ABOUT GLASS AND SEEING IMMENSELY
Glass has been one of the main essential actors of the great historical changes, thanks to this material mankind has been given a new perspective.
In 1608 the optician Hans Lippershey observed two children playing with some glass lenses in his shop. He noticed that combining two types of lenses, a concave lens used to correct myopia and a convex one used to correct pre presbyopia and hyperopia, and adjusting the curvature and the distance, it was possible to observe obects much closer. He then thought to place the two lenses in a tube, and created what he later called "Looker" or "Spectator", better known today as the telescope.
In the same period (1609) in Italy Galileo Galilei, being informed of the implementation of this instrument, decided to realize his own model he combined various curved lenses and created a telescope able to magnify objects up to thirty times. Thanks to this improvement men could finally turn their gaze towards what had always fascinated them the most: the Universe.
It was possible to observe the craters on the Moon and to understand that the planet Venus, having different diameters, had be located between the Earth and the Sun. Therefore our planet lost its "privileged position" and it was no longer the centre of the Solar system.
Space boundaries were no longer perceived as limits, in search of what gave rise to life, travelling in the interstellar space without moving from our planet, thanks to our curious eyes that go beyond the knowable.
All of this happened thanks to new tools that manage to revolutionize our lives, with a simple change in perspective.
