Zhang Zong

Zhang Zong 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 Zhang Zong rather than just read about it. In short: Zhang Zong (Chinese: 章综; 16 May 1929 – 27 August 2019) was a Chinese crystallographer and an academician of the Chinese Academy of Sciences (CAS). Biography Zhang was born in Yixing, Jiangsu, on May 16, 1929.

Key takeaways

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

Reference excerpt

Zhang Zong (Chinese: 章综; 16 May 1929 – 27 August 2019) was a Chinese crystallographer and an academician of the Chinese Academy of Sciences (CAS).

Biography Zhang was born in Yixing, Jiangsu, on May 16, 1929. After graduating from Nankai High School in Chongqing in July 1948, he was admitted to National Central University. After graduation, he was assigned to the Institute of Physics, Chinese Academy of Sciences (CAS). He joined the Chinese Communist Party the same year. In 1959 he went to the Semiconductor Institute of the Soviet Academy of Sciences to further his studies. He returned to China 1962. In 1978, Zhang was appointed deputy director of the CAS Institute of Physics. In November 1980 he was elected an academician of the Chinese Academy of Sciences (CAS). In 1982, he was appointed deputy director of the Division of Mathematics and Physics of the CAS, and was promoted to Director two years later. Zhang died on August 27, 2019, in Beijing, aged 90.

Worked examples

Example 1 — a first encounter with Zhang Zong

Start with the simplest possible case. Write down what Zhang Zong 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 Zhang Zong 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 Zhang Zong 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 Zhang Zong

In research: Zhang Zong 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 Zhang Zong 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: Zhang Zong is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1929 births, 2019 deaths, Crystallographers, so understanding it makes those chapters shorter.
In everyday life: Look for Zhang Zong 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.
