For example, no matter how much a dancer wishes to leap off the floor and then start turning, the law of conservation of angular momentum absolutely prevents such a movement.(例如，无论一个舞者多么想要跳离地板，然后开始旋转，角动量守恒定律绝对阻止这样的动作。)
It describes the angular momentum of the electron.(它描述的是，电子的叫角动量。)
That is the angular frequency.(这是角频率。)
Why should I join the straying mass who want to make everything angular?(为什么我要加入那些想要把一切都变得棱角分明的走失群体?)
Angular momentum is in this direction.(角动量是这个方向了。)
So it has a phenomenal angular velocity.(它有个明显的角速度。)
I am the spin angular momentum.(我就是旋转的角动量。)
What will the angular...(角动量。)
Actually, we are rotating at unit angular speed.(实际上，是以单位角度旋转。)
What will the spin angular momentum do?(旋转的角动量会怎样呢？)
