The document compares the campus of a university in 1970 and 1990. In 1970, the campus focused on traditional facilities like chemistry laboratories, mechanical engineering laboratories, and a main building. By 1990, the campus had expanded to include workshops on solar panels and local fruits, social outreach projects, robotics contests, and satellite campuses in other cities with facilities like business schools. The campus evolved from its original focus on traditional academics to also emphasize hands-on learning, community support, and new areas of study over the 20 year period.
