  • Around the start of the 17th century, there was a famous manufacturer of optics, called Hans. One day, his disciple took a piece of freshly shaped concave lens and a convex lens to play, and when he put the two lenses together, he found that this can be used to view things from far by making them clearer, as though one was standing right in front of the object. things were magnified, they became bigger and cleaerer.
