He used the pooping theory, allied with thought and intelligence.
Oh, and he paid attention to his studies and read his books properly.
Nicolas Copernicus did not use a telescope, the use of the telescope to study the solar system was not done until over 50 years later by Galileo.
Some of his achievements were mathematically proving that earth and other planets orbited the sun and also improving the telescope to actually prove that theory. Now, of course he did much more, but those are just some of the things he's most known for.
A psychologist would use the scientific method to test a theory, just as any other scientist would.
As much as they need to prove a theory.
He was too scared to publish his work because he was afraid of being caught by the Church, which strongly believed in the geocentric theory. Copernicus didn't publish his work until he was on his deathbed. Even when he did published it, it wasn't under his own name, instead under the name of 25-year-old George Rhetis.
yes he did
Galileo was the first scientist to use a telescope to make discoveries about the Sun, Moon and planets. His discoveries raised serious doubts about the ancient Ptolemaic theory in which the Earth is at the centre of the Universe. Copernicus's theory of 1543 places the Sun at the centre instead. It explains some of the things that the Ptolemaic theory fails to explain, like the full range of Venus's phases that Galielo discovered. Galileo reasoned that this must prove that Copernicus's theory is right. However Galileo was wrong about this because Tycho Brahe's model explains the phases of Venus correctly yet still has the Earth at the centre. In the end, all these theories were rejected when Johannes Kepler produced his new theory in which the planets travel in elliptical orbits. It was generally accepted later, after Newton's discoveries showed theoretically that the planets must move in elliptical orbits under the force of gravity. However, Kepler's theory did have the Sun at the centre, so in one respect Copernicus was right.
Copernicus, with the use of the heliocentric theory and Galileo with his telescope proved the planets revolve around the Sun.
To figure out formulas and equations and claculations to prove or add evidence to a theory.
what are you trying to prove? if you were trying to prove a lemon can make lemonade the lemon can be used as a product to ensure that the theory is in fact "feasible"
scientific method or postulation or a theory
Use Galileo Method. 1.put your head into full tank water. Then measure the mass of the water that come out.
