Learn to flex your mind for the good of all. Mentats are people from Frank Herbert's Dune mythology who have undergone training and developed their cognitive and analytical skills to staggering heights. Inspired by this ideal, Beginning Mentat Training is an idiosyncratic course on rationality, science and math, focusing on techniques that can be used in everyday life. Absolutely no background in technical fields required! Material will be presented in an engaging and practical form, focusing on core skills with broad applicability. Each class will consist of a lecture followed by discussion and practice; later classes will cover material chosen by students.
