Microscopes

Microscopes trace their history back almost 1200 years with Abbas Ibn Firnas's corrective lenses. The first true microscope was made around 1595 in Middelburg, Holland. Three different eyeglass makers have been given credit for the invention: Hans Lippershey, Hans Janssen; and his son, Zacharias. The coining of the name "microscope" has been credited to Giovanni Faber, who gave that name to Galileo Galilei's compound microscope in 1625.
Microscopes are used to see microscopic things that are too small to see through a magnifying glass or by the naked eye.
