Mental health can be defined as “a state of emotional and psychological well-being in which an individual is able to use his or her cognitive and emotional capabilities, function in society, and meet the ordinary demands of everyday life”. Mental health is not mere absence of mental illness. Mental illness can be classified into three types: psychosis, neurosis and epilepsy. Addiction is a chronic progressive and sometimes fatal disorder with both genetic and environmental roots.

In organ transplantation, the transplantation of cornea is easy but other are more complicated. So the principle of histocompalibility should be applied. In this process, the most significant drawback is that the body in which organ is transplanted do not accept it because it recognizes non-self organ and therefore, its immune system is triggered. Body wants to reject the non-self organ.

In the universe, there are different types of force but I am going to explain about these forces which created in the origin of the universe. These forces are strong force, weak force, electromagnetic force and gravitational force. In the time of big bang, these four fundamental forces were believed as a single force, called unified force.

When we throw any object into sky, then it returns back to earth’s surface. Rivers and streams flow downward from hills and mountains. Rainfall occurs in the downward direction. Earth revolves around sun and moon revolves around earth. Eight planets of solar system moves around the sun. Atmosphere surrounds the earth.

What’s A Google?
When you hear the word Google the first image that comes to mind has to be the famous internet search engine but does the word actually mean anything? Well the answer is a firm yes because it comes from the term “Googol” which represents a number (written as a 1 followed by 100 zeros) so large that it’s actually larger than the total number of atoms in the known universe.Tortoise of turtle
All tortoises are turtles but not all turtles are tortoises.
You know it is a tortoise if it
· lives on land
· eats only planets
· has a large, hard, domelike shell
· is hidden-necked.
Nobel Prize in Physics 2010 for Graphene -- 'Two-Dimensional' Material
The Royal Swedish Academy of Sciences has awarded the Nobel Prize in Physics for 2010 to Andre Geim and Konstantin Novoselov, both of the University of Manchester, "for groundbreaking experiments regarding the two-dimensional material graphene."

A thin flake of ordinary carbon, just one atom thick, lies behind this year's Nobel Prize in Physics. Geim and Novoselov have shown that carbon in such a flat form has exceptional properties that originate from the remarkable world of quantum physics.

Global warming refers to the rising global temperature. It causes climate change that is responsible for: flood; frequent and intense rain and snow; change in the normal occurrence of monsoon thereby affecting crop production; drought; land slide; vector borne diseases; more frequent tropical storms; forest fire and extinction of species due to the loss of ecological niches.
Scientists all over the world believe that global warming is caused mainly by two processes as given below:
1) Increase in the level of green house gases such as carbon dioxide (Co2), chlorofluorocarbons (CFCS), methane and water vapour due to burning of fossil fuel and deforestation.
2) Milankovitch cycle

Space Quick Facts
1. The Sun looks 1600 times fainter from Pluto than it does from the Earth.
2. There is a supemassive black hole right in the middle of the Milky Way galaxy that is 4 million times the mass of the Sun.
3. There are over 20 million observable meteors per day.
4. Only one or two meteorites per day reach the surface of Earth.
5. The typical size of a meteor is about one cubic centimeter, which is equivalent to the size of a sugar cube.
6. Each day, Earth accumulates 10 to 100 tons of material.
7. A piece of a neutron star the size of a pin point would way 1 million tons.
8. Light reflecting off the moon takes 1.2822 seconds to reach Earth.
9. There has only been one satellite destroyed by a meteor, it was the European Space Agency’s Olympus in 1993.
10. The International Space Station orbits at 248 miles above the Earth.
11. The Earth orbits the Sun at 66,700mph.
