Masayuki Iwamoto

Masayuki Iwamoto 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 Masayuki Iwamoto rather than just read about it. In short: Masayuki Iwamoto (岩本雅之, Iwamoto Masayuki; born 1954) is a Japanese astronomer from Awa in the Tokushima Prefecture. The Minor Planet Center credits him with the co-discovery of 6 asteroids made together with Japanese astronomer Toshimasa Furuta at the Tokushima-Kainan Astronomical Observatory (872) in 1988 and 1989.

Key takeaways

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

Reference excerpt

Masayuki Iwamoto (岩本雅之, Iwamoto Masayuki; born 1954) is a Japanese astronomer from Awa in the Tokushima Prefecture. The Minor Planet Center credits him with the co-discovery of 6 asteroids made together with Japanese astronomer Toshimasa Furuta at the Tokushima-Kainan Astronomical Observatory (872) in 1988 and 1989. He also received the Edgar Wilson Award in 2013 for the discovery of comet C/2013 E2, in 2019 for the discovery of the comets C/2018 V1 and C/2018 Y1, and in 2020 for the discovery of C/2020 A2. The inner main-belt asteroid 4951 Iwamoto, discovered by astronomers Yoshikane Mizuno and Toshimasa Furuta, was named in his honor on 5 March 1996 (M.P.C. 26763).

Worked examples

Example 1 — a first encounter with Masayuki Iwamoto

Start with the simplest possible case. Write down what Masayuki Iwamoto 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 Masayuki Iwamoto 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 Masayuki Iwamoto 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 Masayuki Iwamoto

In research: Masayuki Iwamoto 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 Masayuki Iwamoto 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: Masayuki Iwamoto is common in secondary-school and first-year university syllabi. It links to neighbouring topics 20th-century Japanese astronomers, Discoverers of asteroids, Discoveries by Masayuki Iwamoto, so understanding it makes those chapters shorter.
In everyday life: Look for Masayuki Iwamoto 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.
