Zero was invented independently by the Babylonians,

Mayans and Indians (although some researchers say the Indian number system was influenced by the Babylonians).

The Babylonians got their number system from the Sumerians, the first people in the world to develop a counting system.

n its simplest form: a line describes one dimension,

a plane describes two dimensions,

a cube describes three dimensions.

(See Space and Cartesian coordinate system.)

Zero Dimensions: A point has zero dimensions.

One Dimension: Once you connect two points, you get a one-dimensional object —

a line segment.

A line segment has one dimension: length.

Two Dimensions: A flat plane or shape is two-dimensional.

The Scottish mathematician John Napier published his discovery of logarithms in 1614.

His purpose was to assist in the multiplication of quantities that were then called sines.

The whole sine was the value of the side of a right-angled triangle with a large hypotenuse.

Ramanujan replied that 1729 was not a boring number at all

it was a very interesting one.

He explained that it was the smallest number that could be expressed by the sum of two cubes in two different ways.

This story is very famous among mathematicians.

1729 is sometimes called the “Hardy-Ramanujan number”.
