Masahiko Yamada

Masahiko Yamada is a science 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 Masahiko Yamada rather than just read about it. In short: Masahiko Yamada (山田正彦, Yamada Masahiko; born 8 April 1942) is a Japanese politician who served as a member of the House of Representatives in the Diet (national legislature) between 1993 and 1996, and between 2003 and 2012. A native of Fukue, Nagasaki, a Roman Catholic, and graduate of Waseda University, he was elected to the House of Representatives for the first time in 1993 after unsuccessful runs in 1979, 1986…

Key takeaways

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

Reference excerpt

Masahiko Yamada (山田正彦, Yamada Masahiko; born 8 April 1942) is a Japanese politician who served as a member of the House of Representatives in the Diet (national legislature) between 1993 and 1996, and between 2003 and 2012. A native of Fukue, Nagasaki, a Roman Catholic, and graduate of Waseda University, he was elected to the House of Representatives for the first time in 1993 after unsuccessful runs in 1979, 1986 and 1990.

Worked examples

Example 1 — a first encounter with Masahiko Yamada

Start with the simplest possible case. Write down what Masahiko Yamada 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 Masahiko Yamada 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 Masahiko Yamada 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 Masahiko Yamada

In research: Masahiko Yamada 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 Masahiko Yamada 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: Masahiko Yamada is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1942 births, 20th-century Japanese lawyers, Democratic Party of Japan politicians, so understanding it makes those chapters shorter.
In everyday life: Look for Masahiko Yamada 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.
