A Biography of Galileo Galilei

There have been many frontiers throughout the history of the world. There have been huge accomplishments, especially in the field of science. Yet, none have even come close to the amazing accomplishments of Galileo Galilei. Galileo provided a frontier in history because of his improvements in the field of science, his discoveries, his many inventions, and his intelligent theories. Galileo was not very supported by anyone when he started, but he soon began gaining popularity as he ascertained different things and started proving that he was right and some ideas of the past were erroneous.

In the summer of 1609, Galileo’s inspiration of improving the telescope was launched. A friend of his, Paolo Spari of Venice, wrote to him, asking him to try and figure out how the invention of the spyglass worked (MacLachlan 46). In his letter, he wrote that Lippershey of Holland had discovered that two lenses, if placed if front of one another, would enable great distances to be seen three to four times closer than usual, but they would only be able to be seen upside down (Levinger 75). Galileo accepted the challenge immediately after he read the note, attempting to discover the principle behind the spyglass, reproduce it, and then finally improve it (Rosen 119). Galileo soon discovered that light rays from the object go through the converging lens and eyepiece at the end of the tube, enabling him to create his own spyglass (Bernadini 49). The model of the new and improved “spyglass” took less than a day to create (Rosen 120). However, the actual “spyglass” took much longer to construct (Rosen 121).
