telescope
The telescope is one of the most magnificent inventions made in the renaissance, first made by Hans Lippershey in 1608. Since this invention there have been plenty of astronomy lovers that have been trying to perfection it, for example Galileo Galilee. Since the fist invention of the telescope bye Hans Lippershey there have been many accusations that Lippershey stole the idea from another eye maker, Zacharias Jansen. Jansen is credited of inventing the compound microscope. Galileo is considered the first person to point the telescope skyward (nasa.gov). Even though Galileo’s perfection of the telescope was not perfect, he was able to see mountains and craters on the moon. Galileo Galilee nominated his telescope as a concave telescope, because it has a lens with inward curving surfaces.
Till 1611 Johannes Kepler switched the concave eyepiece to a convex eyepiece. This allowed the telescope to gain a much larger range of distance. (http://www.antiquetelescopes.org/history.html)It also allowed the projection of images on to a flat white screen. The only problem was that the images were upside down, Johannes Kepler added a third convex lens to make the images the right side way. Even though this was a great perfection od the telescope, recently the telescope that is mostly used is the one Galileo Galilee made, concave lens. For military projects is used the one from Johannes Kepler. Johannes Kepler studied the human eye and came to the conclusion that the wye lens is hyperbolodial, which means lenses are not too sharp because they smear the rays of light over a small area. But around 1637 Rene Descartes demonstrates that spherical lenses cannot produce pinpoints of light. He says that the combination of hyperboldial lenses or elliptical lenses will produce pinpoint of light and a greater image. This is an important topic that I am interested in sharing in he renaissance fair. I thinks its important because thanks to this marvelous
