In Spain we have invented the mop. It’s a little painful but we can’t not clean the house without a mop.

It has invented in 1925. I don’t know if you use it in your country but in Spain we use it a lot.

I don’t want to use it but it’s necessary.

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.

Leonardo Torres Quevedo

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.
