Galileo Inventions Facts for Kids Video
Galileo Galilei was an Italian astronomer who invented various mechanical devices. The telescope was one of the most famous of Galileo’s inventions. He made the very first telescope in 1609 which was modeled after many previous telescopes produced other parts of Europe. Galileo’s telescope was one of the central instruments of the scientific revolution of the 17th century. It was the prototype of the modern day refractor telescope. Basically, it was a simple arrangement of lenses that started with fixing optician’s glass on either end of a hollow cylinder. In the telescope, the objective lens was convex and the eye lens was concave.
