Syoziro Asahina

Syoziro Asahina is a biology 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 Syoziro Asahina rather than just read about it. In short: Syoziro Asahina (朝比奈正二郎, Asahina Shōjirō; June 10, 1913, Bunkyō, Tokyo – November 28, 2010) was a Japanese entomologist, specializing in dragonflies and damselflies. Life Asahina's father, Yasuhiko Asahina, was a professor of pharmacology at Tokyo Imperial University.

Key takeaways

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

Reference excerpt

Syoziro Asahina (朝比奈正二郎, Asahina Shōjirō; June 10, 1913, Bunkyō, Tokyo – November 28, 2010) was a Japanese entomologist, specializing in dragonflies and damselflies.

Life Asahina's father, Yasuhiko Asahina, was a professor of pharmacology at Tokyo Imperial University. Asahina began studying Odonata as a senior school student, and took part in collecting trips to Hokkaido and southern Sakhalin with his father. He spent much of his career as Chief of the Department of Medical Entomology at the Japanese National Institute of Health, from which he retired in 1979. He was president of the Entomological Society of Japan from 1971–1972 and president of the Japanese Society of Systematic Zoology from 1982–1983. Asahina died in 2010 at the age of 97.

Worked examples

Example 1 — a first encounter with Syoziro Asahina

Start with the simplest possible case. Write down what Syoziro Asahina claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, 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 Syoziro Asahina 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 Syoziro Asahina 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 Syoziro Asahina

In research: Syoziro Asahina appears in biology 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 Syoziro Asahina 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: Syoziro Asahina is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1913 births, 2010 deaths, 20th-century Japanese biologists, so understanding it makes those chapters shorter.
In everyday life: Look for Syoziro Asahina 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.
