What is 3 of Galileos discoveries or inventions?

Galileo discovered the four largest moons of Jupiter, now known as the Galilean moons. He invented an improved version of the telescope, which allowed him to make groundbreaking astronomical observations. Galileo formulated the principle of inertia, which laid the foundation for Isaac Newton's laws of motion.


What was Galileos mother ocupation?

Galileo's father, Vincenzo Galilei, was a lute player and music theorist. Galileo's mother, Giulia Ammannati, was the daughter of lumber merchant Cosimo Ammannati. She had no occupation. So she depended upon Galileo for her livelihood after her huband died in 1591.


How did Galileos observation of Jupiter and venus support Copernicus' model?

Galileo's discoveries with the telescope sowed doubts about the ancient Ptolemaic model which had the Earth at the centre. First, Jupiter's moons orbited round Jupiter and not the Earth, the first objects that had been discovered that were not orbiting the Earth. Secondly the discovery of the phases of Venus raised doubt about the Ptolemaic model, particularly the gibbous phase when, we now know, Venus is round behind the Sun as seen from Earth. In the Ptolemaic model Venus never goes behindthe Sun (as seen from Earth) and the gibbous phase cannot happen.By implying in the title of his book 'Dialogue of the two world systems' that there were only two models in contention, those of Ptolemy and Copernicus, Galielo insinuated that if the Ptolemaic model was incorrect the Copernican system must be correct. This was logically flawed because at the time there were two other systems in the public domain that both explained Venus's phases. These were the models of Tycho, which was geocentric, and finally Kepler's which was heliocentric.Of these four, Kepler's was eventually accepted by everyone after Newton's theoretical discoveries showed that Kepler's elliptical orbits for the planets agreed with the new theory of dynamics.


What did Galileo conclude from his observations of Jupiter and Venus?

how much more immature can yall be ?! seriously!! ppl look this stuff up to get help, immaturity is for facebook and high school the heavenly bodies were composed of material substance just like Earth, not pure orbs of light.
