Isaac Newton, one of the greatest men in the history of science, was born in a little village in England in 1642. When Isaac was nineteen he became a student of Cambridge University. He began to study physics, astronomy and mathematics. Newton’s contribution to these sciences is so great that he may be considered the founder of modern mathematics, physics and spectroscopy. Newton discovered the law of motion and the universal law of gravitation. He studied the nature of light and colour and came to the conclusion that white light is composed of many different colours known to us as the spectrum. Such a phenomenon was quite unknown before Newton’s work. So long as humanity lives, Isaac Newton, the greatest of men of science, will never be forgotten.
