Who the problems are Recently my attention was drawn to a quote from Peter Drucker who said, "If there isn't dissent, we would not know where the problems are." I said to my husband, "Look, if there isn't dissent, we wouldn't know who the problems are." I think one has to keep that in mind. Peter F. Drucker, Every Tool Shapes the Task argument

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.
