As the significance of quantitative functions of technologies, whether or not they are culturally explicit or not, happens to be clearer, there are already growing attempts to obtain these facts by field employees considering economic anthropology, cultural ecology, nourishment, housing, usage, and compact-scale sector, and by learners with the prehistory and background of technology.
