What is quantum theory? Detailed answer Directory / Big encyclopedia. Questions for quiz and self-education Did you know? What is quantum theory? Light is still a huge mystery to man. We know that light travels in waves and that light waves are made up of electrical and magnetic vibrations going together. This is a type of electromagnetic wave. In 1900, the German physicist Max Planck discovered that the wave character did not fully reveal the theory of light. He tried to explain how a hot object emits radiation. According to his theory, radiation is emitted not in a constant, continuous stream, but in small portions. Each small burst of energy is called a quantum of light. Planck's idea is now called quantum theory. A single quantum of radiation energy is so small that its flow seems to be continuous. For example, even from such a weak source as starlight, 60 quanta of light per second reach our eyes, and the light appears to be continuous. Today, physicists consider light, on the one hand, as a wave theory, on the other hand, as a quantum theory. No single idea, by itself, can explain the phenomenon. The wave theory fully explains what happens when radiation travels through space or through matter. And quantum theory explains how radiation occurs and what happens to it when it is absorbed by matter. Light and other types of electromagnetic radiation are very complex phenomena. Therefore, it is not surprising that neither wave nor quantum theory alone can explain what is happening. Author: Likum A. Random interesting fact from the Great Encyclopedia: Who were the first nuns? Monasticism means a way of life devoted to religion. A male monastery is a building in which men who have taken a religious vow live. These men are usually monks, but priests and members of a religious brotherhood may also live in monasteries. A convent is a building in which women who have taken a religious vow live. These women are called nuns. Monasticism was practiced long before Christian times. Groups of Jews lived in communities and ran their households. Christian monasticism began in Egypt in the third century AD. Groups of men left society in order to lead a solitary life and pray. Religious groups of women have also existed since very ancient times. But some people believe that women's monasteries were organized before men's. In the history of Christianity, when an order of monks arose, religious women's societies always appeared. Most religious women's societies are governed by the charter of St. Augustine or St. Francis. Nuns take vows in the same way as monks. They live in nunneries, each of which has its own form of clothing. Until the seventeenth century, nuns usually remained in monasteries and spent their lives in prayer. But since that time, many societies of nuns began to work in schools, hospitals, orphanages, nursing homes.
