With generous funds from Princeton’s Dean of the College, in January 2016 we launched a massively open online course (MOOC) based on the bridges lectures of CEE262. The series consists of an Introduction lecture plus 8 more lectures that illustrate the art of engineering design as it relates to some of the worlds most significant bridges. More information can be found here. The class enrolled over 10,000 students representing 178 countries. Two new similar MOOCS are in development: one on buildings and another on vaults.
