Shih-Ying Lee

Shih-Ying Lee is a engineering 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 Shih-Ying Lee rather than just read about it. In short: Shih-Ying Lee or S. Y.

Key takeaways

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

Reference excerpt

Shih-Ying Lee or S. Y. Lee (Chinese: 李詩穎; pinyin: Lǐ Shīyǐng; April 30, 1918 – July 2, 2018) was an American aerodynamicist, businessman, inventor, and mechanical engineer who carried out research and innovation in hydrodynamics-related technologies. He was a professor emeritus at the Massachusetts Institute of Technology.

Biography Lee was born in 1918 in Beijing, Republic of China into a family of Fuzhou origin. Lee attended Tsinghua University in 1936, and obtained his bachelor's degree in civil engineering in 1940. Upon graduating, Lee worked as a bridge designer and hydraulic power research engineer for the Chinese government for nearly two years, then went to study in the United States in 1942. Lee obtained his Master and PhD in civil engineering at the Massachusetts Institute of Technology in 1943 and 1945. After graduation, Lee worked for two years at Cram and Ferguson Architects, before returning to MIT as a research engineer. He joined MIT's faculty in 1952 and retired from there in 1974. In 1985, Lee was elected a member of the United States National Academy of Engineering for his original research on control valve stability, for innovative dynamic measurement instrumentation, and for successful entrepreneurial commercialization of his inventions. Lee was granted many US patents. Lee founded or co-founded several companies specialized in process control and hydrodynamic instruments. Lee co-founded Dynisco Inc. and Setra Systems Inc. with his brother Y. T. Li, and was chairman of the company. He donated funds to establish the Shih-Ying Lee Scholarship at Tsinghua. He died in July 2018 at the age of 100.

Worked examples

Example 1 — a first encounter with Shih-Ying Lee

Start with the simplest possible case. Write down what Shih-Ying Lee claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, 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 Shih-Ying Lee 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 Shih-Ying Lee 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 Shih-Ying Lee

In research: Shih-Ying Lee appears in engineering 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 Shih-Ying Lee 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: Shih-Ying Lee is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1918 births, 2018 deaths, 20th-century American businesspeople, so understanding it makes those chapters shorter.
In everyday life: Look for Shih-Ying Lee 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.
