Stela Of The Cactus Bearer
The stela of the cactus bearer is a monolith or stele of a single piece of granite, belonging to the Chavín culture of ancient Peru, which remains in its original location on the northwest side of the circular plaza at the archaeological site known as the ceremonial center of Chavín de Huántar in the Ancash region of Peru. It was discovered during the 1972 excavation season by Peruvian archaeologist Luis Guillermo Lumbreras. In 2001, a fragment of another stela was found in the circular plaza showing an exact mirror image of the stela of the cactus bearer. This fragment suggests that there were four stelae with this same representation: two in the northeast quadrant and two in the southeast quadrant, all facing the stairway leading to the gallery of the Lanzón de Chavín. The importance of this stela lies mainly in the fact that it is the clearest iconographic finding regarding the ancestral and ritual use of the '' Echinopsis pachanoi'' cactus in the Andes.

Chavín De Huántar
Chavín de Huántar is an archaeological site in Peru, containing ruins and artifacts constructed as early as 1200 BC, and occupied until around 400–500 BC by the Chavín, a major pre-Inca culture. The site is located in the Ancash Region, north of Lima, at an elevation of , east of the Cordillera Blanca at the start of the Conchucos Valley. Chavín de Huántar has been designated as a UNESCO World Heritage Site. Some of the Chavín relics from this archaeological site are on display in the Museo de la Nación in Lima and the Museo Nacional de Chavín in Chavín itself. Occupation at Chavín de Huántar has been carbon-dated to at least 3000 BC, with ceremonial center activity occurring primarily toward the end of the second millennium, and through the middle of the first millennium BC. While the fairly large population was based on an agricultural economy, the city's location at the headwaters of the Marañón River, between the coast and the jungle, made it an ideal loca ...

Andes
The Andes, Andes Mountains or Andean Mountains (; ) are the longest continental mountain range in the world, forming a continuous highland along the western edge of South America. The range is long, wide (widest between 18°S – 20°S latitude), and has an average height of about . The Andes extend from north to south through seven South American countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, and Argentina. Along their length, the Andes are split into several ranges, separated by intermediate depressions. The Andes are the location of several high plateaus—some of which host major cities such as Quito, Bogotá, Cali, Arequipa, Medellín, Bucaramanga, Sucre, Mérida, El Alto and La Paz. The Altiplano plateau is the world's second-highest after the Tibetan plateau. These ranges are in turn grouped into three major divisions based on climate: the Tropical Andes, the Dry Andes, and the Wet Andes. The Andes Mountains are the highest m ...

Accelerator Mass Spectrometry
Accelerator mass spectrometry (AMS) is a form of mass spectrometry that accelerates ions to extraordinarily high kinetic energies before mass analysis. The special strength of AMS among the mass spectrometric methods is its power to separate a rare isotope from an abundant neighboring mass ("abundance sensitivity", e.g. 14C from 12C). The method suppresses molecular isobars completely and in many cases can separate atomic isobars (e.g. 14N from 14C) also. This makes possible the detection of naturally occurring, long-lived radio-isotopes such as 10Be, 36Cl, 26Al and 14C. Their typical isotopic abundance ranges from 10−12 to 10−18. AMS can outperform the competing technique of decay counting for all isotopes where the half-life is long enough. Other advantages of AMS include its short measuring time as well as its ability to detect atoms in extremely small samples. The method Generally, negative ions are created (atoms are ionized) in an ion source. In for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yale University
Yale University is a private research university in New Haven, Connecticut. Established in 1701 as the Collegiate School, it is the third-oldest institution of higher education in the United States and among the most prestigious in the world. It is a member of the Ivy League. Chartered by the Connecticut Colony, the Collegiate School was established in 1701 by clergy to educate Congregational ministers before moving to New Haven in 1716. Originally restricted to theology and sacred languages, the curriculum began to incorporate humanities and sciences by the time of the American Revolution. In the 19th century, the college expanded into graduate and professional instruction, awarding the first PhD in the United States in 1861 and organizing as a university in 1887. Yale's faculty and student populations grew after 1890 with rapid expansion of the physical campus and scientific research. Yale is organized into fourteen constituent schools: the original undergraduate col ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Richard L
Richard is a male given name. It originates, via Old French, from Old Frankish and is a compound of the words descending from Proto-Germanic ''*rīk-'' 'ruler, leader, king' and ''*hardu-'' 'strong, brave, hardy', and it therefore means 'strong in rule'. Nicknames include "Richie", "Dick", "Dickon", " Dickie", "Rich", "Rick", "Rico", "Ricky", and more. Richard is a common English, German and French male name. It's also used in many more languages, particularly Germanic, such as Norwegian, Danish, Swedish, Icelandic, and Dutch, as well as other languages including Irish, Scottish, Welsh and Finnish. Richard is cognate with variants of the name in other European languages, such as the Swedish "Rickard", the Catalan "Ricard" and the Italian "Riccardo", among others (see comprehensive variant list below). People named Richard Multiple people with the same name * Richard Andersen (other) * Richard Anderson (other) * Richard Cartwright (other) * Ri ...

Stanford University
Stanford University, officially Leland Stanford Junior University, is a private research university in Stanford, California. The campus occupies , among the largest in the United States, and enrolls over 17,000 students. Stanford is considered among the most prestigious universities in the world. Stanford was founded in 1885 by Leland and Jane Stanford in memory of their only child, Leland Stanford Jr., who had died of typhoid fever at age 15 the previous year. Leland Stanford was a U.S. senator and former governor of California who made his fortune as a railroad tycoon. The school admitted its first students on October 1, 1891, as a coeducational and non-denominational institution. Stanford University struggled financially after the death of Leland Stanford in 1893 and again after much of the campus was damaged by the 1906 San Francisco earthquake. Following World War II, provost of Stanford Frederick Terman inspired and supported faculty and graduates' entrepreneu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Archaeologist
Archaeology or archeology is the scientific study of human activity through the recovery and analysis of material culture. The archaeological record consists of artifacts, architecture, biofacts or ecofacts, sites, and cultural landscapes. Archaeology can be considered both a social science and a branch of the humanities. It is usually considered an independent academic discipline, but may also be classified as part of anthropology (in North America – the four-field approach), history or geography. Archaeologists study human prehistory and history, from the development of the first stone tools at Lomekwi in East Africa 3.3 million years ago up until recent decades. Archaeology is distinct from palaeontology, which is the study of fossil remains. Archaeology is particularly important for learning about prehistoric societies, for which, by definition, there are no written records. Prehistory includes over 99% of the human past, from the Paleolithic until the adve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Headstone
A headstone, tombstone, or gravestone is a stele or marker, usually stone, that is placed over a grave. It is traditional for burials in the Christian, Jewish, and Muslim religions, among others. In most cases, it has the deceased's name, date of birth, and date of death inscribed on it, along with a personal message, or prayer, but may contain pieces of funerary art, especially details in stone relief. In many parts of Europe, insetting a photograph of the deceased in a frame is very common. Use The stele (plural stelae), as it is called in an archaeological context, is one of the oldest forms of funerary art. Originally, a tombstone was the stone lid of a stone coffin, or the coffin itself, and a gravestone was the stone slab that was laid over a grave. Now, all three terms are also used for markers placed at the head of the grave. Some graves in the 18th century also contained footstones to demarcate the foot end of the grave. This sometimes developed into full kerb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Procession
A procession is an organized body of people walking in a formal or ceremonial manner. History Processions have in all peoples and at all times been a natural form of public celebration, as forming an orderly and impressive ceremony. Religious and triumphal processions are abundantly illustrated by ancient monuments, e.g. the religious processions of Egypt, those illustrated by the rock-carvings of Boghaz-Keui, the many representations of processions in Greek art, culminating in the great Panathenaic procession of the Parthenon Frieze, and Roman triumphal reliefs, such as those of the arch of Titus. Greco-Roman practice Processions played a prominent part in the great festivals of Greece, where they were always religious in character. The games were either opened or accompanied by more or less elaborate processions and sacrifices, while processions from the earliest times formed part of the worship of the old nature gods, as those connected with the cult of Dionysus and the Ph ...

Anthropomorphism
Anthropomorphism is the attribution of human traits, emotions, or intentions to non-human entities. It is considered to be an innate tendency of human psychology. Personification is the related attribution of human form and characteristics to abstract concepts such as nations, emotions, and natural forces, such as seasons and weather. Both have ancient roots as storytelling and artistic devices, and most cultures have traditional fables with anthropomorphized animals as characters. People have also routinely attributed human emotions and behavioral traits to wild as well as domesticated animals. Etymology Anthropomorphism and anthropomorphization derive from the verb form ''anthropomorphize'', itself derived from the Greek ''ánthrōpos'' (, "human") and ''morphē'' (, "form"). It is first attested in 1753, originally in reference to the heresy of applying a human form to the Christian God.''Oxford English Dictionary'', 1st ed. "anthropomorphism, ''n.''"

Hemicycle
In legislatures, a hemicycle is a semicircular, or horseshoe-shaped, debating chamber (''plenary chamber''), where deputies (members) sit to discuss and pass legislation. Although originally of Ancient Greek roots, the term and modern design derive from French politics and practice. Usage The circular shape is designed to encourage consensus among political parties rather than confrontation, such as in the Palace of Westminster, where the government and opposition parties face each other on opposing sets of benches. The design is used in most European countries (and hence was adopted by the European Parliament) and the United States. The United Kingdom, which is the originator of the Westminster system, does not use a hemicycle. However, two of the three devolved legislatures, the Scottish Parliament and Senedd (Welsh Parliament), do use hemicycles; the Northern Ireland Assembly does not use a hemicycle format, but instead uses a "horseshoe" format, a hybrid of both the hemi ...

Quadrant (plane Geometry)
The axes of a two-dimensional Cartesian system divide the plane into four infinite regions, called quadrants, each bounded by two half-axes. These are often numbered from 1st to 4th and denoted by Roman numerals: I (where the signs of the (''x''; ''y'') coordinates are I (+; +), II (−; +), III (−; −), and IV (+; −). When the axes are drawn according to the mathematical custom, the numbering goes counter-clockwise starting from the upper right ("northeast") quadrant. Mnemonic In the above graphic, the words in quotation marks are a mnemonic for remembering which three trigonometric functions (sine, cosine and tangent) are positive in each quadrant. The expression reads "All Science Teachers Crazy" and proceeding counterclockwise from the upper right quadrant, we see that "All" functions are positive in quadrant I, "Science" (for sine) is positive in quadrant II, "Teachers" (for tangent) is positive in quadrant III, and "Crazy" (for cosine) is p ...
