Encyclopedic Dictionary of Vietnam

Từ điển bách khoa Việt Nam (Literally Encyclopaedic Dictionary of Vietnam) is a state-sponsored Vietnamese language encyclopedia that was published in Vietnam in 2005.

It is the first state encyclopedia of the Socialist Republic of Vietnam. The compilation process began in 1987 and was completed in 2005.[1] The first edition, published in 2005 by Vietnam's Encyclopedia Publishing House, has four volumes consisting of 40,000 entries.[2] Arranged by Vietnamese-alphabet order, the encyclopedia covers topics from historical to child rearing. Since then, it has been converted to electronic versions (CD and ebook) and a free online version.

3rd Corps (Vietnam People's Army)

3rd Corps (Vietnamese: Quân đoàn 3) or Tây Nguyên Corps (Vietnamese: Binh doan tay nguyen, literally: Corps of Tây Nguyên or Corps of the Western Highlands) is one of the four regular army corps of the Vietnam People's Army. First organised in 1975 during the Vietnam War, 3rd Corps had a major role in the Ho Chi Minh Campaign and the Cambodian–Vietnamese War. Today the corps is stationed in Pleiku, Gia Lai.

Antiparticle

In particle physics, every type of particle has an associated antiparticle with the same mass but with opposite physical charges (such as electric charge). For example, the antiparticle of the electron is the antielectron (which is often referred to as positron). While the electron has a negative electric charge, the positron has a positive electric charge, and is produced naturally in certain types of radioactive decay. The opposite is also true: the antiparticle of the positron is the electron.

Some particles, such as the photon, are their own antiparticle. Otherwise, for each pair of antiparticle partners, one is designated as normal matter (the kind all matter usually interacted with is made of), and the other (usually given the prefix "anti-") as antimatter.

Particle–antiparticle pairs can annihilate each other, producing photons; since the charges of the particle and antiparticle are opposite, total charge is conserved. For example, the positrons produced in natural radioactive decay quickly annihilate themselves with electrons, producing pairs of gamma rays, a process exploited in positron emission tomography.

The laws of nature are very nearly symmetrical with respect to particles and antiparticles. For example, an antiproton and a positron can form an antihydrogen atom, which is believed to have the same properties as a hydrogen atom. This leads to the question of why the formation of matter after the Big Bang resulted in a universe consisting almost entirely of matter, rather than being a half-and-half mixture of matter and antimatter. The discovery of Charge Parity violation helped to shed light on this problem by showing that this symmetry, originally thought to be perfect, was only approximate.

Because charge is conserved, it is not possible to create an antiparticle without either destroying another particle of the same charge (as is for instance the case when antiparticles are produced naturally via beta decay or the collision of cosmic rays with Earth's atmosphere), or by the simultaneous creation of both a particle and its antiparticle, which can occur in particle accelerators such as the Large Hadron Collider at CERN.

Although particles and their antiparticles have opposite charges, electrically neutral particles need not be identical to their antiparticles. The neutron, for example, is made out of quarks, the antineutron from antiquarks, and they are distinguishable from one another because neutrons and antineutrons annihilate each other upon contact. However, other neutral particles are their own antiparticles, such as photons, Z0 bosons, π0 mesons, and hypothetical gravitons and some hypothetical WIMPs.

Light

Light is electromagnetic radiation within a certain portion of the electromagnetic spectrum. The word usually refers to visible light, which is the visible spectrum that is visible to the human eye and is responsible for the sense of sight. Visible light is usually defined as having wavelengths in the range of 400–700 nanometres (nm), or 4.00 × 10−7 to 7.00 × 10−7 m, between the infrared (with longer wavelengths) and the ultraviolet (with shorter wavelengths). This wavelength means a frequency range of roughly 430–750 terahertz (THz).

The main source of light on Earth is the Sun. Sunlight provides the energy that green plants use to create sugars mostly in the form of starches, which release energy into the living things that digest them. This process of photosynthesis provides virtually all the energy used by living things. Historically, another important source of light for humans has been fire, from ancient campfires to modern kerosene lamps. With the development of electric lights and power systems, electric lighting has effectively replaced firelight. Some species of animals generate their own light, a process called bioluminescence. For example, fireflies use light to locate mates, and vampire squids use it to hide themselves from prey.

The primary properties of visible light are intensity, propagation direction, frequency or wavelength spectrum, and polarization, while its speed in a vacuum, 299,792,458 metres per second, is one of the fundamental constants of nature. Visible light, as with all types of electromagnetic radiation (EMR), is experimentally found to always move at this speed in a vacuum.In physics, the term light sometimes refers to electromagnetic radiation of any wavelength, whether visible or not. In this sense, gamma rays, X-rays, microwaves and radio waves are also light. Like all types of EM radiation, visible light propagates as waves. However, the energy imparted by the waves is absorbed at single locations the way particles are absorbed. The absorbed energy of the EM waves is called a photon, and represents the quanta of light. When a wave of light is transformed and absorbed as a photon, the energy of the wave instantly collapses to a single location, and this location is where the photon "arrives." This is what is called the wave function collapse. This dual wave-like and particle-like nature of light is known as the wave–particle duality. The study of light, known as optics, is an important research area in modern physics.

Longest words

The longest word in any given language depends on the word formation rules of each specific language, and on the types of words allowed for consideration.

Agglutinative languages allow for the creation of long words via compounding. Words consisting of hundreds, or even thousands of characters have been coined. Even non-agglutinative languages may allow word formation of theoretically limitless length in certain contexts. An example common to many languages in the term for a very remote ancestor, "great-great-.....-grandfather", where the prefix "great-" may be repeated any number of times.

Systematic names of chemical compounds can run to hundreds of thousands of characters in length. The rules of creation of such names are commonly defined by international bodies, therefore they formally belong to many languages. The longest recognized systematic name is for the protein titin, at 189,819 letters. While lexicographers regard generic names of chemical compounds as verbal formulae rather than words, for its sheer length the systematic name for titin is often included in longest-word lists.

Longest word candidates may be judged by their acceptance in major dictionaries such as the Oxford English Dictionary or in record-keeping publications like Guinness World Records, and by the frequency of their use in ordinary language.

The Tale of Kieu

The Tale of Kiều is an epic poem in Vietnamese written by Nguyễn Du (1765–1820), and is widely regarded as the most significant work of Vietnamese literature. The original title in Vietnamese is Đoạn Trường Tân Thanh (斷腸新聲, "A New Cry From a Broken Heart"), but it is better known as Truyện Kiều (傳翹, IPA: [ʈʂwîənˀ kîəw] (listen), lit. "Tale of Kiều").

In 3,254 verses, written in lục bát ("six–eight") meter, the poem recounts the life, trials and tribulations of Thúy Kiều, a beautiful and talented young woman, who has to sacrifice herself to save her family. To save her father and younger brother from prison, she sells herself into marriage with a middle-aged man, not knowing that he is a pimp, and is forced into prostitution. While modern interpretations vary, some post-colonial writers have interpreted it as a critical, allegorical reflection on the rise of the Nguyễn dynasty.Nguyễn Du made use of the plot of a seventeenth-century Chinese novel, Jīn Yún Qiào (Chinese: 金雲翹), known in Vietnamese pronunciation of Chinese characters as Kim Vân Kiều. The original, written by an otherwise unknown writer under the pseudonym Qīngxīn Cáirén (Chinese: 青心才人 "Pure-Hearted Man of Talent"), was a straightforward romance, but Nguyễn Du chose it to convey the social and political upheavals at the end of the 18th century in Vietnam.Vietnam at that time was ruled nominally by the 300-year-old Lê dynasty, but real power rested in the Trịnh lords in the north and the Nguyễn lords in the south. While the Trịnh and the Nguyễn were fighting against each other, the Tây Sơn rebels overthrew both the Nguyễn and then the Trịnh over the span of a decade. Nguyễn Du was loyal to the Lê Dynasty and hoped for the return of the Lê king. In 1802 the Nguyễn lord Nguyễn Ánh conquered all of Vietnam forming the new Nguyễn dynasty. Nguyễn Ánh, now Emperor Gia Long, summoned Nguyễn Du to join the new government and, with some reluctance, he did so. Nguyễn Du's situation in terms of conflicting loyalties between the previous Lê king and the current Nguyễn emperor is partially analogous to the situation of the main character in The Tale of Kiều who submitted to circumstances but her heart longed for her first love.

Trương Tấn Bửu

Trương Tấn Bửu (張進寶, 1752–1827), also called Trương Tấn Long (張進隆), was a general and official of the Nguyễn dynasty of Vietnam

He was born in 1752 in Thạch Phú Đông, Giồng Trôm District, Bến Tre Province. In 1797, he joined the army of Nguyễn Ánh and became a đốc chiêu cai cơ (commander). Later, he became the Deputy Marshal of the Nguyễn's Army's Front Division. In 1802, after the unification of Vietnam, he became the military commander of Nguyen's armies in northern Vietnam and later the Viceroy of Bắc Thành. In 1816, he became the Deputy Marshal of the Nguyễn Army's Central Division which guarding Huế, the capital of Nguyễn dynasty. In 1823, he took up the post of Viceroy of Gia Định replacing Lê Văn Duyệt. Shortly thereafter, he retired because of illness and then died in 1827 at the age of 75.

Vĩnh Tế Canal

The Vĩnh Tế Canal (Vietnamese: Kênh Vĩnh Tế, Khmer: ព្រែកជីក or ព្រែកយួន) is an 87-kilometre-long (54 mi) canal in southern Vietnam, designed to give the territory of Châu Đốc a direct access to the Hà Tiên sea gate, Gulf of Siam.After the construction of Thoai Ha Canal, Emperor Gia Long of Nguyễn Dynasty ordered the mandarin Nguyễn Văn Thoại to dig a new canal along the Cambodian–Vietnamese border. The emperor's edict said: "Công trình đào sông này rất là khó khăn, nhưng kế giữ nước và cách biên phòng quan hệ chẳng nhỏ, chúng người tuy rằng ngày nay chịu khó, nhưng mà ích lợi cho muôn đời về sau..." (..this canal-digging project is tough, but its role in [our] national security and national defense is not small, we should accept the hardship so that our descendants would have the benefit ..).The construction of the canal was started in the end of 1819. The project used about 80,000 local Vietnamese and Khmer workers. After the death of Emperor Gia Long, the succeeding Emperor Minh Mạng continued the project. The workers, especially the Khmers, were heavily exploited by being forced to do hard work, which resulted thousands of deaths from fatigue and consequent disease during the canal's construction. Consequently, the Vinh Te Canal became a symbol of Vietnamese mistreatment of the Khmer and was used later by the Khmer Rouge in anti-Vietnamese propaganda. The construction was completed in 1824 and Emperor Minh Mạng named the canal after Châu Vĩnh Tế, the wife of its builder Nguyen Van Thoai. From that point on, the canal plays an important role in the southern Vietnam's communication, transportation and the definition of the border of Vietnam and Cambodia.

Wind

Wind is the flow of gases on a large scale. On the surface of the Earth, wind consists of the bulk movement of air. In outer space, solar wind is the movement of gases or charged particles from the Sun through space, while planetary wind is the outgassing of light chemical elements from a planet's atmosphere into space. Winds are commonly classified by their spatial scale, their speed, the types of forces that cause them, the regions in which they occur, and their effect. The strongest observed winds on a planet in the Solar System occur on Neptune and Saturn. Winds have various aspects, an important one being its velocity (wind speed); another the density of the gas involved; another its energy content or wind energy. Wind is also a great source of transportation for seeds and small birds; with time things can travel thousands of miles in the wind.

In meteorology, winds are often referred to according to their strength, and the direction from which the wind is blowing. Short bursts of high-speed wind are termed gusts. Strong winds of intermediate duration (around one minute) are termed squalls. Long-duration winds have various names associated with their average strength, such as breeze, gale, storm, and hurricane. Wind occurs on a range of scales, from thunderstorm flows lasting tens of minutes, to local breezes generated by heating of land surfaces and lasting a few hours, to global winds resulting from the difference in absorption of solar energy between the climate zones on Earth. The two main causes of large-scale atmospheric circulation are the differential heating between the equator and the poles, and the rotation of the planet (Coriolis effect). Within the tropics, thermal low circulations over terrain and high plateaus can drive monsoon circulations. In coastal areas the sea breeze/land breeze cycle can define local winds; in areas that have variable terrain, mountain and valley breezes can dominate local winds.

In human civilization, the concept of wind has been explored in mythology, influenced the events of history, expanded the range of transport and warfare, and provided a power source for mechanical work, electricity and recreation. Wind powers the voyages of sailing ships across Earth's oceans. Hot air balloons use the wind to take short trips, and powered flight uses it to increase lift and reduce fuel consumption. Areas of wind shear caused by various weather phenomena can lead to dangerous situations for aircraft. When winds become strong, trees and human-made structures are damaged or destroyed.

Winds can shape landforms, via a variety of aeolian processes such as the formation of fertile soils, such as loess, and by erosion. Dust from large deserts can be moved great distances from its source region by the prevailing winds; winds that are accelerated by rough topography and associated with dust outbreaks have been assigned regional names in various parts of the world because of their significant effects on those regions. Wind also affects the spread of wildfires. Winds can disperse seeds from various plants, enabling the survival and dispersal of those plant species, as well as flying insect populations. When combined with cold temperatures, wind has a negative impact on livestock. Wind affects animals' food stores, as well as their hunting and defensive strategies.
