Sin-Itiro Tomonaga's Birth Card: The 5 of Clubs

In the record

Shinichiro Tomonaga (朝永 振一郎, Tomonaga Shin'ichirō; March 31, 1906 – July 8, 1979), usually cited as Sin-Itiro Tomonaga in English, was a Japanese physicist. The birth-card coordinate for March 31 is the 5 of Clubs — a calendar position, not a forecast of the 1965 Physics prize.

The 5 of Clubs coordinate

Sin-Itiro Tomonaga's birthday maps to the 5 of Clubs (The Dynamic Innovator). Card Blueprints treats that as a 365-day coordinate: solar value = 55 − (2 × month + day), and the year is unused. It is not a prediction about a Nobel Prize and not a verdict on Sin-Itiro Tomonaga. The card's own language, quoted as system copy rather than biography: You pressure-test an idea in public and let the better one win.

Sin-Itiro Tomonaga in the public record

He shared the 1965 Nobel Prize in Physics with Richard Feynman and Julian Schwinger "for their fundamental work in quantum electrodynamics (QED), with deep-ploughing consequences for the physics of elementary particles". 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 laureate, 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.

Where the record meets the 5 of Clubs

A card is a calendar coordinate, not a cause. What follows sets one line of the card's own published language beside one sentence of the sourced record, paired by a documented rule. It is a resemblance offered for the reader to weigh — not a claim about Sin-Itiro Tomonaga, and not a forecast of a Nobel Prize.

Also on the record

1. Two years later, he returned to Japan due to the outbreak of the Second World War, but finished his doctoral degree (Dissertation PhD from University of Tokyo) on the study of nuclear materials with his thesis on work he had done while in Leipzig.
2. In Japan, he was appointed to a professorship in the Tokyo University of Education (a forerunner of Tsukuba University).
3. During the war he studied the magnetron, meson theory, and his super-many-time theory.
4. 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 quantum electrodynamics (QED) can be canceled with each other.

FAQ

What is Sin-Itiro Tomonaga's birth card?

The 5 of Clubs. March 31 maps to that card through the public Card Blueprints formula. The year of birth is not used.

Does a birth card predict a Nobel Prize?

No. These pages are coordinates, not fortune-telling. A birth card names a calendar day in a 52-card year. It does not forecast prizes, character, or fate.

Where do Sin-Itiro Tomonaga's dates come from?

Birth date 1906-03-31 is the Nobel Prize API v2.1 day-precision date, verified against Wikidata P569 (CC0, day precision, Gregorian preferred). The two sources match. Year-only Nobel dates and Nobel↔Wikidata conflicts are dropped, not guessed. Page hooks and evidence come from the Wikipedia REST summary (CC BY-SA 4.0).
