Lim Kok Ann

Lim Kok Ann is a biology 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 Lim Kok Ann rather than just read about it. In short: Lim Kok Ann (simplified Chinese: 林国安; traditional Chinese: 林國安; pinyin: Lín Guó'ān) (27 January 1920 – 8 March 2003) was a Singaporean chess player and organizer, and a microbiologist specializing in enterovirus research. Early life Born 27 January 1920, Lim had been a student at Anglo-Chinese School and Raffles Institution in 1936 and in 1938 was a Queen's scholar.

Key takeaways

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

Reference excerpt

Lim Kok Ann (simplified Chinese: 林国安; traditional Chinese: 林國安; pinyin: Lín Guó'ān) (27 January 1920 – 8 March 2003) was a Singaporean chess player and organizer, and a microbiologist specializing in enterovirus research.

Early life Born 27 January 1920, Lim had been a student at Anglo-Chinese School and Raffles Institution in 1936 and in 1938 was a Queen's scholar.

Career

Microbiology As a microbiologist at the University of Malaya, Lim was the first to isolate the specific virus (Influenza A/Singapore/1/57) during the 1957–1958 influenza pandemic using chicken embryos in eggs. In 1959, while working for the World Health Organization in Houston, Texas, he developed the Lim-Benyesh-Melnick (LBM) protocol for serotyping human enterovirus isolates. By introducing various combinations of viruses in each egg (instead of testing for each one individually), scientists can more quickly isolate the specific virus using fewer trials, a procedure still in use decades later. In August 1965, Lim was appointed as the dean of the medical faculty at the University of Singapore, and in the 1960s he promoted acceptance of the novel Sabin polio vaccine amidst public skepticism of the new treatment.

Chess FIDE, the world chess federation, called Lim one of "the Fathers of Asian chess" for his work in promoting the game. The Straits Times called him "the father of chess" in Singapore. Lim founded the Singapore Chess Federation in 1949 which held its first national chess championship the same year. Lim won the event himself, and again in 1960 and 1968, and served as president of the federation for 18 years. From 1982 to 1988, Lim was the secretary general of FIDE, creating and publishing the first FIDE handbook. He is remembered for modernizing the fifty move rule in the computer age and creating the "Lim System" for tournament pairings.

Arts Lim co-founded Singapore's first multi-disciplinary arts centre, Centre 65, with Goh Poh Seng in 1965 to promote the arts.

Personal life Lim was the grandson of Lim Boon Keng, a doctor, educator, and philanthropist. Lim was married to Rosie Seow Guat Kheng (1922–1994), the daughter of Seow Poh Leng, a bank manager. She was an actress and a teacher. Lim was a Methodist, and had five children, among them the writer and playwright Stella Kon. He died of a heart attack on 8 March 2003.

Worked examples

Example 1 — a first encounter with Lim Kok Ann

Start with the simplest possible case. Write down what Lim Kok Ann claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, 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 Lim Kok Ann 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 Lim Kok Ann 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 Lim Kok Ann

In research: Lim Kok Ann appears in biology 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 Lim Kok Ann 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: Lim Kok Ann is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1920 births, 2003 deaths, 20th-century Singaporean sportsmen, so understanding it makes those chapters shorter.
In everyday life: Look for Lim Kok Ann 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.
