Joan Roget

Joan Roget was born in Girona at the sixteenth century. Recent studies suggest that could have a crucial role in the invention of the telescope.Generally credited with the invention of the telescope to Hans Lippershey, a German manufacturer of lenses, but recent research from the British Magazine “History Today”attributed the authorship to John Roget in 1590.

Here is one of our most important inventors, Leonardo Torres Quevedo, was the father of digital computers (and many other digital devices, almost magical at the time, as the laser pointer or typewriter Torres-Quevedo). Calculations performed independently (some of them quite complex). All scientific calculators down after the invention of Torres Quevedo, one of the great spanish mathematicians.
