Today is the day that marks 400 years since the Italian physicist, mathematician and philosopher Galileo Galilei presented his telescope model, greatly improved to the already existent ones, to a few Venice merchants.
What’s interesting is that, although one can find multiple references regarding the fact that Galileo would be the inventor of the telescope, these are wrong. The patent’s owner for this invention is a Dutch (with german origin) by name Hans Lippershey, who, in turn, isn’t the real inventor himself.
The word “telescope” comes from Greek (tele = far, skopein = to see) and it was “invented” by Giovanni Demisiani, a mathematician, when Galileo showed his marvel at a banquet held by the italian Science Academy, in 1611. Galileo named his telescope with the Latin “perspicillum” (glasses) and used it to study the theories of Copernic regarding the movement of the planets.
The real invention of the telescope, is in fact the work of three people: Hans Lippershey and Zacharias Janssen, glasses manufacturers in Middelburg, and Jacob Metius from Alkmaar.
Galileo improved their invention in the next year, being one of the people that made possible the nowadays (earthbound and orbital) telescopes.

Si google a avut zilele astea pe pagina oficiala faza cu aniversarea lui galileo. Textul era format din niste mini-telescoape.
