Twelve one-hour videos in the "Algorithmic Sustainable Design" series are accompanied by lecture notes on architecture and urbanism. Although the lecture notes can be read on their own, they are highly helpful for following the free online video course. Modern mathematical methods are used in this content to improve the architectural and urban design. The course material is unique and covers cutting-edge subjects for the first time in architecture and urbanism, including algorithms, fractals, cellular automata, complexity, emergence, information theory, symmetries, scaling, codes, and networks. The intellectual foundation of architecture is now accessible to students from throughout the world, who may use it to reestablish adaptability and true sustainability.
