Yamamoto Senji

Yamamoto Senji is a biology 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 Yamamoto Senji rather than just read about it. In short: Yamamoto Senji (山本宣治; 28 May 1889 – 5 March 1929) was a Japanese biologist and leftist politician during the interwar period of Showa era Japan. Political career Yamamoto was elected to the House of Representatives in the 1928 General Election in February, being one of the two members of the Labour-Farmer Party who got elected, alongside Mizutani Chozaburo.

Key takeaways

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

Reference excerpt

Yamamoto Senji (山本宣治; 28 May 1889 – 5 March 1929) was a Japanese biologist and leftist politician during the interwar period of Showa era Japan.

Political career Yamamoto was elected to the House of Representatives in the 1928 General Election in February, being one of the two members of the Labour-Farmer Party who got elected, alongside Mizutani Chozaburo. The party was subsequently banned less than a month after the election, but both representatives retained their parliamentary functions. During his term he criticized the torture and illegal detention of prisoners by the police and unsuccessfully spoke against amending the Peace Preservation Law of 1925 to include the death penalty. Despite this, the amendment was passed in the Diet by a vote of 249-170. On that night, he was killed by a right-wing assassin at an inn in the Kanda district of Tokyo.

Worked examples

Example 1 — a first encounter with Yamamoto Senji

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

In research: Yamamoto Senji appears in biology 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 Yamamoto Senji 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: Yamamoto Senji is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1889 births, 1929 deaths, Activists from Kyoto Prefecture, so understanding it makes those chapters shorter.
In everyday life: Look for Yamamoto Senji 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.
