中国古代神话里有一个“夸父追日”的故事。现在我们知道,夸父是不可能追上太阳的。不过我们可以讨论这样一个有趣的问题:假如夸父在地面上奔跑,他有没有可能看到太阳从西边升起,从东边落山呢?如果能看到这个反常现象,那么夸父应该在何时奔跑、向什么方向奔跑、以多大速度奔跑呢?下面让我们应用物理学和地理学的知识来解决这些问题。 In ancient Chinese mythology, there is a story of “Kawaii chasing the sun.” We now know that it is impossible to catch up with the Sun. However, we can discuss such an interesting question: If Kuafu is running on the ground, will he possibly see the sun rise from the west and fall from the east? If you can see this anomaly, then when should you boast? Run, run in what direction, run at what speed? Let’s use physics and geography to solve these problems.
