Sanshi Imai

Sanshi Imai 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 Sanshi Imai rather than just read about it. In short: Sanshi Imai (今井三子, Imai Sanshi; 1900–1976) was a Japanese mycologist of Hokkaido Imperial University. Eponymous taxa Clitocybe imaiana Imaia Lactarius imaianus Stropharia imaiana Selected publications Sanshi Imai (1929) "On the Clavariaceae of Japan: I".

Key takeaways

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

Worked examples

Example 1 — a first encounter with Sanshi Imai

Start with the simplest possible case. Write down what Sanshi Imai 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 Sanshi Imai 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 Sanshi Imai 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 Sanshi Imai

In research: Sanshi Imai 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 Sanshi Imai 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: Sanshi Imai is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1900 births, 1976 deaths, 20th-century Japanese botanists, so understanding it makes those chapters shorter.
In everyday life: Look for Sanshi Imai 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.
