Psychology:-

Psychology is an academic and practical field relating the scientific study of mental procedures and conduct. Psychology as well refers to the application of such knowledge to a variety of spheres of human action, with troubles of persons' daily lives and the treatment of mental illness.

Psychology varies from the other social sciences — anthropology, economics, political science, and sociology — in looking for to make clear the mental procedures and conduct of individuals. Psychology differs from biology and neuroscience in that it is mainly concerned with the communication of mental procedures and actions on an entire level, as opposed to learning the biological or neural procedures themselves. Biological psychology is the scientific learning of the biological basis of conduct and mental conditions.

Ruby

Ruby is a red gemstone, a variety of the mineral corundum (aluminium oxide). The color is caused mainly by chromium. Its name comes from ruber, Latin for red. Natural rubies are exceptionally rare, but synthetic rubies (sometimes called created ruby) can be manufactured fairly cheaply. Other varieties of gem-quality corundum are called sapphires. It is considered one of the four precious gems together with the sapphire, the emerald and the diamond.

Rubies are mined in Africa, Asia, Australia,Greenland, andNorth Carolina. They are most often found in Myanmar (Burma), Sri Lanka, Kenya, Madagascar, and Thailand, but they have also been found in the U.S. states of Montana, North Carolina and South Carolina. The Mogok Valley in Myanmar has produced some of the finest rubies but in recent years very few good rubies have been found there. In central Myanmar the area of Mong Hsu also produces rubies. The latest ruby deposit to be found in Myanmar is situated in Nam Ya. In 2002 rubies were found in the Waseges River area of Kenya. Rubies are being mined at Audilamena in northeastern Madagascar. Sometimes spinels are found along with rubies in the same rocks and are mistaken for rubies. However, fine red spinels may approach the average ruby in value.
