The Purpose of Education
1. Some educational theorists believe that education should serve the needs of the individual. The second opinion on the purpose of education is that education should serve the needs of the society. In industrialized nations it is common for both of these goals to be held but for different classes of the population.
2. For the elite, the needs of the individual tend to prevail, and thus upper-class schooling often tolerates diversity and encourages idiosyncrasy. For the masses, the needs of society tend to dominate, and schooling usually serves to prepare children to become obedient, well-drilled, uncomplaining workers in industry and agriculture.
3. In France and Germany, the primary purpose of education is intellectual development. In England, the primary purpose of education is character building. In Roman Catholic and Communist countries, moral or religious training is usually the primary purpose of education. Hence, every subject is imbued with religious or ideological content, and there is a constant attempt to draw moral lessons from educational material. In the United States, where large-scale immigration once brought the fear of social disintegration, preparation for citizenship and development of national consciousness have tended to be emphasized. Even today, some rituals, such as displaying American flags here there and everywhere and pledging allegiance to the flag of the United States of America at the beginning of the school day, distinguish American schools from those in most other countries.

Nuclear physics
1. The study of the nucleus of an atom is known as nuclear physics. As a result of this study, scientists have discovered ways of splitting the nucleus to release huge amounts of energy. There are two types of nuclear reactions: nuclear fission and nuclear fusion. A controlled nuclear reaction inside a power station can be used to provide heat and light for our homes.
2. Nuclear power stations use fission to produce their energy. Fast-moving atomic particles called neutrons are fired at the nucleus of an atom to split it. This splitting is called fission and it causes other atoms to split in a chain reaction. Some mass (the number of heavy particles inside an atom) is lost in the process. This is converted into large amounts of nuclear energy.
3. Nuclear fusion is a type of nuclear reaction that creates huge amounts of energy. It takes place naturally inside the sun, creating the heat energy that we need to survive on Earth. At temperatures of about 14 million C dgr. the nuclei of two hydrogen atoms fuse, or join together. In the process, some mass (the number of heavy particles inside an atom) is lost and converted into energy. Scientists are trying to develop this form of nuclear reaction as a safer alternative to the nuclear fission that takes place in power stations.

Solar energy
1. Solar energy, radiant light and heat from the sun, has been harnessed by humans since ancient times using a range of different technologies. Solar radiation, along with secondary solar-powered resources such as wind and wave power, hydroelectricity and biomass, account for most of the available renewable energy on the Earth. Only a minuscule fraction of the available solar energy is used.
2. Solar powered electrical generation relies on heat engines and photovoltaics. Solar energy's uses are limited only by human ingenuity. A partial list of solar applications includes space heating and cooling through solar architecture, potable water via distillation and disinfection, daylighting, high temperature process heat for industrial purposes. To harvest the solar energy, the most common way is to use solar panels.
3. Solar technologies are broadly characterized as either passive solar or active solar depending on the way they capture, convert and distribute solar energy. Active solar techniques include the use of photovoltaic panels and solar thermal collectors to harness the energy. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light dispersing properties, and designing spaces that naturally circulate air.

Gravitation
1. Gravitation is a natural phenomenon by which physical bodies attract with a force proportional to their mass. In everyday life, gravitation is most familiar as the agent that gives weight to objects with mass and causes them to fall to the ground when dropped. Gravitation causes dispersed matter to coalesce, and coalesced matter to remain intact, thus accounting for the existence of the Earth, the Sun, and most of the macroscopic objects in the universe.
2. Gravitation is responsible for keeping the Earth and the other planets in their orbits around the Sun; for keeping the Moon in its orbit around the Earth; for the formation of tides; for natural convection, by which fluid flow occurs under the influence of a density gradient and gravity; for heating the interiors of forming stars and planets to very high temperatures; and for various other phenomena observed on the Earth.
3. Gravitation is one of the four fundamental interactions of nature, along with electromagnetism, and the nuclear strong force and weak force. Modern physics describes gravitation using the general theory of relativity by Einstein, in which it is a consequence of the curvature of spacetime governing the motion of inertial objects. The simpler Newton's law of universal gravitation provides an accurate approximation for most physical situations.
