Lightning Arrester         
  • Base of a mast radiator with spark gap and series inductance in form of a coil with one winding in the feeder line
  • The antenna is attached to A, and a pipe in the ground is attached to E. The television signal can go from A to B but not from B to C or from C to D. However, when the high voltage of lightning hits, it can easily go through the air from B to C and from C to D and E.
DEVICE IN POWER/TELECOMMUNICATION SYSTEMS THAT PROTECTS AGAINST LIGHTNING, SUCH THAT WHEN A LIGHTNING SURGE HAPPENS, THE CURRENT IS DIVERTED THROUGH THE ARRESTER TO EARTH
Lightning arrestor; Lightning diverter
An apparatus for use with electric lines to carry off to earth any lightning discharge such lines may pick up. Such discharge would imperil life as well as property in telegraph offices and the like. Arresters are generally constructed on the following lines. The line wires have connected to them a plate with teeth; a second similar plate is placed near this with its teeth opposite to those of the first plate and nearly touching it. The second plate is connected by a low resistance conductor to ground. Any lightning discharge is apt to jump across the interval, of a small fraction of an inch, between the oppositely placed points and go to earth. Another type consists of two plates, placed face to face, and pressing between them a piece of paper or mica. The lightning is supposed to perforate this and go to earth. One plate is connected to the line, the other one is grounded. The lightning arrester is placed near the end of the line before it reaches any instrument. (See Alternative Paths.) Fig. 215. COMB OR TOOTHED LIGHTNING ARRESTER. Fig. 216. FILM OR PLATE LIGHTNING ARRESTER. Lightning Arrester, Counter-electro-motive Force. An invention of Prof. Elihu Thompson. A lightning arrester in which the lightning discharge sets up a counter-electro-motive force opposed to its own. This it does by an induction coil. If a discharge to earth takes place it selects the primary of the coil as it has low self-induction. In its discharge it induces in the secondary a reverse electro-motive force which protects the line.

Lightning arrestor; Lightning diverter
A lightning arrester (alternative spelling lightning arrestor) (also called lightning isolator) is a device used on electric power transmission and telecommunication systems to protect the insulation and conductors of the system from the damaging effects of lightning. The typical lightning arrester has a high-voltage terminal and a ground terminal.

False vacuum decay

In quantum field theory, a false vacuum is a hypothetical vacuum that is relatively stable, but not in the most stable state possible. This condition is known as metastable. It may last for a very long time in that state, but could eventually decay to the more stable state, an event known as false vacuum decay. The most common suggestion of how such a decay might happen in our universe is called bubble nucleation – if a small region of the universe by chance reached a more stable vacuum, this "bubble" (also called "bounce") would spread.

A false vacuum exists at a local minimum of energy and is therefore not completely stable, in contrast to a true vacuum, which exists at a global minimum and is stable.
