Refers to the differences between the Sciences and the Humanities as described in Charles Snow's famous lecture on The Two Cultures, presented at the University of Cambridge in 1959. For Snow, the industrialization was the only path to advancement by poor countries. That argument was not altogether new. In the Unites States, there had been occasions when the importance of the Sciences for the development of that country had been debated, and the relevance of the Humanities, as well, as the basis of forming productive thinking habits. Despite the marked differences between the various disciplines of the Sciences and between those and the Humanities, there are similarities in the methods of the Two Cultures. In History, for instance, scholarly communication practices approximate those in the Sciences. Recent research in Information Science in Brazil, looking at the current practices of historians of Colonial Brazil, show similarities to practices that until the 1980s were especially characteristic of the Natural Science, such as multiple authorship of articles, participation in collaborative projects, and the heavy use of technologies of information and communication There is evidence that nowadays the gap between the Sciences and the Humanities has become smaller. Snow’s ideas are a contribution to the History of Sciences and to Information Science, even though the Sciences have suffered major transformations due to the epistemic approximations proper of interdisciplinarity
