Predictive Maintenance Quotes

The TV scientist who mutters sadly, "The experiment is a failure; we have failed to achieve what we had hoped for," is suffering mainly from a bad script writer. An experiment is never a failure solely because it fails to achieve predicted results. An experiment is a failure only when it also fails adequately to test the hypothesis in question, when the data it produces don't prove anything one way or another.

An experiment is never a failure solely because it fails to achieve predicted results.

he predicted...that human slavery would come bac, that it had infact never gone away. he said that so many people wanted to come here because it was so easy to rob the poor people, who got absolutely no protection from the government. he talked about bridges falling down and water mains breaking because of no maintenance. he talked about oil spills and radioactive waste and poisoned aquifers and looted banks and liquidated corporations. "and nobody ever gets punished for anything," he said. "being an american means never having to say you're sorry.

He predicted, I remember, that human slavery would come back, that it had in fact never gone away. He said that so many people wanted to come here because it was so easy to rob the poor people, who got absolutely no protection from the Government. He talked about bridges falling down and water mains breaking because of no maintenance. He talked about oil spills and radioactive waste and poisoned aquifers and looted banks and liquidated corporations. “And nobody ever gets punished for anything,” he said. “Being an American means never having to say you’re sorry.

Part Three, that part of formal scientific method called experimentation, is sometimes thought of by romantics as all of science itself because that’s the only part with much visual surface. They see lots of test tubes and bizarre equipment and people running around making discoveries. They do not see the experiment as part of a larger intellectual process and so they often confuse experiments with demonstrations, which look the same. A man conducting a gee-whiz science show with fifty thousand dollars’ worth of Frankenstein equipment is not doing anything scientific if he knows beforehand what the results of his efforts are going to be. A motorcycle mechanic, on the other hand, who honks the horn to see if the battery works is informally conducting a true scientific experiment. He is testing a hypothesis by putting the question to nature. The TV scientist who mutters sadly, “The experiment is a failure; we have failed to achieve what we had hoped for,” is suffering mainly from a bad scriptwriter. An experiment is never a failure solely because it fails to achieve predicted results. An experiment is a failure only when it also fails adequately to test the hypothesis in question, when the data it produces don’t prove anything one way or another.

During periods of root expansion things have always looked as confused and topsy-turvy and purposeless as they do now. The whole Renaissance is supposed to have resulted from the topsy-turvy feeling caused by Columbus’ discovery of a new world. It just shook people up. The topsy-turviness of that time is recorded everywhere. There was nothing in the flat-earth views of the Old and New Testaments that predicted it. Yet people couldn’t deny it. The only way they could assimilate it was to abandon the entire medieval outlook and enter into a new expansion of reason.

The logical statements entered into the notebook are broken down into six categories: (1) statement of the problem, (2) hypotheses as to the cause of the problem, (3) experiments designed to test each hypothesis, (4) predicted results of the experiments, (5) observed results of the experiments and (6) conclusions from the results of the experiments. This is not different from the formal arrangement of many college and high-school lab notebooks but the purpose here is no longer just busywork. The purpose now is precise guidance of thoughts that will fail if they are not accurate. The

Certainly no one could have predicted what has happened. Back then, after 121 others had turned this book down, one lone editor offered a standard $3,000 advance. He said the book forced him to decide what he was in publishing for, and added that although this was almost certainly the last payment, I shouldn’t be discouraged. Money wasn’t the point with a book like this.

An experiment is never a failure solely because it fails to achieve predicted results.

In reality, electrons move in “probability clouds.” So what do you tell a sixth grader? Do you talk about the motion of planets, which is easy to understand and nudges you closer to the truth? Or do you talk about “probability clouds,” which are impossible to understand but accurate? The choice may seem to be a difficult one: (1) accuracy first, at the expense of accessibility; or (2) accessibility first, at the expense of accuracy. But in many circumstances this is a false choice for one compelling reason: If a message can’t be used to make predictions or decisions, it is without value, no matter how accurate or comprehensive it is. Herb Kelleher could tell a flight attendant that her goal is to “maximize shareholder value.” In some sense, this statement is more accurate and complete than that the goal is to be “THE low-fare airline.” After all, the proverb “THE low-fare airline” is clearly incomplete—Southwest could offer lower fares by eliminating aircraft maintenance, or by asking passengers to share napkins. Clearly, there are additional values (customer comfort, safety ratings) that refine Southwest’s core value of economy. The problem with “maximize shareholder value,” despite its accuracy, is that it doesn’t help the flight attendant decide whether to serve chicken salad. An accurate but useless idea is still useless.

Specialist or Strategist? Isn’t it true that the more you practice, the better you get? Yes, but, and this bears repeating, the intuitive mastery we are striving for is not brilliant skill at predictable tasks. As the late science fiction author, Robert Heinlein, pointed out, specialization is for insects. Humans need the mystifying ability to cope with the unpredictable and ambiguous challenges posed by thinking adversaries in the real world. Since kendo masters practice hard, don’t we need to put in long hours to develop super competence? The answer is absolutely yes. However, sixteen hours at the office doing the same things day after day simply make you a workaholic (and very likely a micromanager); they do not per se confer an intuitive skill useful in competitive situations. Tom Peters suggests that you can spot who is going to do great things by what they do on airplanes. They don’t pull out the laptop and grind spreadsheets. Instead, they “read Zen and the Art of Motorcycle Maintenance for the umpteenth time,” or pick up insights on human behavior from the great novelists.

Lenin, therefore, begins from the firm and definite principle that the State dies as soon as the socialization of the means of production is achieved and the exploiting class has consequently been suppressed. Yet, in the same pamphlet, he ends by justifying the preservation, even after the socialization of the means of production and, without any predictable end, of the dictatorship of a revolutionary faction over the rest of the people. The pamphlet, which makes continual reference to the experiences of the Commune, flatly contradicts the contemporary federalist and anti-authoritarian ideas that produced the Commune; and it is equally opposed to the optimistic forecasts of Marx and Engels. The reason for this is clear; Lenin had not forgotten that the Commune failed. As for the means of such a surprising demonstration, they were even more simple: with each new difficulty encountered by the revolution, the State as described by Marx is endowed with a supplementary prerogative. Ten pages farther on, without any kind of transition, Lenin in effect affirms that power is necessary to crush the resistance of the exploiters "and also to direct the great mass of the population, peasantry, lower middle classes, and semi-proletariat, in the management of the socialist economy." The shift here is undeniable; the provisional State of Marx and Engels is charged with a new mission, which risks prolonging its life indefinitely. Already we can perceive the contradiction of the Stalinist regime in conflict with its official philosophy. Either this regime has realized the classless socialist society, and the maintenance of a formidable apparatus of repression is not justified in Marxist terms, or it has not realized the classless society and has therefore proved that Marxist doctrine is erroneous and, in particular, that the socialization of the means of production does not mean the disappearance of classes. Confronted with its official doctrine, the regime is forced to choose: the doctrine is false, or the regime has betrayed it. In fact, together with Nechaiev and Tkachev, it is Lassalle, the inventor of State socialism, whom Lenin has caused to triumph in Russia, to the detriment of Marx. From this moment on, the history of the interior struggles of the party, from Lenin to Stalin, is summed up in the struggle between the workers' democracy and military and bureaucratic dictatorship; in other words, between justice and expediency.

Pratt & Whitney, the aerospace manufacturer, now can predict with 97% accuracy when an aircraft engine will need to have maintenance, conceivably helping it run its operations much more efficiently, says Anjul Bhambhri, VP of Big Data at IBM.

aim is to make the delivery of software from the hands of developers into production a reliable, predictable, visible, and largely automated process with well-understood, quantifiable risks. Using the approach that we describe in this book, it is possible to go from having an idea to delivering working code that implements it into production in a matter of minutes or hours, while at the same time improving the quality of the software thus delivered. The vast majority of the cost associated with delivering successful software is incurred after the first release. This is the cost of support, maintenance, adding new features, and fixing defects. This is especially true of software delivered via iterative processes, where the first release contains the minimum amount of functionality providing value to the customer. Hence the title of this book, Continuous Delivery, which is taken from the first principle of the Agile Manifesto: “Our highest priority is to satisfy the customer through early and continuous delivery of valuable software

(1) statement of the problem, (2) hypotheses as to the cause of the problem, (3) experiments designed to test each hypothesis, (4) predicted results of the experiments, (5) observed results of the experiments and (6) conclusions from the results of the experiments.

But I have been stressing that there are other underlying species-regularities involved. First, that women leaders do not inspire ‘followership’ chiefly because they are women and not only because of the consequences of those factors noted above ; secondly, even if they want to, women cannot become political leaders because males are strongly predisposed to form and maintain all-male groups, particularly when matters of moment for the community are involved. The suggestion is that a combination of these two factors has been the basis for the hostility and difficulty those females have faced who have aspired to political leadership. This has been the basis of the tradition of female non-involvement in high politics, and not the tradition itself. Cultural forms originally express the underlying ‘genetically programmed behavioural propensities’. In their turn, such cultural forms maintain – as tradition – an enduring solution to the recurrent problem of assigning of leadership and followership roles. In this connection, Margaret Mead writes about ‘zoomorphizing Man’. ‘Culture in the sense of man's species-characteristic method of meeting problems of maintenance, transformation, and transcendance of the past is an abstraction from our observations on particular cultures.’? This is then another way of looking at how broad political patterns may predictably emerge from the more detailed and programmed patterns of different behaviour of males and females. Some females may indeed penetrate some high councils. They become ministers of governments, ambassadors, and so on. A few may receive assignments which are not ‘feminine’ in their implication, such as Golda Meir, former Israeli Foreign Minister, and Barbara Castle, U.K. Secretary of Productivity and Employment. It is important to know what happens to the ‘backroom boys’ under such circumstances. Do they retire to an even more secluded chamber? Does the lady become ‘one of the boys’?

Everything we make will have predictive maintenance, improved efficiency, better safety, better usability. And everything will be made to order. We won’t be cranking out millions of identical widgets and stacking them up in pallets in overseas factories in order to be shipped around the world anymore. We’ll be customizing objects much closer to home. As Olivier Scalabre points out, we’ll be replacing the classic “East to West” trade flows with regional trade flows—East for East, West for West. “When you think about it, the old model was pretty much insane,” Scalabre says. “Piling up stock. Making products travel around the world. The new model—producing right next to the consumer market—will be much better for our environment. In mature economies, productivity will be back home, creating more employment, more productivity, and more growth.

People who live by the same code are rendered mutually predictable to one another. They act in keeping with each other's expectations because everyone knows what to expect from everyone else. A shared belief system, partly psychological, partly acted out, simplifies everyone—in their own eyes, and in the eyes of others. Shared beliefs simplify the world, as well, because people who know what to expect from one another can act together to tame the world. There is perhaps nothing more important than the maintenance of this organization—this simplification. If it's threatened, the great ship of state rocks.

Finally, we can contrast ‘resilience’ to ‘optimisation’ of the tax system. A key observation of resilience thinking is that fully optimising a system may make it less resilient. To achieve resilience, a system requires some redundancy, and this implies some multiplicity, inefficiency or overlap of methods or components. We should expect that we cannot fully optimise the tax system, in part because we cannot predict which elements may collapse or fail. Tax system maintenance is a dynamic and continual social and economic process – the maintenance of the tax state itself.

Well, I predict that if you think about it long enough you will find yourself going round and round and round and round until you finally reach only one possible, rational, intelligent conclusion. The law of gravity and gravity itself did not exist before Isaac Newton. No other conclusion makes sense. “And what that means,” I say before he can interrupt, “and what that means is that the law of gravity exists nowhere except in people’s heads! It’s a ghost! We are all of us very arrogant and conceited about running down other people’s ghosts but just as ignorant and barbaric and superstitious about our own.

Nothing about metabolism, however, is simple, and one last and important complication regarding efforts to walk off weight is a still poorly understood phenomenon known as metabolic compensation. Once again, studies of the Hadza play a role in how we understand this phenomenon. When Herman Pontzer and his colleagues measured daily energy expenditures in the Hadza, they were surprised to find that the highly active Hadza spend about the same total number of calories per day as sedentary industrialized people with the same lean body weight.44 In addition, when Pontzer and colleagues collected energetic data from adults in many countries including the United States, Ghana, Jamaica, and South Africa, they observed that more active people spent only slightly more calories per day than more sedentary people who weighed the same. In addition, individuals who were more physically active didn’t have total energy budgets as high as their exertions would predict.45 How could someone who spent five hundred extra calories a day exercising not have a total energy budget that is five hundred calories higher? The proposed explanation is that people’s total energy budgets are constrained: if I use five hundred extra calories walking, I’ll spend less energy on my resting metabolism to help pay for my exertions.46 This controversial idea (termed the constrained energy expenditure hypothesis) is still being tested, as is its relevance to weight loss. If correct, then contrary to many people’s expectations, exercisers might spend almost the same number of total calories per day as similar-sized but more sedentary individuals despite devoting more energy to being active. To appreciate the implications of this phenomenon, consider that the Hadza spend about 15 percent more of their total energy budget on activities like walking, digging, and carrying.47 In addition, as we will see later, exercise can stimulate repair and maintenance mechanisms that elevate people’s resting metabolic rates—an “afterburn”—for a few hours to as much as two days afterward.48 Yet if very active Hadza hunter-gatherers and exercising industrial people have total energy budgets that are about the same as similar-sized but physically inactive industrials, then they must spend less energy on other things like maintenance or reproduction. This may seem implausible, but we have already seen this phenomenon in people who lose a lot of weight, like the extreme dieters in the Minnesota Starvation Experiment whose resting metabolic rates plummeted.

Predictions are precarious. Still, so firmly has the Soviet political system been wedded to the policy of a high and growing rate of investment that at least this observer of its evolution has felt tempted to conclude that no other economic policy would be easily compatible with the maintenance of the Soviet dictatorship; in other words, that a policy of rapid increases of consumer`s welfare either would remain unacceptable to the dictators or, if accepted, would in all likelihood lead to the disintegration of the dictatorship. It matters little in this connection whether future history will verify or falsify this hypothesis. It is referred to here in order to throw into relief the antagonistic nature of the allegedly classless economy in which the investment interest of the government has been continually opposed by the consumption interest of the population.

Some of Becker’s most compelling research concerned altruism. He argued, for instance, that the same person who might be purely selfish in business could be exceedingly altruistic among people he knew—although, importantly (Becker is an economist, after all), he predicted that altruism even within a family would have a strategic element. Years later, the economists Doug Bernheim, Andrei Shleifer , and Larry Summers empirically demonstrated Becker’s point. Using data from a U.S. government longitudinal study, they showed that an elderly parent in a retirement home is more likely to be visited by his grown children if they are expecting a sizable inheritance. But wait, you say: maybe the offspring of wealthy families are simply more caring toward their elderly parents? A reasonable conjecture—in which case you’d expect an only child of wealthy parents to be especially dutiful. But the data show no increase in retirement-home visits if a wealthy family has only one grown child; there need to be at least two. This suggests that the visits increase because of competition between siblings for the parent’s estate. What might look like good old-fashioned intrafamilial altruism may be a sort of prepaid inheritance tax. Some governments, wise to the ways of the world, have gone so far as to legally require grown children to visit or support their aging moms and dads. In Singapore, the law is known as the Maintenance of Parents Act. Still, people appear to be extraordinarily altruistic, and not just within their own families.

People who live by the same code are rendered mutually predictable to one another. They act in keeping with each other’s expectations and desires. They can cooperate. They can even compete peacefully, because everyone knows what to expect from everyone else. A shared belief system, partly psychological, partly acted out, simplifies everyone—in their own eyes, and in the eyes of others. Shared beliefs simplify the world, as well, because people who know what to expect from one another can act together to tame the world. There is perhaps nothing more important than the maintenance of this organization—this simplification. If it’s threatened, the great ship of state rocks.

It isn’t precisely that people will fight for what they believe. They will fight, instead, to maintain the match between what they believe, what they expect, and what they desire. They will fight to maintain the match between what they expect and how everyone is acting. It is precisely the maintenance of that match that enables everyone to live together peacefully, predictably and productively. It reduces uncertainty and the chaotic mix of intolerable emotions that uncertainty inevitably produces.

The day after our wedding, we flew off on honeymoon. I had recklessly waited until two days before our wedding to book the holiday, in the hope that I would get some great last-minute deal somewhere. Always a dangerous tactic. I pretended to Shara that it was a surprise. But, predictably, those “great deals” were a bit thin on the ground that week. The best I could find was a one-star package holiday, at a resort near Cancun in Mexico. It was bliss being together, but there was no hiding the fact that the hotel sucked. We got put in a room right next to the sewer outlet--which gave us a cracking smell to enjoy every evening as we sat looking out at the…maintenance shed opposite. As lunch wasn’t included in the one-star package, we started stockpiling the breakfasts. A couple of rolls down the jersey sleeve, and a yogurt and banana in Shara’s handbag. Then back to the hammock for books, kissing, and another whiff of sewage. When we returned to the UK it was a freezing cold January day. Shara was tired, but we were both excited to get onto our nice, warm, centrally heated barge. It was to be our first night in our own home. I had asked Annabel, Shara’s sister, to put the heating on before we arrived, and some food in the fridge. She had done so perfectly. What she didn’t know, though, was that the boiler packed in soon after she left. By the time Shara and I made it to the quayside on the Thames, it was dark. Our breath was coming out as clouds of vapor in the freezing air. I picked Shara up and carried her up the steps onto the boat. We opened the door and looked at each other. Surprised. It was literally like stepping into a deep freeze. Old iron boats are like that in winter. The cold water around them means that, without heating, they are Baltically cold. We fumbled our way, still all wrapped up, into the bowels of the boat and the boiler room. Shara looked at me, then at the silent, cold boiler. No doubt she questioned how smart both choices had really been. So there we were. No money, and freezing cold--but happy and together. That night, all wrapped up in blankets, I made a simple promise to Shara: I would love her and look after her, every day of our life together--and along the way we would have one hell of an adventure. Little did either of us realize, but this was really just the beginning.

The sensory roles of the anulospiral receptor and the tendon organ are absolutely central in this process of exerting and adjusting muscle tone. These devices establish the “feel” for length and tension, and it is this feeling which is maintained by the gamma motor system, the reflex arcs, and the alpha skeletal muscles. All of my muscle cells—both alpha and gamma—are continually felt by the mind as they work, whether most of these “feelings” ever reach my conscious awareness or not. And it is primarily these muscular feelings which supply my central nervous system with the constant information necessary to successfully combine the demands of free motion with those of basic structural stability. The sophistication required for this maintenance of structure and flexibility can be appreciated if we remember that almost any simple motion—such as raising the arm out to the side—changes either the length or the tension values in most of the body’s muscle cells. If one is to avoid tipping towards the extended arm, then the feet, the legs, the hips, the back, the neck, and the opposite arm all must participate in a new distribution of balance created by the “isolated” movement of raising the arm. The difficulties experienced by every child learning to sit, to stand erect, and to walk with an even gait attest to the complexity of the demands which these shifts in balance and tone make upon us. The entire musculature must learn to participate in the motion of any of its parts. And to do this, the entire musculature must feel its own activity, fully and in rich detail. Competent posture and movement are among the chief points of sensory self-awareness. The purpose of bodywork is to heighten and focus this awareness. It is the child’s task during this early motor training to experiment by trial and error, and to set the precise lengths and tensions—and changes in length and tension—in all his muscle fibers for these basic skills of standing and walking. This is the education of the basal ganglia and the gamma motor system, as learned reflex responses are added to our inherited ones. The lengths and rates of change of the spindle fibers are set at values which experience has confirmed to be appropriate for the movement desired, and then the sensorimotor reflex arcs of the spindles and the Golgis command the alpha motor nerves, and hence the skeletal muscles, to respond exactly to those specifications that have been established in the gamma system by previous trial and error. And this chain of events holds true not only for the actual limb being moved, but for all other parts of the musculature that must brace, or shift, or compensate in any way. In this complicated process, the child is guided primarily by sensory cues which become more consistent and more predictable with every repetition of his efforts.

The predicted results of scientific enquiry and the actual results of scientific enquiry are diametrically opposed here, and no one seems to pay too much attention to the fact. The purpose of scientific method is to select a single truth from among many hypothetical truths. That, more than anything else, is what science is all about. But historically science has done exactly the opposite. Through multiplication upon multiplication of facts, information, theories and hypotheses, it is science itself that is leading mankind from single absolute truths to multiple, indeterminate, relative ones.
