Telescopes

When there was a magnifying glass, people, naturally, tried to use two instead of one glass to get even more magnification. Experimentally it was found that at a certain distance between the lenses, a remote object can be seen with a significant increase. This arrangement of lenses has served as the basis for creating the first telescope, which at the time was called a telescope. The invention of this device is sometimes attributed to the English philosopher and prirodata Roger bacon, who lived in the thirteenth century. Although perhaps the palm of victory belongs to the Arab scientists.
