Long Yiming

Long Yiming is a science 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 Long Yiming rather than just read about it. In short: Long Yiming (born October 1948) is a Chinese mathematician, and professor at Nankai University. He is a fellow of the Chinese Academy of Sciences.

Key takeaways

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

Reference excerpt

Long Yiming (born October 1948) is a Chinese mathematician, and professor at Nankai University. He is a fellow of the Chinese Academy of Sciences. His research focuses on symplectic geometry, nonlinear functional analysis, celestial mechanics, the variation method, and the Hamiltonian system. He is a distinguished professor of the Changjiang Scholars Program and the Director-General of the Chinese Mathematical Society.

Education Between 1978 and 1981, he was a student at Nankai University, where he obtained a master's degree. Between August 1983 and December 1987, he was a student at the University of Wisconsin-Madison, where he received a doctorate degree in mathematics.

Worked examples

Example 1 — a first encounter with Long Yiming

Start with the simplest possible case. Write down what Long Yiming claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Long Yiming 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 Long Yiming 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 Long Yiming

In research: Long Yiming appears in science 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 Long Yiming 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: Long Yiming is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1948 births, Chinese scientists, Living people, so understanding it makes those chapters shorter.
In everyday life: Look for Long Yiming 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.
