And we'll make it a two-dimensional problem, because we have seen only one-dimensional problems now.

它是一个二维问题，因为我们已经发现，目前，它只是一维的。

Very similar to what I just did, but now it is a simpler problem, because a spring is exactly one-dimensional.

跟我刚才做的相似，但是问题更简单，因为弹力是，完全一维的。

And the one-dimensional problem indicates that the velocity that I'm dealing with is the component in this direction.

一问问题，表明我现在面临的，速度是，这个方向的因素。

The impressive cast features topnotch actors including Dianne Wiest, John Mahoney, Alison Pill, and Norbert Leo Butz who are limited by their one-dimensional roles, and Hedges offers disappointingly simplistic resolutions for every problem.
