In the article on “Early History of the Hong Kong Observatory” published in the July 2021 issue of the HKLF Newsletter, we introduced the history of the Observatory from the time around the establishment of the Observatory to World War II. We now introduce the history and development of the Observatory since World War II…
有些数学问题是常人完全不能理解的，譬如黎曼猜想（Riemann hypothesis）需要用到不少高等数学知识才能解释；可是也有些问题是十岁小孩也能明白的。著名的孪生质数猜想（Twin Prime Conjecture）绝对能被归类为后者…
有些數學問題是常人完全不能理解的，譬如黎曼猜想（Riemann hypothesis）需要用到不少高等數學知識才能解釋；可是也有些問題是十歲小孩也能明白的。著名的孿生質數猜想（Twin Prime Conjecture）絕對能被歸類為後者…
There are math problems that are thoroughly incomprehensible to the layman – the Riemann hypothesis needs a fair amount of sophisticated math to explain, for example. And then there are those that even a ten-year-old could understand. The famous Twin Prime Conjecture is definitely in the latter category…
