纳米技术:远远超乎想象 Nanotechnology:Beyond Your Wildest Dreams

Nanotechnology is the science of moving individual atoms around and putting them precisely where we want. Since everything is composed of atoms, by doing this we can, in theory, construct anything we want. For example, by moving around the atoms in a piece of coal, we could create a diamond.

纳米科技这门(新兴)科学,可以移动一个个原子,把它们精确地放到我们想放的位置。由于所有的物质都是由原子组成的,所以理论上,通过移动原子我们可以制造出任何想要的东西。例如,移动一块煤炭里面的原子可以制造出钻石。

Currently, nanotechnology is still quite crude. Scientists can alter the properties of things like plastics or cloth to make them harder or softer or more durable, but they can't build something new from a collection of atoms. Why? Well, because things are made up of billions of atoms and it takes too long to move them around.

目前的纳米科技还远未发展成熟。科学家可以改变某些如塑料、布料之类物品的特性,从而使它们变得或更硬或更软或更耐用,但是还不能用一堆原子制造出新的东西。为什么呢?因为物质是由数十亿个原子组成的,要移动这么多原子耗费的时间太长了。

So, the next big step in nanotechnology will be building machines that can do this automatically. Once we have these we should be able to make almost anything with no waste and no pollution, at very little cost. Scientists think that the first “Universal Assembler” might be built in around 15 years.

因此,纳米科技的下一步重大进展将是制造可自动移动原子的机器。一旦拥有了这种机器,我们也许就能制造任何东西,无废料、零污染,而且成本极低。科学家认为第一座“通用组合机”将在大约15年内完成。
