摘要

The reductionist approach to science seeks to understand the behaviour of systems by studying their individual components.It has been an enormously productive approach,but it is also widely acknowledged now that in some systems the behaviour of interest is an emergent property that cannot be discerned in the separate parts.Biology is replete with such examples,from the flocking of birds to the way metabolic processes in cells rely on a dynamic interplay of proteins and other components.
