Thus, it's also the art of getting the best results with the least energy possible.

因此，这也是用最少的能量获得最佳结果的艺术。

34. Which of the following uses the least energy?

34. 以下哪一项使用的能源最少？

Since the outermost electron has the highest energy, there's the least energy necessary to remove it.

由于最外层的电子具有最高的能量， 因此移除它所需的能量最少。

And the best theory is the most effective one, the one that can get to the destination the fastest while spending the least energy possible.

而最好的理论是最有效的理论，它能以最快的速度到达目的地，同时花费最少的精力。

Or in other words, if our process is a machine, the best one produces the greatest output for the least amount of input — the greatest results for the least energy.

或者换句话说，如果我们的过程是一台机器，最好的机器可以用最少的投入产出最多的东西——用最少的精力产出最多的东西。
