Sin-Itiro Tomonaga Net Worth

Sin-Itiro Tomonaga was a Japanese physicist born in Tokyo in 1906. He was awarded the Nobel Prize in Physics in 1965 for his work on quantum electrodynamics (QED), particularly for discovering the renormalization method. He was also responsible for suggesting the covariant formulation in quantum field theory and making QED uniform with the theory of special relativity. During the Second World War, his work was not recognized by the West, but after the war, he was awarded numerous honors, including the Order of Culture in 1952 and the Mikhail Lomonosov Gold Medal in 1964. He was also a professor of physics at Bunrika University, President of Tokyo University of Education, and Chairman of Japan Science Council. He was a strong advocate for using nuclear energy for peaceful purposes.

Biography/Timeline

1906

Tomonaga was born in Tokyo in 1906. He was the second child and eldest son of a Japanese Philosopher, Tomonaga Sanjūrō. He entered the Kyoto Imperial University in 1926. Hideki Yukawa, also a Nobel Prize winner, was one of his classmates during undergraduate school. During graduate school at the same university, he worked as an assistant in the university for three years. In 1931, after graduate school, he joined Nishina's group in Riken. In 1937, while working at Leipzig University (Leipzig), he collaborated with the research group of Werner Heisenberg. Two years later, he returned to Japan due to the outbreak of the Second World War, but finished his doctoral degree (from University of Tokyo) on the study of nuclear materials with his thesis on work he had done while in Leipzig.

1940

Tomonaga was married in 1940 to Ryōko Sekiguchi. They had two sons and one daughter. He was awarded the Order of Culture in 1952, and the Grand Cordon of the Order of the Rising Sun in 1976.

1948

In Japan, he was appointed to a professorship in the Tokyo University of Education (a forerunner of Tsukuba University). During the war he studied the magnetron, meson theory, and his super-many-time theory. In 1948, he and his students re-examined a 1939 paper by Sidney Dancoff that attempted, but failed, to show that the infinite quantities that arise in QED can be canceled with each other. Tomonaga applied his super-many-time theory and a relativistic method based on the non-relativistic method of Wolfgang Pauli and Fierz to greatly speed up and clarify the calculations. Then he and his students found that Dancoff had overlooked one term in the perturbation series. With this term, the theory gave finite results; thus Tomonaga discovered the renormalization method independently of Julian Schwinger and calculated physical quantities such as the Lamb shift at the same time.

2013

In the next year, he was invited by Robert Oppenheimer to work at the Institute for Advanced Study in Princeton. He studied a many-body Problem on the collective oscillations of a quantum-mechanical system. In the following year, he returned to Japan and proposed the Tomonaga–Luttinger liquid. In 1955, he took the leadership in establishing the Institute for Nuclear Study, University of Tokyo. In 1965, he was awarded the Nobel Prize in Physics, with Julian Schwinger and Richard P. Feynman, for the study of QED, specifically for the discovery of the renormalization method. He died of throat cancer in Tokyo in 1979.

2015

In recognition of three Nobel laureates' contributions, the bronze statues of Shin'ichirō Tomonaga, Leo Esaki, and Makoto Kobayashi was set up in the Central Park of Azuma 2 in Tsukuba City in 2015.
