6.933J / STS.420J provides an integrated approach to engineering practice in the real world. Students of 6.933J / STS.420J research the life cycle of a major engineering project, new technology, or startup company from multiple perspectives: technical, economic, political, and cultural. Research involves interviewing inventors, reading laboratory notebooks, evaluating patents, and looking over the shoulders of engineers as they developed today's technologies. This subject is for students who recognize that technical proficiency alone is only part of the formula for success in technology.

Today many people assume that technological change is the major factor in historical change and that it tends to lead to historical progress. This class turns these assumptions into a question—what is the role of technology in history?—by focusing on four key historical transitions: the human revolution (the emergence of humans as a history-making species), the Neolithic Revolution (the emergence of agriculture-based civilizations); the great leap in productivity (also known as the industrial revolution), and the great acceleration that has come with the rise of human empire on the planet. These topics are studied through a mix of textbook reading (David Christian's "Maps of Time"), supplementary readings (ranging from Auel, "The Clan of the Cave Bear" to Hersey, "Hiroshima"), illustrated lectures, class discussions, guest lectures/discussions, short "problem paper" assignments, and a final project defined by the student.
Because MIT is celebrating its 150th anniversary in 2011, this version of the class will also focus on connections between MIT as an institution and technology in the history of the last 150 years.

Students are introduced to the engineering design process, focusing on the concept of brainstorming design alternatives. They learn that engineering is about designing creative ways to improve existing artifacts, technologies or processes, or developing new inventions that benefit society. Students come to realize that they can be engineers and use the design process themselves to create tomorrow's innovations.

Exploratory play is about asking questions: “What happens when I do this?” “What if I did it this way?” Experimenting with materials and pushing their limits encourages us to consider a wide range of possibilities when problem-solving. Playing around with objects and ideas helps us see that there may be more than one solution.

The airplanes unit begins with a lesson on how airplanes create lift, which involves a discussion of air pressure and how wings use Bernoulli's principle to change air pressure. Next, students explore the other three forces acting on airplanes thrust, weight and drag. Following these lessons, students learn how airplanes are controlled and use paper airplanes to demonstrate these principles. The final lessons addresses societal and technological impacts that airplanes have had on our world. Students learn about different kinds of airplanes and then design and build their own balsa wood airplanes based on what they have learned.
