Kao Ying-jer

Kao Ying-jer 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 Kao Ying-jer rather than just read about it. In short: Kao Ying-jer (Chinese: 高英哲) is a Taiwanese physicist. Kao earned a PhD from the University of Chicago in 2001 and conducted postdoctoral research at the University of Waterloo and the University of Toronto before joining the faculty of National Taiwan University in 2005 as an assistant professor.

Key takeaways

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

Reference excerpt

Kao Ying-jer (Chinese: 高英哲) is a Taiwanese physicist. Kao earned a PhD from the University of Chicago in 2001 and conducted postdoctoral research at the University of Waterloo and the University of Toronto before joining the faculty of National Taiwan University in 2005 as an assistant professor. He was promoted to associate professor in 2009 and full professor in 2013. He previously served as chair of the Taiwan Physical Society. Kao was elected a fellow of the American Physical Society in 2025 “[f]or contributions to numerical methods to study emergent phenomena in quantum many-body systems, while tirelessly promoting experimental and theoretical sciences within Asia and developing stronger ties with the U.S.

Worked examples

Example 1 — a first encounter with Kao Ying-jer

Start with the simplest possible case. Write down what Kao Ying-jer 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 Kao Ying-jer 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 Kao Ying-jer 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 Kao Ying-jer

In research
Kao Ying-jer 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 Kao Ying-jer 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
Kao Ying-jer is common in secondary-school and first-year university syllabi. It links to neighbouring topics 21st-century Taiwanese physicists, Academic staff of the National Taiwan University, Fellows of the American Physical Society, so understanding it makes those chapters shorter.
In everyday life
Look for Kao Ying-jer 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.

Frequently asked questions

What is Kao Ying-jer in simple terms?

Kao Ying-jer (Chinese: 高英哲) is a Taiwanese physicist. Kao earned a PhD from the University of Chicago in 2001 and conducted postdoctoral research at the University of Waterloo and the University of Toronto before joining the faculty of National Taiwan University in 2005 as an assistant professor.

Why does Kao Ying-jer matter?

Because it connects several physics ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Kao Ying-jer?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
