Reference excerpt

Mogami Tokunai (最上徳内; c. 1755 – October 14, 1836) was a Japanese samurai, geographer and explorer. Mogami was born in Dewa Province in what is now part of Yamagata Prefecture). He explored and mapped Hokkaido and Sakhalin and some of the Kuril Islands in 1785–1786. In his reports to the Tokugawa shogunate, he emphasized the need to defend the islands. He compiled a preliminary Ainu-Japanese dictionary in Ezo Soshi.

Worked examples

Example 1 — a first encounter with Mogami Tokunai

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

In research: Mogami Tokunai appears in science 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 Mogami Tokunai 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: Mogami Tokunai is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1755 births, 1836 deaths, Deified Japanese men, so understanding it makes those chapters shorter.
In everyday life: Look for Mogami Tokunai 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.
