Wei Boyang
Wei Boyang () was a notable Chinese writer and Taoist alchemist of the Eastern Han Dynasty. He is the author of ''The Kinship of the Three'', and is noted as the first person to have documented the chemical composition of gunpowder in 142 AD.Peng, Yoke Ho. 000(2000).

History Of Gunpowder
Gunpowder is the first explosive to have been developed. Popularly listed as one of the " Four Great Inventions" of China, it was invented during the late Tang dynasty (9th century) while the earliest recorded chemical formula for gunpowder dates to the Song dynasty (11th century). Knowledge of gunpowder spread rapidly throughout Asia and Europe, possibly as a result of the Mongol conquests during the 13th century, with written formulas for it appearing in the Middle East between 1240 and 1280 in a treatise by Hasan al-Rammah, and in Europe by 1267 in the '' Opus Majus'' by Roger Bacon. It was employed in warfare to some effect from at least the 10th century in weapons such as fire arrows, bombs, and the fire lance before the appearance of the gun in the 13th century. While the fire lance was eventually supplanted by the gun, other gunpowder weapons such as rockets and fire arrows continued to see use in China, Korea, India, and eventually Europe. Bombs too never ceased to ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Gunpowder
Gunpowder, also commonly known as black powder to distinguish it from modern smokeless powder, is the earliest known chemical explosive. It consists of a mixture of sulfur, carbon (in the form of charcoal) and potassium nitrate ( saltpeter). The sulfur and carbon act as fuels while the saltpeter is an oxidizer. Gunpowder has been widely used as a propellant in firearms, artillery, rocketry, and pyrotechnics, including use as a blasting agent for explosives in quarrying, mining, building pipelines and road building. Gunpowder is classified as a low explosive because of its relatively slow decomposition rate and consequently low brisance. Low explosives deflagrate (i.e., burn at subsonic speeds), whereas high explosives detonate, producing a supersonic shockwave. Ignition of gunpowder packed behind a projectile generates enough pressure to force the shot from the muzzle at high speed, but usually not enough force to rupture the gun barrel. It thus makes a good pro ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Ancient Alchemists
Ancient history is a time period from the beginning of writing and recorded human history to as far as late antiquity. The span of recorded history is roughly 5,000 years, beginning with the Sumerian cuneiform script. Ancient history covers all continents inhabited by humans in the period 3000 BCAD 500. The three-age system periodizes ancient history into the Stone Age, the Bronze Age, and the Iron Age, with recorded history generally considered to begin with the Bronze Age. The start and end of the three ages varies between world regions. In many regions the Bronze Age is generally considered to begin a few centuries prior to 3000 BC, while the end of the Iron Age varies from the early first millennium BC in some regions to the late first millennium AD in others. During the time period of ancient history, the world population was already Exponential growth, exponentially increasing due to the Neolithic Revolution, which was in full progress. While in 10,000 BC, the world ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Taoism
Taoism (, ) or Daoism () refers to either a school of philosophical thought (道家; ''daojia'') or to a religion (道教; ''daojiao''), both of which share ideas and concepts of Chinese origin and emphasize living in harmony with the '' Tao'' (, 'Thoroughfare'); the ''Tao'' is generally defined as the source of everything and the ultimate principle underlying reality. The '' Tao Te Ching'', a book containing teachings attributed to Laozi (), together with the later writings of Zhuangzi, are both widely considered the keystone works of Taoism. Taoism teaches about the various disciplines for achieving perfection through self-cultivation. This can be done through the use of Taoist techniques and by becoming one with the unplanned rhythms of the all, called "the way" or "Tao". Taoist ethics vary depending on the particular school, but in general tend to emphasize ''wu wei'' (action without intention), naturalness, simplicity, spontaneity and the Three Treasures: , compassio ...

Chinese Alchemy
Chinese alchemy is an ancient Chinese scientific and technological approach to alchemy, a part of the larger tradition of Taoist / Daoist body-spirit cultivation developed from the traditional Chinese understanding of medicine and the body. According to original texts such as the Cantong qi, the body is understood as the focus of cosmological processes summarized in the five agents of change, or Wuxing, the observation and cultivation of which leads the practitioner into alignment and harmony with the Tao. Therefore, the traditional view in China is that alchemy focuses mainly on longevity and the purification of one's spirit, mind and body, providing, health, longevity and wisdom, through the practice of Qigong, wuxingheqidao. The consumption and use of various concoctions known as alchemical medicines or elixirs, each of which having different purposes but largely were concerned with immortality.

Cantong Qi
The ''Cantong qi'' is deemed to be the earliest book on Taoist alchemy in China. The title has been variously translated as ''Kinship of the Three'', ''Akinness of the Three'', ''Triplex Unity'', ''The Seal of the Unity of the Three'', and in several other ways. The full title of the text is ''Zhouyi cantong qi'', which can be translated as, for example, ''The Kinship of the Three, in Accordance with the Book of Changes''. According to the traditional view, well-established in China, the text was composed by Wei Boyang in the mid-second century CE, and deals entirely with alchemy—in particular, with Neidan, or Internal Alchemy. Besides this one, there has been, within the Taoist tradition, a second way of reading the text: in agreement with its title, the ''Cantong qi'' is concerned not with one, but with three major subjects, namely Cosmology (the system of the '' Book of Changes)'', Taoism (the way of "non-doing"), and Alchemy, and joins them to one another into a single d ...

Anno Domini
The terms (AD) and before Christ (BC) are used to label or number years in the Julian and Gregorian calendars. The term is Medieval Latin and means 'in the year of the Lord', but is often presented using "our Lord" instead of "the Lord", taken from the full original phrase "''anno Domini nostri Jesu Christi''", which translates to 'in the year of our Lord Jesus Christ'. The form "BC" is specific to English and equivalent abbreviations are used in other languages: the Latin form is but is rarely seen. This calendar era is based on the traditionally reckoned year of the conception or birth of Jesus, ''AD'' counting years from the start of this epoch and ''BC'' denoting years before the start of the era. There is no year zero in this scheme; thus ''the year AD 1 immediately follows the year 1 BC''. This dating system was devised in 525 by Dionysius Exiguus, but was not widely used until the 9th century. Traditionally, English follows Latin usage by placing the ...
