Life and achievements
Early life
Richard Feynman was born to Lucille and Melville Feynman on May 11, 1918, in New York City, United States of America. From a young age, he was fascinated with engineering and science and spent most of his time playing with radios and conducting experiments in his homemade lab. Richard's father, who used to encourage him to ask questions and not conform to the norms set by society, had a significant influence on him.
Feynman had always been a brilliant student, especially in mathematics and science, even in his elementary and high school years. Although he scored an IQ of 125, which he later said was only 'merely respectable,' he was a passionate man who taught himself advanced mathematics. He graduated from Far Rockaway High School, where he was a bright student in science and mathematics; he won the New York University Math Championship in his last year of high school.
Feynman was not admitted to Columbia University because the university had a limited admission of Jewish students, so he entered the Massachusetts Institute of Technology. He first entered math as his major but soon changed to physics because he felt that physics was more suitable for exploring nature. At MIT, he produced his first papers and derived what is now called the Hellmann-Feynman theorem.
Feynman continued his education at Princeton University, where he was to do his Ph.D. under the guidance of John Archibald Wheeler. His doctoral thesis, "The Principle of Least Action in Quantum Mechanics," can be considered the starting point of his further research in quantum electrodynamics. He also married his high school sweetheart, Arline Greenbaum, while still studying at Princeton, even though she was a sickly woman who would die soon, further proving his love.
Legacy
Richard Feynman greatly impacted many areas of science and many people's lives. His contribution to quantum electrodynamics earned him the Nobel Prize and changed how physicists look at particle interactions. Feynman diagrams proved a helpful tool still used in theoretical physics today.
Feynman did not only contribute to the scientific research. He was a great teacher and could explain complex concepts in simple terms, making him popular among the academic community. "The Feynman Lectures on Physics" is still one of the most influential books that enlightens and motivates students worldwide. He has written several autobiographical books and given many recorded lectures, which have helped make physics enjoyable for many people.
Feynman's participation in the Space Shuttle Challenger disaster investigation is a clear example of his adherence to the principles of scientific excellence and the protection of human lives. His re-creation of the O-ring failure was one of the critical events of the investigation, which proved that openness and truth are crucial for scientific analysis.
Aside from his scientific contributions, Feynman's personality and way of looking at the world earned him fame. He indulged in many activities, such as playing the bongo drums and cracking safes, and thus portrayed an adventurous and creative spirit. His passion for knowledge and discovery is an example to many people in the scientific fraternity and society.
Feynman's works can also be seen in quantum computing and nanotechnology. The problems and ideas he faced and came up with in these areas are the foundation for future technologies and show his progressive thinking. The Feynman Prize in Nanotechnology, awarded in his honor, is given to those who have made significant contributions to the field of nanotechnology, thus sealing his legacy in science and technology.
Milestone moments
Jun 19, 1942
Marriage to Arline Greenbaum
Richard Feynman married his high school sweetheart, Arline Greenbaum, on June 29, 1942, even though she was a tuberculosis patient. This personal commitment was evident in his love for her and his dedication to her until her death, even while he was studying for his Ph.D. at Princeton University. Their wedding was straightforward, showing how Feynman managed his time between work and family life as a young physicist.
This gave Feynman strength and motivation even as he struggled through his academic and work life. It is for this reason that Arline's sickness and death impacted him deeply and influenced his outlook on life, love, and death. The notes he wrote to her about his love and regrets were closed and opened only after his death; the extent of his feelings and how their passion affected him were shown.

The Manhattan Project and Los Alamos
In July 1945, Richard Feynman contributed to the Trinity test, the first atomic bomb explosion, as a member of the Manhattan Project in New Mexico. Working under Hans Bethe in the Theoretical Division, Feynman helped in the theoretical analysis of the bomb and the actual building of the bomb, showing Feynman's versatility in theoretical and practical physics.
Feynman's job at Los Alamos meant that he was engaged in calculations and thinking out of the box, which was crucial for the project. His ability to express himself, his ideas well, and his practical nature made him a good leader among his peers. His work at Los Alamos, his contact with the prominent scientists of the time, and the nature of the work he was engaged in shaped his career and outlook on science.

Quantum Electrodynamics Breakthrough
Feynman published his papers on QED in October 1949. These papers introduced a new concept in the interactions of particles and light. They also presented Feynman diagrams, a way of drawing the processes that changed the course of the field and became a standard in the use of physicists. He clarified several questions in QED and received the Nobel Prize in Physics in 1965.
Using Feynman diagrams made it easier to calculate particle interactions, and the process, which had been quite complicated before, became much more accessible. This innovation not only helped develop theoretical physics but also helped popularize the subject among students and researchers. Feynman's work on QED is one of his most important scientific contributions and further affirmed him as a great physicist.

Nobel Prize in Physics
Richard Feynman received the Nobel Prize in Physics in June 1965, with Julian Schwinger and Shin'ichirō Tomonaga, for their work in quantum electrodynamics. This great honor acclaimed Feynman for his creative work in the field, especially the path integral formulation and Feynman diagrams. The Nobel Prize recognized him as one of the most influential scientists of his generation for his contribution to the study of particle physics.
The award helped Feynman gain recognition and more chances to contribute to the development of physics. His speech during the acceptance of the prize was as humble as he is, and he recognized that science is a team effort. The Nobel Prize also helped him speak for scientific integrity and education and reach more people.
