In the 1590's, Galileo invented the thermometer. In 1609, Galileo perfected the astronomical telescope, improving upon the design of Hans Lippershey (which was imprecise and inverted the image). He also promulgated the theory that Earth and other planets in our solar system revolve around the Sun. This was supported by his discovery of moons around Jupiter, and his observations of the phases of the planet Venus (1610). Galileo conducted experiments with pendulums, establishing the relationships between length and period. He also applied these principles to gravity, determining that objects fall at the same speed regardless of their comparative masses. (This was the famous Leaning Tower expirement.)
