FORM OF THE EARTH

.

it was believed that the earth was flat even as viewing square in the distance saw the end of which reaches to see the view to the horizon terminace in an edge which is clearly false .

.
The first philosopher to show that this theory was false Eratosthenes was a great philosopher, mathematician, cartographer, poet, writer, among other professions. He was the director of the massive Library of Alexandria founded by Alexander the Great in Egypt in this realiozo his studies and experiments ..

entered confusion to hear that in Aswan it was said that on the longest day of the year the shadow of a column did not generate an angle that is shaded from the sun light in that column ensima impacted thus generating a column without a shadow, in contrast to generating a shadow Alexandria lateral spine; Eratosthenes realized that for this to happen the earth would have to be spherical then sent a person to measure the distance between that column and the column located in Alexandria. A method for calculating this measurement came to the conclusion that if the earth was round and bring its size to 40,000 km which only had one error today's 2.000 km.

.

After the deduction was reached by Isacc Newton HEC could not be spherical but flattened at the poles spherical devido the effect of rotation of the Earth and who conducted an experiment to test the theory of Isaac Newton was Antonio Plateau with a rotation experiment consists of oil floating in water.
. Finally
far as is known that the Earth is actually a form of Geoid which means "way of the Earth" this means that the correct form of the earth is an ellipsoid in an irregular manner devido to form elevations and geological .
