I know that there are periods of history where most science and medicine was ill informed. When did non pseudo science, the seeds of our now massive scientific literature, begin-- and where?
There's not much in the FAQ about this - I should fix that! - but there are definitely some answers about the development of science on the subreddit. /u/restricteddata discusses the time period when science became seen as a distinct kind of study and answers 'when did science become Science?' and I discuss a similar question here in terms of Kuhn's delineation of experimental and mathematical sciences.
