As a result, book-sized computers of today can outperform room-sized computers of the 1960s, and there has been a revolution in the way people live – in how they work, study, conduct business, and engage in research. World War II had a profound impact on the development of science and technology in the United States.
The Next Generation Science Standards (NGSS) are based on the "Framework K–12 Science Education" that was created by the National Research Council. They have three dimensions that are integrated in instruction at all levels. The first dimension is the Disciplinary Core Ideas (the DCIs), which consists of content and concepts specific to four ...
Energy level. En = energy eigenvalue. n = principal quantum number. e = electron charge. me = electron rest mass. ε0 = permittivity of free space. h = Planck constant.

The world's first electronic digital computer, the Atanasoff–Berry computer, was built on the Iowa State campus from 1939 through 1942 by John V. Atanasoff, a professor of physics and mathematics, and Clifford Berry, an engineering graduate student. In 1941, Konrad Zuse developed the world's first functional program-controlled computer, the Z3.
The position of science and technology in Nazi Germany was completely determined by party instructions and the political atmosphere established in the country. The state and party apparatuses, largely educated people from the lower classes of society, due to their inherent distrust and unfriendly attitude towards any knowledge, in principle did ...
Holt McDougal is an American publishing company, a division of Houghton Mifflin Harcourt, that specializes in textbooks for use in high schools.. The Holt name is derived from that of U.S. publisher Henry Holt (1840–1926), co-founder of the earliest ancestor business, but Holt McDougal is distinct from contemporary Henry Holt and Company, which claims the history from 1866.
Beverton–Holt model. The Beverton–Holt model is a classic discrete-time population model which gives the expected number n t+1 (or density) of individuals in generation t + 1 as a function of the number of individuals in the previous generation, Here R0 is interpreted as the proliferation rate per generation and K = ( R0 − 1) M is the ...
The Elektronika MK-51 calculator, introduced in 1982. Science and technology in the Soviet Union served as an important part of national politics, practices, and identity. From the time of Lenin until the dissolution of the USSR in the early 1990s, both science and technology were intimately linked to the ideology and practical functioning of ...
