History Of Astrology
Astrological belief in relation between celestial observations and terrestrial events have influenced various aspects of human history, including world-views, language and many elements of culture. It has been argued that astrology began as a study as soon as human beings made conscious attempts to measure, record, and predict seasonal changes by reference to astronomical cycles. Early evidence of such practices appears as markings on bones and cave walls, which show that the lunar cycle was being noted as early as 25,000 years ago; the first step towards recording the Moon's influence upon tides and rivers, and towards organizing a communal calendar. With the Neolithic Revolution new needs were also being met by the increasing knowledge of constellations, whose appearances in the night-time sky change with the seasons, thus allowing the rising of particular star-groups to herald annual floods or seasonal activities. By the 3rd millennium BCE, widespread civilisations had deve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astrology
Astrology is a range of Divination, divinatory practices, recognized as pseudoscientific since the 18th century, that propose that information about human affairs and terrestrial events may be discerned by studying the apparent positions of Celestial objects in astrology, celestial objects. Different cultures have employed forms of astrology since at least the 2nd millennium BCE, these practices having originated in Calendrical calculation, calendrical systems used to predict seasonal shifts and to interpret celestial cycles as signs of divine communications. Most, if not all, cultures have attached importance to what they observed in the sky, and some—such as the Hindu astrology, Hindus, Chinese astrology, Chinese, and the Maya civilization, Maya—developed elaborate systems for predicting terrestrial events from celestial observations. Western astrology, one of the oldest astrological systems still in use, can trace its roots to 19th–17th century BCE Mesopotamia, fr ...

Calendrical Calculation
A calendrical calculation is a calculation concerning calendar dates. Calendrical calculations can be considered an area of applied mathematics. Some examples of calendrical calculations: * Converting a Julian or Gregorian calendar date to its Julian day number and vice versa . * The number of days between two dates, which is simply the difference in their Julian day numbers. * The dates of moveable holidays, like Christian Easter (the calculation is known as Computus) followed up by Ascension Thursday and Pentecost or Advent Sundays, or the Jewish Passover, for a given year. * Converting a date between different calendars. For instance, dates in the Gregorian calendar can be converted to dates in the Islamic calendar with the Kuwaiti algorithm. * Calculating the day of the week. Calendrical calculation is one of the five major Savant syndrome characteristics. Examples Numerical methods were described in the ''Journal of the Department of Mathematics,'' Open University, Milto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
First Babylonian Dynasty
The Old Babylonian Empire, or First Babylonian Empire, is dated to , and comes after the end of Sumerian power with the destruction of the Third Dynasty of Ur, and the subsequent Isin-Larsa period. The Chronology of the Ancient Near East, chronology of the first dynasty of Babylonia is debated; there is a Babylonian King List A and also a Babylonian King List B, with generally longer regnal lengths. In this chronology, the regnal years of List A are used due to their wide usage. Hardship of searching for origins of the First Dynasty The origins of the First Babylonian dynasty are hard to pinpoint because Babylon itself yields few archaeological materials intact due to a high water table. The evidence that survived throughout the years includes written records such as royal and votive inscriptions, literary texts, and lists of year-names. The minimal amount of evidence in economic and legal documents makes it difficult to illustrate the economic and social history of the First Ba ...

Babylon Relief
Babylon ( ) was an ancient city located on the lower Euphrates river in southern Mesopotamia, within modern-day Hillah, Iraq, about south of modern-day Baghdad. Babylon functioned as the main cultural and political centre of the Akkadian-speaking region of Babylonia. Its rulers established two important empires in antiquity, the 19th–16th century BC Old Babylonian Empire, and the 7th–6th century BC Neo-Babylonian Empire. Babylon was also used as a regional capital of other empires, such as the Achaemenid Empire. Babylon was one of the most important urban centres of the ancient Near East, until its decline during the Hellenistic period. Nearby ancient sites are Kish, Borsippa, Dilbat, and Kutha. The earliest known mention of Babylon as a small town appears on a clay tablet from the reign of Shar-Kali-Sharri (2217–2193 BC), of the Akkadian Empire. Babylon was merely a religious and cultural centre at this point and neither an independent state nor a large city, subject ...

Pseudoscience
Pseudoscience consists of statements, beliefs, or practices that claim to be both scientific and factual but are incompatible with the scientific method. Pseudoscience is often characterized by contradictory, exaggerated or unfalsifiable claims; reliance on confirmation bias rather than rigorous attempts at refutation; lack of openness to evaluation by other experts; absence of systematic practices when developing hypotheses; and continued adherence long after the pseudoscientific hypotheses have been experimentally discredited. It is not the same as junk science. The demarcation between science and pseudoscience has scientific, philosophical, and political implications. Philosophers debate the nature of science and the general criteria for drawing the line between scientific theories and pseudoscientific beliefs, but there is widespread agreement "that creationism, astrology, homeopathy, Kirlian photography, dowsing, ufology, ancient astronaut theory, Holocaust den ...

Heliocentrism
Heliocentrism (also known as the heliocentric model) is a superseded astronomical model in which the Earth and planets orbit around the Sun at the center of the universe. Historically, heliocentrism was opposed to geocentrism, which placed the Earth at the center. The notion that the Earth revolves around the Sun had been proposed as early as the 3rd century BC by Aristarchus of Samos, who had been influenced by a concept presented by Philolaus of Croton (c. 470 – 385 BC). In the 5th century BC the Greek philosophers Philolaus and Hicetas had the thought on different occasions that the Earth was spherical and revolving around a "mystical" central fire, and that this fire regulated the universe. In medieval Europe, however, Aristarchus' heliocentrism attracted little attention—possibly because of the loss of scientific works of the Hellenistic period. It was not until the 16th century that a mathematical model of a heliocentric system was presented by the Renaissanc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of Medicine
The history of medicine is both a study of medicine throughout history as well as a multidisciplinary field of study that seeks to explore and understand medical practices, both past and present, throughout human societies. The history of medicine is the study and documentation of the evolution of medical treatments, practices, and knowledge over time. Medical historians often draw from other humanities fields of study including economics, Outline of health sciences, health sciences, sociology, and Political science, politics to better understand the institutions, practices, people, professions, and social systems that have shaped medicine. When a period which predates or lacks written sources regarding medicine, information is instead drawn from archaeology, archaeological sources. This field tracks the evolution of human societies' approach to health, illness, and injury ranging from prehistory to the modern day, the events that shape these approaches, and their impact on pop ...

Timeline Of Meteorology
The timeline of meteorology contains events of scientific and technological advancements in the area of atmospheric sciences. The most notable advancements in observational meteorology, weather forecasting, climatology, atmospheric chemistry, and atmospheric physics are listed chronologically. Some historical weather events are included that mark time periods where advancements were made, or even that sparked policy change. Antiquity * 3000 BC – Meteorology in India can be traced back to around 3000 BC, with writings such as the Upanishads, containing discussions about the processes of cloud formation and rain and the seasonal cycles caused by the movement of the Earth around the Sun. * 600 BC – Thales may qualify as the first Greek meteorologist. He reputedly issues the first seasonal crop forecast. * 400 BC – There is some evidence that Democritus predicted changes in the weather, and that he used this ability to convince people that he could predict other future eve ...
