About the Hong Kong Laureate Forum
Welcome to the March issue of the newsletter of the Hong Kong Laureate Forum. Whilst we are developing the week-long programme of the inaugural Forum, we are delighted to unveil some forum contents that may whet your appetite.
As the Forum aims to provide ample opportunities for idea exchanges between Shaw Laureates, globally renowned scientists and young scientists, apart from plenary lectures, panel discussions and parallel group sessions conducted by Shaw Laureates and distinguished scientists, there will be a number of dialogue events and opportunities in a close and direct manner, as well as young scientist presentation sessions for them to present their latest research ideas and spark everyone’s interest.
Three Scientific Review Committees on Mathematical Sciences, Life Science and Medicine, and Astronomy, to be chaired by our Council Chairman Prof Timothy TONG, Council members Prof the Hon TSUI Lap-chee and Prof Kenneth YOUNG respectively, will be formed to review young scientists’ applications.
Open application is scheduled to start in September 2020. We welcome undergraduates, postgraduates and PhD graduates who are aged 35 or below and studying or conducting research in Mathematical Sciences, Life Science and Medicine, and Astronomy or other closely related subjects to apply.
New look of our website has just been launched. A section on Science in the Community has been created to promote understanding and interests of the young generation in Hong Kong in various disciplines in science and technology.
To learn more about our programme, selection process and other information of our Forum, please stay tuned to our new website and social media!
Health and the Community
Health is important and essential to every living organism. It is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity. Health is determined by biological, social and lifestyle factors. A healthful lifestyle provides the means to lead a full life, which is continuously affected by the community and its environment. Community health, a growing discipline of public health, is the intersection of health care, economics and social interaction. In addition to health promotion and disease prevention, preparedness for disasters and curbing the spread of infectious diseases in the community are also top priority of community health programmes. Rigorous applied research provides the foundation to achieve the shared goal of attainment of healthier communities and quality of life for members. Community health workers, local government, volunteers, private sector and residents work in collaboration to improve and maintain the well-being of the community. In particular, community health practitioners also serve as home visitors and the first points of contact for health care. Primary care, including family and community medicine as well as traditional Chinese medicine, is starting to take shape with the launching of the Kwai Tsing District Health Centre Project in 2019. Hong Kong has learned from the experience of the 2003 SARS and is doing a good job in the preparedness and responses in the current COVID-19 pandemic. More can be done in better organised media strategy and public hand-washing provision. Thus, appropriate community health care should always be in the mind of the government, the academia and all stakeholders of the community. Ideally, community health programmes and local community networks should be integral parts of public health policy.

Interview with 2018 Shaw Laureate – Prof Jean-Loup Puget
The Shaw Prize in Astronomy 2018 was awarded to Prof Jean-Loup Puget for his contributions to astronomy in the infrared to submillimetre spectral range. He detected the cosmic far-infrared background from past star-forming galaxies, and proposed aromatic hydrocarbon molecules as a constituent of interstellar matter. With the Planck space mission, he has dramatically advanced our knowledge of cosmology in the presence of interstellar matter foregrounds.
An interview with Prof Puget was conducted by the Theoretical Astronomy Group of the
Hong Kong Astronomical Society (HKAS) in September 2018 and it was published at HKAS’s newsletter on 4th issue in 2018.
We are delighted to share the interview highlights provided by the HKAS.Scripts prepared by Dr Leung Chun Sing, Mr Fung Po Kei and Mr Eddie Ng
A History of π
To most people, 14th March is nothing but an ordinary day in a year. Yet to mathematics enthusiasts, it is Pi day, 3.14 is also the approximate value of π, Pi.
π doesn’t sound alien to most of us. The formula for finding the circumference (2πr) and area of a circle (πr2) are taught in the compulsory Mathematics subject in secondary school. π probably is one of the most well-known Mathematical constants but how many people know its origin and meanings?
π is defined as the ratio of a circle’s circumference to its diameter. If you can measure a circle’s circumference accurately and then divide its value by the diameter, the value of 3.141592654… will be displayed on the calculator. However, it is absolutely not the final answer, as π is an irrational number, which means it is a real number which cannot be expressed by a simple fraction. The reason it is rounded off to 3.141592654 is the display limitation of a calculator, with maximum 10 decimal places. Thus, many mathematics enthusiasts devote themselves into exploring the endless decimal places of π.
Ancient Babylonians calculated π to be about 3.125 by using ties and knots while ancient Egyptians calculated it to be roughly 3.16. In fact, Chinese mathematicians also made tremendous contribution in exploring π. During the Northern and Southern dynasties, mathematician Zu Chongzhi (429-500 AD) obtained the value of π which is precise to seven decimal places. According to “Record of Sui Almanac”, Zu deduced the value of π to be 3.1415927 which was held as the most accurate approximation of π for 1,000 years. This record was beaten by an Arabian mathematician Al-kashi whose value of π is precise to 16 decimal places in the 15th century. There is no book record of Zu’s calculation methods. It is commonly known that Zu cut the circle into a n-sided polygon and “n” is the side number of the polygon. When the number of “n” is larger, the polygon is closer to be a circle. It is said that Zu obtained the result by approximating a circle with a 24,576 sided polygon.
Thanks to the advances in technology, mathematicians nowadays can calculate π via advanced and efficient methods. 31 trillion digits are computed while more digits are being discovered. The study of π is the hard work of mathematicians brought into fruition over time and across many countries. Let’s see when we would have the next record for π!

健康與社區
健康對任何生物都是重要和基本的,健康不僅是沒有疾病,而是體格、精神與社會呈現整體健康狀態。健康受到生理、社會及生活模式等因素的影響。健康的生活模式極為需要的,並會帶來完美生活,但卻持續地受社區及環境因素影響。社區健康是一項發展中的公共衛生學科,它是醫護、經濟及社會互動的交接。除了推廣健康和預防疾病之外,為社區做好預防災難的準備和控制傳染病的散播是社區健康計劃最優先的任務。嚴格的應用研究,為實現更健康社區和提高成員生活質素的共同目標提供基礎。社區衛生工作者、地方政府、志願者、私營機構和居民之間共同合作去改善社區健康,而社區健康師亦作為家庭訪客,以及衛生保健的第一聯絡點。在2019年成立葵青地區康健中心時,基層醫護和健康(包括家庭和社區醫學及中醫藥)開始成形。香港從2003年的SARS經驗中吸取了教訓,在應對現今大流行的新型冠狀病毒 (COVID-19) 的防護準備和抗疫工作都做得很好;而在組織更佳的媒體策略和公共洗手方面,可以多做些工作。因此,合適的社區保健應常在政府、學術界和社區所有持分者的心中,最理想是把社區健康計劃方案和社區網路放進公共衛生政策的組成部分。

π之歷史
3月14日,可能只是一年中平平無奇的一天。但對熱愛數學的人來說,是與圓周率(π, Pi) 近似值3.14相同的一天,被稱為Pi day。
大家對π這個符號一定不會陌生:求圓周公式2πr、求圓面積公式πr2等等,都是中學數學必修內容,更可能是最多人認識的數學常數之一,但大家又知不知 π 的起源及意義?
π 是圓周(圓的周界)與直徑的比例。假如你能準確地量度一個圓形的圓周,再將該數值除以直徑,計算機將顯示3.141592654…的數值。然而,這絕不是最終答案。π 是一個無理數(irrational number),即是一個非循環的小數,只因為一般計算機只能顯示10個位,才會在3.141592654停下來。亦正因如此,發掘 π 無窮盡的小數位成為很多數學人的志業。
古巴比倫人用繩結計算出π的約數為3.125;古埃及人更將近似值準確至3.16。其實中國數學家對 π 也有重大貢獻,南北朝時期數學家祖沖之(429年 – 500年)將 π 的近似值準確至小數點後7位數字。按《隋書.律曆志》記載,祖沖之計算出 π 的值為約3.1415927,這個紀錄直至15世紀,即1000年後才被阿拉伯數學家阿爾.卡西以小數點後16位數字打破。由於古籍缺欠,祖沖之計算 π 的方法沒有準確的說法,普遍認為他是將圓切割為一個N邊等邊形,N是多邊形的邊的數目。當N越大,該多邊形就與圓形越相似。據說,祖沖之將圓形分割到24576形。
隨着科技進步,數學家計算 π 的方法已十分先進及有效率,今天對 π 的研究已去到31萬億個位,同時紀錄亦不斷被打破。π 的研究是古今中外數學家努力的成果,讓我們一起期待下一次 π 被打破的時候吧!
