Nanotechnology: What’s in a name? Part 1
Correction: It appears the term “nanotechnology” was first used by Norio Taniguchi in 1974, not Eric Drexler. However, Drexler certainly popularised the use of the word.
The soft machines blog this week brings up an old debate between opposing views of nanotechnology. To summarize, there is a small but influential number of scientists who believe that the true potential of nanotechnology lies in ultra miniaturisation of everyday manufacturing capabilities. For example, individual atoms or molecules moved and an assembled to build fantastic new materials and machines (known as molecular manufacturing).
This view was originally championed by Eric Drexler in his book Engines of Creation in the mid 80’s, where he coined the term nanotechnology to describe his ideas. The opposing view is that the properties of materials on the nanoscale, and the way these properties can be tuned for industrial applications, are of huge scientific interest and more immediate technological importance. The majority of nanoscience research falls into the second category, and many are skeptical about whether the first is even possible.
Both camps use the term nanotechnology, but they describe rather different things. The molecular manufacturing lobby argue that the term has been misappropriated by scientists in other fields, jumping onto the nanotech funding bandwagon and diverting money from molecular manufacturing research.
There are technical arguments between the two groups, which I’ll come to another time, but for now I’m interested in public perception. It’s impossible to enforce restrictions on the use of the term now. No matter how the word nanotechnology is defined in legal or technical terms, people will understand and use it in different ways; it’s the nature of language that no one person owns the word.
Isn’t it important, given the public and political interest in nanotechnology, that we know what we’re talking about?
