Brilliant course by the fine folks at the Santa Fe Institute. This excellent course by Dr. Melanie Mitchell is at once - fun, intriguing, thought-provoking, and gives one a great introduction to complexity sciences. Although she's written the definitive introductory book on the subject - the award-winning Complexity: A Guided Tour (https://www.amazon.com/Complexity-Guided-Tour-Melanie-Mitchell/dp/0199798109), this course stands on it's own merits with fun, engaging exercises in NetLogo. Highly recommended for anyone interested in math, science, and general knowledge for learning sake. Joe Domaleski, MBA, BS.
