Well this is coming from someone with limited knowledge about nanotechnology, although from what i've seen, heard, read, it seems like it provides a lot of small solutions? And when i say modern Engineering disciplines, i mean areas like electronics/electrical, mechanical, maybe civil? I've read about scientists creating transistors and such on the nano scale, so i'm wondering if they can do that, create all these minute nano stuff and modify them for the same purposes that large stuff now days does, then would nano technology replace the need for engineering?? I could have this completely wrong and interpret nano technology in another light, so i was just wondering? I don't know if this is valid 'evidence', but i've read how in some science fiction books, the authors use nano technology, how it has replaced the way conventional planes are built, where just nano structures control the flight and such...stuff like that.
