As soon as I detect with what we'll call a condition if I'm touching the edge I have to essentially spin around 180 degrees and then continue looping.
一旦我检测到这种情况,当我碰到边界时,我需要转180°然后继续这一循环过程。
But the reason that I like that analogy is that it points out a very important part of spin, and that's the idea that it's a description of the electron.
但我喜欢这个类比的原因是因为,它指出了自旋非常重要的一面,那就是它是一种电子的描述。
Then they said, I'm going to ask you a question but before you answer the question I'm going to spin a wheel of fortune.
他们说,接下来我要问一个问题,但是在你们回答之前,我会转幸运轮盘
