20th Century In Technology
The history of technology is the history of the invention of tools and techniques and is one of the categories of world history. Technology can refer to methods ranging from as simple as stone tools to the complex genetic engineering and information technology that has emerged since the 1980s. The term technology comes from the Greek word ''techne'', meaning art and craft, and the word logos, meaning word and speech. It was first used to describe applied arts, but it is now used to describe advancements and changes which affect the environment around us. New knowledge has also enabled people to create new things, and conversely, many scientific endeavors are made possible by technologies which assist humans in traveling to places they could not previously reach, and by scientific instruments by which we study nature in more detail than our natural senses allow. Since much of technology is applied science, technical history is connected to the history of science. Since techn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ur Chariot
Ur (; Sumerian language, Sumerian: , , or ''Urim''; akk, 𒋀𒀕𒆠 ''Uru''; ar, أُوْر, ʾūr; he, אוּר, ʾūr) was an important Sumerian city-state in ancient Mesopotamia, located at the site of modern Tell el-Muqayyar ( ar, تل ٱلْمُقَيَّر) in south Iraq's Dhi Qar Governorate. Although Ur was once a coastal city near the mouth of the Euphrates on the Persian Gulf, the coastline has shifted and the city is now well inland, on the south bank of the Euphrates, from Nasiriyah in modern-day Iraq. The city dates from the Ubaid period circa 3800 BC, and is recorded in recorded history, written history as a city-state from the 26th century BC, its first recorded king being Mesannepada. The city's patron deity was Sin (mythology), Nanna (in Akkadian language, Akkadian, Sin (mythology), Sin), the Sumerian and Akkadian Empire, Akkadian Lunar deity, moon god, and the name of the city is in origin derived from the god's name, UNUGKI, literally "the abode ( ...

Economic Growth
Economic growth can be defined as the increase or improvement in the inflation-adjusted market value of the goods and services produced by an economy in a financial year. Statisticians conventionally measure such growth as the percent rate of increase in the real gross domestic product, or real GDP. Growth is usually calculated in real terms – i.e., inflation-adjusted terms – to eliminate the distorting effect of inflation on the prices of goods produced. Measurement of economic growth uses national income accounting. Since economic growth is measured as the annual percent change of gross domestic product (GDP), it has all the advantages and drawbacks of that measure. The economic growth-rates of countries are commonly compared using the ratio of the GDP to population (per-capita income). The "rate of economic growth" refers to the geometric annual rate of growth in GDP between the first and the last year over a period of time. This growth rate represents the trend in ...

Culture
Culture () is an umbrella term which encompasses the social behavior, institutions, and norms found in human societies, as well as the knowledge, beliefs, arts, laws, customs, capabilities, and habits of the individuals in these groups.Tylor, Edward. (1871). Primitive Culture. Vol 1. New York: J.P. Putnam's Son Culture is often originated from or attributed to a specific region or location. Humans acquire culture through the learning processes of enculturation and socialization, which is shown by the diversity of cultures across societies. A cultural norm codifies acceptable conduct in society; it serves as a guideline for behavior, dress, language, and demeanor in a situation, which serves as a template for expectations in a social group. Accepting only a monoculture in a social group can bear risks, just as a single species can wither in the face of environmental change, for lack of functional responses to the change. Thus in military culture, valor is counted a typica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Energy
In physics, energy (from Ancient Greek: ἐνέργεια, ''enérgeia'', “activity”) is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light. Energy is a conserved quantity—the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The unit of measurement for energy in the International System of Units (SI) is the joule (J). Common forms of energy include the kinetic energy of a moving object, the potential energy stored by an object (for instance due to its position in a field), the elastic energy stored in a solid object, chemical energy associated with chemical reactions, the radiant energy carried by electromagnetic radiation, and the internal energy contained within a thermodynamic system. All living organisms constantly take in and release energy. Due to mass–energy equivalence, any object that has mass whe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Civilization
A civilization (or civilisation) is any complex society characterized by the development of a state, social stratification, urbanization, and symbolic systems of communication beyond natural spoken language (namely, a writing system). Civilizations are intimately associated with additional characteristics such as centralization, the domestication of plant and animal species (including humans), specialization of labour, culturally-ingrained ideologies of progress, monumental architecture, taxation, societal dependence upon farming, and expansionism. Historically, a civilization has often been understood as a larger and "more advanced" culture, in implied contrast to smaller, supposedly less advanced cultures. In this broad sense, a civilization contrasts with non-centralized tribal societies, including the cultures of nomadic pastoralists, Neolithic societies or hunter-gatherers; however, sometimes it also contrasts with the cultures found within civilizations themselv ...

Primitive Culture
''Primitive Culture'' is an 1871 book by Edward Burnett Tylor. In his book, Tylor debates the relationship between "primitive" societies, and "civilized" societies, a key theme in 19th century anthropological literature. Evolutionism Tylor's work can be connected to theories present in 19th century literature including Lewis Henry Morgan's "ethnical periods". Among 19th century anthropologists, many saw what now may be called "tribal" states and societies, as lacking in form, progress, and development. Both Tylor and Morgan aligned somewhat with this viewpoint, Morgan believing in stages in order from savagery, barbarism, to civilization, and Tylor concluding that savagery is the lower stage of civilization. Tylor; unlike Morgan however; believed in " Prichardian Ethnological Monogenism", something he learnt in turn during his travels in Mexico from Henry Christy (1810-1865).Observing "Man" in Situ: Edward Burnett Taylor's Travels Through Mexico, Efram Sera-Shriar, December 20 ...

Technological Progress
Technology is the application of knowledge to reach practical goals in a specifiable and reproducible way. The word ''technology'' may also mean the product of such an endeavor. The use of technology is widely prevalent in medicine, science, industry, communication, transportation, and daily life. Technologies include physical objects like utensils or machines and intangible tools such as software. Many technological advancements have led to societal changes. The earliest known technology is the stone tool, used in the prehistoric era, followed by fire use, which contributed to the growth of the human brain and the development of language in the Ice Age. The invention of the wheel in the Bronze Age enabled wider travel and the creation of more complex machines. Recent technological developments, including the printing press, the telephone, and the Internet have lowered communication barriers and ushered in the knowledge economy. While technology contributes to economic deve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cultural Evolution
Cultural evolution is an evolutionary theory of social change. It follows from the definition of culture as "information capable of affecting individuals' behavior that they acquire from other members of their species through teaching, imitation and other forms of social transmission". Cultural evolution is the change of this information over time. Cultural evolution, historically also known as sociocultural evolution, was originally developed in the 19th century by anthropologists stemming from Charles Darwin's research on evolution. Today, cultural evolution has become the basis for a growing field of scientific research in the social sciences, including anthropology, economics, psychology and organizational studies. Previously, it was believed that social change resulted from biological adaptations, but anthropologists now commonly accept that social changes arise in consequence of a combination of social, evolutionary and biological influences. There have been a number of diff ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sociocultural Evolution
Sociocultural evolution, sociocultural evolutionism or social evolution are theories of sociobiology and cultural evolution that describe how societies and culture change over time. Whereas sociocultural development traces processes that tend to increase the complexity of a society or culture, sociocultural evolution also considers process that can lead to decreases in complexity ( degeneration) or that can produce variation or proliferation without any seemingly significant changes in complexity (cladogenesis). Sociocultural evolution is "the process by which structural reorganization is affected through time, eventually producing a form or structure which is qualitatively different from the ancestral form". Most of the 19th-century and some 20th-century approaches to socioculture aimed to provide models for the evolution of humankind as a whole, arguing that different societies have reached different stages of social development.
