Need

A need is something that is necessary for an organism to live a healthy life. Needs are distinguished from wants in that, in the case of a need, a deficiency causes a clear adverse outcome: a dysfunction or death.

Needs can be objective and physical, such as the need for food, or subjective and psychological, such as the need for self-esteem.

There are also needs of a social or societal nature.

Needs and wants are a matter of interest in, and form a common substrate for, the fields of philosophy, biology, psychology, social science, and politics.

Psychological definition

To most psychologists, need is a psychological feature that arouses an organism to action toward a goal, giving purpose and direction to behavior.

The most widely known academic model of needs was proposed by psychologist Abraham Maslow. His theory proposed that people have a hierarchy of psychological needs, which range from security to self-actualization. However, while intuitively appealing, this model has been difficult to operationalize experimentally. It was developed further by Clayton Alderfer.

Copper

Copper is a chemical element with symbol Cu (from Latin: cuprum) and atomic number 29. It is a soft, malleable and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a reddish-orange color. It is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys.

Copper is found as a pure metal in nature, and this was the source of the first metal to be used by humans, ca. 8,000 BC; it was the first metal to be smelted from its ore, ca. 5,000 BC; it was the first metal to be cast into a shape in a mold, ca. 4,000 BC; and it was the first metal to be purposefully alloyed with another metal, tin, to create bronze, ca. 3,500.

In the Roman era, copper was principally mined on Cyprus, the origin of the name of the metal from aes сyprium (metal of Cyprus), later corrupted to сuprum, from which the words copper (English), cuivre (French), Koper (Dutch) and Kupfer (German) are all derived. Its compounds are commonly encountered as copper(II) salts, which often impart blue or green colors to minerals such as azurite, malachite and turquoise and have been widely used historically as pigments. Architectural structures built with copper corrode to give green verdigris (or patina). Decorative art prominently features copper, both by itself and in the form of pigments.
