 1926, he published his first paper explaining the quantum physics of molecular band spectrum periodicity and gaps. In July of the same year, he published a paper on the continuous spectrum and wave normalization of the hydrogen atom.

*In 1926, Oppenheimer moved to G?ttingen, Germany, to conduct research with Max Born. They aimed to explain atomic motion using the new framework of wave mechanics. He was the first scientist to prove that previous quantum theories were incorrect through a new quantum physical explanation of X-ray emission.

*Oppenheimer was confident in G?ttingen. At seminars led by Born, he was unbothered by friction with other participants. Whenever someone disagreed with him, he would go up to the podium and write his thoughts on the blackboard. Participants found this unpleasant. After the seminar, they sent notes to Born threatening not to attend again unless Oppenheimer’s behavior was restrained. Born, lacking the courage to speak directly to Oppenheimer, left the notes on his desk. Seeing them, Oppenheimer began to restrain himself.

*Theoretical physics in the U.S. started late. Systematic research institutions were established only after experimental physicists introduced quantum physics in the 1920s. Oppenheimer established his own research institution at Berkeley and was able to pursue his theoretical interests in the 1930s.

*When Oppenheimer first taught graduate courses at Berkeley, students were bored by the level. However, years later, his classes became very popular. Students who took his quantum physics courses were captivated by the beauty of a new world. Hans Bethe’s 1966 tribute to Oppenheimer includes the phrase: "The most essential element that illuminated Oppenheimer’s classes was sophistication. He always knew what the important problems were. He truly lived with those problems, struggled for answers, and communicated with his students."

*Oppenheimer did not simply lecture unilaterally. He engaged with students personally through collective research investigations. He believed creativity emerged through collective effort. Oppenheimer emphasized, "What we do not understand ourselves, we can explain through each other."

*Oppenheimer integrated quantum physics and special relativity to analyze complex experimental data from cosmic ray experiments. This made him a leading figure representing a new type of theoretical physics. However, limited experimental possibilities meant he was not as recognized by quantum physics pioneers like Paul Dirac, Heisenberg, or Schr?dinger.

*The 1930s were a turbulent era. Economically, it was the Great Depression, and the Nazis rose to power in Germany. Due to Hitler’s pathological hatred of Jews, German scholars began emigrating to Britain, the U.S., and elsewhere. Spain was engulfed in civil war, and Stalin’s purges were underway in the Soviet Union. Oppenheimer’s safety was also at risk. He supported the Spanish Republic as his relationship with his lover Jean Tatlock deepened.

*Oppenheimer married Kitty Puening Harrison in 1940. Her ex-husband, Joe Dallet, was a communist who died in the Spanish Civil War.

*When World War II broke out in September 1939 and France fell in June the following year, Oppenheimer believed Western civilization was in grave danger. He thought Britain and the U.S. could fall at any time. He openly stated, "We must defend Western civilization from the Nazi threat."

*In January 1939, Oppenheimer paid close attention to news that Otto Hahn and Fritz Strassmann had succeeded in nuclear fission. He did not believe it immediately. He told the Berkeley research team that nuclear fusion reactions were impossible. But the next day, after witnessing a fusion reaction demonstration by colleagues Luis Alvarez and Ken Green, he changed his mind. Alvarez recalled: "I invited Oppenheimer and showed him natural alpha particle pulses and spikes about twenty times larger caused by nuclear fission on an oscilloscope. In less than 15 minutes, he agreed with everything I said and predicted that increasing the number of neutrons could increase uranium fission, leading to explosive energy. I was amazed by his quick judgment, and it was accurate. As a scientist, his attitude was excellent. Even if it was his own claim, once proven wrong, he gratefully accepted the result and immediately set new goals."

*The concept of a nuclear fission bomb was first proposed by a British research team led by Otto Frisch and Rudolf Peierls. In the summer of 1942, numerous theorists, including Oppenheimer, began focusing on this topic. Oppenheimer organized conferences to lead research on the theoretical design and utility of the atomic bomb. The research team supported Frisch and Peierls’ findings while obtaining results on the amount of U-235 needed to create a more efficient bomb. When given the opportunity to study U-235 and U-238 from natural uranium, Oppenheimer gladly accepted. He was tasked with planning faster nuclear fission and bomb design. Leslie Groves, authorized by President Franklin Roosevelt, took charge of the bomb project and not only oversaw the entire project but also centralized all nuclear research at the Los Alamos Laboratory in New Mexico as Oppenheimer had proposed.

*In October 1942, Groves traveled to Berkeley to personally observe isotope separation experiments of U-235 and U-238 conducted using the cyclotron at the Lawrence Radiation Laboratory. Oppenheimer was deeply impressed by Groves’ outstanding comprehension. At the time, Groves was considering whether to entrust Ernest Lawrence with overall responsibility for the bomb development.

*Despite Groves’ past associations with left-wing figures in the 1930s, he appointed Oppenheimer as the director of the Los Alamos Laboratory. He valued Oppenheimer’s unique scientific and technical achievements and the trust he commanded among peers. Of course, underlying this decision was the judgment that Oppenheimer would be easier to control than Lawrence. Unlike Oppenheimer, Lawrence was a confident person who had even won a Nobel Prize, making him harder to manage.

*Groves recognized Oppenheimer’s physics insight and his combination of charismatic leadership and absolute obedience to authority. Knowing Oppenheimer was a loyal patriot who loved his country, Groves exercised decisive judgment by overlooking his past. The Los Alamos Laboratory, led by Oppenheimer, opened in spring 1943.

*Physicists who worked at Los Alamos during the war often recall that time as a utopia. They were united by a resolve to protect Western democratic civilization from Nazi Germany’s attack. They believed they must not fall behind Germany, which had started nuclear weapons development two years earlier. They were well aware that if their project succeeded, it would mark a new chapter in human history. When the first atomic bomb test, Trinity, was successfully conducted, they believed it would help build peace.

*The explosion test took place on July 16, 1945, in the Jornada del Muerto desert region of central New Mexico. The name Trinity was coined by Oppenheimer himself. It was inspired by a line from John Donne’s poem beginning with "the Godhead triple," and also drew inspiration from the Hindu trinity of Brahma (the creator), Vishnu (the preserver), and Shiva (the destroyer).

*Most scientists at Los Alamos agree that without Oppenheimer’s leadership, the bomb used on Japan could never have been completed on time. The responsibility placed on Oppenheimer’s shoulders was immense, and the honor he received was well deserved. The guilt for having contributed most to creating the atomic bomb was also inevitably the greatest.

*Los Alamos was isolated from other areas. Researchers shared life as members of a community rather than as individuals. They were immersed in an atmosphere like being under a spell, feeling like one large community. Oppenheimer played the biggest role in forming this. He sought to identify himself with research and experiments, reality and ideals, individuals and community, and the nation.

*Author Torp, who wrote Oppenheimer’s social biography, viewed that as Los Alamos’ organization became dynamic and complex, Oppenheimer’s charismatic leadership and authority also developed. To carry out the military mission of producing the atomic bomb, Los Alamos included scientists, engineers, military personnel, and experts from various fields. Oppenheimer’s authority and charismatic leadership played a decisive role in uniting them.

*Torp also paid attention to the complementary roles and relationship between Oppenheimer and Groves at Los Alamos. Groves was the actual project leader. Although authoritative, coercive, and militaristic in management style, he strongly supported Oppenheimer’s leadership, which emphasized consensus and fostered cooperation and camaraderie among scientists, engineers, and experts with an academic attitude. Groves understood that the collaborative work environment and research team created by Oppenheimer were ultimately under his own authority. Oppenheimer earned much respect by leading the atomic bomb development project without losing focus and embracing everyone. Groves acknowledged this leadership. Torp summarized: "Oppenheimer’s moral qualities and integrative knowledge excellently resolved conflicts between parties. He was a natural orator who could draw out agreements not yet reached."
