Hello steemit friend, this time I will introduce one named CLADIUS PTOLEMY who is the first and unforgettable person in the world of Cartography or earth map. And he was born in Alexandria about 150 BC, CLADIUS PTOLEMY is known as a scientist who observes and investigates the universe and is famous for his Geographi writing about mapping issues, including the luminous lines and the intersections of the earth, which at that time has never been triggered by people.
In Greece, the writings of CLADIUS PTOLEMY are very popular, many students respond with attention, and everyone wants to learn it. So since the Roman Empire the teachings of CLADIUS PTOLEMY began to be forgotten, but luckily copian-copian writing is still stored well in the monasteries.
CLADIUS PTOLEMY then abandoned a theory of the position of the universe now known as the Ptolemy System, in his opinion "the earth is the center of the movement of the universe, according to his belief, all planets move around the earth, besides that every planet moves in a circle or circle called epicycle.
A few years later there was born a man known as the Astronomy Father of the world or also called Modern Astronomy. He was born in 1473 called Nocolas Copernicus, which is famous after studying at the University in Crocow-Poland.
After years of experiments he Nocolas Copernicus concluded with his theory that "planets move in the sun". And is the opposite of that delivered by CLADIUS PTOLEMY.
