Seiji Ueda

Seiji Ueda 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 Seiji Ueda rather than just read about it. In short: Seiji Ueda (上田清二, Ueda Seiji; born 1952) is a Japanese astronomer. He is a prolific discoverer of minor planets.

Key takeaways

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

Reference excerpt

Seiji Ueda (上田清二, Ueda Seiji; born 1952) is a Japanese astronomer. He is a prolific discoverer of minor planets. Between 1987 and 2000, Ueda discovered 705 asteroids, all of them in collaboration with Hiroshi Kaneda. Ueda holds an MD and PhD from Stanford University and is on the staff at the Graduate University for Advanced Study in Japan. The inner main-belt asteroid 4676 Uedaseiji, discovered in 1990, is named for him.

Worked examples

Example 1 — a first encounter with Seiji Ueda

Start with the simplest possible case. Write down what Seiji Ueda 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 Seiji Ueda 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 Seiji Ueda 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 Seiji Ueda

In research: Seiji Ueda 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 Seiji Ueda 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: Seiji Ueda is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1952 births, 20th-century Japanese astronomers, Discoverers of asteroids, so understanding it makes those chapters shorter.
In everyday life: Look for Seiji Ueda 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.

Why does Seiji Ueda matter?

Because it connects several astronomy ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Seiji Ueda?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
