bAn introduction to computational thinking that traces a genealogy beginning centuries before the digital computer.bpA few decades into the digital era, scientists discovered that thinking in terms of computation made possible an entirely new way of organizing scientific investigation eventually, every field had a computational branch computational physics, computational biology, computational sociology. More recently, computational thinking has become part of the K-12 curriculum. But what is computational thinking This volume in the MIT Press Essential Knowledge series offers an accessible overview, tracing a genealogy that begins centuries before digital computers and portraying computational thinking as pioneers of computing have described it. ppThe authors explain that computational thinking CT is not a set of concepts for programming it is a way of thinking that is honed through practice the mental skills for designing computations to do jobs for us, and for explaining and interpr
