1852 In Oregon Territory
Year 185 ( CLXXXV) was a common year starting on Friday of the Julian calendar. At the time, it was known as the Year of the Consulship of Lascivius and Atilius (or, less frequently, year 938 ''Ab urbe condita''). The denomination 185 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Roman Numerals
Roman numerals are a numeral system that originated in ancient Rome and remained the usual way of writing numbers throughout Europe well into the Late Middle Ages. Numbers are written with combinations of letters from the Latin alphabet, each with a fixed integer value. The modern style uses only these seven: The use of Roman numerals continued long after the Fall of the Western Roman Empire, decline of the Roman Empire. From the 14th century on, Roman numerals began to be replaced by Arabic numerals; however, this process was gradual, and the use of Roman numerals persisted in various places, including on clock face, clock faces. For instance, on the clock of Big Ben (designed in 1852), the hours from 1 to 12 are written as: The notations and can be read as "one less than five" (4) and "one less than ten" (9), although there is a tradition favouring the representation of "4" as "" on Roman numeral clocks. Other common uses include year numbers on monuments and buildin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yuezhi
The Yuezhi were an ancient people first described in China, Chinese histories as nomadic pastoralists living in an arid grassland area in the western part of the modern Chinese province of Gansu, during the 1st millennium BC. After a major defeat at the hands of the Xiongnu in 176 BC, the Yuezhi split into two groups migrating in different directions: the Greater Yuezhi and Lesser Yuezhi. This started a complex domino effect that radiated in all directions and, in the process, set the course of history for much of Asia for centuries to come. The Greater Yuezhi initially migrated northwest into the Ili River, Ili Valley (on the modern borders of China and Kazakhstan), where they reportedly displaced elements of the Sakas. They were driven from the Ili Valley by the Wusun and migrated southward to Sogdia and later settled in Bactria. The Greater Yuezhi have consequently often been identified with peoples mentioned in classical European sources as having overrun the Greco-Bactrian K ...

Gospels
Gospel originally meant the Christian message (" the gospel"), but in the second century AD the term (, from which the English word originated as a calque) came to be used also for the books in which the message was reported. In this sense a gospel can be defined as a loose-knit, episodic narrative of the words and deeds of Jesus, culminating in his trial and death, and concluding with various reports of his post-resurrection appearances. The Gospels are commonly seen as literature that is based on oral traditions, Christian preaching, and Old Testament exegesis with the consensus being that they are a variation of Greco-Roman biography; similar to other ancient works such as Xenophon's ''Memoirs of Socrates''. They are meant to convince people that Jesus was a charismatic miracle-working holy man, providing examples for readers to emulate. As such, they present the Christian message of the second half of the first century AD, Modern biblical scholars are therefore ca ...

Irenaeus
Irenaeus ( or ; ; ) was a Greeks, Greek bishop noted for his role in guiding and expanding Christianity, Christian communities in the southern regions of present-day France and, more widely, for the development of Christian theology by opposing Gnostic interpretations of Christian Scripture and defining proto-orthodoxy. Originating from Smyrna, he had seen and heard the preaching of Polycarp, who in turn was said to have heard John the Evangelist. Chosen as Roman Catholic Archdiocese of Lyon, Bishop of Lugdunum, now Lyon, Irenaeus wrote his best-known work ''Against Heresies (Irenaeus), Against Heresies'' around 180 as a refutation of gnosticism, in particular that of Valentinus (Gnostic), Valentinus. To counter the doctrines of the gnostic sects claiming Sophia (gnosticism), secret wisdom, he offered three pillars of orthodoxy: the Bible, scriptures, the Apostolic Tradition, tradition said to be handed down from the apostles, and the teaching of the apostles' Apostolic succ ...

Chinese Astronomy
Astronomy in China has a long history stretching from the Shang dynasty, being refined over a period of more than 3,000 years. The Ancient China, ancient Chinese people have identified stars from 1300 BCE, as Chinese star names later categorized in the twenty-eight mansions have been found on oracle bones unearthed at Anyang, dating back to the mid-Shang dynasty. The core of the "mansion" (宿 ''xiù'') system also took shape around this period, by the time of King Wu Ding (1250–1192 BCE). Detailed records of astronomical observations began during the Warring States period (fourth century BCE). They flourished during the Han period (202 BCE – 220 CE) and subsequent dynasties with the publication of star catalogues. Chinese astronomy was equatorial, centered on close observation of circumpolar stars, and was based on different principles from those in traditional Western astronomy, where heliacal risings and settings of zodiac constellations formed the basic ecliptic framew ...

SN 185
SN 185 was a transient astronomical event observed in the year AD 185, likely a supernova A supernova (: supernovae or supernovas) is a powerful and luminous explosion of a star. A supernova occurs during the last stellar evolution, evolutionary stages of a massive star, or when a white dwarf is triggered into runaway nuclear fusion .... The transient occurred in the direction of Alpha Centauri, between the constellations Circinus and Centaurus, centered at RA Dec , in Circinus. This " guest star" was observed by Chinese astronomers in the '' Book of Later Han'' (后汉书), and might have been recorded in Roman literature. It remained visible in the night sky for eight months. This is believed to be the first supernova for which records exist. History ''The Book of Later Han'' gives the following description: In the 2nd year of the epoch Zhongping ��平 the 10th month, on the day Guihai ��亥 ecember 7, Year 185 a ' guest star' appeared in the middle of the Sou ...

Supernova
A supernova (: supernovae or supernovas) is a powerful and luminous explosion of a star. A supernova occurs during the last stellar evolution, evolutionary stages of a massive star, or when a white dwarf is triggered into runaway nuclear fusion. The original object, called the ''progenitor'', either collapses to a neutron star or black hole, or is completely destroyed to form a diffuse nebula. The peak optical luminosity of a supernova can be comparable to that of an entire galaxy before fading over several weeks or months. The last supernova directly observed in the Milky Way was Kepler's Supernova in 1604, appearing not long after Tycho's Supernova in 1572, both of which were visible to the naked eye. The supernova remnant, remnants of more recent supernovae have been found, and observations of supernovae in other galaxies suggest they occur in the Milky Way on average about three times every century. A supernova in the Milky Way would almost certainly be observable through mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Refraction
In physics, refraction is the redirection of a wave as it passes from one transmission medium, medium to another. The redirection can be caused by the wave's change in speed or by a change in the medium. Refraction of light is the most commonly observed phenomenon, but other waves such as sound waves and Wind wave, water waves also experience refraction. How much a wave is refracted is determined by the change in wave speed and the initial direction of wave propagation relative to the direction of change in speed. Optical Prism (optics), prisms and Lens (optics), lenses use refraction to redirect light, as does the human eye. The refractive index of materials varies with the wavelength of light,R. Paschotta, article ochromatic dispersion in th, accessed on 2014-09-08 and thus the angle of the refraction also varies correspondingly. This is called dispersion (optics), dispersion and causes prism (optics), prisms and rainbows to divide white light into its constituent spectral ...

Cleomedes
Cleomedes () was a Greek astronomer who is known chiefly for his book ''On the Circular Motions of the Celestial Bodies'' (Κυκλικὴ θεωρία μετεώρων), also known as ''The Heavens'' (). Placing his work chronologically His birth and death dates are not known—historians have suggested that he wrote his work sometime between the mid-1st century BC and 400 AD. The earlier estimates rely on the fact that Cleomedes refers extensively in his writing to the work of mathematician and astronomer Posidonius of Rhodes (c. 135 – c. 51 BC), and yet seemingly not at all to the work of Ptolemy (c. 100 – c. 170 AD). (Cleomedes also refers to Aristotle (384–322 BC), Pytheas of Massalia (310–306 BC), Aratus (c. 315/310 BC – 240 BC), Eratosthenes (276–195 BC), and Hipparchus (c. 190 – c. 120 BC). These conclusions have been challenged on the grounds that Cleomedes' work was in relatively elementary astronomy, and that reference to Ptolemy would no ...

Taihang Mountains
The Taihang Mountains () are a Chinese mountain range running down the eastern edge of the Loess Plateau in Shanxi, Henan and Hebei provinces. The range extends over from north to south and has an average elevation of ; its principal peak is Mount Xiaowutai. The Taihang's eastern peak is Mount Cangyan in Hebei; Baishi Mountain forms its northern tip. Event * 185 The rebels of the Yellow Turban are defeated by the imperial army, but only two months later, the rebellion breaks out again. It spreads to the Taihang Mountains on the western border of Hebei Province. Background The Taihang Mountains were formed during the Jurassic. Brown forest and Cinnamon soils are found here. The name of Shanxi Province, meaning "west of the mountains", derives from its location west of the Taihang Mountains.

Rebellion
Rebellion is an uprising that resists and is organized against one's government. A rebel is a person who engages in a rebellion. A rebel group is a consciously coordinated group that seeks to gain political control over an entire state or a portion of a state. A rebellion is often caused by political, religious, or social grievances that originate from a perceived inequality or marginalization. ''Rebellion'' comes from Latin ''re'' and ''bellum'', and in Lockian philosophy refers to the Right of revolution, responsibility of the people to overthrow unjust government. Classification Uprisings which revolt, Resistance movement, resisting and taking direct action against an authority, law or policy, as well as organize, are rebellions. An insurrection is an uprising to change the government. If a government does not recognize rebels as belligerents, then they are insurgents and the revolt is an insurgency.
