There are six basic types of simple machines, starting with the inclined plane.

简单机器有六种基本类型，先从斜面开始介绍。

The wedge is a simple machine that's been used since prehistoric times.

楔子是一种简单机器，从史前时代就开始使用了。

It's easy to see why you might think that sort of thing when you stick to simple machines.

你对于简单机器抱有这种想法是很自然的事。

Froghoppers, and their cousins planthoppers and leafhoppers, do this using an incredibly cool simple machine that is built in their bodies.

沫蝉，以及它们的表亲飞虱和叶蝉，使用一种非常酷的简单机器来做到这一点，这种机器是在它们的身体里建造的。

What makes these tiny animals so cool is that they've developed simple machines–latches and springs–thanks to nothing more than the power of evolution.

这些小动物之所以如此酷，是因为它们进化出了简单的机器——闩锁和弹簧——这完全归功于进化的力量。

Well, cheering shows that this simple hypothetical machine can perform any computation, if given enough time and memory.

好吧，欢呼表明，如果有足够的时间和内存，这个简单的假设机器可以执行任何计算。

I'm not an engineer, but the fact that they have simple machines: latches, levers, and springs, built into their bodies, blows me away.

我不是工程师，但是它们有简单的机器：闩锁、杠杆和弹簧，内置在它们的身体里，这一事实让我大吃一惊。

Psychologists put people in this simple machine where you push a button and it makes a light go on.

心理学家把人放在这个简单的机器里，你按下一个按钮，它就会点亮灯。

With billions of transistors in just your smartphones, computers can seem pretty complicated, but really, they're just simple machines that perform complex actions through many layers of abstraction.

如果只看你手机中那数十亿晶体管的话，计算机可能看起来会相当复杂，但是讲真，它们只是通过许多层的抽象结构表现复杂行为的简单机器。

Holmes also needed-or at least would very much have appreciated, sophisticated gadgetry of a sort that could make very fine measurements from tiny samples, and as we have seen it was all he could do to get a simple adding machine.

霍姆斯还需要──至少会很高兴拥有：一种能对细小样品进行精密测量的先进仪器，而我们已经知道，他所能得到的不过是一台简单的加法机。
