An electric current is a flow of charged particles, such as electrons or ions, moving through an electrical conductor or space. It is defined as the net rate of flow of electric charge through a surface. [1]: 2 [2]: 622 The moving particles are called charge carriers, which may be one of several types of particles, depending on the conductor.
Electric current can flow through some things, electrical conductors, but will not flow through an electrical insulator. [42] By historical convention, a positive current is defined as having the same direction of flow as any positive charge it contains, or to flow from the most positive part of a circuit to the most negative part.

Additionally, science and technology were seen to have greatly added to the Allied war victory, and were seen as absolutely crucial in the Cold War era. This enthusiasm simultaneously rejuvenated American industry, and celebrated Yankee ingenuity, instilling a zealous nationwide investment in "Big Science" and state-of-the-art government funded ...

Science and technology studies (STS) or science, technology, and society is an interdisciplinary field that examines the creation, development, and consequences of science and technology in their historical, cultural, and social contexts.
Science is a systematic discipline that builds and organises knowledge in the form of testable hypotheses and predictions about the universe. [1] [2] Modern science is typically divided into two or three major branches: [3] the natural sciences (e.g., physics, chemistry, and biology), which study the physical world; and the social sciences (e.g., economics, psychology, and sociology), which ...
