From Stuff Matters by Mark Miodownik (pp. 80-81):
Given that literally half of the world’s structures are made from concrete, the upkeep of concrete structures represents a huge and growing effort. To make matters more difficult, many of these structures are in environments that we don’t want to have to revisit on a regular basis, such as the Oresund bridge connecting Sweden and Denmark, or the inner core of a nuclear power station. In these situations it would be ideal to find a way to allow concrete to look after itself, to engineer concrete to be self-healing. Such a concrete does now exist, and although it is in its infancy it has already been shown to work.
The story of these self-healing concretes started when scientists began to investigate the types of life forms that can survive extreme conditions. They found a type of bacterium that lives in the bottom of highly alkaline lakes formed by volcanic activity. These lakes have pH values of 9-11, which will cause burns to human skin. Previously it had been thought, not unreasonably, that no life could exist in these sulphurous ponds. But careful study revealed life to be much more tenacious than we thought. Alkaliphilic bacteria were found to be able to survive in these conditions. And it was discovered that one particular type called B. Pasteurii could excrete the mineral calcite, a constituent of concrete. These bacteria were also found to be extremely tough and able to survive dormant, encased in rock, for decades.
Self-healing concrete has these bacteria embedded inside it along with a form of starch, which acts as food for the bacteria. Under normal circumstances these bacteria remain dormant, encased by the calcium silicate hydrate fibrils. But if a crack forms, the bacteria are released from their bonds, and in the presence of water they wake up and start to look around for food. They find the starch that has been added to the concrete, and this allows them to grow and replicate. In the process they excrete the mineral calcite, a form of calcium carbonate. This calcite bonds to the concrete and starts to build up a mineral structure that spans the crack, stopping further growth of the crack and sealing it up.
It’s the sort of idea that might sound good in theory but never work in practice. But it does work. Research now shows that cracked concrete that has been prepared in this way can recover 90 per cent of its strength thanks to these bacteria. This self-healing concrete is now being developed for use in real engineering structures.
Maybe Miodownik is very good at explaining things, or maybe I am just ready to be learning this stuff. Probably both. I chose that excerpt because my average reader may not know about such things as bacteria which automatically repair concrete. But the truth is that I am almost embarrassed by how much I am reading that is new to me, or only vaguely known, as a sort of historical rumour.
I had no idea, to take just one example, who invented/discovered stainless steel, or where, or how. Now, I have a much better idea. The story is told on page 29 of this book, which I heartily recommend to all technological illiterates who would like not to be technological illiterates.
They were both as pristine and polished as life-size dolls recently removed from their cellophane boxes; rich-girl thin, almost hipless in their tight jeans, with tanned faces that had a waxy sheen especially noticeable on their foreheads, their long, gleaming dark manes with centre partings, the ends trimmed with spirit level exactitude.
I claim no expertise in the matter of the differences between male and female writers, but might not paragraphs like that have caused suspicions that “Robert Galbraith” was really a woman, even if the information had not been revealed on the front cover? It’s the detail. The waxy foreheads, the centre partings, trimmed like that. I don’t think a man would have gone into quite such detail, nor - in this age of male timidity about being anti-female – been as wonderfully rude about it.
I could be imagining all that. I don’t read much fiction by men either, and maybe the best men writers are just as exact about the women they describe and can be just as rude when doing it. And maybe most women writers would not refer to a spirit level in such a context. Really, I just liked it.
Quoted by “Robert Galbraith” (aka JK Rowling) at the beginning of The Cuckoo’s Calling:
Unhappy is he whose fame makes his misfortunes famous.
Celebrity and its discontents are nothing new.
Christopher Seaman, in his book Inside Conducting (pp. 89-90):
If you truly love a work, you’re bound to feel emotionally involved while you’re conducting it, and if this doesn’t get across to the musicians you’ll get a cold performance. Some conductors need to use bigger gestures than others to communicate with an orchestra. It takes great aptitude and long experience to pour your heart out yet still maintain the necessary composure. Professional musicians don’t need a good conductor to be over-demonstrative in order to pick up his musical ideas and feelings. I sometimes tell students who thrash around ineffectively with paroxysms of emotion that they’re meant to be cooking the music, not eating it. (The French term for conductor is chef d’orchestre, but that’s a coincidence.) James Levine is reputed to have said, “My tears only hurt my ability to make the audience cry.” And Richard Strauss said to Rudolf Schwarz, “Don’t sweat – let the orchestra sweat. Don’t weep – let the public weep!”
I came across an approving reference to the bit about “cooking the music, not eating it” in a review of this book in the BBC Music Magazine, November 2013 issue.
I do like how you can chase these things up properly nowadays.
… Yet for me, the most memorable 3D printing innovation of the last year or so was the launch of a $1,200 service called ‘Form of Angels’ from the Japanese pioneer Fasotec. Here an MRI scan is taken of a pregnant woman, and then used to produce a 3D printed model of her unborn baby. The plastic foetus can even be supplied embedded in a resin model of its mother’s midriff for presentation on the expectant parent’s mantelpiece.
Pictures of what that looks like here, among (as you can imagine) many other places.
From the Preface of Christopher Barnatt’s 3D Printing: The Next Industrial Revolution:
Within a decade or so, it is likely that a fair proportion of our new possessions will be printed on demand in a local factory, in a retail outlet, or on a personal 3D printer in our own home. Some objects may also be stored and transported in a digital format, before being retrieved from the Internet just as music, video and apps are downloaded today. While the required technology to allow this to happen is still in its infancy, 3D printing is developing very rapidly indeed. Some people may tell you that 3D printing is currently being overhyped and will have little impact on industrial practices and our personal lives. Yet these are the same kinds of individuals who once told us that the Internet was no more than a flash in the pan, that online shopping would have no impact on traditional retail, and that very few people would ever carry a phone in their pocket.
In 1939 the first TV sets to go on sale in the United States were showcased at the World Fair in New York. These early TVs cost between $200 and $600 (or about the same as an automobile), and had rather fuzzy, five inch, black-and-white screens. Most of those who attended the World Fair subsequently dismissed television as a fad that would never catch on. After all, how many people could reasonably be expected to spend a large proportion of their time staring at a tiny, flickering image?
The mistake made by those who dismissed television in 1939 was to judge a revolutionary technology on the basis of its earliest manifestation. Around 7S years later, those who claim 3D printing to be no more than hype are, I think, in danger of making exactly the same error.
I’m guessing that what I saw in Currys PC World, Tottenham Court Road, was the 3D Printer equivalent of those “rather fuzzy, five inch, black-and-white screens”, at the New York World Fair, the first stumbling steps.
I haven’t read much of this book yet, but I have already learned one excellent application of 3D printing, which is to print not the Thing itself, but the mold for making the Thing. You then make the Thing itself in the regular old way. Clever.
LATER: Here is Barnatt’s description of that last thing (p. 9):
A particularly promising application of 3D printing is in the direct production of molds, or else of master ‘patterns’ from which final molds can be taken. For example, as we shall see in the next chapter, ‘3D sand casting’ is increasingly being used to print molds into which molten metals are then directly poured to create final components. As explained by ExOne - a pioneer in the manufacture of 3D printers for this purpose - by 3D printing sand casting molds, total production time can be reduced by 70 per cent, with a greater accuracy achieved and more intricate molds created. In fact, using 3D sand casting, single part molds can be formed that would be impossible to make by packing sand around a pattern object that would then need to be removed before the mold was filled with molten metal.
Like I say, clever.
My scanner turned “molds” into “maids” throughout that piece of scanning. Not clever.
Alex Singleton has sent me an advance print-out of a book he has written about how to do PR. I have reached page 59, and am so far very impressed.
When I read a book of this sort, I like to read about relevant personal experiences, as well as Big Lessons and Grand Principles. That way, you are more likely to be convinced that the Big Lessons and Grand Principles really are as good and grand as they may merely seem.
So I particularly enjoyed this bit (from page 59):
When I got my first column in 1994, in a newsstand computer magazine, I had no idea what I was doing. But it seemed like I needed to get some stories, so I wrote to all the relevant companies and invited them to send me information about what they were doing. Not all of them replied - those that failed to respond were PR idiots. Some of them wrote to me saying that they would add me to their press release distribution lists - they were amateurs.
Then some guy called Quentin got in touch. His company, Accountz, sold products by mail order and it was miniscule - just him and his wife. But he wrote me a personal two-page letter (this was before email was commonplace) explaining how he had a Big Idea to defeat the major players in his sector. Unlike some of the other companies, he had no PR agency - but he had a story. And during the 15 issues I wrote that column, I could always rely on him
to take my calls and give me a good quote. When I upgraded to bigger-selling PC titles, including the market-leading ComputerActive, I kept on writing about his company. Today, his products are sold in PC World, Currys, AppleStores and Staples, and as I type this he has just made a successful exit from the company, passing it onto an investor.
What worked about that PR-journalist relationship is that Quentin - perhaps unwittingly - had good personal brand. He never tried to force a bad story on me and never wasted my time.
Alex has told me he is in the market for typos, and I think I see another blemish, to add to the two I’ve already told him about. Shouldn’t “onto” (final line of para 2 there) be “on to”? Not sure, but I think I’m right about that.
More about this book when I have finished it.
Incoming ("A quote you may like") from Richard Carey, who gave a great talk at my home last Friday, at my latest Last Friday, about The English Radicals at the time of the Civil War:
Here’s a quote from Algernon Sidney’s ‘Discourses on Government’, which lost him his head but gained him the admiration of Jefferson and others. Somewhere into the second paragraph, you will know why I have sent this!
The book is a riposte to one by a fellow named Filmer who wrote in support of the Divine Right of Kings, a notion Sidney found odious and false.
So, Richard having already supplied me with this excellent SQotD, penned by John Lilburne, we now have this:
Implicit Faith belongs to Fools, and Truth is comprehended by examining Principles
Whilst Filmer’s business is to overthrow liberty and truth, he, in his passage, modestly professeth not to meddle with mysteries of state, or arcana imperii. He renounces those inquiries through an implicit faith, which never enter’d into the head of any but fools, and such, as through a carelessness of the point in question, acted as if they were so. This is the foundation of the papal power, and it can stand no longer than those that compose the Roman church can be persuaded to submit their consciences to the word of the priests, and esteem themselves discharged from the necessity of searching the Scriptures in order to know whether the things that are told them are true or false. This may shew whether our author or those of Geneva do best agree with the Roman doctrine: But his instance is yet more sottish than his profession. An implicit faith, says he, is given to the meanest artificer. I wonder by whom! Who will wear a shoe that hurts him, because the shoe-maker tells him ’tis well made? or who will live in a house that yields no defence against the extremities of weather, because the mason or carpenter assures him ’tis a very good house? Such as have reason, understanding, or common sense, will, and ought to make use of it in those things that concern themselves and their posterity, and suspect the words of such as are interested in deceiving or persuading them not to see with their own eyes, that they may be more easily deceived. This rule obliges us so far to search into matters of state, as to examine the original principles of government in general, and of our own in particular. We cannot distinguish truth from falsehood, right from wrong, or know what obedience we owe to the magistrate, or what we may justly expect from him, unless we know what he is, why he is, and by whom he is made to be what he is. These perhaps may be called mysteries of state, and some would persuade us they are to be esteemed arcana; but whosoever confesses himself to be ignorant of them, must acknowledge that he is incapable of giving any judgment upon things relating to the superstructure, and in so doing evidently shews to others, that they ought not at all to hearken to what he says.
His argument to prove this is more admirable. If an implicit faith, says he, is given to the meanest artificer in his craft, much more to a prince in the profound secrets of government. But where is the consequence? If I trust to the judgment of an artificer, or one of a more ingenuous profession, ’tis not because he is of it, but because I am persuaded he does well understand it, and that he will be faithful to me in things relating to his art. I do not send for Lower or Micklethwait when I am sick, nor ask the advice of Mainard or Jones in a suit of law, because the first are physicians, and the other lawyers; but because I think them wise, learned, diligent, and faithful, there being a multitude of others who go under the same name, whose opinion I would never ask. Therefore if any conclusion can be drawn from thence in favour of princes, it must be of such as have all the qualities of ability and integrity, that should create this confidence in me; or it must be proved that all princes, in as much as they are princes, have such qualities. No general conclusion can be drawn from the first case, because it must depend upon the circumstances, which ought to be particularly proved: And if the other be asserted, I desire to know whether Caligula, Claudius, Nero, Vitellius, Domitian, Commodus, Heliogabalus, and others not unlike to them, had those admirable endowments, upon which an implicit faith ought to have been grounded; how they came by them; and whether we have any promise from God, that all princes should forever excel in those virtues, or whether we by experience find that they do so. If they are or have been wanting in any, the whole falls to the ground; for no man enjoys as a prince that which is not common to all princes: And if every prince have not wisdom to understand these profound secrets, integrity to direct him, according to what he knows to be good, and a sufficient measure of industry and valour to protect me, he is not the artificer, to whom the implicit faith is due. His eyes are as subject to dazzle as my own. But ’tis a shame to insist on such a point as this. We see princes of all sorts; they are born as other men: The vilest flatterer dares not deny that they are wise or foolish, good or bad, valiant or cowardly like other men: and the crown doth neither bestow extraordinary qualities, ripen such as are found in princes sooner than in the meanest, nor preserve them from the decays of age, sickness, or other accidents, to which all men are subject: And if the greatest king in the world fall into them, he is as incapable of that mysterious knowledge, and his judgment is as little to be relied on, as that of the poorest peasant.
My googling abilities are wayward, to put it politely, but based on a fleeting mention of a Micklethwait who was the grandson of “the physician”, the physician Micklethwait does appear to have been quite distinguished. And since he’s a Micklethwait, spelt Micklethwait (without, that is to say, any terminal e), that makes him a relative of mine, or so I have always assumed.
In the course of this googling for ancient Micklethwaits, I also came across this picture, which the National Portrait Gallery has in its collection, of my paternal grandfather, who was a lawyer. Hopefully the sort of lawyer whom Algernon Sidney would have been content to consult. Grandpa Micklethwait died when I was four and I think I must have met him, or at least been shown to him, but I have no recollection of this.
