Capon Capon A capon (from ) is a cockerel (rooster) that has been castrated to improve the quality of its flesh for food and, in some countries like Spain, fattened by forced feeding. In the United Kingdom, birds sold as capons are chemically or physically castrated cocks. The origins of caponised chickens are contested. They were known in ancient China as well as in ancient Greece and ancient Rome. An early record of caponisation is found under the Roman Republic: the Lex Faunia of 162 BC forbade fattening hens to conserve grain rations, so the Romans instead castrated roosters, which resulted
S-wave S-wave In seismology, S-waves, secondary waves, or shear waves (sometimes called an elastic S-wave) are a type of elastic wave, and are one of the two main types of elastic body waves, so named because they move through the body of an object, unlike surface waves. The S-wave moves as a shear or transverse wave, so motion is perpendicular to the direction of wave propagation. The wave moves through elastic media, and the main restoring force comes from shear effects. These waves do not diverge, and they obey the continuity equation for incompressible media: Its name, S for secondary, comes
