Kwan Hsu

Kwan Hsu 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 Kwan Hsu rather than just read about it. In short: Kwan Hsu (1913-1995) was a Biophysics Professor at Portland State University and cultural liaison for the People's Republic of China. Early life Kwan Hsu was born in 1913 in the Guang-Xi Province of China and grew up in Shanghai.

Key takeaways

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

Reference excerpt

Kwan Hsu (1913-1995) was a Biophysics Professor at Portland State University and cultural liaison for the People's Republic of China.

Early life Kwan Hsu was born in 1913 in the Guang-Xi Province of China and grew up in Shanghai. Hsu and her father traveled around Southeast Asia after her mother's death, which occurred when she was 4. Her father assisted a radical faction of Guomindang (the Guangxi Army). While in Japanese-occupied Shanghai, Hsu was the sole breadwinner for brothers and stepmother.

Education Hsu attended Catholic missionary grammar and high school. She studied at the University of Shanghai and graduated in 1936 with a Bachelor of Science degree, with honors in Physics. She scored the highest in a competition for the American Association of University Women’s scholarship, which allowed her to travel to the U.S. in 1947. She was one of the first foreign women to receive this award after World War II. After the U.S. government cut ties with the People's Republic of China, she couldn't return home. She had planned to study abroad for her advanced degree, but those plans were blocked by the outbreak of the Second Sino-Japanese War (1937–45). She studied at both the University of Minnesota and University of Iowa before enrolling in a program at UC Berkeley. In 1960, Hsu graduated from the University of California, Berkeley with a Ph.D. in Biophysics; she was 47. While at UC Berkeley, she did research at the Donner Lab and wrote her thesis on the radiation effect on the permeability of yeast cells to sodium and potassium ions; it was printed for U.S. Atomic Energy Commission in December 1959.

Portland State University She moved to Portland in 1964 and took a position as the first Biophysics Professor at Portland State College. She retired in 1978 but continued to research until 1985. Her main focus was on the creation of artificial lipid membranes, the properties of those membranes, and creating stable models that could be grown in a lab.

Community and Organizational Involvement When she arrived in Oregon, Hsu became the People's Republic of China cultural liaison to Portland and Oregon. She was a member of the Chinese Scientists and Engineers, the U.S.-China People's Friendship Association (USCPFA), and the Northwest China Council. She worked as a resource for students and researchers from China who were living in the Portland area. She was the community contact for 6 new college professors from Guangxi Teacher's College in Guilin as part of an exchange program with Lewis and Clark College; this was the first large-scale exchange program between Chinese and American colleges.

Death and legacy Hsu died in November 1995 in Portland, Oregon.

Worked examples

Example 1 — a first encounter with Kwan Hsu

Start with the simplest possible case. Write down what Kwan Hsu 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 Kwan Hsu 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 Kwan Hsu 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 Kwan Hsu

In research: Kwan Hsu 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 Kwan Hsu 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: Kwan Hsu is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1913 births, 1995 deaths, 20th-century women biologists, so understanding it makes those chapters shorter.
In everyday life: Look for Kwan Hsu 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 Kwan Hsu in simple terms?

Kwan Hsu (1913-1995) was a Biophysics Professor at Portland State University and cultural liaison for the People's Republic of China. Early life Kwan Hsu was born in 1913 in the Guang-Xi Province of China and grew up in Shanghai.

Why does Kwan Hsu 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 Kwan Hsu?

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.
