What Galileo invented?

Answer 1

Thermometer.

Various authors have credited the invention of the thermometer to Cornelius Drebbel, Robert Fludd, Galileo Galilei or Santorio Santorio. The thermometer was not a single invention, however, but a development.

Galileo Galilei also discovered that objects (glass spheres filled with aqueous alcohol) of slightly different densities would rise and fall, which is nowadays the principle of the Galileo thermometer (shown). Today such thermometers are calibrated to a temperature scale.

Answer 2

Galileo Galilei did not invent telescopes, but he did make significant improvements to them, which helped popularize their use in astronomy. He also made important astronomical discoveries, such as the moons of Jupiter and the phases of Venus. Additionally, Galileo was a key figure in the scientific revolution for his advocacy of the heliocentric model of the solar system.
