Magellan for example, wanted to prove that the Earth was indeed round. And Christopher
Columbus (1450-1506)
is an Italian crusader who is tasked to look for Asia from Europe starting on
the west direction. His conquests during 15th to 20th
century in Asia, Australia, United States and Atlantic made new discoveries and
colonies crediting him as the explorer of the ‘New World’ or the ‘Age of
Discovery’. His conquests were very much celebrated however there also negative
effects on the system instilled on the newly-discovered places such as slavery,
diseases, illiteracy, rape and death.
The Ptolemaic theory of the universe was
disproved by Nicolaus Copernicus (1473–1543), letter C and followed by Johannes
Kepler (1571–1630). Geocentric
theory suggested that the Sun and moon orbited Earth, and the rest of the
planets orbited the Sun is Heliocentric theory. Heliocentric theory of Nicolaus
Copernicus during the Scientific Revolution on 17th and 18th
century while Geocentric theory was proposed by Ptolemy (AD 150) and Aristotle.
Today, we believe more on the Heliocentric theory and it has been proven as
well.
