Galileo di Vincenzo Bonaiuti de' Galilei, known just as Galileo, was an astronomer, physicist, and engineer from Pisa, modern-day Italy, who was regularly described as a polymath. Galileo has been called the "creator of observational astronomy," "father of modern-day physics," "father of the clinical technique," and "father of contemporary science," to name a few titles.Galileo engaged on useful science and innovation, clarifying the characteristics of pendulums and "hydrostatic balances," and also studying speed and speed, gravity and free fall, the concept of relativity, inertia, and projectile movement. He created the thermoscope and some army compasses, and he used the telescope to observe celestial things clinically. Telescopic verification of Venus' stages, observation of Jupiter's 4 biggest satellites, research study of Saturn's rings, and analysis of sunspots are amongst his contributions to observational astronomy.Galileo's big testimony and support of Copernican heliocentrism (the Earth turning daily and circling the sun) drew criticism from the Catholic Church and certain astronomers. In 1615, the Roman Inquisition checked out the subject and realized that heliocentrism was silly, absurd, and profane because it went against the Holy Bible.No doubt Galileo was an intelligent person, who paved the way for many discoveries and inventions. Let's take a look at his life, his mission, and his accomplishments.
