Reference excerpt

Hiroshi Suura (born August 19, 1925, Hiroshima, Japan – September 15, 1998) was a Japanese theoretical physicist, specializing in particle physics.

Education and career Suura graduated in 1947 with a B.S. from the University of Tokyo and in 1954 with a Ph.D. in physics from Hiroshima University. From September 1955 to June 1956 he did research at the Institute for Advanced Study. From 1960 to 1965 he was a professor at Nihon University. From 1965 until his retirement as professor emeritus, he was a professor at the University of Minnesota. In the theory of infrared corrections, Suura made important contributions, essential for many precise measurements involving elementary particles, especially electrons.

... another theme running through Hiroshi’s work and connecting it to the major issues of today’s particle physics is the idea of “particles in loops.” One of his most-quoted results concerns the effect of electron loops in the calculation of the muon’s anomalous magnetic moment aμ ... This leads to a difference between aμ and the corresponding quantity ae for the electron, which was confirmed in beautiful experiments at CERN ... and is still the subject of intense scrutiny ... He was elected in 1967 a Fellow of the American Physical Society. On June 1, 1994, the University of Minnesota held a colloquium in honor of Hiroshi Suura. After his death, the Physical Society of Japan published a collection of articles as a memorial to him.

Worked examples

Example 1 — a first encounter with Hiroshi Suura

Start with the simplest possible case. Write down what Hiroshi Suura claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Hiroshi Suura before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Hiroshi Suura ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Hiroshi Suura

In research: Hiroshi Suura appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Hiroshi Suura in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Hiroshi Suura is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1925 births, 1998 deaths, 20th-century Japanese physicists, so understanding it makes those chapters shorter.
In everyday life: Look for Hiroshi Suura outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
