Ma Jin (geologist)

Ma Jin (geologist) 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 Ma Jin (geologist) rather than just read about it. In short: Ma Jin (Chinese: 马瑾; 27 November 1934 – 12 August 2018) was a Chinese geophysicist and structural geologist. She was a senior research fellow at the Institute of Geology of the China Earthquake Administration, and an academician of the Chinese Academy of Sciences.

Key takeaways

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

Reference excerpt

Ma Jin (Chinese: 马瑾; 27 November 1934 – 12 August 2018) was a Chinese geophysicist and structural geologist. She was a senior research fellow at the Institute of Geology of the China Earthquake Administration, and an academician of the Chinese Academy of Sciences.

Biography Ma was born on 27 November 1934 in Rugao, Jiangsu, Republic of China. She studied at the Beijing Institute of Geology from 1952 to 1956. After graduation, she entered the Institute of Geology of the Chinese Academy of Sciences (CAS) to study structural geology under Zhang Wenyou (张文佑). In 1958, she went to the Soviet Union to study at the Institute of Tectonophysics, USSR Academy of Sciences, and earned an associate doctor degree (Ph.D. equivalent) in 1962. After returning to China in 1962, she worked as an assistant researcher at the Institute of Geology of CAS. In 1978, she was transferred to the Institute of Geology of the China Earthquake Administration and promoted to associate research fellow. She became senior research fellow in 1981, and later served as Director of the institute's academic committee. She was a visiting scholar at the United States Geological Survey in 1983. Ma made significant contributions in tectonophysics, specifically the mechanisms of tectonic deformation and its relations to seismic activity. She published over 200 scientific papers and several monographs, and won more than 10 national and ministerial awards. She was elected an academician of the Chinese Academy of Sciences in 1997. Ma died in Beijing on 12 August 2018, at the age of 83.

Worked examples

Example 1 — a first encounter with Ma Jin (geologist)

Start with the simplest possible case. Write down what Ma Jin (geologist) 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 Ma Jin (geologist) 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 Ma Jin (geologist) 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 Ma Jin (geologist)

In research: Ma Jin (geologist) 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 Ma Jin (geologist) 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: Ma Jin (geologist) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1934 births, 2018 deaths, China University of Geosciences alumni, so understanding it makes those chapters shorter.
In everyday life: Look for Ma Jin (geologist) 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.
