This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Masakatsu Shibasaki rather than just read about it. In short: Masakatsu Shibasaki (柴崎正勝, Shibasaki Masakatsu; born 25 January 1947) is a Japanese chemist. In 1974 he earned his doctorate in chemistry, in the group of Shun’ichi Yamada.

Key takeaways

Masakatsu Shibasaki 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 Shibasaki to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Masakatsu Shibasaki from memory before moving on to harder problems.

Reference excerpt

Masakatsu Shibasaki (柴崎正勝, Shibasaki Masakatsu; born 25 January 1947) is a Japanese chemist. In 1974 he earned his doctorate in chemistry, in the group of Shun’ichi Yamada. He did a post doc with Elias J. Corey at Harvard. He returned to Japan and became a professor in 1977 at Teikyō University and moved to Hokkaidō University in 1986. 1983–1986 Shibasaki was a research group leader at the Sagami chemical research center. From 1991 until 2010 he served as professor at Tokyo University. Since 2010 he is representative director of Microbial Chemistry Research Foundation (Chemistry), Tokyo. He is perhaps best known for developing a range of binol based heterobimetallic catalysts, which now bear his name.

Worked examples

Example 1 — a first encounter with Masakatsu Shibasaki

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

In research: Masakatsu Shibasaki 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 Shibasaki 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 Shibasaki is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1947 births, Academic staff of Hokkaido University, Academic staff of Teikyo University, so understanding it makes those chapters shorter.
In everyday life: Look for Masakatsu Shibasaki 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.
