Paul Chien

Paul Chien is a chemistry 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 Paul Chien rather than just read about it. In short: Paul Kwan Chien (Chinese: 钱锟; pinyin: Qián Kūn; Jyutping: Cin4 Kwan1, born 1 January 1947) is a Hong Kong-American biologist known for his research on the physiology and ecology of intertidal organisms and his support for intelligent design.

Key takeaways

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

Reference excerpt

Paul Kwan Chien (Chinese: 钱锟; pinyin: Qián Kūn; Jyutping: Cin4 Kwan1, born 1 January 1947) is a Hong Kong-American biologist known for his research on the physiology and ecology of intertidal organisms and his support for intelligent design.

Biography Chien was born on 1 January 1947 in Hong Kong and earned bachelor's degrees in Biology and Chemistry from Chung Chi College of the Chinese University of Hong Kong in 1966 and his Ph.D. in 1971 from the University of California at Irvine in the laboratory of marine invertebrate physiologist Grover C. Stephens. After a brief postdoctoral fellowship in the laboratory of Wheeler J. North at the Kerckhoff marine laboratory of the California Institute of Technology in Corona del Mar, California, he joined the faculty of the University of San Francisco in 1973. His research has involved the transport of amino acids and metal ions across cell membranes as well as the detoxification mechanisms of metal ions.

Intelligent design Chien is a fellow of the Discovery Institute's Center for Science and Culture, hub of the intelligent design movement. Chien is described in the Discovery Institute's Wedge document as leading its "Paleontology Research program", in spite of the fact that, by his own admission, he has no credentials in the field. He has translated several books by intelligent design authors, such as Phillip Johnson's book Darwin on Trial and Jonathan Wells' Icons of Evolution, into Chinese.

Worked examples

Example 1 — a first encounter with Paul Chien

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

In research: Paul Chien appears in chemistry 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 Paul Chien 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: Paul Chien is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1947 births, 21st-century American biologists, 21st-century American chemists, so understanding it makes those chapters shorter.
In everyday life: Look for Paul Chien 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.
