Conducting Path Between: GROUND, in electricity, a conducting path between path between electrical equipment and the earth or some large conducting path between body that serves in place of the earth. The path may be an intentional connection, such as one made by embedding a metal rod in the soil, or it may be an accidental connection, such as when wire Insulation fails. The chief function of an intentional ground connection is to protect people from the risk of electric shock.
Wave Propagation Path. Maxwell's electromagnetic wave theory had made it possible to calculate how radio waves would diffract around the conducting path between curved surface of the earth. In 1901, Marconi's transatlantic signaling showed that something more than diffraction must be involved in the long-distance propagation of radio waves. One year later Oliver Heaviside (q.v.) and Arthur Kennelly (q.v.) both suggested that a conducting path between layer of ionized gas high in the earth's atmosphere would help to explain Marconi's feat.
The arrangement of paving units in a path can subtly affect the speed at which you walk. A uniform grain along the path—for example, that created by bricks laid lengthwise in stretcher bond—can seem to hurry you on, whereas a less directional pattern will encourage a slower pace. The treatment may be chosen to suit the purpose of the path—a "slow" path where there is plenty to admire, a "faster" path where the aim is simply to provide access to another part of the garden.
