Crowned as the "Father of Fibre Optics", "Father of Fibre Optic Communication" and "Godfather of Broadband", the 2009 "Nobel Laureate in Physics, Charles Kuen KAO is generally regarded as one of the most significant and influential contributors to engineering in modern times. His "groundbreaking achievements concerning the transmission of light in fibres for optical communication" was instrumental to the explosive development of the age of the Internet..…

Modern physics had its beginnings about a century ago with the birth of quantum mechanics. Over the past few decades, scientists have built on knowledge of electromagnetism to master the laws of the weak and strong interactions....

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…

Since 1841, Hong Kong became an important port of trade. In order to ensure smooth port operations and safe navigation of ships, there was a need to provide accurate time service…

In the previous issue, we learned that to meet the needs of ocean navigation, the British invented the marine chronometer to help captains accurately ascertain the longitude of the ship to ensure safe navigation. In spite of the high accuracy of the marine chronometers, they needed to be calibrated regularly, and this came to depend on a time service provided by major ports...

Since the early development in the 19th century, shipping has been the lifeblood of Hong Kong’s economy. To ensure smooth port operations and the safe navigation of ships, an accurate time service, meteorological observations and geomagnetic observations had to be provided...

Since ancient time, human’s livelihood is tightly related to weather. Farmer’s harvest depends on weather. As early as in the Shang Dynasty (13th century BC), there were written records of weather observations and weather predictions on oracle bone inscriptions…

Globalisation is a major trend in world development. With the popularisation of the Internet, communication technology has developed rapidly and encouraged spread of knowledge and exchange of ideas. Knowledge and scientific research are also going globalised. From basic scientific research to the development of innovative technology, there are rapid proliferation of cross-region and cross-discipline collaboration...
