Engineering is about extending the horizons of society by solving technical problems, ranging from the meeting of basic human needs for food and shelter to the generation of wealth by trade. This free course, Engineering: The challenge of temperature, looks at the impact of changes in temperature on a variety of objects and looks at the problem of how to boil water.
