Crucially, in Daniels' conception, invisible work had a physical and an emotional component.

至关重要的是，在丹尼尔斯的概念中，无形的工作有身体和情感的组成部分。

These everyday electric phenomena require physical components that manipulate charged particles in amazing ways.

这种日常的电气现象需要组件 物理学家可以控制带电粒子。

In order to find a fingerprint investigators will either use a physical component like a powder– So not cocoa powder?

为了找到指纹，调查人员要么使用粉末之类的物理成分——那么不是可可粉吗？

These everyday electric phenomena require physical components that manipulate charged particles in amazing ways. We make electrical components that excite millions of electrons in each pixel on this screen.

这些日常的电现象需要以惊人的方式操纵带电粒子的物理组件。我们制造的电气元件可以激发屏幕上每个像素中的数百万个电子。

So far, for most of this series, we've focused on hardware -- the physical components of computing -- things like: electricity and circuits, registers and RAM, ALUs and CPUs.

到目前为止，对于本系列的大部分内容，我们都专注于硬件——计算的物理组件——比如：电力和电路、寄存器和 RAM、ALU 和 CPU。
