高中物理的绪论课上,在介绍物质的研究对象时,经常会使用这幅彩图(图1),图中的蛇形象非常奇怪,蛇头咬住蛇尾,人们称之为“衔尾蛇”。衔尾蛇,作为世界上最为古老的神话符号之一,在不同的文明中有不同的象征意义。而在物理学中,这条蛇则形象地表示了物理规律的普遍性和研究对象:物质空间尺寸的层次,蛇头和蛇尾分别代表物质形态的两种极限——宇宙学与粒子物理学。随着现代物理的发展,我们了解到宇宙学问题的解决依赖于粒子物理的发展,而宇宙又是粒子物理的天然实验室,它们的关系亦如这条蜷缩成圆形的蛇,本文试图从物理学的角度来认识这条巨蟒。
High school physics introductory class, the introduction of the material object of study, often use this color map (Figure 1), the snake image is very strange, the snake head bites the tail, people call it ". The rattlesnake, as one of the oldest mythological symbols in the world, has different symbolic meanings in different civilizations. In physics, however, the snake vividly expresses the universality of the laws of physics and the object of study: the level of physical space, and the snakeheads and the constellations represent the two limits of material form - cosmology and particle physics respectively. With the development of modern physics, we have learned that the solution to cosmological problems depends on the development of particle physics, which is also a natural laboratory for particle physics. Their relationship is also like that of a snake curled up into a circle, Physics to understand this python.
