The Towne Building, which is the main building of the School of Engineering and Applied Science, was built in 1903-06. Next to the Towne Building is the Moore School of Electrical Engineering, established in 1923. Between 1943-1946, ENIAC (Electrical Numeric Integrator and Computer), the world's first all-electronic, large scale, digital computer was created here. Today, the Towne Building and its adjacent buildings house the School of Engineering and Applied Science, a machine shop, library, mainframe and auxiliary computer labs, and student laboratories. A state-of-the-art wind tunnel is also available for experimentation. Every two years, engineering students design and build a solar car, which races against entries from 50 other colleges. About 50 students participate in this project, for fun or as part of their senior design project.
