Experimental science Upon hearing about this, Kepler urged Galileo to be more open about it politically and if need be move elsewhere if safety was a concern. Galileo Galilei pioneered the experimental scientific method, and was the first to use a refracting telescope to make important astronomical discoveries. Experimental science

He combined his experimental approach with his observational skills (e.g., viewing celestial bodies with his telescope) and with his theoretical and mathematical skills to produce revolutionary insights into the natural world.

Galileo's Big Mistake How and why the world's first modern scientist got it wrong about the tides The Father of modern science; expanded man's understanding of the Universe. In other words, except mechanics, astronomy, optics, music, statics, and hydrostatics, Galileo was *the very first* to take this step. Galileo was born in Pisa and his career coincided with that of Kepler. 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", inventing the thermoscope and various military compasses, and using the telescope for scientific observations of celestial objects.

Upon hearing about this, Kepler urged Galileo to be more open about it politically and if need be move elsewhere if safety was a concern. Students can type in their answers directly in the Google Slides. Galileo Galilei Italy Inducted in 1991. Galileo’s observations discredited the Aristotelian theory of an Earth-centered solar system in favor of the Copernican heliocentric model. This science article / sub plan comes in two versions with full answer keys: 1) Easily printable PDFs, as well as 2) Google Slides. In the 16th century, Polish astronomer Nicolaus Copernicus became the first scientist to promote a model of the solar system in which the Earth orbited its sun rather than the other way around.

Galileo's Big Mistake How and why the world's first modern scientist got it wrong about the tides Galileo was a great scientist and astronomer who developed modern astronomy.

Galileo's refractor and Newton's reflector remain the two standard types of optical telescopes today.

The work of Galileo is considered to be a significant break from that of Aristotle; in particular, Galileo placed emphasis on quantity, rather than quality. In the 16th century, Polish astronomer Nicolaus Copernicus became the first scientist to promote a model of the solar system in which the Earth orbited its sun rather than the other way around.
