The post 5½ Reasons to Ditch Spreadsheets for Data Science: Code is Poetry appeared first on The Lucid Manager. When I studied civil engineering some decades ago, we solved all our computing problems by writing code. Writing in BASIC or PASCAL, I could quickly perform fundamental engineering analysis, such as reinforced ...

Literature reviews are the cornerstone of science. Keeping abreast of developments within any given field of enquiry has become increasingly difficult given the enormous amounts of new research. Databases and search technology have made finding relevant literature easy but, keeping a coherent overview of the discourse within a field of ...
