How did Galileo's inventions change the world?

Answer 1

He built his first telescope and started to make observations. He discovered the phases of Venus and sunspots. He built his first telescope in 1609. Galileo's taught mathematics and actually made a few discoveries in physics. When he heard about the inventor of the telescope and he wanted to improve it.

Answer 2

Galileo was not an inventor per se, though he did offer improvements to the design of the telescope. his improved telescope allowed him to see the 4 largest moons of Jupiter and over a series of nights he confirmed that they were definitely in orbit about Jupiter. this was the first observational evidence of bodies orbiting something other than the earth, disproving the geocentric model of the universe. building on this, he confirmed that Copernicus' heliocentric model reflected reality with observations of venus.

Answer 3

He described the phases of Venus, 4 of Jupiter's moons, observation of sunspots, and saw that there were jagged edges on the moon but realized there were only mountain tops! His observations led to a better understanding of the structure of the solar system.

Answer 4

Well, Galileo improved the telescope by playing around with two pieces of glass, which made the telescope. The telescope revised Copernicus' ideas by studying the heliocentric theory.
