Foreward Understanding Nanotechnology Michael L Roukes For every biological entity from the smallest virus or bacterium to the largest of mammals there exists a genome containing the information that specifies a complete blueprint for that species These are information packages of almost inconceivable complexity encoded in molecular detail They in turn provide the instructions enabling cellular machinery to assemble with atomic precision the variety of proteins endowing biological entities with their viability which is manifested in a myriad of forms Stepping back from the perspective of things molecular to those global it is obvious that within our biosphere at each and every moment this kind of mass production with atomic specificity is ongoing with astronomical multiplicity This nature s awe inspiring nanotechnology her machinery is already and always in motion From my perspective as a nanoscientist over the pat two decades this sets what seems today almost an unattainable challenge for us Yet we press on in our labs undaunted Collectively pursuing what is the overarching goal in our field namely engineering assembly then mass production of matter and machines with atomic precision But if truth be told nanotechnology apart from nature s realization is still at present largely a vision for the future But here vision and imagination are all important in fact there is ample room for scientific visionaries to coexist symbiotically with the futurists who fascinate and sometimes pro us with exotic dreams of worlds to come Ultimately however all of our fanciful notions must be subjected to the refinement and distillation of true laboratory science These shortcuts generally do not exist concrete bridges to new understanding must always emerge from a base of reproducible and verifiable scientific fact Ultimately progress in science and engineering hinges upon connections that carry us from the knowledge of today to the breakthroughs of tomorrow Historically such advances
