"Pre–cooked foods, made possible by new packaging development, are a major time–saver for housewives. Notice the difference in time and effort required in the preparation of a pre–cooked, pre–packaged goulash dinner and one fixed entirely from scratch. lights attached to the cook's wrists show how many more movements she had to make in the 90 minutes it took the long way, compared with the pre–cooked way which took only 12 minute."

"Efficiency in human behavior is a goal that is rarely questioned in contemporary culture. This course will study and draw connections between disparate fields to trace the development and influence of this view. The course, drawing a mix of humanities and engineering students, will include readings and lectures on 19th and 20th century philosophers with discussions of new technology and team experimental projects.
Frederick Taylor, the father of industrial engineering, analyzed human motion to optimize industrial productivity, which had great influence on Henry Ford, military logistics, and Stalin. Michel Foucault traced the history of the minute analysis of human motion from Napoleon's methods for transforming peasants into soldiers to modern methods for reforming prisoners. Martin Heidegger claimed that 'efficient ordering' was the defining characteristic of modern culture. Through the course, students will learn to recognize how this obsession with efficiency for its own sake relates to technology and to their daily lives."
