Gu Chaohao

Gu Chaohao 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 Gu Chaohao rather than just read about it. In short: Gu Chaohao (Chinese: 谷超豪; pinyin: Gǔ Chāoháo; Wade–Giles: Ku Ch'aohao; May 15, 1926 – June 24, 2012) was a Chinese mathematician. He graduated from National Chekiang University (Zhejiang University) in 1948, and received a doctorate in physics and mathematical science from Moscow University in 1959.

Key takeaways

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

Reference excerpt

Gu Chaohao (Chinese: 谷超豪; pinyin: Gǔ Chāoháo; Wade–Giles: Ku Ch'aohao; May 15, 1926 – June 24, 2012) was a Chinese mathematician. He graduated from National Chekiang University (Zhejiang University) in 1948, and received a doctorate in physics and mathematical science from Moscow University in 1959. He was primarily engaged in research on partial differential equations, differential geometry, solitons, and mathematical physics. He served as vice president of Fudan University and from 1988 to 1993 as president of the University of Science and Technology of China. In 1980, he was elected an academician of the Chinese Academy of Sciences. He received the Highest Science and Technology Award in 2009.

Worked examples

Example 1 — a first encounter with Gu Chaohao

Start with the simplest possible case. Write down what Gu Chaohao 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 Gu Chaohao 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 Gu Chaohao 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 Gu Chaohao

In research: Gu Chaohao 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 Gu Chaohao 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: Gu Chaohao is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1926 births, 2012 deaths, Academic staff of Fudan University, so understanding it makes those chapters shorter.
In everyday life: Look for Gu Chaohao 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.

Frequently asked questions

What is Gu Chaohao in simple terms?

Why does Gu Chaohao 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 Gu Chaohao?

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.
