    Discussion on the science-literature relationship and more

    I have long been gripped by an argument that I believe is profound, rooted in the science-literature dichotomy. It tends to favor one particular branch of knowledge, advocating an aut-aut (either pure science, or applied science) that devalues and demonizes the other. Unfortunately, in my...
