Story of ZERO

Here, in this post we describe the story behind the zero.How this zero changed the world,leave footprints on history and developed the hardcore mathematics.
Some historians said that zero is invented by Aryabhatta (476-550 A.D.) , one of the world's greatest mathematician-astronomer was born in Patilputra in Magadha. He wrote that if 4 is added to 100 and then multiplied by 8, and then added to 62,000 then divided by 20,000 the answer will be equal to the circumference of a circle of diameter twenty thousand. This calculates 3.1416 close to the actual value of pi (22/7).
But his greatest contribution in history is invention of ZERO, for which he became immortal. He certainly did not use the symbol, but the French mathematician Georges Ifrah argues that knowledge of Zero was implicit in Aryabhata's place-value system as a place holder for the powers of ten with null coefficients.The supposition is based on the following two facts:

• The invention of his alphabetical counting system would have been impossible without zero or the place-value system.
• He carries out calculations on square and cubic roots which are impossible if the numbers in question are not written according to the place-value system and zero.

In the context of world , in 5000 B.C. Egyptians had a system based on 10 , but they didn't use positional notation.Another from the history is  from Mesopotamia in (3000 B.C.) had a sexagesimal system using base 60. Greeks and Romans had a cumbersome system ( try to write 3276 in Roman numerals.)

The Indians were first to see that can be used for something beyond nothing - at different places in a number, it adds different values. For e.g 87 is different from 807, 8007, 870 etc, Brahmgupta( 598 AD-660  AD) was first to give the rules of operation of zero.

X+0=X ,where x is any quantity,

X-0=X,

X*0=0,

X/0=Not Defined

The ancient Indians represented zero as a circle with a dot inside. In Sanskrit, it was called "Soonya".

This is all from the history, now the most important part is how Zero changed our world. Now can we imagine mathematics without zero, physics is incomplete without zero ?? How can we Evaluate the marks of  a student?? How NASA calculate any calculations for its space mission ? How we calculate the time ?? There are so many things which is incomplete if ZERO was not discovered.

Without Zero world is nothing. So you can imagine that how Zero CHANGED THE WORLD.
