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.
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.
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.
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.
thermometer, telescope and the inclined plane
Cause they changed the world of marine bioligy!
note pad in the shower
World War 1 happend
The first Inventions,Discoveries and Firsts of Hawaii was the Surfboard:)
the funky worm
thermometer, telescope and the inclined plane
how did his inventions change the world
pooop
he died
bib talk
telephone, telegram
Harvey Firestone Inventions change the world. he made tires so that means we got tires for cars so we can drive it change the world because now we can rive to different places i different countries or different state in or out of the USA
they allowed peolple to plow easier
it has let trains run automaticlly
because he thought that he could change the world with his inventions
he traveled to every plane t and saw aliens idiot
