Robert Oppenheimer - life phases

Robert Oppenheimer’s childhood:

Robert J. Oppenheimer was born on April 22, 1904, in New York City to Jullis Seligmann Oppenheimer, a German immigrant who had established a textile importing business, and Ella Friedman, a painter. Oppenheimer has a brother and a sister. Since childhood, Oppenheimer has been a voracious and fast learner. He was extremely socially awkward as a teenager, so he didn’t have real friends and was the loneliest person.

Oppenheimer did his schooling at the Ethical Culture Society School. He completed his third and fourth grades in the same year and his eighth grade in a half-year. When he was 5, he went on a vacation to his grandfather’s house in Germany. There, he became enamoured with the collection of minerals his grandfather had given him. And he developed a lifelong obsession with rock collecting. When he was 11, he joined the New York Mineralogical Club, and a year later he presented his first scientific paper.

J Robert Oppenheimer Education:

Oppenheimer’s undergrad years began at Harvard University in the 1920s. At that time, he was especially interested in chemistry and earned a degree in chemistry from Harvard University. Everyone who studies science at Harvard University should definitely study literature, history, and philosophy as well. During this time, Robert read the English version of the Bhagavad Gita, a Hindu scripture. Later he learned Sanskrit to read it in the original language.

Robert found Percy Bridgeman’s experimental physics classes at Harvard to be appealing. In 1924, Oppenheimer was admitted to the Cavendish Laboratory at the University of Cambridge. He requested permission from Ernest Rutherford to work at the Cavendish Laboratory. Bridgman gave Oppenheimer a recommendation that made it clear that Oppenheimer’s clumsiness in the laboratory meant that his forte was not experimental but theoretical physics.

But Oppenheimer got a good opportunity to work with a research team under the leadership of J.J. Thomas, who discovered the electron in 1897. In 1926, Oppenheimer left Cambridge and entered the University of Gottingen to pursue a PhD in physics under the supervision of Max Born.

Oppenheimer’s doctoral studies primarily focused on quantum mechanics; he delved into theoretical aspects, exploring the mathematical formulations and conceptual frameworks that underpin quantum theory. And finally, in 1927, at the age of 23, Oppenheimer obtained his PhD in physics.

J Robert Oppenheimer and the Manhattan Project

The United States started the Manhattan Project during World War II to create nuclear weapons and the atom bomb. Oppenheimer played a central role in the development of the atomic bomb during the Manhattan Project. In 1942, the United States government appointed Oppenheimer as the scientific director of the Manhattan Project.

Making good use of his theoretical physics knowledge, he correctly guided the team through the challenges faced while developing the atom bomb, including the fundamental understanding of nuclear reactions, neutron moderation, and critical mass calculations.

Under Oppenheimer’s leadership, on July 16, 1945, the Manhattan Project successfully test-fired the first atomic bomb under the code name “Trinity” in the New Mexico desert. The atomic bombs developed in this Manhattan project were dropped on Hiroshima and Nagasaki. The devastating impact of these bombings hastened Japan’s surrender, effectively ending World War II.

J Oppenheimer and the Bhagavad Gita

Oppenheimer has a profound connection with the Bhagavad Gita, a Hindu scripture. He was introduced to the Bhagavad Gita when he was studying at the University of Gottingen in Germany by his friend Arthur W. Ryder. He devoted a lot of time to studying its philosophical texts, which were particularly fascinating when it came to duty, moral responsibility, and the nature of life and death.

Oppenheimer’s work on the Manhattan Project is closely related to some of the lessons in the Bhagavad Gita. In a conversation with journalist Richard L. Stokes after the Trinity Test, he famously quoted a verse from Chapter 11, Verse 32, of the Bhagavad Gita: “Now I am become Death, the destroyer of worlds.” The quote reflects the profound impact it had on him during the development of the atom bomb.

J Robert Oppenheimer I am become death speech

This verse has a wider context in the Bhagavad Gita, where Krishna gives the warrior Arjuna profound teachings on the importance of fulfilling one’s duty regardless of the results. By invoking the Bhagavad Gita, Oppenheimer symbolically connected his role in the creation of the atomic bomb with the moral dilemmas that Arjuna faced during the war.

Discoveries of Robert J Oppenheimer

Apart from being the director of the Manhattan Project, he made significant discoveries and contributions to the field of physics. His discoveries and contributions spanned various areas of physics, from astrophysics to quantum mechanics. Here are some of his notable discoveries and contributions to physics:

Oppenheimer-Phillips Process:

Together with his student Melba Phillips, Oppenheimer developed the Oppenheimer-Phillips process, which explained the mechanism behind nuclear reactions in stars. This process played a key role in developing our understanding of stellar nucleosynthesis.

Oppenheimer-Volkoff Limit:

Oppenheimer, along with physicist George Volkoff, made groundbreaking contributions to the study of neutron stars. They proposed the Oppenheimer-Volkoff limit, which describes the maximum mass a neutron star can sustain before collapsing into a black hole under the influence of gravity.

Quantum Tunnelling:

Oppenheimer’s work in quantum mechanics contributed to the understanding of quantum tunnelling. He explored the phenomenon of cells overcoming potential barriers, leading to insights into the behaviour of subatomic particles.

Oppenheimer-Snyder Model:

In 1939, Oppenheimer, along with his student Hartland Snyder, published a groundbreaking paper exploring the gravitational collapse of massive stars. Their model, called as the Oppenheimer-Snyder model, assumes that a massive star collapses under its own gravity, forming a dense region.

Oppenheimer-Phillips Effect:

Oppenheimer and Phillips also made significant contributions to the theory of electron-positron pair production in high-energy gamma-ray interactions. This phenomenon, known as the Oppenheimer-Phillips effect, has helped explain the formation of particle-antiparticle pairs under extreme conditions.
