电子墨水的速度问题意味着它也无法播放视频。

E Ink's speed problems mean that it can never display video, either.

物理学领域中，处理相对于光速的速度问题的就是所谓相对论。

The area of physics which deals with speeds comparable to the speed of light is called relativity.

But the problems can grow much faster than you can get a performance boost out of the computer.

对，电脑运行速度是很快,但是问题的规模增长的。

and we like log algorithms, because they're really fast. A typical characteristic of a log algorithm is a pro-- or sorry, an algorithm where it reduces the size of the problem by a constant factor.

并且我们也很喜欢对数算法,因为它很快,对数算法的典型特性是高速，哦，抱歉，是他能以常数因子的速度,降低问题的大小，很明显。

So, hopefully that kind of clears up that question. And, of course, when the velocity actually is zero, this equation that the de Broglie has put forth is valid for anything that has momentum, so if something does not have any velocity at all, it actually does not have momentum, so you can't apply that equation anyway.

能回答你的问题，当然，如果速度真的是零的话,德布罗意提出的这个方程,只对有动量的物体成立,所以如果一个东西没有速度，它没有动量，也就不能应用这个方程。
