Confronted with the accelerated development of science and technology the presented analyses are focusing on three predominant theoretical approaches in the philosophy of science and technology: technoscience (STS), technology assessment (TA) and converging technologies (NBIC). On this base are extrapolated the coordinates of the heuristics of technosciences which are recognized as the platform of understanding but also dealing with technoscientific innovations. This concerns especially nanotechnology and the emerging theoretical, methodological, ethical, socio-political controversies and dilemmas. In this manner the book epitomizes the elaborated to date approaches and designs the heuristic turn as the strategy of comprehensive understanding of technosciences.
