Hōei Nojiri

Hōei Nojiri 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 Hōei Nojiri rather than just read about it. In short: Hōei Nojiri (野尻 抱影, Nojiri Hōei; November 15, 1885 – October 30, 1977) was a Japanese essayist and astronomer. He was a brother of the novelist Nojiri Haruhikoˀ, whose pen name was Osaragi Jirō.

Key takeaways

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

Reference excerpt

Hōei Nojiri (野尻 抱影, Nojiri Hōei; November 15, 1885 – October 30, 1977) was a Japanese essayist and astronomer. He was a brother of the novelist Nojiri Haruhikoˀ, whose pen name was Osaragi Jirō. In 1930 he coined the Japanese word Meiōsei (冥王星, "Star of the King (God) of the Underworld") for the then-newly-discovered dwarf planet Pluto. The name was then borrowed into Chinese and Korean.

Worked examples

Example 1 — a first encounter with Hōei Nojiri

Start with the simplest possible case. Write down what Hōei Nojiri 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 Hōei Nojiri 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 Hōei Nojiri 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 Hōei Nojiri

In research
Hōei Nojiri 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 Hōei Nojiri 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
Hōei Nojiri is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1885 births, 1977 deaths, 20th-century Japanese astronomers, so understanding it makes those chapters shorter.
In everyday life
Look for Hōei Nojiri 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.
