Junko Shigemitsu

Junko Shigemitsu is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Junko Shigemitsu rather than just read about it. In short: Junko Shigemitsu (born 1949) is a Japanese-American physicist known for her use of lattice gauge theory and lattice QCD to calculate predicted values for decay constants and other physical quantities. She is a professor emerita of physics at Ohio State University.

Key takeaways

Junko Shigemitsu belongs to physics; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Junko Shigemitsu to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Junko Shigemitsu from memory before moving on to harder problems.

Reference excerpt

Junko Shigemitsu (born 1949) is a Japanese-American physicist known for her use of lattice gauge theory and lattice QCD to calculate predicted values for decay constants and other physical quantities. She is a professor emerita of physics at Ohio State University.

Education and career Shigemitsu graduated from Sophia University in 1973, and completed her Ph.D. at Cornell University in 1978, under the supervision of John Kogut. After postdoctoral research at the Institute for Advanced Study and Brown University, she joined the Ohio State University faculty as an assistant professor in 1982. She was promoted to associate professor in 1987, and full professor in 1992.

Recognition In 2000, Shigemitsu was named a Fellow of the American Physical Society (APS), after a nomination from the APS Division of Particles and Fields, "for her contributions to determining properties of the Standard Model using the methods of Lattice Gauge Theory". Ohio State University named her a distinguished scholar in 2011, and in 2014 Fermilab named her a Ben Lee Fellow.

Worked examples

Example 1 — a first encounter with Junko Shigemitsu

Start with the simplest possible case. Write down what Junko Shigemitsu 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 Junko Shigemitsu 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 Junko Shigemitsu 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 Junko Shigemitsu

In research: Junko Shigemitsu 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 Junko Shigemitsu 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: Junko Shigemitsu is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1949 births, 21st-century American women, American physicists, so understanding it makes those chapters shorter.
In everyday life: Look for Junko Shigemitsu 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.
