Hui-lin Li is a astronomy 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 Hui-lin Li rather than just read about it. In short: Hui-lin Li (李惠林, 1911–2002) was a Chinese botanist, academic, and researcher who worked at the University of Pennsylvania, National Taiwan University, and Chinese Academy of Sciences. Biography Hui-lin Li was born in Soochow, a city close to Shanghai.

Key takeaways

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

Reference excerpt

Hui-lin Li (李惠林, 1911–2002) was a Chinese botanist, academic, and researcher who worked at the University of Pennsylvania, National Taiwan University, and Chinese Academy of Sciences.

Biography Hui-lin Li was born in Soochow, a city close to Shanghai. Li earned Biology degrees from Soochow University (B.S., 1930) and Yenching University (M.S., 1932). In 1940, he traveled to the United States, and earned a Ph.D. in Biology from Harvard University in 1942. From 1943 to 1946 Li studied under Francis W. Pennell and Jacob R. Schramm at the Academy of Natural Sciences of Philadelphia. Li was appointed to a professorship at Soochow University in 1946 and at National Taiwan University in Taipei in 1947. He returned to the United States and carried out research at the University of Virginia in 1950, the Smithsonian Institution in 1951, and the Morris Arboretum of the University of Pennsylvania in 1952. In 1958 Li joined the faculty at the University of Pennsylvania, where he remained until retiring in 1979. The collected Hui-lin Li Papers are archived at the University of Pennsylvania.

Selected publications From 1932 to 1983, Hui-lin Li published over 200 papers and 9 books. Some notable books are:

(1952) Floristic Relationships Between Eastern Asia and Eastern North America (1959) The Garden Flowers of China (1963) The Origin and Cultivation of Shade and Ornamental Trees (1972) Trees of Pennsylvania: the Atlantic States and the Lake States (1982) Contributions to Botany: Studies in Plant Geography, Phylogeny and Evolution, Ethnobotany and Dendrological and Horticultural Botany (2002) Chinese Flower Arrangement. Li was chair of the editorial committee and a contributor to the (1975-1979) Flora of Taiwan, and the first translator of the c. 304 Nanfang Caomu Zhuang "Plants of the Southern Regions" (1979).

Awards and honors Li was awarded a Harrison Fellowship for Research at the University of Pennsylvania in 1943, a Guggenheim Fellowship in 1961, and a Fulbright Fellowship in 1968. He won research grants from institutions such as the American Philosophical Society and American Council of Learned Societies. Li was elected a member of the Academia Sinica, Taiwan in 1964, and was a visiting Professor of Biology at the Chinese University of Hong Kong from 1964 to 1965.

Worked examples

Example 1 — a first encounter with Hui-lin Li

Start with the simplest possible case. Write down what Hui-lin Li 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 Hui-lin Li 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 Hui-lin Li 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 Hui-lin Li

In research: Hui-lin Li 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 Hui-lin Li 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: Hui-lin Li is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1911 births, 2002 deaths, 20th-century Chinese botanists, so understanding it makes those chapters shorter.
In everyday life: Look for Hui-lin Li 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.
