Why was it difficult for ancient astronomers to explain about the apparent retrograde motion?
If, as ancient astronomers thought, that our Earth was the center point of rotation for other planets, then it is difficult to explain why those planets would move in a direction opposite to their rotation. Ptolemy came up with a solution that worked, but it was a cumbersome one. Nicolae Copernicus was able to show that this retrograde motion could be explained easily if it were assumed that our Sun was the actual center of rotation of the planets.
How did Kepler disagree with the theorys of Copernicus?
Johannes Kepler found out that planets move in ellipses and move at variable speeds as they travel round the sun. The former theory of Copernicus was not wrong, but Kepler's theory was found to be more accurate when accurate observational methods were developed. Later Kepler's theory was backed up by theory when Newton's law of gravitation came along. However in the 20th century Einstein's theory of relativity produced some small corrections to the Kepler/Newton theory.
When did the majority of people start to believe in a heliocentric galexy?
This explains the input of several astronomers into this theory. Copernicus: In 1418-30, he did his work on 'On the Revolutions of Celestial Spheres' In this book, he suggested that Earth rotated daily on its axis and that it orbits the Sun every year. He also said that other planets also rotated around the Sun, and that the Earth wobbled slightly as it span on its orbit. His theory, did not disagree completely with the older ideas; he still said that there were solid planet bearing spheres and that the outermost sphere contained the stars. He also explained that the Earth was not at the centre of the Universe. This caused uproar in the Catholic Church, because it disagreed with the God's Perfect Creation theory. Galileo: Galileo first studied the moon. He discovered that the moon was not smooth, but heavily cratered. He went on to discover, four satellites (moons) orbiting Jupiter. After this, he then discovered Saturn's rings, but he did not know what they were. These discoveries, made it very difficult to defend the perfect universe theory, with perfect smooth bodies of all the objects. He then noticed that Venus went through phases like the moon (ie: full, half, new etc.). This proved that Venus could not be orbiting the Earth, but had to be orbiting the Sun. After Copernicus' and Galileo's theories, the Inquisition of Rome was formed saying that after looking into the theories, they were absurd. They said that they were heretical. Eventually, Galileo was charged by the Inquisition, and was put under house arrest. Kepler: In 1592, Kepler became an apprentice to Brahe, a man who owned the largest collection of astronomical instruments in the world. When Brahe died, Kepler inherited them all. He immediately sent Galileo a message of encouragement, and then looked at a calculation that Galileo had sent him. Using Brahe's charts, Kepler was able to show that planets had elliptical orbits, and that this usually was the case. However, he soon died in poverty, as Protestant beliefs disagreed with his findings.

Who is the inventor of insulin?
The insulin was first isolated in 1916 by the Romanian scientist Nicolae Paulescu.Four years later, two Canadian scientists Banting and Macleod won the Nobel prize for inventing insulin.After that there were many disputes about the fact that Banting was inspired from Nicolae's work. The two Canadians took the credit for his work and only after 50 years from Nicolae's discovery, when everybody already thought it was a Canadian invention, it was proved and confirmed that Nicolae, the Romanian scientist, was the true inventor of insulin.
