Poon Chung-kwong

Poon Chung-kwong 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 Poon Chung-kwong rather than just read about it. In short: Professor Poon Chung-kwong, GBS, OBE, JP (Chinese: 潘宗光, born 1940, Hong Kong) was the President of the Hong Kong Polytechnic University from 1991 to 2008. He received his secondary education at St.

Key takeaways

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

Reference excerpt

Professor Poon Chung-kwong, GBS, OBE, JP (Chinese: 潘宗光, born 1940, Hong Kong) was the President of the Hong Kong Polytechnic University from 1991 to 2008. He received his secondary education at St. Paul's Co-educational College. Trained as a chemist, he holds doctorates of science and of philosophy from the University College London. He has been a visiting scholar at University of Southern California and at California Institute of Technology. In addition to being the chief administrator of Hong Kong's largest scientific/technical university he is also a member of the National Committee of the Chinese People's Political Consultative Conference. His late cousin was the singer Leslie Cheung.

Worked examples

Example 1 — a first encounter with Poon Chung-kwong

Start with the simplest possible case. Write down what Poon Chung-kwong 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 Poon Chung-kwong 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 Poon Chung-kwong 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 Poon Chung-kwong

In research: Poon Chung-kwong 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 Poon Chung-kwong 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: Poon Chung-kwong is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1940 births, Academic staff of Hong Kong Polytechnic University, Alumni of St. John's College, University of Hong Kong, so understanding it makes those chapters shorter.
In everyday life: Look for Poon Chung-kwong 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.
