IterationIteration is the repetition of a process in order to generate a (possibly unbounded) sequence of outcomes. Each repetition of the process is a single iteration, and the outcome of each iteration is then the starting point of the next iteration. In mathematics and computer science, iteration (along with the related technique of recursion) is a standard element of algorithms. In mathematics, iteration may refer to the process of iterating a function, i.e. applying a function repeatedly, using the output from one iteration as the input to the next.
Addition reactionIn organic chemistry, an addition reaction is an organic reaction where two or more molecules combine to form a larger one (the adduct). Addition reactions are limited to chemical compounds that have multiple bonds, such as molecules with carbon–carbon double bonds (alkenes), or with triple bonds (alkynes), and compounds that have rings, which are also considered points of unsaturation. Molecules containing carbon—hetero double bonds like carbonyl () groups, or imine () groups, can undergo addition, as they too have double-bond character.
White privilegeWhite privilege, or white skin privilege, is the societal privilege that benefits white people over non-white people in some societies, particularly if they are otherwise under the same social, political, or economic circumstances. With roots in European colonialism and imperialism, and the Atlantic slave trade, white privilege has developed in circumstances that have broadly sought to protect white racial privileges, various national citizenships, and other rights or special benefits.
White supremacyWhite supremacy is the belief that white people are superior to those of other races and thus should dominate them. The belief favors the maintenance and defense of any power and privilege held by white people. White supremacy has roots in the now-discredited doctrine of scientific racism and was a key justification for European colonialism. As a political ideology, it imposes and maintains cultural, social, political, historical, and/or institutional domination by white people and non-white supporters.
White nationalismWhite nationalism is a type of racial nationalism or pan-nationalism which espouses the belief that white people are a race and seeks to develop and maintain a white racial and national identity. Many of its proponents identify with the concept of a white ethnostate. White nationalists say they seek to ensure the survival of the white race, and the cultures of historically white states. They hold that white people should maintain their majority in majority-white countries, maintain their political and economic dominance, and that their cultures should be foremost in these countries.
White AmericansWhite Americans (also referred to as European Americans) are Americans who identify as white people. This group constitutes the majority of the people in the United States. According to the 2020 census, 71%, or 235,411,507 people, were White alone or in combination, and 61.6%, or 204,277,273 people, were White alone. This represented a national white demographic decline from a 72.4% white alone share of the U.S. population in 2010. As of July 1, 2022, United States Census Bureau estimates that 75.
Whiteness studiesWhiteness studies is the study of the structures that produce white privilege, the examination of what whiteness is when analyzed as a race, a culture, and a source of systemic racism, and the exploration of other social phenomena generated by the societal compositions, perceptions and group behaviors of white people. It is an interdisciplinary arena of inquiry that has developed beginning in the United States from white trash studies and critical race studies, particularly since the late 20th century.
