The social sciences,in studying subjective, inter-subjective and objective or structural aspects of society, were traditionally referred to as soft sciences. This is in contrast to hard sciences, such as the natural science, which may focus exclusively on objective aspects of nature.
Industrial archaeology, like other branches of archaeology, is the study of material culture from the past, but with a focus on industry. Strictly speaking, industrial archaeology includes sites from the earliest times (such as prehistoric copper mining in the British Peak District) to the most recent (such as coal mining sites in the UK closed in the 1980s).
