Isaac Newton Quotes
The smaller the planets are, they are, other things being equal, of so much the greater density; for so the powers of gravity on their several surfaces come nearer to equality. They are likewise, other things being equal, of the greater density, as they are nearer to the sun.
Newton, Isaac. The Mathematical Principles of Natural Philosophy. Translated by Andrew Motte, H.D. Symonds, 1803, Book III, Prop. VIII, Theorem VIII, Cor. 4, p. 193.
While critics of Islam cite this sura to show how absurd the Koran can be and contradicts what is known about the Earth’s orbit, few sophisticated, moderate Muslims believe this. However, even in the United States there are many Christians and Orthodox Jews who not only deny Evolution but also believe the Earth is 6000 years old. The basic difference is that in Islamic countries publicly critiquing such anti-scientific theological statements is rare and an individual who publicly argues against the Koran taken literally is often in danger from state or private retribution. In the West the conflict between the Bible and known science is not only publicly commented upon but in a somewhat derisive way. However, consider this: Islam is about 1500 years old. When Christianity was the same age, Galileo was tried and convicted by the Catholic Church for denying this very statement. Perhaps in another 700 years Muslims will look back with embarrassment on this as most of Christianity does.
The Roman Catholic Church had stultified scientific thinking for over a thousand years where differing with accepted church doctrine was not only discouraged but was dangerous. Hicletas—see {590328}—realized that the earth rotated around its own axis three centuries before Christ, and his view was in the literature to which learned people had access. Copernicus later communicated this idea to the Pope but in much more delicate terms—see {590327}. He did not have the problems that Galileo endured with the Church for several reasons. There were different men controlling the church, the printing press had been invented and Galileo published a book that many could read, the Protestant Reformation had really frightened the Church fathers who felt more vulnerable and less tolerant.
Sir Isaac Newton PRS was an English mathematician, physicist, astronomer, theologian, and author (described in his time as a "natural philosopher") who is widely recognised as one of the greatest mathematicians and most influential scientists of all time and as a key figure in the scientific revolution. His book Philosophiæ Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy), first published in 1687, established classical mechanics. Newton also made seminal contributions to optics, and shares credit with Gottfried Wilhelm Leibniz for developing the infinitesimal calculus.
