Wang Dacheng

Wang Dacheng 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 Wang Dacheng rather than just read about it. In short: Wang Dacheng (Chinese: 王大成; pinyin: Wáng Dàchéng; 11 June 1940 – 19 September 2025) was a Chinese molecular biophysicist, and an academician of the Chinese Academy of Sciences. He was renowned as one of the pioneers of protein crystallography and structural biology in China.

Key takeaways

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

Reference excerpt

Wang Dacheng (Chinese: 王大成; pinyin: Wáng Dàchéng; 11 June 1940 – 19 September 2025) was a Chinese molecular biophysicist, and an academician of the Chinese Academy of Sciences. He was renowned as one of the pioneers of protein crystallography and structural biology in China. He was vice chairman of the Chinese Biophysical Society and vice chairman of the Chinese Crystallographic Society.

Early life and education Wang was born on 11 June 1940 in Chengdu, Sichuan, and graduated from the University of Science and Technology of China (USTC) in 1963 with a degree in biophysics.

Career After university, Wang began his career at the Institute of Biophysics, Chinese Academy of Sciences (CAS) in 1963, where he served as deputy director of the Institute and director of the Molecular Biology Research Center. He was also a visiting scholar at the Max Planck Institute for Biochemistry in Germany as an Alexander von Humboldt Research Fellow (1982–1984). In 1988, he went to the Protein Crystallography Laboratory of the Department of Chemistry at the University of York in the United Kingdom to study and work as a Wellcome Research Fellow.

Death On 19 September 2025, Wang died in Beijing, at the age of 85.

Honours and awards 2005 Member of the Chinese Academy of Sciences (CAS)

Worked examples

Example 1 — a first encounter with Wang Dacheng

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

In research: Wang Dacheng 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 Wang Dacheng 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 Dacheng is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1940 births, 2025 deaths, 20th-century Chinese scientists, so understanding it makes those chapters shorter.
In everyday life: Look for Wang Dacheng 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.
