Hideaki Ohba

Hideaki Ohba 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 Hideaki Ohba rather than just read about it. In short: Hideaki Ohba (or Ōba) (Japanese: 大場秀章) (born 1943) is a Japanese botanist, pteridologist, and taxonomist. He is a professor emeritus at the University of Tokyo.

Key takeaways

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

Worked examples

Example 1 — a first encounter with Hideaki Ohba

Start with the simplest possible case. Write down what Hideaki Ohba 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 Hideaki Ohba 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 Hideaki Ohba 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 Hideaki Ohba

In research: Hideaki Ohba 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 Hideaki Ohba 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: Hideaki Ohba is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1943 births, 20th-century Japanese botanists, 21st-century Japanese botanists, so understanding it makes those chapters shorter.
In everyday life: Look for Hideaki Ohba 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.
