摘要
如果我们把猫看成是一个受 T 不变力学支配的孤立的机械系统,那么它从静止状态释放后双脚着地的能力就是不可理解的。在这个框架内,我们可以为观察到的运动构建一个有用的信息。我们可以从这个例子中得到启发。
If we consider a cat to be an isolated mechanical system governed by
T-invariant mechanics, then its ability to land on its feet after being
released from rest is incomprehensible. It is more appropriate to treat the cat
as a creature that can change its shape in order to accomplish a purpose.
Within that framework we can construct a useful and informative of the observed
motion. One can learn from this example.
