Wang Pinxian

Wang Pinxian 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 Wang Pinxian rather than just read about it. In short: Wang Pinxian (Chinese: 汪品先; born 14 November 1936 in Suzhou, Jiangsu) is a Chinese marine geologist. He is an academician of the Chinese Academy of Sciences.

Key takeaways

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

Reference excerpt

Wang Pinxian (Chinese: 汪品先; born 14 November 1936 in Suzhou, Jiangsu) is a Chinese marine geologist. He is an academician of the Chinese Academy of Sciences.

Biography Wang obtained his degree in geology from Moscow State University of the Soviet Union in 1960, and taught at East China Normal University in Shanghai afterwards. In 1972, when the Marine Geology department of East China Normal University merged into Tongji University, Wang was transferred to Tongji. He was elected a member of the Chinese Academy of Sciences (CAS) in 1991. He was vice president of the International Scientific Committee for Ocean Research (SCOR), 1994–1998. He has served as vice chairman of the Division of Earth Sciences of CAS, president of the Chinese Committee on Ocean Research and vice president of Oceanological and Limnological Society of China. He has been engaged in research on marine micropaleontology and evolution of its environmental pattern for decades and has made creative contributions to the development of marine geology in China. He started the research on the burial of microfossils in China and has developed the research on paleoceanography considerably. He was awarded a number of prizes including the National Natural Science Prize and the Ho Leung Ho Lee Prize. His research entitled Distribution of Calcareous Microfossils in the China Seas and its Paleenvironmental Significance won the first prize for the Advancement of Science and Technology awarded by the former State Education Commission and the fourth place for the National Natural Science Award. His research on Dynamic Progression and Development Trend of the Evolution of Environment in the last 150,000 years in Drought and Semi-drought Areas won the first prize for the Advancement of Science and Technology awarded by Chinese Academy of Science in 1998. In 2007, he was awarded the Milutin Milankovic Medal by the European Geosciences Union.

Worked examples

Example 1 — a first encounter with Wang Pinxian

Start with the simplest possible case. Write down what Wang Pinxian 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 Wang Pinxian 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 Wang Pinxian 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 Wang Pinxian

In research: Wang Pinxian 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 Wang Pinxian 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: Wang Pinxian is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1936 births, 20th-century Chinese geologists, Academic staff of Tongji University, so understanding it makes those chapters shorter.
In everyday life: Look for Wang Pinxian 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.
