'Using cellphones since all they did was make calls... barely'

A telescope is an instrument designed for the observation of remote objects and the collection of electromagnetic radiation. The earliest known telescopes are credited to three individuals, Hans Lippershey and Zacharias Janssen, spectacle-makers in Middelburg, and Jacob Metius of Alkmaar also known as Jacob Adriaanszoon (see History of telescopes). "Telescope" (from the Greek tele = 'far' and skopein = 'to look or see'; teleskopos = 'far-seeing') was a name invented in 1611 by Prince Frederick Sesi while watching a presentation of Galileo Galilei's instrument, which was based on Hans Lippershey's design.. "Telescope" usually refers to optical telescopes, but there are telescopes that operate in other regions of the electromagnetic spectrum.
