Heun's methodIn mathematics and computational science, Heun's method may refer to the improved or modified Euler's method (that is, the explicit trapezoidal rule), or a similar two-stage Runge–Kutta method. It is named after Karl Heun and is a numerical procedure for solving ordinary differential equations (ODEs) with a given initial value. Both variants can be seen as extensions of the Euler method into two-stage second-order Runge–Kutta methods.
Rate of returnIn finance, return is a profit on an investment. It comprises any change in value of the investment, and/or cash flows (or securities, or other investments) which the investor receives from that investment over a specified time period, such as interest payments, coupons, cash dividends and stock dividends. It may be measured either in absolute terms (e.g., dollars) or as a percentage of the amount invested. The latter is also called the holding period return.
Early modern periodThe early modern period of modern history spans the period after the Late Middle Ages of the post-classical era (1400–1500) to the beginning of the Age of Revolutions (1800). Although the chronological limits of this period are open to debate, the timeframe is variously demarcated by historians as beginning with the fall of Constantinople in 1453, the Renaissance period in Europe and Timurid Central Asia, the end of the Crusades, the Age of Discovery (especially the voyages of Christopher Columbus beginning in 1492 but also Vasco da Gama's discovery of the sea route to India in 1498), and ending around the French Revolution in 1789, or Napoleon's rise to power.
Scottish EnlightenmentThe Scottish Enlightenment (Scots Enlichtenment, Soillseachadh na h-Alba) was the period in 18th- and early-19th-century Scotland characterised by an outpouring of intellectual and scientific accomplishments. By the eighteenth century, Scotland had a network of parish schools in the Scottish Lowlands and five universities. The Enlightenment culture was based on close readings of new books, and intense discussions which took place daily at such intellectual gathering places in Edinburgh as The Select Society and, later, The Poker Club, as well as within Scotland's ancient universities (St Andrews, Glasgow, Edinburgh, King's College, and Marischal College).
Late modernityLate modernity (or liquid modernity) is the characterization of today's highly developed global societies as the continuation (or development) of modernity rather than as an element of the succeeding era known as postmodernity, or the postmodern. Introduced as "liquid" modernity by the Polish sociologist Zygmunt Bauman, late modernity is marked by the global capitalist economies with their increasing privatization of services and by the information revolution.
Dialectic of EnlightenmentDialectic of Enlightenment (Dialektik der Aufklärung) is a work of philosophy and social criticism written by Frankfurt School philosophers Max Horkheimer and Theodor W. Adorno. The text, published in 1947, is a revised version of what the authors originally had circulated among friends and colleagues in 1944 under the title of Philosophical Fragments (Philosophische Fragmente). One of the core texts of critical theory, Dialectic of Enlightenment explores the socio-psychological status quo that had been responsible for what the Frankfurt School considered the failure of the Age of Enlightenment.
Marxist feminismMarxist feminism is a philosophical variant of feminism that incorporates and extends Marxist theory. Marxist feminism analyzes the ways in which women are exploited through capitalism and the individual ownership of private property. According to Marxist feminists, women's liberation can only be achieved by dismantling the capitalist systems in which they contend much of women's labor is uncompensated. Marxist feminists extend traditional Marxist analysis by applying it to unpaid domestic labor and sex relations.
Polish EnlightenmentThe ideas of the Age of Enlightenment in Poland were developed later than in Western Europe, as the Polish bourgeoisie was weaker, and szlachta (nobility) culture (Sarmatism) together with the Polish–Lithuanian Commonwealth political system (Golden Liberty) were in deep crisis. The period of Polish Enlightenment began in the 1730s–40s, peaked in the reign of Poland's king, Stanisław August Poniatowski (second half of the 18th century), went into decline with the Third Partition of Poland (1795) – a national tragedy inspiring a short period of sentimental writing – and ended in 1822, replaced by Romanticism.
Return statementIn computer programming, a return statement causes execution to leave the current subroutine and resume at the point in the code immediately after the instruction which called the subroutine, known as its return address. The return address is saved by the calling routine, today usually on the process's call stack or in a register. Return statements in many programming languages allow a function to specify a return value to be passed back to the code that called the function.
Historical fictionHistorical fiction is a literary genre in which the plot takes place in a setting related to the past events, but is fictional. Although the term is commonly used as a synonym for historical fiction literature, it can also be applied to other types of narrative, including theatre, opera, cinema, and television, as well as video games and graphic novels. An essential element of historical fiction is that it is set in the past and pays attention to the manners, social conditions and other details of the depicted period.
