To create noblemen and kings While civilization has been improving our houses, it has not equally improved the men who are to inhabit them. It has created palaces, but it was not so easy to create noblemen and kings. Henry David Thoreau, Walden societycivilization
Can maintenance save civilisation? An Article by Tim Harford timharford.com Maintenance is a low-status affair: you can confess to being unable to change a tyre in a way that you would never confess to being unable to name a play by Shakespeare. …We understand the expertise of janitors, plumbers and mechanics, and we suffer mightily in their absence, yet somehow we take them for granted. We take for granted, too, the most basic maintenance of all — preparing food, washing clothes, changing dirty nappies. Nobody would boast at a dinner party or on a first date about doing any of this, yet it is essential. …This is about more than breaking bridges and breaking bike chains. There is a missed opportunity here to find something rather wonderful in maintenance. repaircivilization
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.
