Maya civilization

This article is about the pre-Columbian Maya civilization. For a discussion of the modern Maya, see Maya peoples. For other meanings of the word Maya, seeMaya.
 The Maya is a Mesoamerican civilization, noted for Maya script, the only known fully developed writing system of the pre-Columbian Americas, as well as for its art, architecture, and mathematical and astronomical systems. Initially established during the Pre-Classic period (c. 2000 BC to AD 250), according to the Mesoamerican chronology, many Maya cities reached their highest state of development during the Classic period (c. AD 250 to 900), and continued throughout the Post-Classic period until the arrival of the Spanish.
The Maya civilization shares many features with other Mesoamerican civilizations due to the high degree of interaction andcultural diffusion that characterized the region. Advances such as writing, epigraphy, and the calendar did not originate with the Maya; however, their civilization fully developed them. Maya influence can be detected in Honduras, Belize, Guatemala, and western El Salvador to as far away as central Mexico, more than 1,000 km (620 mi) from the central Maya area. The many outside influences found in Maya art and architecture are thought to have resulted from trade and cultural exchange rather than direct external conquest...
The Maya peoples survived the Classic period collapse and the arrival of the Spanish conquistadores and sixteenth-centurySpanish colonization of the Americas. Today, the Maya and their descendants form sizable populations throughout the Maya area; they maintain a distinctive set of traditions and beliefs resulting from the merger of pre-Columbian and post-Conquest ideas and cultures. Millions of people speak Mayan languages today. In 2005 the Rabinal Achí, a play written in the Achi language, was declared a Masterpiece of the Oral and Intangible Heritage of Humanity by UNESCO.

Geographical extent

The Maya civilization extended throughout the present-day southern Mexican states of Chiapas, Tabasco, and the Yucatán Peninsula states of Quintana Roo, Campeche and Yucatán. The Maya area also extended throughout the northern Central American region, including the present-day nations of Guatemala, Belize, western Honduras and extreme northern El Salvador.
The Maya area is generally divided into three loosely defined zones: the southern Pacific lowlands, the highlands, and the northern lowlands. The Maya highlands include all of elevated terrain in Guatemala and the Chiapas highlands of Mexico. The southern lowlands lie just south of the highlands, and incorporate a part of the Mexican state of Chiapas, the south coast of Guatemala, Belize and northern El Salvador. The northern lowlands cover all of the Yucatán Peninsula, including the Mexican states of Yucatán, Campeche and Quintana Roo, the Petén Department of Guatemala, and all of Belize. Parts of the Mexican states of Tabasco and Chiapas are also included in the northern lowlands.

Preclassic period

Main article: Preclassic Maya
Scholars continue to discuss when this era of Maya civilization began. Discoveries of Maya occupation at Cuello, Belize have been carbon dated to around 2600BCE. The people built monumental structures. The Maya calendar, which is based on the so-called Mesoamerican Long Count calendar, begins on a date equivalent to 11 August 3114 BC.
The most widely accepted view, as of 2010, is that the first clearly Maya settlements were established around 1800 BCE in the Soconusco region of the Pacific Coast. This period, known as the Early Preclassic , was characterized by sedentary communities and the introduction of pottery and fired clayfigurines .
Important sites in the southern Maya lowlands include Nakbe, El Mirador, Cival, and San Bartolo. In the Guatemalan Highlands, Kaminaljuyu emerged around 800 BC. For many centuries it controlled the jade and obsidian sources for the Petén and Pacific Lowlands. The important early sites of Izapa, Takalik Abaj, and Chocoláat around 600 BCE were the main producers of Cacao. Mid-sized Maya communities also began to develop in the northern Maya lowlands during the Middle and Late Preclassic, though these lacked the size, scale, and influence of the large centers of the southern lowlands. Two important Preclassic northern sites includeKomchen and Dzibilchaltun. The first written inscription in Maya hieroglyphics also dates to this period (c. 250 BCE).
Scholars disagree about the boundaries that define the physical and cultural extent of the early Maya and neighboring Preclassic Mesoamerican civilizations, such as the Olmec culture of the Tabasco lowlands and the Mixe–Zoque- and Zapotec-speaking peoples of Chiapas and southern Oaxaca, respectively. Many of the earliest significant inscriptions and buildings appeared in this overlapping zone, and evidence suggests that these cultures and the formative Maya influenced one another. Takalik Abaj, in the Pacific slopes of Guatemala, is the only site where Olmec features have been clearly succeeded by Mayan ones.
Around 100 AD, a widespread decline and abandonment of Maya cities occurred – called the Preclassic Collapse. This marked the end of the Preclassic era.

Classic period



The Classic period (c. AD 250–900) was one of the peak of large-scale construction and urbanism, the recording of monumental inscriptions, and significant intellectual and artistic development, particularly in the southern lowland regions.
The people developed an agriculturally intensive, city-centered civilization consisting of numerous independent city-states – some subservient to others This includes the well-known cities of Caracol, Tikal, Palenque, Copán, Xunantunich andCalakmul, but also the lesser known Lamanai, Dos Pilas, Cahal Pech, Uaxactun, Altun Ha, and Bonampak, among others. The Early Classic settlement distribution in the northern Maya lowlands is not as clearly known as the southern zone, but does include a number of population centers, such as Oxkintok, Chunchucmil, and the early occupation of Uxmal.
During this period the Maya population numbered in the millions. They created a multitude of kingdoms and small empires, built monumental palaces and temples, engaged in highly developed ceremonies, and developed an elaborate hieroglyphicwriting system.
The social basis of this exuberant civilization was a large political and economic intersocietal network (world system) extending throughout the Maya region and beyond to the wider Mesoamerican world. The political, economic, and culturally dominant ‘core’ Maya units of the Classic Maya world system were located in the central lowlands, while its corresponding dependent or ‘peripheral’ Maya units were found along the margins of the southern highland and northern lowland areas. But as in all world systems, the Maya core centers shifted through time, starting out during Preclassic times in the southern highlands, moving to the central lowlands during the Classic period, and finally shifting to the northern peninsula during the Postclassic period. In this Maya world system, the semi-peripheral (mediational) units generally took the form of trade and commercial centers..


The most notable monuments are the stepped pyramids they built in their religious centers and the accompanying palaces of their rulers. The palace at Cancuén is the largest in the Maya area, but the site has no pyramids. Other important archaeological remains include the carved stone slabs usually called stelae (the Maya called them tetun, or "tree-stones"), which depict rulers along with hieroglyphic texts describing their genealogy, military victories, and other accomplishments.[12]
The Maya civilization participated in long distance trade with many of the other Mesoamerican cultures, including Teotihuacan, the Zapotec, and other groups in central and gulf-coast Mexico. In addition, they had trade and exchanges with more distant, non-Mesoamerican groups, for example the Taínos of the Caribbean islands. Archeologists have found gold from Panama in the Sacred Cenote of Chichen Itza.Important trade goods included cacao, salt, seashells, jade, andobsidian...

Barbary lion












Museum specimens of male Barbary lion were described as having very dark and long-haired manes that extended over the shoulder and to the belly. Head-to-tail length of stuffed males varies from 2.35 to 2.8 m (7 ft 9 in to 9 ft 2 in), and females measure around 2.5 m (8 ft 2 in). A 19th century hunter described a large male allegedly measuring 3.25 m (10.7 ft) including a 75 cm (30 in) long tail. In some historic accounts the weight of wild males was indicated as very heavy and reaching 270 to 300 kilograms (600 to 660 lb). But the accuracy of the measurements may be questionable, and the sample size of captive Barbary lions were too small to conclude they were the biggest lion subspecies.
Before it became possible to investigate the genetic diversity of lion populations, the colour and size of lion manes was thought to be a sufficiently distinct morphological characteristic to accord a subspecific status to populations. Results of a long-term study of lions in the Serengeti National Park indicate that various factors such as ambient temperature, nutrition and level of testosterone influence the colour and size of lion manes. Sub-Saharan lions kept in a cool environment of European and North American zoos usually develop bigger manes than their wild counterparts. Barbary lions may have developed long-haired manes because of the temperatures in the Atlas Mountains that are much lower than in other African regions, particularly in winter. Therefore, the size of manes is not regarded as appropriate evidence for identifying Barbary lion ancestry. Results of mitochondrial DNA research published in 2006 support the genetic distinctness of Barbary lions in a unique haplotype found in museum specimens that are believed to be of Barbary lion descent. The presence of this haplotype is considered a reliable ..molecular marker for the identification of Barbary lions surviving in captivit

Albert Einstein


Albert Einstein was born at Ulm, in Württemberg, Germany, on March 14, 1879. Six weeks later the family moved to Munich, where he later on began his schooling at the Luitpold Gymnasium. Later, they moved to Italy and Albert continued his education at Aarau, Switzerland and in 1896 he entered the Swiss Federal Polytechnic School in Zurich to be trained as a teacher in physics and mathematics. In 1901, the year he gained his diploma, he acquired Swiss citizenship and, as he was unable to find a teaching post, he accepted a position as technical assistant in the Swiss Patent Office. In 1905 he obtained his doctor's degree.


During his stay at the Patent Office, and in his spare time, he produced much of his remarkable work and in 1908 he was appointed Privatdozent in Berne. In 1909 he became Professor Extraordinary at Zurich, in 1911 Professor of Theoretical Physics at Prague, returning to Zurich in the following year to fill a similar post. In 1914 he was appointed Director of the Kaiser Wilhelm Physical Institute and Professor in the University of Berlin. He became a German citizen in 1914 and remained in Berlin until 1933 when he renounced his citizenship for political reasons and emigrated to America to take the position of Professor of Theoretical Physics at Princeton*. He became a United States citizen in 1940 and retired from his post in 1945.



After World War II, Einstein was a leading figure in the World Government Movement, he was offered the Presidency of the State of Israel, which he declined, and he collaborated with Dr. Chaim Weizmann in establishing the Hebrew University of Jerusalem.



Einstein always appeared to have a clear view of the problems of physics and the determination to solve them. He had a strategy of his own and was able to visualize the main stages on the way to his goal. He regarded his major achievements as mere stepping-stones for the next advance.



At the start of his scientific work, Einstein realized the inadequacies of Newtonian mechanics and his special theory of relativity stemmed from an attempt to reconcile the laws of mechanics with the laws of the electromagnetic field. He dealt with classical problems of statistical mechanics and problems in which they were merged with quantum theory: this led to an explanation of the Brownian movement of molecules. He investigated the thermal properties of light with a low radiation density and his observations laid the foundation of the photon theory of light.



In his early days in Berlin, Einstein postulated that the correct interpretation of the special theory of relativity must also furnish a theory of gravitation and in 1916 he published his paper on the general theory of relativity. During this time he also contributed to the problems of the theory of radiation and statistical mechanics.



In the 1920's, Einstein embarked on the construction of unified field theories, although he continued to work on the probabilistic interpretation of quantum theory, and he persevered with this work in America. He contributed to statistical mechanics by his development of the quantum theory of a monatomic gas and he has also accomplished valuable work in connection with atomic transition probabilities and relativistic cosmology.



After his retirement he continued to work towards the unification of the basic concepts of physics, taking the opposite approach, geometrisation, to the majority of physicists.



Einstein's researches are, of course, well chronicled and his more important works include Special Theory of Relativity (1905), Relativity (English translations, 1920 and 1950), General Theory of Relativity (1916), Investigations on Theory of Brownian Movement (1926), and The Evolution of Physics (1938). Among his non-scientific works, About Zionism (1930), Why War? (1933), My Philosophy(1934), and Out of My Later Years (1950) are perhaps the most important.



Albert Einstein received honorary doctorate degrees in science, medicine and philosophy from many European and American universities. During the 1920's he lectured in Europe, America and the Far East, and he was awarded Fellowships or Memberships of all the leading scientific academies throughout the world. He gained numerous awards in recognition of his work, including the Copley Medal of the Royal Society of London in 1925, and the Franklin Medal of the Franklin Institute in 1935.



Einstein's gifts inevitably resulted in his dwelling much in intellectual solitude and, for relaxation, music played an important part in his life. He married Mileva Maric in 1903 and they had a daughter and two sons; their marriage was dissolved in 1919 and in the same year he married his cousin, Elsa Löwenthal, who died in 1936. He died on April 18, 1955 at Princeton, New Jersey.
