The close Think of it as an invisible geometric shape perceptible only to lawyers—a conceptual pane of glass that might not have kept the rain out but could, for legal purposes, be used to define the original limits of the car’s interior. This is the close, and defining it is ultimately just a form of connecting the dots: drawing an imaginary line from the corner of an open window to the edge of a nearby wall to the front gate of a home garden, and so on. Breaking the close thus constitutes entry into a “protected interior” or “specified enclosure". Geoff Manaugh, A Burglar's Guide to the City law

Materials and how to employ them Forming a paper clip presents a common dilemma encountered by engineers and inventors: the very properties of the material that make it possible to be shaped into a useful object also limit its use. If one were to try and make a paper clip out of wire that stayed bent too easily, it would have little spring and not hold papers very tightly. On the other hand, if one were to use wire that did not stay bent, then the clip could not even be formed. Thus, understanding the fundamental behavior of materials and how to employ them to advantage is often a principle reason that something as seemingly simple as a paper clip cannot be developed sooner than it is.
