Masakatsu Aoki

Masakatsu Aoki 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 Masakatsu Aoki rather than just read about it. In short: Masakatsu Aoki (青木昌勝, Aoki Masakatsu; born 1957, Toyama Prefecture) is a Japanese amateur astronomer who operates from his private Aoki Astronomical Observatory (908) at Toyama, Toyama Prefecture, Japan. His main interest lies in supernovae of which he has discovered a total of 13, such a SN 1999eu as well as SN 2000db and SN 2000di.

Key takeaways

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

Reference excerpt

Masakatsu Aoki (青木昌勝, Aoki Masakatsu; born 1957, Toyama Prefecture) is a Japanese amateur astronomer who operates from his private Aoki Astronomical Observatory (908) at Toyama, Toyama Prefecture, Japan. His main interest lies in supernovae of which he has discovered a total of 13, such a SN 1999eu as well as SN 2000db and SN 2000di. In 2016, he discovered the supernova SN 2016C in NGC 5247. In the course of his search, he has also discovered two asteroids during 1996–1997. He has named the asteroid 58627 Rieko in honour of his wife.

Worked examples

Example 1 — a first encounter with Masakatsu Aoki

Start with the simplest possible case. Write down what Masakatsu Aoki 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 Masakatsu Aoki 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 Masakatsu Aoki 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 Masakatsu Aoki

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