Kiichirō Furukawa

Kiichirō Furukawa 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 Kiichirō Furukawa rather than just read about it. In short: Kiichirō Furukawa (Japanese: 古川麒一郎, Hepburn: Furukawa Kiichirō; Kunrei: Hurukawa Kiitirô, 22 July 1929 – 29 June 2016) was a Japanese astronomer and discoverer of minor planets at the Tokyo Astronomical Observatory. Furukawa was also associated with Nagoya University Department of Astrophysics.

Key takeaways

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

Reference excerpt

Kiichirō Furukawa (Japanese: 古川麒一郎, Hepburn: Furukawa Kiichirō; Kunrei: Hurukawa Kiitirô, 22 July 1929 – 29 June 2016) was a Japanese astronomer and discoverer of minor planets at the Tokyo Astronomical Observatory. Furukawa was also associated with Nagoya University Department of Astrophysics.

Awards and honors Asteroid 3425 Hurukawa, a member of the Eos family and discovered by Karl Reinmuth at Heidelberg in 1929, was named in his honor. The official naming citation was published by the Minor Planet Center (MPC) on 16 December 1986 (M.P.C. 11443).

Discoveries Kiichirō Furukawa was a prolific discoverer of asteroids, credited by the MPC under the name K. Hurukawa with a total of 92 co-discovered numbered minor planets, all of them in collaboration with astronomer Hiroki Kosai.

Worked examples

Example 1 — a first encounter with Kiichirō Furukawa

Start with the simplest possible case. Write down what Kiichirō Furukawa 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 Kiichirō Furukawa 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 Kiichirō Furukawa 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 Kiichirō Furukawa

In research: Kiichirō Furukawa 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 Kiichirō Furukawa 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: Kiichirō Furukawa is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1929 births, 2016 deaths, 20th-century Japanese astronomers, so understanding it makes those chapters shorter.
In everyday life: Look for Kiichirō Furukawa 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.
