Who was Galileo

Galileo was a famous philosopher, astronomer, and mathematician who made fundamental contributions to the sciences of motion, astronomy, and strength of materials and to the development of the scientific method. He was born on February 15, 1564 in Pisa, Italy. He is called the "father of observational astronomy", the "father of modern physics", the "father of the scientific method", and the "father of modern science".

Galileo studied speed and velocity, gravity and free fall, the principle of relativity, inertia, projectile motion and also worked in applied science and technology, describing the properties of pendulums and "hydrostatic balances". He invented the thermoscope and various military compasses, and used the telescope for scientific observations of celestial objects. His contributions to observational astronomy include telescopic confirmation of the phases of Venus, observation of the four largest satellites of Jupiter, observation of Saturn's rings, and analysis of sunspots.

Galileo performed a famous experiment. He climbed to the top of the Leaning Tower of Pisa From there, he dropped two iron balls, one much bigger than the other. Most people expected the bigger ball to land first, but they were wrong. As Galileo predicted, they landed at the same time. The people used to seeing lightweight objects falling slowly. Air resistance slowed them down, but very lithe air resistance acts on he iron ball, so balls of different sizes fall at the same rate.
