Tang Yuhan

Tang Yuhan 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 Tang Yuhan rather than just read about it. In short: Tang Yuhan, or Hans Tang (Chinese: 湯于翰; pinyin: Tāng Yúhàn; 1913 – 25 May 2014) was a Hong Kong-Chinese oncologist and businessman. He founded the Sino-Belgium Cancer Hospital of Radiation Therapy in Shanghai and served as president of the Hong Kong Chinese Medical Association (香港中華醫學會) and the founder of Tang Fund (湯氏基金).

Key takeaways

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

Reference excerpt

Tang Yuhan, or Hans Tang (Chinese: 湯于翰; pinyin: Tāng Yúhàn; 1913 – 25 May 2014) was a Hong Kong-Chinese oncologist and businessman. He founded the Sino-Belgium Cancer Hospital of Radiation Therapy in Shanghai and served as president of the Hong Kong Chinese Medical Association (香港中華醫學會) and the founder of Tang Fund (湯氏基金).

Life

Early life Tang was born in Zhenhai, Zhejiang, China. He entered elementary school in Ningbo, and spent part of his childhood in Shanghai. He obtained his first M.D. from Shanghai Medical College (now the medical school of Fudan University). He then went to Western Europe and continued his study in medicine, especially in cancer therapy. He obtained his second doctor's degree from the Catholic University of Leuven in Belgium. He subsequently returned to Shanghai and served as president of the Sino-Belgian Radium Institute, the first cancer specialty hospital in China, and president of the Chinese Red Cross General Hospital.

1950s Tang went to Hong Kong as a doctor and businessman. He cooperated with Henry Fok in a series of investments. During this period, he became the member of Royal College of Physicians of London and Royal College of Physicians of Edinburgh and was selected to be the president of Hong Kong Chinese Medical Association (香港中華醫學會).

1990s and later Tang visited Chinese mainland many times. As a member of Ningbo Group (寧波幫), he made contributions to Chinese education. A hospital affiliated to Ningbo University in Ningbo is named after him. He donated more than 10 million yuan RMB for this hospital, which was opened in 2005. To honor his donations, the Ningbo Government awarded him Honorary Citizenship of Ningbo in 1998 and the Zhejiang Government awarded him the honorary title of "Loving-Homeland Model" (愛鄉楷模) in 2000.

Personal life Tang's wife, Chen Yunshang, was an actress during the 1940s in Hong Kong and Shanghai. They married in 1943. Tang was a vegetarian and spoke several European languages.

Memberships and other roles Member, Royal College of Physicians of London Member, Royal College of Physicians of Edinburgh Member, Hong Kong College of Physicians Member, Hong Kong Academy of Medicine Member, FHKAM (Medicine) Member and former president of Hong Kong Chinese Association of Medicine Honorary director of the Medical School, Ningbo University

Notes

Worked examples

Example 1 — a first encounter with Tang Yuhan

Start with the simplest possible case. Write down what Tang Yuhan 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 Tang Yuhan 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 Tang Yuhan 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 Tang Yuhan

In research: Tang Yuhan 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 Tang Yuhan 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: Tang Yuhan is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1913 births, 2014 deaths, Businesspeople from Ningbo, so understanding it makes those chapters shorter.
In everyday life: Look for Tang Yuhan 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.
