Hai-Lung Dai

Hai-Lung Dai 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 Hai-Lung Dai rather than just read about it. In short: Hai-Lung Dai (Chinese: 戴海龙) is a Taiwanese physical chemist and academic. He is the Laura H.

Key takeaways

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

Reference excerpt

Hai-Lung Dai (Chinese: 戴海龙) is a Taiwanese physical chemist and academic. He is the Laura H. Carnell Professor of Chemistry at Temple University in Philadelphia, Pennsylvania.

Early life and education Dai was born in Taiwan to waishengren parents who fled mainland China during the Great Retreat. His mother was an elementary school teacher. He was raised in Zhonghe District in New Taipei and graduated from Taipei Municipal Chien Kuo High School. After high school, Dai studied geology and chemistry at National Taiwan University and graduated with a Bachelor of Science (B.S.) in chemistry in 1974. Following military service, he went to the United States in 1976 for graduate studies. He obtained his doctorate in chemistry from the University of California at Berkeley in 1981.

Academic career After receiving his doctorate, Dai was a postdoctoral researcher at the Massachusetts Institute of Technology until 1984. That year he began teaching in the chemistry department of the University of Pennsylvania in Philadelphia, where he remained for twenty-two years and became department chair and the Hirschmann-Makineni Professor. He founded the Penn Science Teacher Institute that eventually trained 300 in-service science teachers and was named as a model for training science teachers in a 2005 National Academy of Sciences white paper. In 2007 he became Dean of the College of Science and Technology of Temple University, also in Philadelphia, Pennsylvania, and was Provost of Temple University during 2012 - 2016. During his time as provost, Temple's USNWR ranking went from #135 to #115 and Temple became a Carnegie R1 Highest Research Activity University. In 2017, Dai was appointed vice president for International Affairs at Temple University.

Worked examples

Example 1 — a first encounter with Hai-Lung Dai

Start with the simplest possible case. Write down what Hai-Lung Dai 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 Hai-Lung Dai 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 Hai-Lung Dai 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 Hai-Lung Dai

In research: Hai-Lung Dai 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 Hai-Lung Dai 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: Hai-Lung Dai is common in secondary-school and first-year university syllabi. It links to neighbouring topics Fellows of the American Chemical Society, Fellows of the American Physical Society, Humboldt Research Award recipients, so understanding it makes those chapters shorter.
In everyday life: Look for Hai-Lung Dai 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.
