所以这个人，状态各种稳定，像我的锤子那样稳定，只有一个问题，那就是这人可能会，滑到绳子的两端去，这是很不幸的，当然。

再问个简单的问题：，加速度和绳子的张力，都是多少？
So now I could ask you a simple question: what is the acceleration and what is the tension in the string?
一条绳子的情况下没有问题。但是与狗不同（奥斯陶斯之前给狗做过实验），没有猫能够一直在两条平行的绳子里选择正确。
The single string test proved no problem, but unlike dogs (which Osthaus has previously tested) no cat consistently chose correctly between two parallel strings.
稍后我会，详细讨论失重的，在此之前，我先讲另一个问题-，如果挂在绳子上，如何测量重量？
I will return to this weightlessness very shortly in great detail but before I do that, - I would like to address the issue — how could I determine your weight if I hang you from a string?
那些卡片最经常被看作为起因(有很多绳子)最可能是问题的根源。

让我们来看“双线问题”：两根不同的绳子吊在天花板上。
Consider "the Two-String Problem". Two widely separated strings hang from a ceiling.
