Teaduslik revolutsioon
A rudimentary telescope was the result. Galileo made his own
telescope as well as a compound microscope. Galileo directed all of his attention to the heavens. He was the
first man to see craters on the moon, sun spots and the rings of Saturn. He also observed the phases of
Venus. He determined that the Earth's moon was not a source of light but rather of reflected light. He saw the
moons of Jupiter. And of course, Galileo was also a Copernican: "Sol est centrum mundi, est omnio immobile
motu locali," ("The sun is the center of the universe and the earth moves.")
In 1611, Galileo packed his brass telescope in his bag and decided to go to Rome. Criticism of Galileo's
observations began immediately. The authorities at Rome would not even look through his telescope. Why
not? They had absolute faith in Aristotle. Not only that, if you think about it, the telescope reveals the
existence of things which are not really there
