For example, no matter how much a dancer wishes to leap off the floor and then start turning, the law of conservation of angularmomentum 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。

Somehow, it has the smell of some conservation of angularmomentum.
不知怎么的，这一定律和,角动量守恒定律有所相似。

The neutron stars rotate around, - we discussed that earlier-- - conservation of angularmomentum-- and they have strong magnetic fields.
