望远镜是一种能把远方景物的距离拉近或变大的镜片组合。这在当初许多人认为是不可思议的,甚至是不能实现的。虽然望远镜的发明是偶然的事,但从科技发展水平来看实属必然,因为当时的技术和材料已具备了发明望远镜的条件。
A telescope is a combination of lenses that can bring the distance of a distant object closer or larger. This was originally thought by many people to be unthinkable or even impossible to achieve. Although the invention of the telescope was accidental, it was inevitable from the perspective of the level of scientific and technological development because the technology and materials at that time already had the conditions for inventing the telescope.
