Final answer:
Galileo Galilei is a central figure in the development of modern science, with major contributions to Astronomy and Physics. His inventions included the astronomical telescope, and he made discoveries that supported the heliocentric model of the solar system. Additionally, Galileo laid the groundwork for mechanics and the scientific method.
Step-by-step explanation:
Galileo Galilei is a central figure in the development of modern science. His contributions span various realms but particularly in Astronomy and Physics. Galileo is often credited with the creation of the modern astronomical telescope, ultimately leading to radical observations that supported the heliocentric model of the solar system, a model where the planets orbit the sun, contrary to the then-popular geocentric model, where the celestial bodies were believed to orbit Earth.
Unarguably one of his significant contributions to science was the discovery of Jupiter's moons and Venus' phases, which provided concrete evidence to support the heliocentric model. He contributed to the foundations of mechanics and the scientific method, emphasizing empirical observation and mathematical analysis.
