Galileo galilei's contributions to modern science were so fundamental to a variety of fields that even though he died almost 400 years ago, his name retains international acclaim. This 17th-century natural philosopher is often credited with the invention of the telescope thanks to his many discoveries using that specific instrument, and though he was not, in fact, its inventor, the myth still persists. Indeed, galileo was responsible for a series of upgrades to astronomy's brand-new tool during the early part of the 1600s, and it was largely his innovative techniques that changed a somewhat mediocre magnifying glass into a revolutionary device.

In 1589, age 25, galileo was appointed to the chair of mathematics at the university of pisa, and made significant discoveries in both fundamental science, and applied science.
