BATTERIES |
|
In science and technology, a battery is a device that stores chemical energy and makes it available in an electrical form. Batteries consist of electrochemical devices such as one or more galvanic cells, fuel cells or flow cells. The earliest known artifacts that may have been batteries are the Baghdad Batteries, from some time between 250 BCE and 640 CE. The modern development of batteries started with the Voltaic pile developed by the Italian physicist Alessandro Volta in 1800. The worldwide battery industry generates 48 billion dollars in sales annually (2005 estimate).

DEATH PENALTY |
|
Capital punishment, or the death penalty, is governmental killing by execution as punishment for a crime often called a capital offense or a capital crime. Historically, the execution of criminals and political opponents was used by nearly all societies either by means of judicial process or through political motivations such as the supression of political dissent. Among democratic countries around the world, most European and Latin American ones have abolished capital punishment (except the United States, Guatemala and most of the Caribbean), while democracies in Asia and Africa retain it. Among nondemocratic countries the use of the death penalty is common.
