Century
A century is a period of 100 years or 10 decades. Centuries are numbered ordinally in English and many other languages. The word ''century'' comes from the Latin ''centum'', meaning ''one hundred''. ''Century'' is sometimes abbreviated as c. A centennial or centenary is a hundredth anniversary, or a celebration of this, typically the remembrance of an event which took place a hundred years earlier. Start and end of centuries Although a century can mean any arbitrary period of 100 years, there are two viewpoints on the nature of standard centuries. One is based on strict construction, while the other is based on popular perception. According to the strict construction, the 1st century AD, which began with AD 1, ended with AD 100, and the 2nd century with AD 200; in this model, the ''n''-th century starts with a year that follows a year with a multiple of 100 (except the first century as it began after the year 1 BC) and ends with the next coming year with a multiple o ...

First Dynasty Of Egypt
The First Dynasty of ancient Egypt (Dynasty I) covers the first series of Egyptian kings to rule over a unified Egypt. It immediately follows the unification of Upper and Lower Egypt, by Menes, or Narmer, and marks the beginning of the Early Dynastic Period, when power was centered at Thinis. The date of this period is subject to scholarly debate about the Egyptian chronology. It falls within the early Bronze Age and is variously estimated to have begun anywhere between the 34th and the 30th centuriesBC. In a 2013 study based on radiocarbon dates, the accession of Hor-Aha, the second king of the First Dynasty, was placed between 3111 and 3045 BC with 68% confidence, and between 3218 and 3035 with 95% confidence. The same study placed the accession of Den, the sixth king of the dynasty, between 2928 and 2911 BC with 68% confidence, although a 2023 radiocarbon analysis placed Den's accession potentially earlier, between 3011 and 2921, within a broader window of 3104 to 2913.

List Of Oldest Trees
This is a list of the oldest-known trees, as reported in reliable sources. Definitions of what constitutes an individual tree vary. In addition, tree ages are derived from a variety of sources, including documented "tree-ring" ( dendrochronological) count core samples, and from estimates. For these reasons, this article presents three lists of "oldest trees," each using varying criteria. There are three tables of trees, which are listed by age and species. The first table includes trees for which a minimum age has been directly determined, either through counting or cross-referencing tree rings or through radiocarbon dating. Many of these trees may be even older than their listed ages, but the oldest wood in the tree has rotted away. For some old trees, so much of the center is missing that their age cannot be directly determined. Instead, estimates are made based on the tree's size and presumed growth rate. The second table includes trees with these estimated ages. The last table ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Methuselah (pine Tree)
Methuselah is a -year-old Pinus longaeva, Great Basin bristlecone pine (''Pinus longaeva'') tree growing high in the White Mountains (California), White Mountains of Inyo County, California, Inyo County in eastern California. It is recognized as the non-Vegetative reproduction, clonal tree with the greatest confirmed age in the world. Its old age is a result of harsh weather and a lack of nutrients, which slow down the decaying process. The tree's name refers to the biblical patriarch Methuselah, who is said to have reached 969 years of age before his death, thus becoming synonymous with longevity or old age in many European languages including English. Geography Methuselah is located between above sea level in the "Methuselah Grove" in the Ancient Bristlecone Pine Forest within the Inyo National Forest. The United States Forest Service does not disclose its exact location, although the tree's location is now widely known and available on the internet following a high-profile lea ...

Three Sovereigns And Five Emperors
According to Chinese mythology and traditional Chinese historiography, the Three Sovereigns and Five Emperors () were a series of sage Chinese emperors, and the first Emperors of China. Today, they are considered culture heroes, but they were widely worshipped as divine "ancestral spirits" in ancient times. According to received history, the period they existed in preceded the Xia dynasty, although they were thought to exist in later periods to an extent in incorporeal forms that aided the Chinese people, especially with the stories of Nüwa existing as a spirit in the Shang dynasty and Shennong being identified as the godly form of Hou Ji and a founder of the Zhou dynasty. In myth, the Three Sovereigns were demigods who used their abilities to help create mankind and impart to them essential skills and knowledge. The Five Emperors were exemplary sages who possessed great moral character, and were from a golden age when "communications between the human order and the divine ...

Intercalation (timekeeping)
Intercalation or embolism in timekeeping is the insertion of a leap day, week, or month into some calendar years to make the calendar follow the seasons or moon phases. Lunisolar calendars may require intercalations of days or months. Solar calendars The solar or tropical year does not have a whole number of days (it is about 365.24 days), but a calendar year must have a whole number of days. The most common way to reconcile the two is to vary the number of days in the calendar year. In solar calendars, this is done by adding an extra day ("leap day" or "intercalary day") to a common year of 365 days, about once every four years, creating a leap year that has 366 days ( Julian, Gregorian and Indian national calendars). The Decree of Canopus, issued by the pharaoh Ptolemy III Euergetes of Ancient Egypt in 239 BC, decreed a solar leap day system; an Egyptian leap year was not adopted until 25 BC, when the Roman Emperor Augustus instituted a reformed Alexandrian cal ...

365-day Calendar
A 365-day calendar consists of exactly 365 days per year (in common years), and is primarily used in computer models and as an assumption in every-day calculations. For example, a calculation of a daily rate may use an annual total divided by exactly 365. Interest rates in some banks are calculated using a 365-day calendar. Other 365-day calendars Some Mesoamerican calendars used a 365-day year with no leap year, resulting in a gradual shift of the seasons relative to the calendar. This includes the Maya Haab' and the Aztec Xiuhpohualli calendars. Some versions of the Zoroastrian calendar also use a fixed length of 365 days with no rule for leap days, despite potential leap year rules being acknowledged by the 9th century at the latest. In particular, of the versions still in use today the Qadimi version does not have any form of leap rule; the Shahanshahi version had one leap month added in the 12th century but no leap years since, while the Fasli version (introduced in the 2 ...

Hồng Bàng Dynasty
The Hồng Bàng period (), also called the Hồng Bàng dynasty,Pelley, p. 151 was a legendary ancient period in Vietnamese historiography, spanning from the beginning of the rule of Kinh Dương Vương over the kingdom of Văn Lang (initially called Xích Quỷ) in 2879 BC until the conquest of the state by An Dương Vương in 258 BC. Vietnamese history textbooks claim that this state was established in the 7th century BC on the basis of the Dong Son culture. The 15th-century Vietnamese chronicle ''Đại Việt sử ký toàn thư'' (''Đại Việt, The Complete History'') claimed that the period began with Kinh Dương Vương as the first Hùng king ( or ''Vua Hùng''), a title used in many modern discussions of the ancient Vietnamese rulers of this period. The Hùng king was the absolute monarch of the country and, at least in theory, wielded complete control of the land and its resources. The ''Đại Việt sử ký toàn thư'' also recorded that the nation's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kinh Dương Vương
Kinh Dương Vương (chữ Hán: 涇陽王; "King of Kinh Dương") is a legendary ancient Vietnamese figure, mentioned in the 15th-century work ''Đại Việt sử ký toàn thư'' by having unified all the tribes within his territory into one state, and as the founder of the Hồng Bàng dynasty. He is considered the first sovereign of the Vietnamese people. According to the 15th-century ''Đại Việt sử ký toàn thư'', he ruled over the state of Xích Quỷ (赤鬼國) starting in 2879 BC. Kinh Dương Vương's father was Đế Minh (帝明, "Emperor Ming" of Chinese and Vietnamese mythology), a descendant of Shennong (Thần Nông). Kinh Dương Vương is believed to having married Thần Long, the daughter of Động Đình Quân (洞庭君; "Lord of Dongting") and given birth to Lạc Long Quân. Today Kinh Dương Vương features with other ancient figures such as Thánh Gióng, Âu Cơ, Sơn Tinh and Thủy Tinh are a part of the elementary school texts. ...

Prometheus (tree)
Prometheus (recorded as WPN-114) was the world's oldest known non- clonal organism, a Great Basin bristlecone pine (''Pinus longaeva'') tree growing near the tree line on Wheeler Peak in eastern Nevada, United States. The tree, which was at least 4,862 years old and possibly more than 5,000, was cut down in 1964 by a graduate student and United States Forest Service personnel for research purposes. Those involved did not know of its world-record age before the cutting, and the circumstances and decision-making process remains controversial. The tree's name refers to the mythological figure Prometheus, who stole fire from the gods and gave it to man. The designation WPN-114 was given by the original researcher, Donald Rusk Currey, and means it was the 114th tree he sampled in his research in Nevada's White Pine County. Discovery and age Prometheus (WPN-114) was a living member of a population of bristlecone pine trees near the tree line on the lateral moraine of a former gl ...
