Introduction.—The Circular Pendulum.—Law connecting the Time of Vibration with the Length.—The Force of Gravity determined by the Pendulum.—The Cycloid. INTRODUCTION. 589. If a weight be attached to a piece of string, the other end of which hangs from a fixed point, we have what is called a simple pendulum. The pendulum is of the utmost importance in science, as well as for its practical applications as a time-keeper. In this lecture and the next we shall treat of its general properties; and the last will be devoted to the practical applications. We shall commence with the simple pendulum, as already defined, and prove, by experiment, the remarkable property which was discovered by Galileo. The simple pendulum is often called the circular pendulum. THE CIRCULAR PENDULUM. Fig. 82. 590. We first experiment with a pendulum on a large scale. Our lecture theatre is 32 feet high, and there is a wire suspended from the ceiling 27' long; to the end of this a ball of cast iron weighing 25 lbs. is attached. This wire when at rest hangs vertically in the direction o c ( ). Fig. 82 I draw the ball from its position of rest to a; when released, it slowly returns to c, its original position; it then moves on the other side to b, and back again to my hand at a. The ball—or to speak more precisely, the centre of the ball—moves in a circle, the centre being the point o in the ceiling from which the wire is suspended. 591. What causes the motion of the pendulum when the weight is released? It is the force of gravity; for by moving the ball to a I raise it a little, and therefore, when I release it gravity compels it to return to c it being the only manner in which the mode of suspension will allow it to fall. But when it has reached its original position at c, why does it continue its motion?—for gravity must be acting against the ball during the journey from c to b. The first law of motion explains this. ( ). In travelling from a to c the ball has acquired a certain velocity, hence it has a tendency to go on, and only by the time it has arrived at b will gravity have arrested the velocity, and begin to make it descend. Art. 485 592. You see, the ball continues moving to and fro—oscillating, as it is called—for a long time. The fact is that it would oscillate for ever, were it not for the resistance of the air, and for some loss of energy at the point of suspension. [Pg 286] 593. By the time of an oscillation is meant the time of going from a to b, but not back again. The time of our long pendulum is nearly three seconds. 594. With reference to the time of oscillation Galileo made a great discovery. He found that whether the pendulum were swinging through the arc a b, or whether it had been brought to the point a´, and was thus describing the arc a´ b´, the time of oscillation remained nearly the same. The arc through which the pendulum oscillates is called its amplitude, so that we may enunciate this truth by saying that the time of oscillation is nearly independent of the amplitude. The means by which Galileo proved this would hardly be adopted in modern days. He allowed a pendulum to perform a certain number of vibrations, say 100, through the arc a b, and he counted his pulse during the time; he then counted the number of pulsations while the pendulum vibrated 100 times in the arc a´ b´, and he found the number of pulsations in the two cases to be equal. Assuming, what is probably true, that Galileo’s pulse remained uniform throughout the experiment, this result showed that the pendulum took the same time to perform 100 vibrations, whether it swung through the arc a b, or through the arc a´ b´. This discovery it was which first suggested the employment of the pendulum as a means of keeping time. 595. We shall adopt a different method to show that the time does not depend upon the amplitude. I have here an arrangement which is represented in . It consists of two pendulums a d and b c, each 12' long, and suspended from two points a b, about 1' apart, in the same horizontal line. Each of these pendulums carries a weight of the same size: they are in fact identical. Fig. 83 [Pg 287] Fig. 83. 596. I take one of the balls in each hand. If I withdraw each of them from its position of rest through equal distances and then release them, both balls return to my hands at the same instant. This might have been expected from the identity of the circumstances. [Pg 288] 597. I next withdraw the weight c in my right hand to a distance of 1', and the weight d in my left hand to a distance of 2', and release them simultaneously. What happens? I keep my hands steadily in the same position, and I find that the two weights return to them at the same instant. Hence, though one of the weights moved through an amplitude of 2' (c e) while the other moved through an amplitude of 4' (d f), the times occupied by each in making two oscillations are identical. If I draw the right-hand ball away 3', while I draw the left hand only 1' from their respective positions of rest, I still observe the same result. 598. In two oscillations we can see no effect on the time produced by the amplitude, and we are correct in saying that, when the amplitude is only a small fraction of the length of the pendulum, its effect is inappreciable. But if the amplitude of one pendulum were very large, we should find that its time of oscillation is slightly greater than that of the other, though to detect the difference would require a delicate test. One consequence of what is here remarked will be noticed at a later page. ( .) Art. 655 599. We next inquire whether the weight which is attached to the pendulum has any influence upon the time of vibration. Using the 12' pendulums of , I place a weight of 12 lbs. on one hook and one of 6 lbs. on the other. I withdraw one in each hand; I release them; they return to my hand at the same moment. Whether I withdraw the weights through long arcs or short arcs, equal or unequal, they invariably return together, and both therefore have the same time of vibration. With other iron weights the same law is confirmed, and hence we learn that, besides being independent of the amplitude, the time of vibration is also independent of the weight. Fig. 83 [Pg 289] 600. Finally, let us see if the material of the pendulum can influence its time of vibration. I place a ball of wood on one wire and a ball of iron on the other; I swing them as before: the vibrations are still performed in equal times. A ball of lead is found to swing in the same time as a ball of brass, and both in the same time as a ball of iron or of wood. 601. In this we may be reminded of the experiments on gravity ( ), where we showed that all bodies fall to the ground in equal times, whatever be their sizes or their materials. From both cases the inference is drawn that the force of gravity upon different bodies is proportional to their masses, though the bodies be made of various substances. It was indeed by means of experiments with the pendulum that Newton proved that gravity had this property, which is one of the most remarkable truths in nature. Art. 491 LAW CONNECTING THE TIME OF VIBRATION WITH THE LENGTH. 602. We have seen that the time of vibration of a pendulum depends neither upon its amplitude, material, nor weight; we have now to learn on what the time does depend. It depends upon the length of the pendulum. The shorter a pendulum the less is its time of vibration. We shall find by experiment the relation between the time and the length of the cord by which the weight is suspended. Fig. 84. 603. I have here ( ) two pendulums a d, b c, one of which is 12' long and the other 3'; they are mounted side by side, and the weights are at the same distance from the floor. I take one of the weights in each hand, and withdraw them to the same distance from the position of rest. I release the balls simultaneously; c moves off rapidly, arrives at the end c´ while d has only reached d´, and returns to my hand just as d has completed one oscillation. I do not seize c: it goes off again, only to return at the same moment when d reaches my hand. Thus c has performed four oscillations while d has made no more than two. This proves that when one of two pendulums is a quarter the length of the other, the time of vibration of the shorter one is half that of the other. Fig. 84 [Pg 291] 604. We shall repeat the experiment with another pendulum 27' long, suspended from the ceiling, and compare its vibrations with those of a pendulum 3' long. I draw the weights to one side and release them as before; and you see that the small pendulum returns twice to my hand while the long pendulum is still absent; but that, keeping my hands steadily in the same place throughout the experiment, the long pendulum at last returns simultaneously with the third arrival of the short one. Hence we learn that a pendulum 27' long takes three times as much time for a single vibration as a 3' pendulum. 605. The lengths of the three pendulums on which we have experimented (27', 12', 3'), are in the proportions of the numbers 9, 4, 1; and the times of the oscillations are proportional to 3, 2, 1: hence we learn that the period of oscillation of a pendulum is proportional to the square root of its length. 606. But the time of vibration must also depend upon gravity; for it is only owing to gravity that the pendulum vibrates at all. It is evident that, if gravity were increased, all bodies would fall to the earth more than 16' in the first second. The effect on the pendulum would be to draw the ball more quickly from d to d´ ( ), and thus the time of vibration would be diminished. Fig. 84 [Pg 292] It is found by calculation, and the result is confirmed by experiment, that the time of vibration is represented by the expression, 3·1416 √ ( Length / Force of gravity). 607. The accurate value of the force of gravity in London is 32·1908, so that the time of vibration of a pendulum there is 0·5537√ length: the length of the seconds pendulum is 3'·2616. THE FORCE OF GRAVITY DETERMINED BY THE PENDULUM. 608. The pendulum affords the proper means of measuring the force of gravity at any place on the earth. We have seen that the time of vibration can be expressed in terms of the length and the force of gravity; so conversely, when the length and the time of vibration are known, the force of gravity can be determined and the expression for it is— 609. It is impossible to observe the time of a single vibration with the necessary degree of accuracy; but supposing we consider a large number of vibrations, say 100, and find the time taken to perform them, we shall then learn the time of one oscillation by dividing the entire period by 100. The amplitudes of the oscillations may diminish, but they are still performed in the same time; and hence, if we are sure that we have not made a mistake of more than one second in the whole time, there cannot be an error of more than 0·01 second, in the time of one oscillation. By taking a still larger number the time may be determined with the utmost precision, so that this part of the inquiry presents little difficulty. [Pg 293] 610. But the length of the pendulum has also to be ascertained, and this is a rather baffling problem. The ideal pendulum whose length is required, is supposed to be composed of a very fine, perfectly flexible cord, at the end of which a particle without appreciable size is attached; but this is very different from the pendulum which we must employ. We are not sure of the exact position of the point of suspension, and, even if we had a perfect sphere for the weight, the distance between its centre and the point of suspension is not the same thing as the length of the simple pendulum that would vibrate in the same time. Owing to these circumstances, the measurement of the pendulum is embarrassed by considerable difficulties, which have however been overcome by ingenious contrivances to be described in the next chapter. 611. But we shall perform, in a very simple way, an experiment for determining the force of gravity. I have here a silken thread which is fastened by being clamped between two pieces of wood. A cast iron ball 2"·54 in diameter is suspended by this piece of silk. The distance from the point of suspension of the silk to the ball is 24"·07, as well as it can be measured. The length of the ideal pendulum which would vibrate isochronously with this pendulum is 25"·37, being about 0"·03 greater than the distance from the point of suspension to the centre of the sphere. 612. The length having been ascertained, the next element to be determined is the time of vibration. For this purpose I use a stop-watch, which can be started or stopped instantaneously by touching a little stud: this watch will indicate time accurately to one-fifth of a second. It is necessary that the pendulum should swing in a small arc, as otherwise the oscillations are not strictly isochronous. Quite sufficient amplitude is obtained by allowing the ball to rotate to and fro through a few tenths of an inch. [Pg 294] 613. In order to observe the movement easily, I have mounted a little telescope, through which I can view the top of the ball. In the eye-piece of the telescope a vertical wire is fastened, and I count each vibration just as the silken thread passes the vertical wire. Taking my seat with the stop-watch in my hand, I write down the position of the hands of the stop-watch, and then look through the telescope. I see the pendulum slowly moving to and fro, crossing the vertical wire at every vibration; on one occasion, just as it passes the wire, I touch the stud and start the watch. I allow the pendulum to make 300 vibrations, and as the silk arrives at the vertical wire for the 300th time, I promptly stop the watch; on reference I find that 241·6 seconds have elapsed since the time the watch was started. To avoid error, I repeat this experiment, with precisely the same result: 241·6 seconds are again required for the completion of 300 vibrations. 614. It is desirable to reckon the vibrations from the instant when the pendulum is at the middle of its stroke, rather than when it arrives at the end of the swing. In the former case the pendulum is moving with the greatest rapidity, and therefore the time of coincidence between the thread and the vertical wire can be observed with especial definiteness. 615. The time of a single vibration is found, by dividing 241·6 by 300, to be 0·805 second. This is certainly correct to within a thousandth part of a second. We conclude that a pendulum whose length is 25"·37 = 2·114, vibrates in 0·805 second; and from this we find that gravity at Dublin is 2'·114 × (3·1416 / 0.805)² = 32·196. This result agrees with one which has been determined by measurement made with every precaution. [Pg 295] Another method of measuring gravity by the pendulum will be described in the next lecture ( ). Art. 637 THE CYCLOID. 616. If the amplitude of the vibration of a circular pendulum bear a large proportion to the radius, the time of oscillation is slightly greater than if the amplitude be very small. The isochronism of the pendulum is only true for small arcs. 617. But there is a curve in which a weight may be made to move where the time of vibration is precisely the same, whatever be the amplitude. This curve is called a cycloid. It is the path described by a nail in the circumference of a wheel, as the wheel rolls along the ground. Thus, if a circle be rolled underneath the line a b ( ), a point on its circumference describes the cycloid a d c p b. The lower part of this curve does not differ very much from a circle whose centre is a certain point o above the curve. Fig. 85 618. Suppose we had a piece of wire carefully shaped to the cycloidal curve a d c p b, and that a ring could slide along it without friction, it would be found that, whether the ring be allowed to drop from c, p or b, it would fall to d precisely in the same time, and would then run up the wire to a distance from d on the other side equal to that from which it had originally started. In the oscillations on the cycloid, the amplitude is absolutely without effect upon the time. [Pg 296] 619. As a frictionless wire is impossible, we cannot adopt this method, but we can nevertheless construct a cycloidal pendulum in another way, by utilizing a property of the curve, o a ( ) as a half cycloid; in fact, o a is just the same curve as b d, but placed in a different position, so also is o b. If a string of length o d be suspended from the point o, and have a weight attached to it, the weight will describe the cycloid, provided that the string wrap itself along the arcs o a and o b; thus when the weight has moved from d to p, the string is wrapped along the curve through the space o t, the part t p only being free. This arrangement will always force the point p to move in the cycloidal arc. Fig. 85 Fig. 85. 620. We are now in a condition to ascertain experimentally, whether the time of oscillation in the cycloid is independent of the amplitude. We use for this purpose the apparatus shown in . d c e is the arc of the cycloid; two strings are attached at o, and equal weights a, b are suspended from them; c is the lowest point of the curve. The time a will take to fall through the arc a c is of course half the time of its oscillation. If, therefore, I can show that a and b both take the same time to fall down to c, I shall have proved that the vibrations are isochronous. Fig. 86 [Pg 297] Fig. 86. 621. Holding, as shown in the figure, a in one hand and b in the other, I release them simultaneously, and you see the result,—they both meet at c: even if I bring a up to e, and bring b down close to c, the result is the same. The motion of a is so rapid that it arrives at c just at the same instant as b. When I bring the two balls on the same side of c, and release them simultaneously, a overtakes b just at the moment when it is passing c. Hence, under all circumstances, the times of descent are equal. [Pg 298] 622. It will be noticed that the string attached to the ball b, in the position shown in the figure, is almost as free as if it were merely suspended from o, for it is only when the ball is some distance from the lowest point that the side arcs produce any appreciable effect in curving the string. The ball swings from b to c nearly in a circle of which the centre is at o. Hence, in the circular pendulum, the vibrations when small are isochronous, for in that case the cycloid and the circle become indistinguishable.

THE SIMPLE PENDULUM

Surviving Crypto Winter — Part Two: Blockstack and the Great Pendulum of History

I believe that the adoption of new technologies follows a particular pattern. However, I’m not talking about the familiar “Hype Cycle”. While this perspective can be helpful, it is also somewhat misleading: Gartner Hype Cycle The graph shows a simple peak and trough, but the reality is more like an ongoing tug backwards and forwards, between and . I’m calling this the “Hype Pendulum”: hype backlash Let me explain with a couple of examples from the world of web development. HTML5 and PWAs The iPhone App Store opened in 2008, 18 months after the launch of the phone. The web was suddenly left behind in terms of features; native was the cool kid. A couple of years later, Wired famously proclaimed the Web was “dead”. The Web standards community were busy working on HTML5 though. It reached the mainstream consciousness in 2010 when Steve Jobs posted his “Thoughts on Flash”. By 2011, with the HTML5 spec reaching “Last Call”, we we were experiencing something of a hype spike: “The hype created by the promise of HTML5 has almost reached fever pitch”- Mobile Foresight, 2011 Yet just a year later, Facebook famously “ditched” HTML5 in its native app. Once again, the web was written off. This moment probably marked the “trough of disillusionment” nadir. “When the pendulum swung away from HTML5 in 2012, it swung pretty far and scared away many potential innovators.”- ReadWriteWeb, 2013 But over the next few years, interest in web app technologies began to quietly rise up again. In 2015, a new term “Progressive Web Apps” was coined, to describe a bunch of approaches and capabilities that were all now possible. Now we’re in 2016 and we may be starting to see a hype spike once again: “By now, you’ve probably heard that Progressive Web Apps are the future of all mankind. They’ll bring world peace, end hunger, save the rainbows and unicorns, bring balance to the force, and a whole lot more.”- Ionic, 2016 I do truly believe PWAs have a future though. Perhaps there will be further swings of the pendulum before we’re fully settled in web apps’ — but I’m sure we’re getting there! big Plateau of Productivity Responsive Design People had been making responsive sites earlier, but the concept took off when Ethan Marcotte famously coined the term in his A List Apart article in May 2010. It received a tonne of attention, but it wasn’t long before dissenters pushed back, chiefly citing mobile performance versus separate mobile sites, an attachment to the “pixel perfect” designs of print media, or simply the perceived effort involved: “Responsive Web Design is NOT right for your website”- Blogger, 2013 “Responsive Design Is a Waste Of Time”- Blogger, 2013 “Responsive design really sucks”- Blogger, 2014 It took time for the Hype Pendulum to settle and for Responsive Design to be generally accepted as the default way to design web pages. I’d say it got there by around 2015, helped by Google’s SEO policies giving a boost to responsive sites. Hype Pendulums everywhere Does every new web undergo a Hype Pendulum? It seems so to me. For example, think of the reaction to any popular framework. technology JavaScript The example that actually inspired this post — thank you to ’ talk — is NPM. As the repository of code modules, NPM became a symbol of modular code design. NPM — and in turn, modular code — was the subject of a backlash in 2016 due to the left-pad controversy, which according to media outlets, ! Ashley Williams FFConf world’s largest “broke the internet” Node.js is another example. Originally written by Ryan Dahl in 2009, I remember first trying it out myself in 2010, the year that Express and Socket.io were born. It wasn’t long before the hype was in full swing: “Why nodeJS is awesome and why you shouldn’t even think about using it”- Blogger, 2013 The inevitable backlash included the infamous post. “Node.js is cancer” Why does this happen? The Hype Pendulum is partly a by-product of how our human attention works. Balanced, nuanced arguments don’t make such good headlines - rants get more clicks. Binary arguments and zero-sum games appeal due to their reassuring simplicity. Backlashes are also symptomatic of our impatience in a fast-moving world; when we hear about the shiny new technology or approach, we want to use it right away. It’s useful to remember that the extremes of hype and backlash are temporary fluctuations along a timeline of innovation that usually stretches out longer than we would like. Sometimes an early form of technology fails to fully take off, until it returns in a new form that’s more ready for prime time. Performance is a common theme of backlashes; thankfully the performance limitations tend to diminish over time with hardware advances and software optimisations. Sometimes our developer tooling and understanding take a while to catch up. It takes time for innovations to settle, as the shows: Long Nose of Innovation Long Nose of Innovation by Bill Buxton — image by sketchplanations.com It’s also a factor of our motivations. As web evangelists, it’s our role (and passion) to promote the latest technologies and best practices. As web developers, it’s our role to push back if we find real-world issues that need to be addressed. How to deal with it It can be tempting to immediately lurch towards the latest fad, or immediately rail against it. The safer bet is to leave the Hype Pendulum to swing, while we absorb information from both sides, try things out for ourselves and come to informed decisions. With the constant flurry of new libraries and frameworks, much has been said recently about the ‘fatigue’ this can lead to. As , . Ada Rose Edwards says “Knowing HTML, CSS and Vanilla JS through and through will have more long term merit than any flash in pan library or tool kit” As a developer advocate, please do call me out if I ever appear to be overly hyping up a new technique or approach, without due consideration to potential downsides. I have a tendency to say things are awesome ;-) The Lego Movie Although sometimes overly hasty and extreme, backlashes can be important. They can help to ensure that we don’t rush into releasing technology so quickly that we miss potential security or privacy issues. We don’t want to be Chad and Brad from Maciej Ceglowski’s — . “Who Will Command the Robot Armies?” “developers who are just trying to crush out some code out on deadline, and don’t think about the wider consequences of their actions” Although sometimes the Hype Pendulum may be tiresome, it’s generally productive. As Barack Obama , the path of progress . The hype around the latest web technologies may swing backwards and forwards, but this is the case for all innovations. As long as we keep progressing overall, we’ll leave the web in good shape: a better, stronger platform for everybody. And that really be awesome_!_ recently said “has never been a straight line. We zig and zag…” will Note: this article was written outside of my role as a Developer Advocate, but I work at Samsung Internet , Samsung’s mobile web browser.

The “Hype Pendulum” of Web Development

The morning began as it always did. Blanket aside, sleepy gait, morning ritual, and the usual way to work. Even if the place of work is the desk in the next room. Every successful coach screams about fighting this system. But in fact, you don't need to fight it. It's enough to understand how it works and use it to your benefit. That's what neurohacking is all about. Dopamine mining in the 21st century: inflation Huxley's Brave New World is a super-concentrated utopia in which sources of quick gratification have possessed people. A button come off? Buy a new piece. Food, sex, entertainment - everything is calibrated and available. Even social elevators are predetermined from birth and literally written into your genocode. But let's move away from fiction and look at reality. In it, cyberpsychology and society are closely intertwined into a single structure that generates myths, supports them, and brings them to life. Dopamine swing The whole marketing industry is swinging a huge pendulum of neurohormones. At its highest point is dopamine. And at its lowest point, corticoliberin. It is the fear hormone, and slogans press it: "offer is limited", "the goods are running out", "discount for the first 10 buyers": The fear of being inferior to others hits our nerves because the loss of social status is comparable to death. If a major official/banker/top manager loses his position, the probability of his suicide increases many times over. It seems to us that work remains the only lifeline, without which we will be doomed to die in misery. Technological advances have spawned a synthesis of psychological mechanisms with advances in cybernetics. Today, cyberpsychology understands how to engage a person in absorbing material. How to create an interest that spurs one to watch a new series, go through another rink, or spend hours watching ten-second videos of cats and songs. Millions of years of starvation still outweigh 200 years of conventional satiety. Calories have become more dangerous than lead bullets. We're like primitive humans opening fire. Only we're not just warming ourselves by the fire. The problem is that the fire has become too much, and we are literally burning alive. Even though modern life is safe enough, the body refuses to accept it. Any lunge towards our safety or any threat to our social status is met with hostility. And the brain starts looking for solutions. Marketers present them on a silver platter. Speed is the main adversary We want to solve problems quickly. We also want achievements to stay with us for a long time. But what exactly they should look like, we have no idea. To be more precise, we stopped having about since childhood. Back then, we knew exactly the charm of the very stick, an unusual stone, or could wander for hours among a few trees while our brains drew incredible pictures of grandeur and adventure. But now we look up to seeming authorities who are slightly different from us. Authoritarians who broadcast the same things from every screen: Only true professionals use this smartphone. The super camera, the incredible processor, the screen with the number of colors your eye can't distinguish anyway. But this device becomes obsolete after a year, and you must make your next purchase to get back on track. Want to be fashionable? Here are the expensive brands. Here are ready-to-wear collections. Here are the dressed mannequins. Just take the same and enjoy! You don't need to tell everyone you are rich and fashion-savvy. Just wear the things we've already prepared for you. Have you heard of such a thing as constant self-development? We already spend a third of our lives sleeping! Don't waste time being bored. Boredom and procrastination are a virus worse than COVID-19. Here's a new series, a new movie, a new game. Give your brain a chance to solve interesting puzzles and sit down to work afterward. Develop your cultural experience. Play games, pumping up your game character. Just for your own sake, don't fall into laziness. Otherwise, unnecessary thoughts will start popping up in your head. Add to this shopping on the Internet, delivery services, social networking sites, and a man charged with caffeine who rushes through a maze of entertainment devices in pursuit of the horizon line that looms on every screen. And there is no way to get to it. Neurohacking of dopamine sources So, so far, the situation looks extremely unpleasant. There is a huge target on everyone's forehead, into which a beam of information stimuli is relentlessly beating. It is almost impossible to escape, but there is a way out. Neurohacking is not about taking grandmother's drugs to enhance brain activity. It is a way of life formed from understanding cognitive-behavioral principles and working not with the form of stimuli but with their essence. Power of habits "Step on the system". It applies to people with any type of addiction. Alcohol, drugs, and gambling become a natural ritual, like brushing your teeth or the route to work. To beat the system in the literal sense of the word is impossible. After all, fighting it will already be a reminder of its existence. Therefore, use switching: A notepad or text file in which you write down 3-5 events every day that brought you a moment of happiness. A beautiful sunset, a walk after the office, a dog you petted, a delicious lunch you made yourself. Allowing boredom. Boredom and procrastination are the same as a fever during a cold. It's only worth bringing it down when it's critical. Boredom indicates that you are doing something meaningless. And, quite possibly, there are more productive areas that need your attention. So it's worth giving them a little more attention. Cleansing. I think you know the feeling of not wanting to go to the shower. And then you don't want to get out of it. Same thing with dopamine. Walking on the landing with your smartphone turned off and not even music in your headphones... It seems like torture, but it will be extremely difficult to complete once you start the walk. For starters, you don't have to take it seriously. You're not struggling. You're not giving up habits. You are trying a new way of life. Everything is available to you, and nothing is beyond your control. This is the basis for the principles of Stoicism, which serves as a great balancing act when categorizing personal values. Shifting focus: what is stigmatized by marketers What's written above is a child's warm-up. You know, like morning exercise compared to professional sports. Only your main competition is all the mass marketing. Because to find happiness, you don't need marketing attributes. Comparing yourself with images on advertising posters is similar to biting your nails or lips. It is a kind of 21st-century self-harm. Cyberpsychology studies the tools used in the media by people and companies. These tools dictate the precepts of a successful, productive world. But their status quo can be disrupted by an alternate view conjured up in the mind: You don't need a new keyboard, a smartphone, or a branded notepad to be successful. You can afford all of those things. But it has no power over you. Buy things to get a dopamine boost. But remember that they are only things, and you can easily gift them to loved ones. Or part with them with no regrets. Happiness, like success, cannot be an attainable goal. Like, for example, a profession. It seems that here I will become a freelancer and will type on a chaise lounge on the island. But the screen glares, the charge is not enough, typing is uncomfortable, and it is generally hot. Happiness, success, and freelancing are states, but not an end in themselves. And it is almost impossible to acquire them. Your lifestyle will always seem miserable to some people. And someone will be shocked by its luxury. As Peter H. Diamandis wrote, there are 2 kinds of poverty. Absolute, when you have nothing to eat, and relative, when everyone else has the 12th iPhone, and you have only the 11th. You already have everything you need to experience pleasure and happiness. But it's like comparing a home chandelier to the 3D hologram from the Blade Runner remake... Advertising will always be brighter and more attractive. We will never own the products of the marketing world but only rent them, committing to changing sets of clothes, appliances, and even our personal data. They are left on a hundred websites and no longer belong to us but to supposedly secure databases. Is dopamine gluttony so bad? It may seem like a fierce criticism of modern society and consumer culture. But I'm not. It's more of an illumination of the situation as a whole. Marketing does put pressure on the mind, but companies can't do otherwise. But we can. There is already a culture of alcohol consumption in society. So why stop at just that? A culture of consuming gaming content, media content, marketing content... The excess of stimuli pushing on the dopamine receptors can really be bypassed. It's enough to choose your own goals, instead of being guided by marketing tricks. And yes, you just took a ride on the dopamine-corticoliberine swing.
