My thanks to everyone who has contributed to this blog so far. Here, I would like to ask people a more specific question that follows on from David Bott’s post below. If you had a “matter compiler” – some device or scheme that could arrange atoms or molecules according to an arbitrary, user-defined blueprint – what would you do with it? What new materials would you make, what new devices do you think it would make possible?
I’ve given some of my own thoughts about this on a post on my own blog – It’s all about metamaterials – but what do you think? In the spirit of Jeremy Baumberg’s comment below, it would be interesting to hear thoughts not only about what might be possible in the future, but what we might aspire to on a much closer timescale, given the sort of limited capability we might hope to achieve in a year or two.
