Lectures and readings focus on bridges, railroads, power plants, steamboats, telegraph, automobiles, aircraft, computers, and the microchip. We study some of the most important engineering innovations since the Industrial Revolution. Most laboratory sections (Tuesday or Wednesday) focus on technical analysis of these major innovations. Experiments are modeled after those carried out by the innovators themselves. One laboratory section (Thursday 10 students max) involves replication and study of a historical engineering device or experiment for use in STEM education. The Thursday section is for students following Princeton's ProCES program.
