# His Scientific work with Roger Penrose on Gravitational Singularity and the framework of the General Relativity.
# He often predicted that “Black Holes” emit radiations, later called “Hawking Radiation”.
# He is the member of the FRS (Fellow of Royal Society), Lucasian Professor of Mathematics at University of Cambridge (1979-2009).

# Galileo Galilei was born on 15 February, 1594 and consider the “Father of Observatory Astronomy”.
# He was Mathematician, Philosopher, Engineer, Astronomer, Physicist and Italian Polymath.
# He studied on Principle of Relativity, Motion, Speed and Velocity, Free Fall, Inertia and Projectile Motion.
# He was the first who discovered the four largest satellites of Jupiter.
# He was the master of “Heliocentrism” and believed earth revolve around the sun and all other planets also revolve around the sun not the earth. But most people believed on Aristotelian Geocentric as all heavenly bodies revolve around the earth leading Galileo facing a criticism against theory of “Geocentric”.
