It was during the 16th and 17th centuries when man’s view of the unvierse and himself

contributed greatly to the devolopment in these areas. In the field of astronomy
Copernicus, Brahe, Kepler, and Galileo shed Aristotle’s, Plato’s, and Ptolemy’s views of

the Earth spinning around, therefore it couldn’t be moving. Also if the Earth were
all this evidence there was no way that the Earth could be moving.
There were however a few descrepencies in this Earth stationary or geocentric
view. The most apparent being the five planets. They moved unlike anything else, they
correct this by the use of epicycles. This said that not only do planets orbit the Earth, but
they also have smaller circular moton which they perform during their orbit. This did
solve the problem, but it was still imperfect and very complicated, it was un-Godlike.
really true. Also people didn’t observe any shift in the stars throughout the year, which
looked at from different sides of the sun. Unless of course they were really far away, but
that didn’t make sense because God wouldn’t waste that much space.
Tycho Brahe spent most of his life studying the movements of the celestial bodies.
His calculations led him to create a third view of the universe. He said that the planets
revolved around the sun, and the sun, moon, and stars revolve around the Earth. It had
died he gave all his calculations to Johaness Kepler. Kepler revised Copernicus’s model
of a heliocentric universe. The big difference was that he said that the planets moved in
ellipses, with the sun at one focus. To account for the planets’ motion he said that they
must move a variable speeds.
It was Galileo Galilei who came up with the ‘proof’ for a heliocentric universe. In
view of the universe wrong. He saw new stars which had never been seen before, which
craters which proved that the Earth wasn’t the only thing that decayed. The moons of

despite the fact that he could onyl dissect animals. His works were studied, and
considered the highest authority on anatomy. Anyone who studied medicine, studied
argued against the work of Galen and against the church. He, like Copernicus, went
against the norm, and preeched what he believed.
It was Andreas Vesalius who first went against Galen anatomy. He wrote De
humani corporis fabrica, an illustrated book which included information he had gathered
from performing his own disections. Tycho Brahe who spent his life collecting data,
Vesalius collected the information for himself too.
said that the heart was a pump, rather than a heat generating organ. He published On the
physiology. Much like Galileo who gave the proof for the heliocentric world, he gave the
proof for the modern view of the human body.
Boorstin puts it in The Discovers, was finally over. Man had stopped believing
everything that it was told, and had gone out to prove it for himself. The human body
and the universe were never looked at the same way again. It only took a few smart
people, who willing to speak out, to change the world
