During Renaissance, people received opportunity for freedom of expression by which in human mind a new perspective took birth to have the curiosity to know the mysteries of nature. In the 16th century, new scientific principles were established. 

These are as follows :

• Poland’s scientist Copernicus made the heliocentric principle of solar system by which it was proved that all heavenly bodies revolve around the sun. 
• German astronomer Johan Kepler verified Copernicus’ principles on the basis of mathematical proofs. 
• British scientist and mathematician, Issac Newton, established the principles of gravity. 
• French mathematician and philosopher, Descartes, applied trignometry in Geometry. 
• Italian scientist Galeleo invented the principle of Pendulum, air measuring instrument and telescope.
