Our modern world is built on a series of dependencies. In other words, many complex things in our technologically oriented society can exist only because a series of simpler inventions have been initiated successfully.

Consider, for example, the skyscraper - the very symbol of our large URBAN centers. Could such an EDIFICE exist solely as a huge monument of stone and metal soaring toward the heavens? Of course it couldn't. Many different factors come together to help make the modern skyscraper possible.

Think of the many things we might normally take for granted in such a place: electricity, heating, a system for bringing water to the higher floors of the building. These are only a few of the countless wonders of invention that combine to make possible a single complex entity such as a skyscraper. In thinking about the things that make a huge building possible, don't forget the invention of the elevator. How long would you last if you had to walk to your office on the 96th floor of the Empire State Building!
