If you turn on your TV today, you may see a commercial for ­Target in which the word "DESIGN," big and bold, flashes on a screen filled with oddly dressed people running around. "Is this a kind of madness?" you might ask yourself. But as the vibrant imagery on the TV ­settles in your mind, you are forced to conclude, "Ah, this is ... design."
If you are a trained technologist, you will quickly shake yourself out of your trance and contradict that notion. "No," you'll think. "Design is about efficiency, usability, and structural elegance." I have spent the majority of my adult life wondering about this fundamental question: what exactly is design?And I'm still asking.

Some languages have different words for the different ways we think about design. For instance, in Japanese there is the word sekkei, which connotes designing a mechanism, system, or technology with rationalized metrics for quality. Dezain, on the other hand, goes beyond an object's function to how it makes us feel. The former can be thought of as the kind of design taught at places like MIT; the latter as the kind of design taught at art school.
