I want to explore the world in in my life. The human has a great opportunity to explore the world. I am exploring it now by indirect in Wikipedia because in wikipedia we can see the every part of the world with their appropiate citation. I like to contribute to wikipedia because it exchange the knowledge over the universe and exchange & exploring of knowledge is the best way to develop our mind so that we could inspired & motivate by it and help the world for it future safety. Contributing to wikipedia play a graeat role in our daily life in the modern world.

Today's Featured ArticleThe number π (pi) is a mathematical constant, approximately equal to 3.14159, that is the ratio of a circle's circumference to its diameter. It is an irrational number, meaning that it cannot be expressed exactly as a ratio of two integers, though it is sometimes approximated as 22/7. Its decimal representation never ends, nor does it enter a permanently repeating pattern. The digits of π appear to be evenly distributed, but no proof of this conjecture has been found. It appears in many formulae in mathematics and physics, and for thousands of years mathematicians have computed its value with increasing accuracy. Since the late 20th century, mathematicians and computer scientists have extended the decimal representation of π to many trillions of digits. Many equations from trigonometry and geometry rely on π, especially those concerning circles and spheres. A transcendental number, π is one of the most widely known mathematical constants.
