Guo Guangcan

Guo Guangcan is a physics 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 Guo Guangcan rather than just read about it. In short: Guo Guangcan (simplified Chinese: 郭光灿; traditional Chinese: 郭光燦; Pe̍h-ōe-jī: Koeh Kong-chhàn; born 9 December 1942) is a Chinese physicist. He is a professor at the University of Science and Technology of China (USTC) and Peking University (PKU).

Key takeaways

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

Reference excerpt

Guo Guangcan (simplified Chinese: 郭光灿; traditional Chinese: 郭光燦; Pe̍h-ōe-jī: Koeh Kong-chhàn; born 9 December 1942) is a Chinese physicist. He is a professor at the University of Science and Technology of China (USTC) and Peking University (PKU). He works on quantum information, quantum communication and quantum optic. He is an academician of the Chinese Academy of Sciences and The World Academy of Sciences.

Biography Guo was born in Hui'an County, Quanzhou, Fujian province in 1942.

Worked examples

Example 1 — a first encounter with Guo Guangcan

Start with the simplest possible case. Write down what Guo Guangcan claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, 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 Guo Guangcan 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 Guo Guangcan 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 Guo Guangcan

In research: Guo Guangcan appears in physics 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 Guo Guangcan 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: Guo Guangcan is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1942 births, Academic staff of Peking University, Academic staff of the University of Science and Technology of China, so understanding it makes those chapters shorter.
In everyday life: Look for Guo Guangcan 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.
