From Wikipedia, the free encyclopedia
In this Chinese name, the family name is Lam.

Lam Lay Yong (maiden name Oon Lay Yong, Chinese: 蓝丽蓉; pinyin: Lán Lìróng; born 1936) is a retired Professor of Mathematics.

Academic career[edit]

From 1988 to 1996 she was Professor at the Department of Mathematics, National University of Singapore (NUS). She graduated from the University of Malaya (later becoming University of Singapore) in 1957 and pursued graduate study in Cambridge University, obtaining her Ph.D. degree from University of Singapore in 1966, and becoming a lecturer at the University of Singapore. She was promoted to full professor in 1988, taught in NUS for 35 years, and retired in 1996.

From 1974 to 1990, Lam Lay Yong was the associate editor of Historia Mathematica. Lam was a member of Académie Internationale d'Histoire des Sciences.

In 2001, Lam Lay Yong was awarded the Kenneth O. May Prize jointly with Ubiratan D'Ambrosio.[1][2] Lam was the first Asian and first woman to receive this award.[3] Her reception speech was Ancient Chinese Mathematics and its influence on World Mathematics.

Lam Lay Yong also won the 2005 Outstanding Science Alumni Award from NUS.[4] She is the granddaughter of Tan Kah Kee and niece of Lee Kong Chian.[5]

Chinese origins of Hindu-Arabic Numerals Hypothesis[edit]

Lam Lay Yong has hypothesised that Hindu–Arabic numeral system originated in China based on her comparative studies on Chinese counting rods system. She states that the rod numerals and the hindu numerals have a few in common, that they're nine signs, concept of zero, a place value system, and decimal base.[6] She claims that, "While no one knows how the Hindu-Arabic system originates in India, on the other hand, there is strong evidence of a transmission of the concept of the rod system to India." She even claims that there is no unquestionable evidence that the system originated in India, and that she claims that there are two factors concerning this. One was from mathematician's mention, for example a critique of Severus Sebokht on Indian ingenuity, and Al-Khwarizmi's book on Hindu Calculation. The other factor is the presence of Brahmi numerals.[7]

However Michel Danino criticised this by saying that Lam Lay Yong's evidence for this was not at all evidence-based nor rigorous, and that she is ill-qualified for crosscultural studies. According to Michel Danino Her thesis has not been accepted, thus, the Chinese origin of Hindu-Arabic numerals remains to be hypothetical, and not widely accepted at all. All of this seems to contradict Yong's claims that there is strong evidence of rod numerals in India.[8]
