World history or global history as a field of historical study examines history from a global perspective. It emerged centuries ago; leading practitioners have included Voltaire (1694–1778), Hegel (1770–1831), Karl Marx (1818–1883) and Arnold J. Toynbee (1889–1975). The field became much more active in the late 20th century. It is not to be confused with comparative history, which, like world history, deals with the history of multiple cultures and nations, but does not do so on a global scale. World history looks for common patterns that emerge across all cultures. World historians use a thematic approach, with two major focal points: integration and difference.
Paul Anthony Samuelson was an American economist, who was the first American to win the Nobel Memorial Prize in Economic Sciences. When awarding the prize in 1970, the Swedish Royal Academies stated that he "has done more than any other contemporary economist to raise the level of scientific analysis in economic theory". Economic historian Randall E. Parker has called him the "Father of Modern Economics", and The New York Times considers him to be the "foremost academic economist of the 20th century".

A mathematical exercise is a routine application of algebra or other mathematics to a stated challenge. Mathematics teachers assign mathematical exercises to develop the skills of their students. Early exercises deal with addition, subtraction, multiplication, and division of integers. Extensive courses of exercises in school extend such arithmetic to rational numbers. Various approaches to geometry have based exercises on relations of angles, segments, and triangles. The topic of trigonometry gains many of its exercises from the trigonometric identities. In college mathematics exercises often depend on functions of a real variable or application of theorems. The standard exercises of calculus involve finding derivatives and integrals of specified functions.
Classical Electrodynamics is a textbook about that subject written by theoretical particle and nuclear physicist John David Jackson.
