This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Zhao Zhongxian rather than just read about it. In short: Zhao Zhongxian (simplified Chinese: 赵忠贤; traditional Chinese: 趙忠賢; pinyin: Zhào Zhōngxián; born 30 January 1941) is a Chinese physicist. He is internationally known for his studies on High-temperature superconductivity (HTS).

Key takeaways

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

Reference excerpt

Zhao Zhongxian (simplified Chinese: 赵忠贤; traditional Chinese: 趙忠賢; pinyin: Zhào Zhōngxián; born 30 January 1941) is a Chinese physicist. He is internationally known for his studies on High-temperature superconductivity (HTS). He was a member of the 8th, 10th, 11th National Committee of the Chinese People's Political Consultative Conference. He was also an alternate member of the 15th Central Committee of the Chinese Communist Party.

Biography Zhao was born in Xinmin, Liaoning, Manchukuo, on January 30, 1941. In 1959, he was accepted to the University of Science and Technology of China and graduated in 1964. After university, he was assigned to the Institute of Physics, Chinese Academy of Sciences as a researcher. In December 1973, he joined the Chinese Communist Party. That same year, he was sent abroad to study at the expense of the government. He was educated in the University of Cambridge from February 1974 to September 1975. In 1979, he became deputy director of Superconductor Classification Laboratory at the Institute of Physics, Chinese Academy of Sciences. In 1987 he was elected a fellow of the World Academy of Sciences (TWAS), and two years later he was elected a fellow of the World Ceramic Academy. In 1988, Chinese University of Hong Kong conferred on him an Honorary Doctor of Science. In 1991 he became a member of the Chinese Academy of Sciences. He was director of Division of Mathematics and Physics, Chinese Academy of Sciences from 1994 to 2000.

Worked examples

Example 1 — a first encounter with Zhao Zhongxian

Start with the simplest possible case. Write down what Zhao Zhongxian 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 Zhao Zhongxian 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 Zhao Zhongxian 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 Zhao Zhongxian

In research: Zhao Zhongxian 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 Zhao Zhongxian 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: Zhao Zhongxian is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1941 births, Alumni of the University of Cambridge, Fellows of The World Academy of Sciences, so understanding it makes those chapters shorter.
In everyday life: Look for Zhao Zhongxian 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.
