Aberdeen Tunnel Underground Laboratory
The Aberdeen Tunnel Underground Laboratory () is the only underground particle physics laboratory in Hong Kong. It is situated between the two vehicular tunnel tubes, behind Gates 2 and 5 of Aberdeen Tunnel on Hong Kong Island. History Commissioned by the University of Hong Kong (HKU) after an assessment of all existing tunnels in Hong Kong, the location of the Aberdeen Tunnel, then under construction in the valley between Mount Cameron and Mount Nicholson, was deemed the most suitable site for undertaking particle physics experimentation. Funded entirely by HKU, construction work on the laboratory was completed in 1980. The laboratory was practically abandoned after HKU researchers completed their experiments, as no other experiments of a similar nature made further use of the facility. However, in 2006, HKU and the Chinese University of Hong Kong petitioned the Aberdeen Tunnel administration for permission to reuse the laboratory, in order to participate in a Daya Bay Reactor ...

Particle Physics
Particle physics or high energy physics is the study of fundamental particles and forces that constitute matter and radiation. The fundamental particles in the universe are classified in the Standard Model as fermions (matter particles) and bosons (force-carrying particles). There are three generations of fermions, but ordinary matter is made only from the first fermion generation. The first generation consists of up and down quarks which form protons and neutrons, and electrons and electron neutrinos. The three fundamental interactions known to be mediated by bosons are electromagnetism, the weak interaction, and the strong interaction. Quarks cannot exist on their own but form hadrons. Hadrons that contain an odd number of quarks are called baryons and those that contain an even number are called mesons. Two baryons, the proton and the neutron, make up most of the mass of ordinary matter. Mesons are unstable and the longest-lived last for only a few hundredths of ...

Science And Technology In Hong Kong
Science is a systematic endeavor that builds and organizes knowledge in the form of testable explanations and predictions about the universe. Science may be as old as the human species, and some of the earliest archeological evidence for scientific reasoning is tens of thousands of years old. The earliest written records in the history of science come from Ancient Egypt and Mesopotamia in around 3000 to 1200 BCE. Their contributions to mathematics, astronomy, and medicine entered and shaped Greek natural philosophy of classical antiquity, whereby formal attempts were made to provide explanations of events in the physical world based on natural causes. After the fall of the Western Roman Empire, knowledge of Greek conceptions of the world deteriorated in Western Europe during the early centuries (400 to 1000 CE) of the Middle Ages, but was preserved in the Muslim world during the Islamic Golden Age and later by the efforts of Byzantine Greek scholars who brought Greek ma ...

Particle Physics Facilities
In the physical sciences, a particle (or corpuscule in older texts) is a small localized object which can be described by several physical or chemical properties, such as volume, density, or mass. They vary greatly in size or quantity, from subatomic particles like the electron, to microscopic particles like atoms and molecules, to macroscopic particles like powders and other granular materials. Particles can also be used to create scientific models of even larger objects depending on their density, such as humans moving in a crowd or celestial bodies in motion. The term ''particle'' is rather general in meaning, and is refined as needed by various scientific fields. Anything that is composed of particles may be referred to as being particulate. However, the noun ''particulate'' is most frequently used to refer to pollutants in the Earth's atmosphere, which are a suspension of unconnected particles, rather than a connected particle aggregation.

National United University
The National United University (NUU; ; Pha̍k-fa-sṳ: ''Kwet-li̍p Lîen-ha̍p Thài-ho̍k'') is a public university in Miaoli City, Miaoli County, Taiwan. History The school (then a two-year private junior college) started its first semester in September 1972 as Lien Ho Industrial and Technological Junior College. The college was the only higher education institution in the Miaoli region at the time. On 1 August 1973, it was renamed to Lien Ho Junior College of Technology. In 1992 the college was renamed Lien Ho College of Technology and Commerce.

Laboratory
A laboratory (; ; colloquially lab) is a facility that provides controlled conditions in which scientific or technological research, experiments, and measurement may be performed. Laboratory services are provided in a variety of settings: physicians' offices, clinics, hospitals, and regional and national referral centers. Overview The organisation and contents of laboratories are determined by the differing requirements of the specialists working within. A physics laboratory might contain a particle accelerator or vacuum chamber, while a metallurgy laboratory could have apparatus for casting or refining metals or for testing their strength. A chemist or biologist might use a wet laboratory, while a psychologist's laboratory might be a room with one-way mirrors and hidden cameras in which to observe behavior. In some laboratories, such as those commonly used by computer scientists, computers (sometimes supercomputers) are used for either simulations or the analysis of data. Scient ...
