Output (economics)Output in economics is the "quantity (or quality) of goods or services produced in a given time period, by a firm, industry, or country", whether consumed or used for further production. The concept of national output is essential in the field of macroeconomics. It is national output that makes a country rich, not large amounts of money. Output is the result of an economic process that has used inputs to produce a product or service that is available for sale or use somewhere else.
Demographic historyDemographic history is the reconstructed record of human population in the past. Given the lack of population records prior to the 1950s, there are many gaps in our record of demographic history. Historical demographers must make do with estimates, models and extrapolations. For the demographic methodology, see historical demography. World population estimates Estimating the ancestral population of anatomically modern humans, Colin McEvedy and Richard Jones chose bounds based on gorilla and chimpanzee population densities of 1/km2 and 3-4/km2, respectively, then assumed that as Homo erectus moved up the food chain, they lost an order of magnitude in density.
Duck curveThe duck curve is a graph of power production over the course of a day that shows the timing imbalance between peak demand and solar power generation. Used in utility-scale electricity generation, the term was coined in 2012 by the California Independent System Operator. In some energy markets, daily peak demand occurs after sunset, when solar power is no longer available.
Muslim worldThe terms Muslim world and Islamic world commonly refer to the Islamic community, which is also known as the Ummah. This consists of all those who adhere to the religious beliefs and laws of Islam or to societies in which Islam is practiced. In a modern geopolitical sense, these terms refer to countries in which Islam is widespread, although there are no agreed criteria for inclusion. The term Muslim-majority countries is an alternative often used for the latter sense.
History of the Middle EastThe Middle East, also known as the Near East, is home to one of the Cradles of Civilization and has seen many of the world's oldest cultures and civilizations. The region's history started from the earliest human settlements and continues through several major pre- and post-Islamic Empires to today's nation-states of the Middle East. The Sumerians became the first people to develop complex systems that were to be called "civilization" as far back as the 5th millennium BC.
Muslim BrotherhoodThe Society of the Muslim Brothers (جماعة الإخوان المسلمين ALA), better known as the Muslim Brotherhood (الإخوان المسلمون ALA), is a transnational Sunni Islamist organization founded in Egypt by Islamic scholar and schoolteacher Hassan al-Banna in 1928. Al-Banna's teachings spread far beyond Egypt, influencing today various Islamist movements from charitable organizations to political parties. Initially, as a Pan-Islamic, religious, and social movement, it preached Islam in Egypt, taught the illiterate, and set up hospitals and business enterprises.
Monopoly profitMonopoly profit is an inflated level of profit due to the monopolistic practices of an enterprise. Traditional economics state that in a competitive market, no firm can command elevated premiums for the price of goods and services as a result of sufficient competition. In contrast, insufficient competition can provide a producer with disproportionate pricing power. Withholding production to drive prices higher produces additional profit, which is called monopoly profits.
OPECThe Organization of the Petroleum Exporting Countries (OPEC, ˈoʊpɛk ) is an organization enabling the co-operation of leading oil-producing countries in order to collectively influence the global oil market and maximize profit. It was founded on 14 September 1960 in Baghdad by the first five members (Iran, Iraq, Kuwait, Saudi Arabia, and Venezuela). The 13 member countries account for an estimated 30 percent of global oil production and 80 percent of the world's proven oil reserves.
Islam in the United StatesIslam is the third largest religion in the United States (1%), behind Christianity and Judaism, equaling Buddhism and Hinduism percentage wise. A 2017 study estimated that 3.45 million Muslims were living in the United States, about 1.1 percent of the total U.S. population. In 2017, 20 states which were mostly in the South and Midwest reported Islam being the largest non-Christian religion. In 2020, the U.S. Religion Census found there to be 4.45 million Muslims in the country, making up 1.3% of the population.
