I have learnt through bitter experience the one supreme lesson to conserve my anger, and as heat conserved is transmuted into energy, even so our anger controlled can be transmuted into a power which can move the world.
Mahatma Gandhi
Be master of your petty annoyances and conserve your energies for the big, worthwhile things. It isn't the mountain ahead that wears you out - it's the grain of sand in your shoe.
Robert W. Service
Mr Churchill, to what do you attribute your success in life? Conservation of energy. Never stand up when you can sit down. And never sit down when you can lie down.
Winston S. Churchill
Just as there are laws of Conservation of Matter and Energy, so there are in fact Laws of Conservation of Pain and Joy. Neither can ever be created or destroyed. But one can be converted into the other.
Spider Robinson (Callahan's Crosstime Saloon (Callahan's, #1))
But, if we consider, as physicists now claim, that everything is energy—everything we see, everything we think, everything we do—then it is just possible that this same law of conservation of energy applies to questions of morality. A conservation of moral energy, a maintenance of equilibrium… a balance exists and must be preserved. If an action is taken that disrupts that balance, then an action similar in kind and degree is required to restore equilibrium.
J.K. Franko (Eye for Eye (Talion #1))
Nature may reach the same result in many ways. Like a wave in the physical world, in the infinite ocean of the medium which pervades all, so in the world of organisms, in life, an impulse started proceeds onward, at times, may be, with the speed of light, at times, again, so slowly that for ages and ages it seems to stay, passing through processes of a complexity inconceivable to men, but in all its forms, in all its stages, its energy ever and ever integrally present. A single ray of light from a distant star falling upon the eye of a tyrant in bygone times may have altered the course of his life, may have changed the destiny of nations, may have transformed the surface of the globe, so intricate, so inconceivably complex are the processes in Nature. In no way can we get such an overwhelming idea of the grandeur of Nature than when we consider, that in accordance with the law of the conservation of energy, throughout the Infinite, the forces are in a perfect balance, and hence the energy of a single thought may determine the motion of a universe.
Nikola Tesla
Coal, oil and gas are called fossil fuels, because they are mostly made of the fossil remains of beings from long ago. The chemical energy within them is a kind of stored sunlight originally accumulated by ancient plants. Our civilization runs by burning the remains of humble creatures who inhabited the Earth hundreds of millions of years before the first humans came on the scene. Like some ghastly cannibal cult, we subsist on the dead bodies of our ancestors and distant relatives.
Carl Sagan (Billions & Billions: Thoughts on Life and Death at the Brink of the Millennium)
He comes into my city, he throws away my people, he orders me around like I'm his servant and now this? How dare he!" I sighed. "How dare he!" came out. Could "Does he know who I am?" be far behind? "I'm not some illiterate he can push around. I won't be treated this way. I worked too damn hard, for years. Years! Years of study and that fucking Neanderthal comes in and waves his arms." Ghastek skewed his face into a grimace. He was probably aiming to impersonate Hugh, but he mostly succeeded in looking extremely constipated. "Ooo, I'm Hugh d'Ambray, I'm starting a war!" Laughing right now was a really bad idea. I had to conserve the energy. "A war I've been trying years to avoid. Years!" He kept saying that. "Does he think it's easy to negotiate with violent lunatics, who can't understand elementary concepts?" Good to know where we stood with him.
Ilona Andrews (Magic Breaks (Kate Daniels, #7))
Our brain actually prefers to spend most of its time coasting on autopilot—it is best able to conserve its energy by knowing what to expect. This is why our habits and routines feel so comforting
Nicole LePera (How to Do the Work: Recognize Your Patterns, Heal from Your Past, and Create Your Self)
Fear sits and smiles and is predatory, immobile and silent and serene; an observer who conserves his energy and is content to wait.
John Scalzi (The Sagan Diary (Old Man's War, #2.5))
You lose track of time when you're deep in conservation with an otherworldly being made of pure Loric energy.
Pittacus Lore (The Fate of Ten (Lorien Legacies, #6))
Strangely enough, doctors and nurses noted that activity actually prolonged life, when it should have shortened it. Those who lay down and tried to conserve energy often were the ones who trailed off and died first.
M.T. Anderson (Symphony for the City of the Dead: Dmitri Shostakovich and the Siege of Leningrad)
Thought isn't a form of energy. So how on Earth can it change material processes? That question has still not been answered.
Vladimir I. Vernadsky
There's a grosser irony about Politically Correct English. This is that PCE purports to be the dialect of progressive reform but is in fact--in its Orwellian substitution of the euphemisms of social equality for social equality itself--of vastly more help to conservatives and the US status quo than traditional SNOOT prescriptions ever were. Were I, for instance, a political conservative who opposed using taxation as a means of redistributing national wealth, I would be delighted to watch PC progressives spend their time and energy arguing over whether a poor person should be described as "low-income" or "economically disadvantaged" or "pre-prosperous" rather than constructing effective public arguments for redistributive legislation or higher marginal tax rates. [...] In other words, PCE acts as a form of censorship, and censorship always serves the status quo.
David Foster Wallace (Consider the Lobster and Other Essays)
Throughout my life, I have never stopped to strategize about my next steps. I often just keep walking along, through whichever door opens. I have been on a journey and this journey has never stopped. When the journey is acknowledged and sustained by those I work with, they are a source of inspiration, energy and encouragement. They are the reasons I kept walking, and will keep walking, as long as my knees hold out.
Wangari Maathai
But the fatigue of physical dysfunction, I came to recognize, is as different from normal sleep deprivation as COVID-19 is from the common cold. It was not caused by needing sleep, I thought, but by my body’s cellular conviction that it needed to conserve energy in order to fix whatever was wrong. The feeling erased my will, the sense of identity that drives most of us. The worst part of my fatigue was the loss of an intact sense of self.
Meghan O'Rourke (The Invisible Kingdom: Reimagining Chronic Illness)
I believe that just as everyone inherits a particular form so does he inherit the particular characteristics and qualities of his progenitors, and to make this admission is to conserve one's energy.
Mahatma Gandhi
He's treating her like she's fourteen and he's a normal adult, acting like he's taken her under his wing. Like he needs her detecting skills, same as Barrons did to Mac, and she's falling for it, same as Mac. He's lining up his dominoes, so they fall more easily when he feels like pushing them over, conserving energy so he doesn't have to hunt her when he's ready to kill her.
Karen Marie Moning (Iced (Fever, #6))
Life should be built on the conservation of energy.
Herbert M. Shelton
To us investigators, the concept 'soul' is irrelevant and a matter for laughter.
Ernst Mach (History and Root of the Principle of the Conservation of Energy)
Nations are like people. When they grow old and rich and fat they get conservative. They exhaust their energy trying to keep things the way they are—and that’s against nature. Oh,
Pat Frank (Alas, Babylon)
The startling truth is that our best efforts for civil rights, international peace, population control, conservation of natural resources, and assistance to the starving of the earth—urgent as they are—will destroy rather than help if made in the present spirit. For, as things stand, we have nothing to give. If our own riches and our own way of life are not enjoyed here, they will not be enjoyed anywhere else. Certainly they will supply the immediate jolt of energy and hope that methedrine, and similar drugs, give in extreme fatigue. But peace can be made only by those who are peaceful, and love can be shown only by those who love. No work of love will flourish out of guilt, fear, or hollowness of heart, just as no valid plans for the future can be made by those who have no capacity for living now.
Alan W. Watts (The Book: On the Taboo Against Knowing Who You Are)
I baptize you in the name of the conservation of energy. What comes around goes around.
Maile Meloy
I knew he was unreliable, but he was fun to be with. He was a child’s ideal companion, full of surprises and happy animal energy. He enjoyed food and drink. He liked to try new things. He brought home coconuts, papayas, mangoes, and urged them on our reluctant conservative selves. On Sundays he liked to discover new places, take us on endless bus or trolley rides to some new park or beach he knew about. He always counseled daring, in whatever situation, the courage to test the unknown, an instruction that was thematically in opposition to my mother’s.
E.L. Doctorow (World's Fair)
Speaking biologically, fruit in a slightly shriveled state is holding its respiration and energy consumption down to the lowest possible level. It is like a person in meditation: his metabolism, respiration, and calorie consumption reach an extremely low level. Even if he fasts, the energy within the body will be conserved. In the same way, when mandarin oranges grow wrinkled, when fruit shrivels, when vegetables wilt, they are in the state that will preserve their food value for the longest possible time.
Masanobu Fukuoka (The One-Straw Revolution)
Axiom: the best place to conserve your water is in your body. It keeps your energy up. You’re stronger. Trust your stillsuit.” She
Frank Herbert (Dune (Dune, #1))
I just want to know what I’m going to be freaking out about before I waste energy freaking out about the wrong things. Conservation of panic is important.
Mira Grant (Parasite (Parasitology, #1))
Mom always says I need to spend less time on the couch and more time being active. But the way I see it. I'm just conserving my energy for later on. When all my friends are in their eighties and their bodies are broken down, I'll just be getting started.
Jeff Kinney (Cabin Fever (Diary of a Wimpy Kid, #6))
The abjectly poor, and all those persons whose energies are entirely absorbed by the struggle for daily sustenance, are conservative because they cannot afford the effort of taking thought for the day after tomorrow; just as the highly prosperous are conservative because they have small occasion to be discontented with the situation as it stands today.
Thorstein Veblen (The Theory of the Leisure Class)
With the energy he had conserved yesterday letting her dress him, he had written a note and pinned it in his pocket. IF FOUND DEAD SHIP EXPRESS COLLECT TO COLEMAN PARRUM, CORINTH, GEORGIA. Under this he had continued: COLEMAN SELL MY BELONGINGS AND PAY THE FREIGHT ON ME & THE UNDERTAKER. ANYTHING LEFT OVER YOU CAN KEEP. YOURS TRULY T. C. TANNER. P.S. STAY WHERE YOU ARE. DON’T LET THEM TALK YOU INTO COMING UP HERE. ITS NO KIND OF PLACE.
Flannery O'Connor (The Complete Stories)
Ironically, the serious study of the impossible has frequently opened up rich and entirely unexpected domains of science. For example, over the centuries the frustrating and futile search for a “perpetual motion machine” led physicists to conclude that such a machine was impossible, forcing them to postulate the conservation of energy and the three laws of thermodynamics. Thus the futile search to build perpetual motion machines helped to open up the entirely new field of thermodynamics, which in part laid the foundation of the steam engine, the machine age, and modern industrial society.
Michio Kaku (Physics of the Impossible: A Scientific Exploration of the World of Phasers, Force Fields, Teleportation and Time Travel)
There are thousands of agreements you have made with yourself, with other people, with your dream of life, with God, with society, with your parents, with your spouse, with your children. But the most important agreements are the ones you made with yourself. In these agreements you tell yourself who you are, what you feel, what you believe, and how to behave. The result is what you call your personality. In these agreements you say, “This is what i am; this is what I believe. I can do certain things, and some things I cannot do. This is reality; that is fantasy. This is possible; that is impossible.” One single agreement is not such a problem. But we have many agreements that make us suffer, that make us fail in life. If you want to live a life of joy and fulfillment, you have to find the courage to break those agreements that are fear-based and claim your personal power. The agreements that come from fear require us to expend a lot of energy, but the agreements that come from love help us to conserve energy and even gain extra energy.
Miguel Ruiz
You turned into a cat! A SMALL cat! You violated Conservation of Energy! That's not just an arbitrary rule, it's implied by the form of the quantum Hamiltonian! Rejecting it destroys unitarity and then you get FTL signalling! And cats are COMPLICATED! A human mind can't just visualise a whole cat's anatomy and, and all the cat biochemistry, and what about the neurology? How can you go on thinking using a cat-sized brain?
Eliezer Yudkowsky (Harry Potter and the Methods of Rationality)
Even viewed conservatively, trees are worth far more than they cost to plant and maintain. The U.S. Forest Service's Center for Urban Forest Research found a ten-degree difference between the cool of a shaded park in Tucson and the open Sonoran desert. A tree planted in the right place, the center estimates, reduces the demand for air conditioning and can save 100 kilowatt hours in annual electrical use, about 2 to 8 percent of total use. Strategically planted trees can also shelter homes from wind, and in cold weather they can reduce heating fuel costs by 10 to 12 percent. A million strategically planted trees, the center figures, can save $10 million in energy costs. And trees increase property values, as much as 1 percent for each mature tree. These savings are offset somewhat by the cost of planting and maintaining trees, but on balance, if we had to pay for the services that trees provide, we couldn't afford them. Because trees offer their services in silence, and for free, we take them for granted.
Jim Robbins (The Man Who Planted Trees: Lost Groves, Champion Trees, and an Urgent Plan to Save the Planet)
Unlike music, excessive reading has been shown to be dangerous for the female mind. It was taught in our earliest lectures: the male cells are essentially katabolic: active energetic; and female cells are anabolic: there to conserve energy and support life. While a little light reading is fine, breakdown follows when woman goes against her nature.
Anna Hope (The Ballroom)
How about you get on my back? So in a way you’re not being carried – you’re riding me.” I paused and then winked. Kat stared. “What?” I laughed, and her eyes immediately narrowed. “You should see yourself right now. Like a kitten – that’s what I keep telling you. Your hackles are raised.” Her eyes rolled as she shuffled behind me. “You should conserve your energy and stop talking.” “Ouch.” “You’ll get over it.” She placed her hands on my shoulders. “Besides, you could be knocked down a peg or two.” ... “Baby, I’m so far up the ladder there aren’t any pegs under me to be knocked down.” “Wow”, she said. “That’s a new one.” “You loved it.” .. “Hold on, Kitten. I’m going to start to glow just a little, and we’re going to go fast.” “I like when you glow. It’s like having my own personal flashlight.” I grinned. “Glad I can be of assistance.” She patted my chest. “Giddy up.
Jennifer L. Armentrout (Origin (Lux, #4))
This simple fact explains an awful lot about the biology and conservation of bumblebees. They have to eat almost continually to keep warm; a bumblebee with a full stomach is only ever about forty minutes from starvation. If a bumblebee runs out of energy, she cannot fly, and if she cannot fly, she cannot get to flowers to get more food, so she is doomed
Dave Goulson (A Sting in the Tale: My Adventures with Bumblebees)
However, in order to make progress in anything, we must make the first move - from then on, our personal rhythm and intuition will show us how to conserve his energy.
Paulo Coelho (Warrior of the Light)
Learn to twinkle your shine; because, it's beautiful!
Twinkle Sharma
Of all the conservation laws, that dealing with energy is the most difficult and abstract, and yet the most useful. It
Richard P. Feynman (The Character of Physical Law (Penguin Press Science))
complacent.26 When it comes to hiring, raising money, or even conserving energy, people aren’t rational robots. Where they stand in relation to others affects motivation.
Jonah Berger (Invisible Influence: The Hidden Forces that Shape Behavior)
I am out of ideas and need to conserve my energy so I can freak out more efficiently.
Maureen Johnson (The Hand on the Wall (Truly Devious, #3))
There was an interesting early relationship between physics and biology in which biology helped physics in the discovery of the conservation of energy, which was first demonstrated by Mayer in connection with the amount of heat taken in and given out by a living creature.
Richard P. Feynman (The Feynman Lectures on Physics Vol 1)
I do have hope. Nature is enormously resilient, humans are vastly intelligent, the energy and enthusiasm that can be kindled among young people seems without limit, and he human spirit is indomitable. But if we want life, we will have to stop depending on someone else to save the world. It is up to us-you and me, all of us. Myself, I have placed my faith in the children.
Jane Goodall
Conserve your energy. Focus on thoughts that matter. Use your time to advance, to progress, to grow, not to dwell on what someone thinks about your ability to advance, to progress, and grow.
Liz Faublas
Shared pain is lessened; shared joy, increased—thus do we refute entropy." Stated another way: "Just as there are Laws of Conservation of Matter and Energy, so there are in fact Laws of Conservation of Pain and Joy. Neither can ever be created or destroyed. But one can be converted into the other.
Spider Robinson
Yogis know that sex-energy may be conserved and used for the development of the body and mind of the individual, instead of being dissipated in unnatural excesses as is the wont of so many uninformed people.
William Walker Atkinson (The Science of Breathing)
There’s not one positive thing about being broke. The worst of it is the day-to-day grind of it all. You never know when that treadmill is finally going to buckle and hurl you into the wall. So you find yourself having to run faster and faster, just to keep from falling off. You can adjust to the hunger and the tiredness for the most part, having to choose between feeding yourself and feeding your electric meter; but one thing you can’t adjust to is the nagging anxiety. Whoever designed this loathsome system must think we’re all living these wonderful lives where money grows in the palms of our hands. There’s never any reassurance that everything is going to be okay; a promise that tomorrow will be slightly more bearable than today. Every minute of your life is consumed by a relentless feeling that time will only ever lead you to the worst possible outcome. And why—when you haven’t eaten a decent meal in two weeks and you’ve spent the last four days lying on a mattress just to conserve energy— should you believe any differently?
Rupert Dreyfus (B R O K E)
The thing that you must remember about energy is that it is conserved, which is to say that there is always the same amount of it. It may convert from one form or another but the total amount is always the same.
Robert Gilmore (Alice in Quantumland: An Allegory of Quantum Physics)
It is a sad state of affairs that I do not know of any astronomer who fully understands the energy in their own daily environment. Until that changes, Dark Energy will always be a mystery to the astronomical community.
Steven Magee
What is consciousness?” I asked. “I don’t know,” he replied, after a little hesitation. “Never mind,” I said. “Let’s think of something easier. What is energy?” “Well,” he said, “we can measure it and write down the equations governing its conservation.” “Yes, I know, but that was not my question. My question was: what is it?” “We don’t know,” he said with a grin, “and I think you were aware of that.” “Yes, like you I have read Feynman and he says that no one knows what energy is. That brings me to my main point. Would I be right in thinking that you were about to dismiss me (and my belief in God) if I failed to explain the divine and human nature of Christ?” He grinned again, and said nothing. I went on: “Well, by the same token, would you be happy if I now dismiss you and all your knowledge of physics because you cannot explain to me the nature of energy? After all, energy is surely by definition much less complex than the God who created it?” “Please don’t!” he said. “No, I am not going to do that, but I am going to put another question to you: why do you believe in the concepts of consciousness and energy, even though you do not understand them fully? Is it not because of the explanatory power of those concepts?” “I see what you are driving at,” he replied. “You believe that Jesus Christ is both God and man because that is the only explanation that has the power to make sense of what we know of him?” “Exactly.
John C. Lennox (Against the Flow: The inspiration of Daniel in an age of relativism)
First, when you try to restrict calories and exercise more, your body is hardwired to perceive a starvation situation. That makes you tired (so you move less and conserve energy) and hungry (so you eat more), and it slows down your metabolism (so you don’t die!). This “eat less, exercise more” formula is not too successful for most people. It can work for a short time, certainly, but less than 10 percent of people lose weight and keep it off for a year;4 you will almost always rebound and gain back the weight. Second, when you eat carbs and sugar, insulin spikes and your blood sugar drops. The insulin drives most of the available fuel in your bloodstream into fat cells, especially the fat cells around your middle, otherwise known as belly fat. So your body is starved of fuel, and this stimulates your brain5 to make you eat more.6 You could have a year’s worth of stored energy in your fat tissue and yet feel like you are starving. The only thing that can stop this vicious cycle is eating a lot of fat and cutting out the refined carbs and sugar. A high-fat, low-carb diet leads to a faster metabolism and sustained weight loss.
Mark Hyman (Eat Fat Get Thin: Why the Fat We Eat Is the Key to Sustained Weight Loss and Vibrant Health)
Knowing that life is a marathon and not a sprint is important. Conserve your energy. Understand that each battle is only one of many and that you can use it to make the next one easier. More important, you must keep them all in real perspective. Passing one obstacle simply says you’re worthy of more. The world seems to keep throwing them at you once it knows you can take it. Which is good, because we get better with every attempt. Never rattled. Never frantic. Always hustling and acting with creativity. Never anything but deliberate. Never attempting to do the impossible—but everything up to that line. Simply flipping the obstacles that life throws at you by improving in spite of them, because of them. And therefore no longer afraid. But excited, cheerful, and eagerly anticipating the next round.
Ryan Holiday (The Obstacle Is the Way: The Timeless Art of Turning Trials into Triumph)
the harm that Albertine had done me was a last bond between her and myself which outlived memory even, for with the conservation of energy which belongs to everything that is physical, suffering has no need of the lessons of memory.
Marcel Proust (In Search of Lost Time [volumes 1 to 7])
The link between willpower and decision making works both ways: Decision making depletes your willpower, and once your willpower is depleted, you’re less able to make decisions. If your work requires you to make hard decisions all day long, at some point you’re going to be depleted and start looking for ways to conserve energy. You’ll look for excuses to avoid or postpone decisions. You’ll look for the easiest and safest option, which often is to stick with the status quo: Leave the prisoner in prison.
Roy F. Baumeister (Willpower: Rediscovering the Greatest Human Strength)
So how can we improve the educational system? We should probably first rethink school curricula, and link them in more obvious ways to social goals (elimination of poverty and crime, elevation of human rights, etc.), technological goals (boosting energy conservation, space exploration, nanotechnology, etc.), and medical goals (cures for cancer, diabetes, obesity, etc.) that we care about as a society.
Dan Ariely (The Irrational Bundle: Predictably Irrational, The Upside of Irrationality, and The Honest Truth About Dishonesty)
A conservative is not merely an obstructionist who wishes to resist the introduction of novelties; nor is he, as was assumed by most 19th-century parliamentarians, a brake to frivolous experiment. He has positive work to do ... Civilization has no force of its own beyond what is given from within. It is under constant assault and it takes most of the energies of civilized man to keep going at all ... If [it] falls we shall see not merely the dissolution of a few joint-stock corporations, but of the spiritual and material achievements of our history.
Evelyn Waugh (Robbery Under Law)
This leads to a pattern in which the child cries out and either gets nothing or gets an insufficient or intermittent response. Then the child becomes exhausted and collapses, either from depleted energy or giving up to conserve a sliver of energy (Lowen, 1971). It is often at this point--collapse--that the caregiver eventually takes care of the child. This "teaches" the child that he or she has no effect on the world and that nurturance comes when they are collapsed.
Elliot Greene (The Psychology of the Body (Lww Massage Therapy & Bodywork Educational Series))
To Nature nothing can be added; from Nature nothing can be taken away; the sum of her energies is constant, and the utmost man can do in the pursuit of physical truth, or in the applications of physical knowledge, is to shift the constituents of the never-varying total. The law of conservation rigidly excludes both creation and annihilation. Waves may change to ripples, and ripples to waves; magnitude may be substituted for number, and number for magnitude; asteroids may aggregate to suns, suns may resolve themselves into florae and faunae, and floras and faunas melt in air: the flux of power is eternally the same. It rolls in music through the ages, and all terrestrial energy—the manifestations of life as well as the display of phenomena—are but the modulations of its rhythm.
John Tyndall
Many conscientious environmentalists are repelled by the word "abundance," automatically associating it with irresponsible consumerism and plundering of Earth's resources. In the context of grassroots frustration, insensitive enthusing about the potential for energy abundance usually elicits an annoyed retort. "We have to conserve." The authors believe the human family also has to _choose_. The people we speak with at the recycling depot or organic juice bar are for the most part not looking at the _difference_ between harmony-with-nature technologies and exploitative practices such as mountaintop coal mining. "Destructive" was yesterday's technology of choice. As a result, the words "science and technology" are repugnant to many of the people who passionately care about health, peace, justice and the biosphere. Usually these acquaintances haven't heard about the variety of constructive yet powerful clean energy technologies that have the potential to gradually replace oil and nuclear industries if allowed. Wastewater-into-energy technologies could clean up waterways and other variations solve the problem of polluting feedlots and landfills.
Jeane Manning (Breakthrough Power: How Quantum-Leap New Energy Inventions Can Transform Our World)

Nikola Tesla (Quotations by Nikola Tesla)
But we have reason to think that the annihilation of work is no less a physical impossibility than its creation, that is, than perpetual motion.
George Gabriel Stokes
We need to constantly absorb energy from the universe through food, exercise, and daily activities and need to conserve the use of energy for a vibrant, healthy, and long life.
Julia H. Sun
In fact, that there is no perpetual motion at all is a general statement of the law of conservation of energy.
Richard P. Feynman
The trees understand us; they are our friends. The trees transmit positive energy; they recharge us. Never stop loving the trees. They give life to earth.
Avijeet Das
Consider the boundaries you need to conserve your energy and operate at your best.
Miranda Hart (I Haven’t Been Entirely Honest with You)
This conservation law is very useful in many technical ways. I will give you some very simple examples to show how, knowing the law of conservation of energy and the formulae for calculating energy, we can understand other laws. In other words many other laws are not independent, but are simply secret ways of talking about the conservation of energy. The simplest is the law of the lever (fig. 16). Figure 16
Richard P. Feynman (The Character of Physical Law (Penguin Press Science))
Energy can neither be created nor destroyed, and so the total amount of energy which is present before and after any physical transaction will not be changed. This principle is called ‘the conservation of energy’.
J.E. Gordon (Structures: Or Why Things Don't Fall Down)
Diets don’t work because they require us to live in a constant state of war with our bodies. “Whenever you restrict food intake, you’re going to run up against your own biology,” explains Dr. Sharma. “It doesn’t matter what program you follow. As soon as your body senses that there are fewer calories going in than going out, it harnesses a whole array of defense mechanisms to fight that.” When we’re dieting, our bodies try to conserve energy, so our metabolism slows down, the result being that you have to eat even less to keep losing weight. That becomes an increasingly difficult project because our bodies also produce more of the hormones, such as ghrelin, that trigger hunger. There is even some evidence that the bacteria in our guts respond when we eat fewer calories, shifting their populations in ways that will send more hunger signals to our brains.
Virginia Sole-Smith (The Eating Instinct: Food Culture, Body Image, and Guilt in America)
The professional arms himself with patience, not only to give the stars time to align in his career, but to keep himself from flaming out in each individual work. He knows that any job, whether it’s a novel or a kitchen remodel, takes twice as long as he thinks and costs twice as much. He accepts that. He recognizes it as reality. The professional steels himself at the start of a project, reminding himself it is the Iditarod, not the sixty-yard dash. He conserves his energy. He prepares his mind for the long haul. He sustains himself with the knowledge that if he can just keep those huskies mushing, sooner or later the sled will pull in to Nome.
Steven Pressfield (The War of Art)
The law of conservation of energy, reborn as the law of conservation of mass/energy, has established itself as one of the few unshakable theoretical guideposts in the wilderness of the world of our sense experiences. In scope and generality it surpasses Newton's laws of motion, Maxwell's equations for electricity and magnetism, and even Einstein's potent little E=mc². It comes as close to an absolute truth as our uncertain age will permit.
Hans Christian Von Baeyer (Warmth Disperses and Time Passes: The History of Heat (Modern Library (Paperback)))
The physicist uses ordinary words in a peculiar manner. To him a conservation law means that there is a number which you can calculate at one moment, then as nature undergoes its multitude of changes, if you calculate this quantity again at a later time it will be the same as it was before, the number does not change. An example is the conservation of energy. There is a quantity that you can calculate according to a certain rule, and it comes out the same answer always, no matter what happens.
Richard P. Feynman (The Character of Physical Law (Penguin Press Science))
Atheism is the default position in any scientific inquiry, just as a-quarkism or a-neutrinoism was. That is, any entity has to earn its admission into a scientific account either via direct evidence for its existence or because it plays some fundamental explanatory role. Before the theoretical need for neutrinos was appreciated (to preserve the conservation of energy) and then later experimental detection was made, they were not part of the accepted physical account of the world. To say physicists in 1900 were 'agnostic' about neutrinos sounds wrong: they just did not believe there were such things. As yet, there is no direct experimental evidence of a deity, and in order for the postulation of a deity to play an explanatory role there would have to be a lot of detail about how it would act. If, as you have suggested, we are not “good judges of how the deity would behave,” then such an unknown and unpredictable deity cannot provide good explanatory grounds for any phenomenon. The problem with the 'minimal view' is that in trying to be as vague as possible about the nature and motivation of the deity, the hypothesis loses any explanatory force, and so cannot be admitted on scientific grounds. Of course, as the example of quarks and neutrinos shows, scientific accounts change in response to new data and new theory. The default position can be overcome.

How do fields express their principles? Physicists use terms like photons, electrons, quarks, quantum wave functions, relativity, and energy conservation. Astronomers use terms like planets, stars, galaxies, Hubble shift, and black holes. Thermodynamicists use terms like entropy, first law, second law, and Carnot cycle. Biologists use terms like phylogeny, ontology, DNA, and enzymes. Each of these terms can be considered to be the thread of a story. The principles of a field are actually a set of interwoven stories about the structure and behavior of field elements, the fabric of the multiverse.

Not moderation, but elimination is the ideal in regard to evolution-retarding habits. In a sanitarium for dope-addicts it may be advisable to allow patients temporarily a restricted — but at the same time gradually diminishing — use of narcotics. Similarly it may be advisable to condone that sex-addicts (that is to say: all those who have habituated themselves to sexual acts) do not suddenly break their habit, provided they will gradually overcome it. But no sane person can opine that a continuous use of drugs should be prescribed for the dope-addicted patients — not even in a so-called moderate degree. Still less that it should also be recommended for those who are free from the addiction. As little reasonable is it to claim that quasi moderate sexual activity must continually be indulged in by those who are addicted to such acts, and that also it should be recommended for all who are not so addicted.
C.J. Van Vliet (The Coiled Serpent: A Philosophy Of Conservation And Transmutation Of Reproductive Energy)
thus young Daniel Shipstone saw at once that the problem was not a shortage of energy but lay in the transporting of energy. Energy is everywhere—in sunlight, in wind, in mountain streams, in temperature gradients of all sorts wherever found, in coal, in fossil oil, in radioactive ores, in green growing things. Especially in ocean depths and in outer space energy is free for the taking in amounts lavish beyond all human comprehension. Those who spoke of “energy scarcity” and of “conserving energy” simply did not understand the situation. The sky was “raining soup”; what was needed was a bucket in which to carry it.

Since the moment when, at the sight of his beloved and dying brother, Levin for the first time looked at the questions of life and death in the light of the new convictions, as he called them, which between the ages of twenty and thirty-four had imperceptibly replaced the beliefs of his childhood and youth, he had been less horrified by death than by life without the least knowledge of whence it came, what it is for, why, and what it is, Organisms, their destruction, the indestructibility of matter, the law of the conservation of energy, development—the terms that had superseded these beliefs—were very useful for mental purposes; but they gave no guidance for life, and Levin suddenly felt like a person who has exchanged a thick fur coat for a muslin garment and who, being out in the frost for the first time, becomes clearly convinced, not by arguments, but with the whole of his being, that he is as good as naked and that he must inevitably perish miserably.
Leo Tolstoy (Anna Karenina)
While the living thing may easily be crushed by superior force, it none the less tries to turn the energies which act upon it into means of its own further existence. If it cannot do so, it does not just split into smaller pieces (at least in the higher forms of life), but loses its identity as a living thing. As long as it endures, it struggles to use surrounding energies in its own behalf. It uses light, air, moisture, and the material of soil. To say that it uses them is to say that it turns them into means of its own conservation. As long as it is growing, the energy it expends in thus turning the environment to account is more than compensated for by the return it gets: it grows.
John Dewey (Democracy and Education)
Another class of universal truths is the conservation laws, where the amount of some measured quantity remains unchanged no matter what. The three most important are the conservation of mass and energy, the conservation of linear and angular momentum, and the conservation of electric charge. These laws are in evidence on Earth, and everywhere we have thought to look—from the domain of particle physics to the large-scale structure of the universe. In spite of this boasting, all is not perfect in paradise. It happens that we cannot see, touch, or taste the source of eighty-five percent of the gravity we measure in the universe. This mysterious dark matter, which remains undetected except for its gravitational pull on matter we see, may be composed of exotic particles that we have yet to discover or identify. A small minority of astrophysicists, however, are unconvinced and have suggested that there is no dark matter—you just need to modify Newton’s law of gravity. Simply add a few components to the equations and all will be well. Perhaps

So what does the life of an empath look like? The short answer to this is “hiding.” Empaths often take extreme measures to contort their true identities into something less painful. They become very good at blending in and figuring out how to be loved and accepted not for who they really are but instead for how they can serve others. For example, if an empathic homosexual child is born into a very conservative family, that child will very quickly know how to suppress his true self in service to his family’s belief system. Or if an empathic, creative, energetic child is born into a family that values logic and study, the child will soon become subdued and work to prove her worth through family-approved pursuits.

Evolutionarily, the function of attachment has been to protect the organism from danger. The attachment figure, an older, kinder, stronger, wiser other (Bowlby, 1982), functions as a safe base (Ainsworth et al., 1978), and is a presence that obviates fear and engenders a feeling of safety for the younger organism. The greater the feeling of safety, the wider the range of exploration and the more exuberant the exploratory drive (i.e., the higher the threshold before novelty turns into anxiety and fear). Thus, the fundamental tenet of attachment theory: security of attachment leads to an expanded range of exploration. Whereas fear constricts, safety expands the range of exploration. In the absence of dyadically constructed safety, the child has to contend with fear-potentiating aloneness. The child will devote energy to conservative, safety enhancing measures, that is, defense mechanisms, to compensate for what's missing. The focus on maintaining safety and managing fear drains energy from learning and exploration, stunts growth, and distorts personality development.
Daniel J. Siegel (Healing Trauma: Attachment, Mind, Body and Brain (Norton Series on Interpersonal Neurobiology))
Supporting this theory is the Law of Energy Conservation, which states that energy can neither be created nor destroyed in a closed system. According to this law, all energy in the universe has already been made and our physical bodies are merely containers for our own personal energy. If the body is a container of energy, then when it dies its energy is released back into the universe the same way air is released back into the atmosphere when a balloon pops. But does it remain intact with all of its knowledge, experiences, emotions, and identity or does it simply dissipate back into the environment and lose everything that it was? This is a critical question for our field and one of the keys we all seek to unlock.
Zak Bagans (Dark World: Into the Shadows with the Lead Investigator of the Ghost Adventures Crew)
Since the moment when, at the sigh of his beloved and dying brother, Levin for the first time looked at the questions of life and death in the light of the new convictions, as he called them...he had been less horrified by death than by life without the least knowledge of whence it came, what it is for, why, and what it is. Organisms, their destruction, the indestructibility of matter, the law of the conservation of energy, development--the terms that had superseded these beliefs--were very useful for mental purposes; but they gave no guidance for life, and Levin suddenly felt like a person who has exchanged a thick fur coat fora muslin garment and who, being out in the frost for the first time, becomes clearly convinced, not by arguments, but with the whole of his being that he is as good as naked and that he must inevitably perish miserably. From that moment, without thinking about it and though he continued living as he had done heretofore, Levin never ceased to feel afraid of his ignorance...What astounded and upset him most in his connection, was that the majority of those in his set and of his age, did not see anything to be distressed about, and were quite contented and tranquil. So that, besides the principal question, Levin was tormented by other questions: were these people sincere? Were they not pretending? Or did they understand, possibly in some different or clearer way than he, the answers science gives to the questions he was concerned with?
Leo Tolstoy (Anna Karenina)
Of the three primary instinctual defense systems, the immobility state is controlled by the most primitive of the physiological subsystems. This neural system (mediated by the unmyelinated portion of the vagus nerve) controls energy conservation and is triggered only when a person perceives that death is imminent—whether from outside, in the form of a mortal threat, or when the threat originates internally, as from illness or serious injury. Both of these challenges require that one hold still and conserve one’s vital energy. When this most archaic system dominates, one does not move; one barely breathes; one’s voice is choked off; and one is too scared to cry. One remains motionless in preparation for either death or cellular restitution.
Peter A. Levine
Planck understood that Clausius was not simply stating the obvious, but something of deep significance. Heat, the transfer of energy from A to B due to a temperature difference, explained such everyday occurrences as a hot cup of coffee getting cold and an ice cube in a glass of water melting. But left undisturbed, the reverse never happened. Why not? The law of conservation of energy did not forbid a cup of coffee from getting hotter and the surrounding air colder, or the glass of water becoming warmer and the ice cooler. It did not outlaw heat flowing from a cold to a hot body spontaneously. Yet something was preventing this from happening. Clausius discovered that something and called it entropy. It lay at the heart of why some processes occur in nature and others do not.
Manjit Kumar (Quantum: Einstein, Bohr and the Great Debate About the Nature of Reality)
The second was the chapter in Roger Penrose’s book The Emperor’s New Mind in which he discusses entropy. He points out that there’s a sense in which it’s incorrect to say we eat food because we need the energy it contains. The conservation of energy means that it is neither created nor destroyed; we are radiating energy constantly, at pretty much the same rate that we absorb it. The difference is that the heat energy we radiate is a high-entropy form of energy, meaning it’s disordered. The chemical energy we absorb is a low-entropy form of energy, meaning it’s ordered. In effect, we are consuming order and generating disorder; we live by increasing the disorder of the universe. It’s only because the universe started in a highly ordered state that we are able to exist at all.
Ted Chiang (Exhalation)
Dark matter is currently thought to make up about 23 percent of the mass and energy of the universe, whereas normal matter and energy make up only about 4 percent. Worse still, most contemporary cosmologists think that the continuing expansion of the universe is driven by “dark energy,” whose nature is again obscure. According to the Standard Model of cosmology, dark energy currently accounts for about 73 percent of the matter and energy of the universe. How do dark matter and energy relate to regular matter and energy? And what is the zero-point energy field, also known as the quantum vacuum? Can any of this zero-point energy be tapped? The law of conservation of matter and energy was formulated before these questions arose, and has no ready answer for them. It is based on philosophical and theological theories. Historically, it is rooted in the atomistic school of philosophy in ancient Greece. From the outset it was an assumption. In its modern form, it combines a series of “laws” that have developed since the seventeenth century—the laws of conservation of matter, mass, motion, force and energy. In this chapter I look at the history of these ideas, and show how modern physics throws up questions that the old theories cannot answer. As faith in conservation comes into question, astonishing new possibilities open up in realms ranging from the generation of energy to human nutrition.
Rupert Sheldrake (Science Set Free: 10 Paths to New Discovery)
You want a physicist to speak at your funeral. You want the physicist to talk to your grieving family about the conservation of energy, so they will understand that your energy has not died. You want the physicist to remind your sobbing mother about the first law of thermodynamics; that no energy gets created in the universe, and none is destroyed. You want your mother to know that all your energy, every vibration, every Btu of heat, every wave of every particle that was her beloved child remains with her in this world. You want the physicist to tell your weeping father that amid energies of the cosmos, you gave as good as you got. And at one point you’d hope that the physicist would step down from the pulpit and walk to your brokenhearted spouse there in the pew and tell him that all the photons that ever bounced off your face, all the particles whose paths were interrupted by your smile, by the touch of your hair, hundreds of trillions of particles, have raced off like children, their ways forever changed by you. And as your widow rocks in the arms of a loving family, may the physicist let her know that all the photons that bounced from you were gathered in the particle detectors that are her eyes, that those photons created within her constellations of electromagnetically charged neurons whose energy will go on forever. And the physicist will remind the congregation of how much of all our energy is given off as heat. There may be a few fanning themselves with their programs as he says it. And he will tell them that the warmth that flowed through you in life is still here, still part of all that we are, even as we who mourn continue the heat of our own lives. And you’ll want the physicist to explain to those who loved you that they need not have faith; indeed, they should not have faith. Let them know that they can measure, that scientists have measured precisely the conservation of energy and found it accurate, verifiable and consistent across space and time. You can hope your family will examine the evidence and satisfy themselves that the science is sound and that they’ll be comforted to know your energy’s still around. According to the law of the conservation of energy, not a bit of you is gone; you’re just less orderly. Amen.

The organic and inorganic structures supporting human life are changing. Breathtaking technological developments, coupled with rapid advances in medicine, supported a dramatic explosion in the human population worldwide. Increases in human population placed pressure upon the habitat. Lack of foresight and commercial ogres fused to a consumptive consumer mentality fostered a radical reduction in habitat for other creatures and spawned a predictable environmental crisis. Commercial enterprises nimbly renamed the “environmental crisis” the “energy crisis,” effectively downplaying the dramatic cost inflicted upon the ecosystem in the name of preserving cheap energy sources for Americans. We live on the brink of impending disaster. Nonetheless, we must carry on. It is humankind’s greatest challenge to place our self-gratification in check in order to ensure that our species and other creatures survive the violent onslaught raging against the ecosystem. Despite the rapid expansion of new technology, which alters how human beings live and communicate with each other, the fundamental challenge of humanity remains consistent. Every generation must address how to live a purposeful life, one filled with joy and contentment.

In the vestibule of the Manchester Town Hall are placed two life-sized marble statues facing each other. One of these is that of John Dalton ... the other that of James Prescott Joule. ... Thus the honour is done to Manchester's two greatest sons—to Dalton, the founder of modern Chemistry and of the atomic theory, and the laws of chemical-combining proportions; to Joule, the founder of modern physics and the discoverer of the Law of Conservation of Energy. One gave to the world the final proof ... that in every kind of chemical change no loss of matter occurs; the other proved that in all the varied modes of physical change, no loss of energy takes place.

As the Haitian proverb puts it: Behind mountains are more mountains. Elysium is a myth. One does not overcome an obstacle to enter the land of no obstacles. On the contrary, the more you accomplish, the more things will stand in your way. There are always more obstacles, bigger challenges. You’re always fighting uphill. Get used to it and train accordingly. Knowing that life is a marathon and not a sprint is important. Conserve your energy. Understand that each battle is only one of many and that you can use it to make the next one easier. More important, you must keep them all in real perspective. Passing one obstacle simply says you’re worthy of more. The world seems to keep throwing them at you once it knows you can take it. Which is good, because we get better with every attempt.
Ryan Holiday (The Obstacle is the Way: The Timeless Art of Turning Adversity to Advantage)
Einstein’s “physical strategy” began with his mission to generalize the principle of relativity so that it applied to observers who were accelerating or moving in an arbitrary manner. Any gravitational field equation he devised would have to meet the following physical requirements: • It must revert to Newtonian theory in the special case of weak and static gravitational fields. In other words, under certain normal conditions, his theory would describe Newton’s familiar laws of gravitation and motion. • It should preserve the laws of classical physics, most notably the conservation of energy and momentum. • It should satisfy the principle of equivalence, which holds that observations made by an observer who is uniformly accelerating would be equivalent to those made by an observer standing in a comparable gravitational field.
Walter Isaacson (Einstein: His Life and Universe)
Man is the first product of evolution to be capable of controlling evolutionary destiny.'" Endowed as he is with reasoning powers, he must independently decide up on his own behavior, without the compelling guidance by instinct. Supplied with mind, he is expected to cooperate consciously with nature in her further evolutionary program. Unfortunately humanity has arrantly failed to make a serious effort to promote its own further progress. Instead of using the power of the mind to understand the responsibilities which freedom from blind obedience to instinct entails, mankind has refused to listen whenever it was reminded of the requirements of the evolutionary law. It was so much easier to lend an ear to the promptings of desire, which was an unknown element up to the human stage. It must have been very soon after the acquisition of mental self-consciousness and his becoming aware of stirrings of primitive impulses, that man began to use the mind to stimulate the desires of the body. In this way he has indulged the almost negligible sexual impulse which he inherited from the animal kingdom, until it has become a desire so strong that he has difficulty to control it. Overstimulated by this unnaturally strong desire of his own making, man has looked for arbitrary ways in which to gratify it. Although reducing actual reproduction, he has discovered ways of unreproductive sexual action. But every such act, whatever form it takes, is a misuse of sex and uses up some of the life force that should be utilized for the support and the development of higher faculties. "The record of our race progress clearly shows how our upward movement has been checked ... by that misuse.

Three laws governing black hole changes were thus found, but it was soon noticed that something unusual was going on. If one merely replaced the words 'surface area' by 'entropy' and 'gravitational field' by 'temperature', then the laws of black hole changes became merely statements of the laws of thermodynamics. The rule that the horizon surface areas can never decrease in physical processes becomes the second law of thermodynamics that the entropy can never decrease; the constancy of the gravitational field around the horizon is the so-called zeroth law of thermodynamics that the temperature must be the same everywhere in a state of thermal equilibrium. The rule linking allowed changes in the defining quantities of the black hole just becomes the first law of thermodynamics, which is more commonly known as the conservation of energy.
John D. Barrow (Theories of Everything: The Quest for Ultimate Explanation)
Einstein’s “mathematical strategy,” on the other hand, focused on using generic mathematical knowledge about the metric tensor to find a gravitational field equation that was generally (or at least broadly) covariant. The process worked both ways: Einstein would examine equations that were abstracted from his physical requirements to check their covariance properties, and he would examine equations that sprang from elegant mathematical formulations to see if they met the requirements of his physics. “On page after page of the notebook, he approached the problem from either side, here writing expressions suggested by the physical requirements of the Newtonian limit and energy-momentum conservation, there writing expressions naturally suggested by the generally covariant quantities supplied by the mathematics of Ricci and Levi-Civita,” says John Norton.
Walter Isaacson (Einstein: His Life and Universe)
In order to verify the conservation of energy, we must be careful that we have not put any in or taken any out. Second, the energy has a large number of different forms, and there is a formula for each one. These are: gravitational energy, kinetic energy, heat energy, elastic energy, electrical energy, chemical energy, radiant energy, nuclear energy, mass energy. If we total up the formulas for each of these contributions, it will not change except for energy going in and out. It is important to realize that in physics today, we have no knowledge of what energy is. We do not have a picture that energy comes in little blobs of a definite amount. It is not that way. However, there are formulas for calculating some numerical quantity, and when we add it all together it gives "28"'—always the same number. It is an abstract thing in that it does not tell us the mechanism or the reasons for the various formulas.
Richard P. Feynman (The Feynman Lectures on Physics)
In the past, people practiced the Tao, the Way of Life. They understood the principle of balance as represented by the transformations of the energies of the universe. They formulated exercises to promote energy flow to harmonize themselves within the universe. They ate a balanced diet at regular times, arose and retired at regular hours, avoided over stressing their bodies and minds, and refrained from overindulgence of all kinds. They maintained well-being of body and mind; thus, it is not surprising that they lived over one hundred years.“These days, people have changed their way of life. They drink wine as though it were water, indulge excessively in destructive activities, drain their jing – the body’s essence that is stored in the Kidneys – and deplete their qi. They do not know the secret of conserving their energy and vitality. Seeking emotional excitement and momentary pleasures, people disregard the natural rhythm of the universe. They fail to regulate their lifestyle and diet, and sleep improperly. So it is not surprising that they look old at fifty and die soon after.
Maoshing Ni (The Yellow Emperor's Classic of Medicine: A New Translation of the Neijing Suwen with Commentary)
The German mathematician Emmy Noether proved in 1915 that each continuous symmetry of our mathematical structure leads to a so-called conservation law of physics, whereby some quantity is guaranteed to stay constant-and thereby has the sort of permanence that might make self-aware observers take note of it and give it a "baggage" name. All the conserved quantities that we discussed in Chapter 7 correspond to such symmetries: for example, energy corresponds to time-translation symmetry (that our laws of physics stay the same for all time), momentum corresponds to space-translation symmetry (that the laws are the same everywhere), angular momentum corresponds to rotation symmetry (that empty space has no special "up" direction) and electric charge corresponds to a certain symmetry of quantum mechanics. The Hungarian physicist Eugene Wigner went on to show that these symmetries also dictated all the quantum properties that particles can have, including mass and spin. In other words, between the two of them, Noether and Wigner showed that, at least in our own mathematical structure, studying the symmetries reveals what sort of "stuff" can exist in it.
Max Tegmark (Our Mathematical Universe: My Quest for the Ultimate Nature of Reality)
The same effort to conserve force was also evident in war, at the tactical level. The ideal Roman general was not a figure in the heroic style, leading his troops in a reckless charge to victory or death. He would rather advance in a slow and carefully prepared march, building supply roads behind him and fortified camps each night in order to avoid the unpredictable risks of rapid maneuver. He preferred to let the enemy retreat into fortified positions rather than accept the inevitable losses of open warfare, and he would wait to starve out the enemy in a prolonged siege rather than suffer great casualties in taking the fortifications by storm. Overcoming the spirit of a culture still infused with Greek martial ideals (that most reckless of men, Alexander the Great, was actually an object of worship in many Roman households), the great generals of Rome were noted for their extreme caution. It is precisely this aspect of Roman tactics (in addition to the heavy reliance on combat engineering) that explains the relentless quality of Roman armies on the move, as well as their peculiar resilience in adversity: the Romans won their victories slowly, but they were very hard to defeat. Just as the Romans had apparently no need of a Clausewitz to subject their military energies to the discipline of political goals, it seems that they had no need of modern analytical techniques either. Innocent of the science of systems analysis, the Romans nevertheless designed and built large and complex security systems that successfully integrated troop deployments, fixed defenses, road networks, and signaling links in a coherent whole.

Dunyasha lunged. Inej stayed close, using every opportunity to keep inside the mercenary’s guard and deny her the advantage of her longer reach. She was stronger than she’d been when they’d faced each other on the wire, well rested, well fed. But she was still a girl trained on the streets, not in the towers of some Shu monastery. Inej’s first mistake was a slow recoil. She paid for it in a deep slash to her left bicep. It cut through the padding and made it hard to keep a good grip on the blade in her left hand. Her second error was putting too much force into an upward jab. She leaned in too far and felt Dunyasha’s knife skim her ribs. A shallow cut that time, but it had been a close thing. She ignored the pain and focused on her opponent, remembering what Kaz had told her. Find her tells. Everyone has them. But Dunyasha’s movements seemed unpredictable. She was equally comfortable with her left and right hands, she favored neither foot, and waited until the last moment to strike, giving no early indication of her intent. She was extraordinary. “Growing weary, Wraith?” Inej said nothing, conserving her energy. Though Dunyasha’s breathing seemed clear and even, Inej could feel herself dragging slightly. It wasn’t much, but it was enough to give the mercenary the advantage. Then she saw it—the slightest hitch of Dunyasha’s chest, followed by a lunge. A hitch, then another lunge. The tell was in her breathing. She took in a deep breath before an attack. There. Inej dodged left, struck quickly, a rapid jab of her blade to Dunyasha’s side. There. Inej attacked again, and blood flowered on Dunyasha’s arm. Inej drew back, waited as the girl advanced. The mercenary liked to hide her direct assaults with other movement, the whirl of her blades, an unnecessary flourish. It made her hard to read, but there. The quick burst of breath. Inej sank low and swept her left leg wide, knocking the mercenary off balance. This was her chance. Inej shot to her feet, using her upward momentum and Dunyasha’s descent to shove her blade under the leather guard protecting the girl’s sternum. Inej felt blood on her hand as she wrenched the knife free and Dunyasha released a shocked grunt. The girl stared at her now, clutching her chest with one hand. Her eyes narrowed. There was still no fear there, only a hard, bright resentment, as if Inej had ruined an important party. “The blood you spill is the blood of kings,” seethed Dunyasha. “You are not fit for such a gift.” Inej almost felt sorry for her.
