Explanation: Planets. He lived from 1473 – 1543, yet his calculations (as shown by the table below) compared to modern calculations show how advanced he was in his observations and mathematical genius.

After beginning training for a medical career, ______________ found that he had little interest in the subject and later switched to mathematics. Explanation: Galileo. His refusal to accept dogmatic statements without proof allowed his mathematic abilities to proliferate. In 1589, he became professor of mathematics and astronomy at the university at Pisa. Galileo's greatest contributions were in the field of ______________. Detailed Explanation: Mechanics. Galileo experimented with pendulums, with balls rolling down inclined planes, with light and mirrors, with falling bodies, and many other objects. Galileo showed that if a heavy and light object were dropped together, even from a great height, both would hit the ground at practically the same time. Galileo has often been called the ___________ of modern astronomy. Explanation: Father. Galileo probably has been the person most widely recognized as the "father of modern astronomy", although there are many historians that have given the title to Nicholas Copernicus or Johannes Kepler. The actual first telescope that attracted much notice was built by the Dutch spectacle maker ______ _____________ in 1608, but was only about three power. anation: Hans Lippershey. Historians generally credit Lippershey with the invention of the telescope, as he was the first to apply for a patent for a design. There is uncertainty about whether others had built telescopes earlier in the past. Lippershey's telescope was a simple refracting telescope which involved two lenses: Galileo was the first known astronomer to build a telescope for the specific purpose of observing and recording celestial bodies. His telescope was about __________ power. Detailed Explanation: Thirty. Hans Lippershey invented the telescope in 1608, intending it for use as a military device. Having heard of the discovery of Hans Lippershey, it was in 1609 that Galileo constructed a much improved refracting telescope of his own. He is the first person credited with using the telescope for looking at the stars. With the aid of his telescope, he was able to make keen observations that were recorded in his book Message from the Stars. It was Isaac ____________ who formulated the basic laws of modern mechanics and showed them to be universal throughout the solar system, applying to the motions of the celestial objects as well as to objects on the Earth. Detailed Explanation: Newton. His greatest contributions in the fields of astronomy, mechanics, optics, and mathematics were conceived by the time he had reached the age of 24.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
