Actions Quotes

Actions refers to something done so as to accomplish a purpose. It commonly describes a way of motion or functioning, fast-paced activity, and a mechanism; a moving part or assembly, which gives the term a broader and more practical sense than a single short definition would suggest. Depending on context, it can also point to the mechanism, that is the set of moving mechanical parts, of a keyboard instrument, like a piano, which transfers the motion of the key to the sound-making device, the distance separating the strings and the fretboard on a guitar, and sexual intercourse, so the category can cover literal uses, related ideas, and more figurative extensions of the same core meaning. Taken together, these meanings present Actions as a flexible theme rather than a narrowly technical label, covering the central idea people usually mean when they use the word while still leaving room for closely related senses that appear in real language. Additional shades of meaning include combat, a charge or other process in a law court (also called lawsuit and actio), a mapping from a pairing of mathematical objects to one of them, respecting their individual structures. The pairing is typically a Cartesian product or a tensor product. The object that is not part of the output is said to act on the other object. In any given context, action is used as an abbreviation for a more fully named notion, like group action or left group action, the product of energy and time, especially the product of the Lagrangian and time, and the event or connected series of events, either real or imaginary, forming the subject of a play, poem, or other composition; the unfolding of the drama of events, which reinforce how the category can stretch across adjacent but still recognizable uses of the same term.
