I love this weeks topic! I had loads of ideas popping into my mind [here you can see another one] when I read invention but I decided to go for this one: The telescope. It gave me the possibility to combine two things I like: watching stars all night long and history of science.
So, here he is, Galileo Galilei, seeing things noone has ever seen before him. He didn´t invent the telescope, though many people seem to think so. It was originally invented by Jan Lippershey in 1609 in Holland. Galilei only improved it. I read his biography last year and was captured by the thought what it´s gotta be like to see something so impressive first...and then being told that all that couldn´t be because one book says something different. But that´s another discussion.
I learned something from this, too: I need a tablet.
