Hideo Mōri

Hideo Mōri is a astronomy 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 Hideo Mōri rather than just read about it. In short: Hideo Mōri (毛利秀雄, Mōri Hideo), also spelt as Hideo Mohri, is a Japanese biologist. He is best known for the discovery of tubulin.

Key takeaways

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

Reference excerpt

Hideo Mōri (毛利秀雄, Mōri Hideo), also spelt as Hideo Mohri, is a Japanese biologist. He is best known for the discovery of tubulin.

Life He was born on 6 June 1930. He is the great-grandson of Duke Sadahiro Mōri, the 28th head of the Mōri clan. He is also related to the Tokugawa clan through his grandmother Masako, who was a sister of Marquess Yoshichika Tokugawa, the botanist. His maternal grandmother, Ariko, was the daughter of the founder of Shiseido, Arinobu Fukuhara, and through him, he is related to the Nobel laureate in Chemistry, Ryoji Noyori. He graduated from the University of Tokyo's Faculty of Science, Department of Zoology in 1953. His specialisation was in reproductive biology and animal physiological chemistry. He continued research on sperm at the graduate school of his alma mater and the university's Misaki Marine Biological Centre from 1968 to 1990. He elucidated the constituent proteins of the sperm flagellum's structural body (cytoskeleton). In 1968, he determined the amino acid composition of the microtubule's constituent proteins and named it tubulin. From 1987 to 1989, he served as Dean of the College of Arts and Sciences. In 1991, he retired from the University of Tokyo and was conferred the title of professor emeritus.

Worked examples

Example 1 — a first encounter with Hideo Mōri

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

In research: Hideo Mōri appears in astronomy 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 Hideo Mōri 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: Hideo Mōri is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1930 births, Academic staff of the University of Tokyo, Japanese biologists, so understanding it makes those chapters shorter.
In everyday life: Look for Hideo Mōri 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.
