And that's somewhat inconvenient because we're working with wave functions, but it's a reality that comes out of quantum mechanics often, which is that we're describing a world that is so much different from the world that we observe on a day-to-day basis, that we're not always going to be able to make those one-to-one analogies.

这对于研究氢原子，很不方便,但这就是事实,而且在量子力学中经常会出现这种事实,那就是我们要描述的世界，和我们日常所看到的世界,之间的差别是如此之大,以至于我们不能，做出一一对应的类比,但幸运的是我们不用管。
