The highest probability now is going to be along the x-axis, so that means we're going to have a positive wave function every place where x is positive.

概率最高的地方是沿着ｘ轴，这意味着只要在ｘ,大于零的地方波函数都是正的。

Another way to represent a point in a plane is I've got a radius and I've got an angle from the x-axis, right, and that's a standard thing you might do.

平面上面的点的方法,也就是极坐标,上面那种方法其实是，如果你们喜欢我这么说的话,笛卡尔坐标表示法。

We said, "Let's take, for the simplest case that we can possibly imagine, namely a particle moving in one dimension along the x-axis with a constant acceleration a.

我们说过,"考虑我们可以想象的最简单的情况,即质点在一维空间运动,沿着 x 轴且保持恒定加速度 a

That's a choice, and that choice turns out to be very interesting and really important, because if you connect these two points together, you get a straight line that has to intercept the x-axis at some point.

在这一选择下,我们会发现一件非常有趣，而且极其重要的事,当你把这两点用直线连接起来，你会发现这条直线,将与x轴在某点相交。

You cannot answer that, even if I promised to move only along the x-axis, because I think...I don't want to pose this as a question, because I think the answer is fairly obvious to everybody.

即使我保证只在 x 轴上移动,你们仍然无法回答,因为我觉得...我不想将其作为一个问题,因为我认为答案是显而易见的
