Bomb Calorimeter
A bomb is an explosive weapon that uses the exothermic reaction of an explosive material to provide an extremely sudden and violent release of energy. Detonations inflict damage principally through ground- and atmosphere-transmitted mechanical stress, the impact and penetration of pressure-driven projectiles, pressure damage, and explosion-generated effects. Bombs have been utilized since the 11th century starting in East Asia. The term bomb is not usually applied to explosive devices used for civilian purposes such as construction or mining, although the people using the devices may sometimes refer to them as a "bomb". The military use of the term "bomb", or more specifically aerial bomb action, typically refers to airdropped, unpowered explosive weapons most commonly used by air forces and naval aviation. Other military explosive weapons not classified as "bombs" include shells, depth charges (used in water), or land mines. In unconventional warfare, other names can refer t ...

Saarlouis Bombe
Saarlouis (; french: link=no, Sarrelouis, ; formerly Sarre-Libre and Saarlautern) is a town in Saarland, Germany, capital of the district of Saarlouis. In 2020, the town had a population of 34,409. Saarlouis, as the name implies, is located on the river Saar. It was built as a fortress in 1680 and was named after Louis XIV of France. History With the Treaties of Peace of Nijmegen in 1678/79, Lorraine fell to France. In 1680, Louis XIV of France gave orders to build a fortification (to defend the new French eastern frontier) on the banks of the river Saar which was called ''Sarre-Louis''. Notable French military engineer, Sébastien Le Prestre de Vauban, constructed the town, which would serve as the capital of the Province de la Sarre. The plans were made by Thomas de Choisy, the town's first Gouvenour. In 1683, Louis XIV visited the fortress and granted arms. The coat of arms shows the rising sun and three Fleur-de-lis.

Unconventional Warfare
Unconventional warfare (UW) is broadly defined as "military and quasi-military operations other than conventional warfare" and may use covert forces, subversion, or guerrilla warfare. This is typically done to avoid escalation into conventional warfare as well as international conventions. Description Aside from the earlier definition of warfare that is not conventional, unconventional warfare has also been described as: There is another type of warfare— new in its intensity, ancient in its origin—war by guerrillas, subversives, insurgents, assassins; war by ambush instead of by combat, by infiltration instead of aggression, seeking victory by eroding and exhausting the enemy instead of engaging him. It preys on unrest. Methods and organization Unconventional warfare targets the civilian population psychologically to win hearts and minds, and only targets military and political bodies for that purpose, seeking to render the military proficiency of the enemy irrelev ...

Subutai
Subutai (Classical Mongolian: ''Sübügätäi'' or ''Sübü'ätäi''; Modern Mongolian: Сүбээдэй, ''Sübeedei''. ; ; c. 1175–1248) was a Mongol general and the primary military strategist of Genghis Khan and Ögedei Khan. He directed more than 20 campaigns and won 65 pitched battles, during which he conquered or overran more territory than any other commander in history as part of the expansion of the Mongol Empire, the largest contiguous empire in human history. He often gained victory by means of imaginative and sophisticated strategies and routinely coordinated movements of armies that operated hundreds of kilometers apart from each other. Subutai is well known for the geographical diversity and success of his expeditions, which took him from central Asia to the Russian steppe and into Europe. He is widely regarded as one of the greatest military commanders and strategists in history. Early life Historians believe Subutai was born in the year 1175, probably just we ...

Song Dynasty
The Song dynasty (; ; 960–1279) was an imperial dynasty of China that began in 960 and lasted until 1279. The dynasty was founded by Emperor Taizu of Song following his usurpation of the throne of the Later Zhou. The Song conquered the rest of the Ten Kingdoms, ending the Five Dynasties and Ten Kingdoms period. The Song often came into conflict with the contemporaneous Liao, Western Xia and Jin dynasties in northern China. After retreating to southern China, the Song was eventually conquered by the Mongol-led Yuan dynasty. The dynasty is divided into two periods: Northern Song and Southern Song. During the Northern Song (; 960–1127), the capital was in the northern city of Bianjing (now Kaifeng) and the dynasty controlled most of what is now Eastern China. The Southern Song (; 1127–1279) refers to the period after the Song lost control of its northern half to the Jurchen-led Jin dynasty in the Jin–Song Wars. At that time, the Song court retreated south of the ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Jin Dynasty (1115–1234)
The Jin dynasty (, ; ) or Jin State (; Jurchen: Anchun Gurun), officially known as the Great Jin (), was an imperial dynasty of China that existed between 1115 and 1234. Its name is sometimes written as Kin, Jurchen Jin, Jinn, or Chin in English to differentiate it from an earlier Jìn dynasty whose name is rendered identically in Hanyu Pinyin without the tone marking. It is also sometimes called the "Jurchen dynasty" or the "Jurchen Jin", because members of the ruling Wanyan clan were of Jurchen descent. The Jin emerged from Wanyan Aguda's rebellion against the Liao dynasty (916–1125), which held sway over northern China until the nascent Jin drove the Liao to the Western Regions, where they became known in historiography as the Western Liao. After vanquishing the Liao, the Jin launched a century-long campaign against the Han-led Song dynasty (960–1279), which was based in southern China. Over the course of their rule, the ethnic Jurchen emperors of the Jin dynas ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Wind And Dust Bomb
Wind is the natural movement of air or other gases relative to a planet's surface. Winds occur 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 and subtropics, 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 prevail. Winds are commonly classified by their spatial scale, their speed and direction, the forces that cause them, the regions in which they occur, and their effect. Winds have variou ...

Onomatopoeia
Onomatopoeia is the process of creating a word that phonetically imitates, resembles, or suggests the sound that it describes. Such a word itself is also called an onomatopoeia. Common onomatopoeias include animal noises such as ''oink'', ''meow'' (or ''miaow''), ''roar'', and ''chirp''. Onomatopoeia can differ between languages: it conforms to some extent to the broader linguistic system; hence the sound of a clock may be expressed as ''tick tock'' in English, in Spanish and Italian (shown in the picture), in Mandarin, in Japanese, or in Hindi. The English term comes from the Ancient Greek compound ''onomatopoeia'', 'name-making', composed of ''onomato''- 'name' and -''poeia'' 'making'. Thus, words that imitate sounds can be said to be onomatopoeic or onomatopoetic. Uses In the case of a frog croaking, the spelling may vary because different frog species around the world make different sounds: Ancient Greek (only in Aristophanes' comic play ''The Frogs'') probably ...

Romanized
Romanization or romanisation, in linguistics, is the conversion of text from a different writing system to the Roman (Latin) script, or a system for doing so. Methods of romanization include transliteration, for representing written text, and transcription, for representing the spoken word, and combinations of both. Transcription methods can be subdivided into ''phonemic transcription'', which records the phonemes or units of semantic meaning in speech, and more strict ''phonetic transcription'', which records speech sounds with precision. Methods There are many consistent or standardized romanization systems. They can be classified by their characteristics. A particular system’s characteristics may make it better-suited for various, sometimes contradictory applications, including document retrieval, linguistic analysis, easy readability, faithful representation of pronunciation. * Source, or donor language – A system may be tailored to romanize text from a particular lang ...
