Galileo Galilei, the “Father” of modern science, was born in Pisa, Italy. For nearly twenty years, he was a mathematics professor at the University of Padua, where he worked on many experiments, mainly in the fields of physics. In 1609, he found out about a telescope in Holland, and without having seen it, he created his own version, with which he made many astronomical discoveries. Galileo was accused for supporting the revolutionary -at the time- Copernican Theory, which said that the sun was the center of the solar system. Due to his provocative ideas, he was banned from teaching and sentenced to house arrest, where he continued to write until his last days.
