Wang Xuan (computer scientist)

Wang Xuan (computer scientist) is a computer science 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 Wang Xuan (computer scientist) rather than just read about it. In short: Wang Xuan (simplified Chinese: 王选; traditional Chinese: 王選; pinyin: Wáng Xuǎn; February 5, 1937 – February 13, 2006) was a Chinese computer scientist. He was a computer application specialist and innovator of the Chinese printing industry, as well as an academician at both the Chinese Academy of Sciences and the Chinese Academy of Engineering.

Key takeaways

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

Reference excerpt

Wang Xuan (simplified Chinese: 王选; traditional Chinese: 王選; pinyin: Wáng Xuǎn; February 5, 1937 – February 13, 2006) was a Chinese computer scientist. He was a computer application specialist and innovator of the Chinese printing industry, as well as an academician at both the Chinese Academy of Sciences and the Chinese Academy of Engineering. He was the vice-president of the CPPCC and founder of the major technology conglomerate company Founder Group in 1986.

Biography

Wang was born into a distinguished intellectual family on 5 February 1937, in Shanghai, with his ancestral home in Wuxi, Jiangsu, to Wang Shouqi, a graduate of National Jiaotong University (now Shanghai Jiao Tong University), and Zhou Miaoqing. His grandfather Wang Zai was a politician during the late Qing dynasty (1644–1911). He had four siblings, with two brothers and two sisters. His eldest sister, Wang Jian, was admitted to the pre-medical program of Yenching University in 1947 and later studied at Peking Union Medical College and worked at the General Hospital of Nanjing Military Region after graduation. His eldest brother, Wang Yu, graduated from the Department of Electrical Engineering of National Jiaotong University and later taught at Datong Coal Mining School and the Beijing Coal Mining Cadre Management College. His second elder sister, Wang Jun, enrolled at the Department of Physics at Fudan University and was engaged in work related to nuclear physics. His second elder, Wang Xun, was an academician of the Chinese Academy of Sciences. Wang Xuan graduated from the Department of Mathematics and Mechanics at Peking University in 1958 and devoted himself to computer science education and research. He was mainly involved in research into computer processing of words, graphics and images. In 1975, he was in charge of the research and development of laser typesetting systems in the Chinese language and of electronic publishing systems. Surpassing Japan's second-generation optical designation and the third-generation CRT designation, the fourth-generation laser typesetting system he invented has not yet come onto the market in other countries. Thus he is dubbed "the Father of Chinese Language Laser Typesetting".

Awards and honors Wang Xuan was awarded the State Preeminent Science and Technology Award in 2001 by President Jiang Zemin. Started in 2000, this highest degree prize of science and technology in China, has only been awarded to 9 scientists by 2006. Asteroid 4913 Wangxuan, discovered at the Purple Mountain Observatory in 1965, was named in his memory. The official naming citation was published by the Minor Planet Center on 24 November 2007 (M.P.C. 61266).

Worked examples

Example 1 — a first encounter with Wang Xuan (computer scientist)

Start with the simplest possible case. Write down what Wang Xuan (computer scientist) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, 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 Wang Xuan (computer scientist) 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 Wang Xuan (computer scientist) 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 Wang Xuan (computer scientist)

In research: Wang Xuan (computer scientist) appears in computer science 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 Wang Xuan (computer scientist) 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: Wang Xuan (computer scientist) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1937 births, 2006 deaths, 20th-century Chinese inventors, so understanding it makes those chapters shorter.
In everyday life: Look for Wang Xuan (computer scientist) 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.
