The dying art of the hatchet job An Article by Dorian Lynskey staging.unherd.com I find that the act of disagreeing with a sharp takedown sharpens my appreciation of the work in question. If I have to think a bit harder about what I like and why I like it, that’s fine by me, especially when it’s something that has been almost universally acclaimed. ...It’s not that I long for an epidemic of gleeful brutality but I will always cherish the right of critics to express their hate, hate, hate in the ultimate service of what they love, love, love. critique
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.
