Which person did which? Read and write A for Galileo Galilei and B for Neil Armstrong. A. Galileo Galilei was an Italian astronomer, physicist and engineer from Pisa. Galileo has been called the father of observational astronomy and modern physics. During his time, scientists weren't really "scientists". People studied the works of the classical philosophers and thinkers such as Aristotle. They didn't run experiments and just believed them to be true. Galileo had different ideas. He wanted to test the principals and see them in the real world. This was a new concept to the people of his time and laid the foundation for the scientific method. In 1609, Galileo heard of an invention from Holland called the telescope that could make far away items appear much closer. He decided to build his own telescope. He made great improvements to the telescope and began to use it to view the planets. Soon Galileo's version of the telescope was used throughout Europe. As Galileo studied the planets and the Sun, he became convinced that the Earth and the other planets orbited the Sun. B. Neil Alden Armstrong (August 5, 1930 – August 25, 2012) was an American astronaut and aeronautical engineer, and the first person to walk on the Moon. He was also a naval aviator, test pilot, and university professor. On July 20, 1969, Armstrong and Apollo 11 Lunar Module (LM) pilot Buzz Aldrin became the first people to land on the Moon. He and Aldrin walked around for three hours. They did experiments. They picked up bits of moon dirt and rocks. They put a U.S. flag on the moon. They also left a sign on the moon. After he resigned from NASA in 1971, Armstrong taught in the Department of Aerospace Engineering at the University of Cincinnati until 1979. He served on the Apollo 13 accident investigation and on the Rogers Commission. 1. This person made great improvements to one invention. 2. This person investigated a space accident. 3.
