I used to masturbate onto birds at a local park. Not a thing that I'm particularly proud of but I became quite good at it. I was taking zinc supplements so I was shooting massive loads and it became something of a sport to me. For anyone interested here is your best strategy, first, you need to find an isolated spot so you don't become a sex offender. I found a short kind of channel area where I saw the pigeons would congregate. Next, you arouse yourself. I was usually content with envisioning the occasional jogging lady coming over and taking a shit on my chest and that was enough to fuel the fire but if you're not as sexually
charged as me just take some porn on the go. After you're good an horny, you get some bread. My pigeons preferred white bread but healthier birds might have a taste for honey wheat or maybe even multigrain. Fat, unhealthy birds are slower and easier to hit so remember that. Once you are seated on the bench and ready to do the deed, whip your roosevelt out and scatter bread out within a few feet of you. Use your
judgement based on how far you know you can cum. I was a lonely and depraved soul who could hit targets
the size of a thimble at distances up to 4 feet. You wait for the pigeons to begin eating and to get comfortable
with your presence. At this point, you want to coo gently and talk sensually to them to gain their trust. Now you're finally ready to cum on your bird. This is a tough part because the rapid motion of masturbation is very frightening to the birds, so you have to be subtle. Once you master a technique, you simply wind it up and let it go, aiming depending on your past cumming experiences. I always came high so I would aim for the neck of the bird and catch it right in the face. It's an extremely satisfying and erotic feeling, seeing those birds reel around covered in cum and maybe even transporting it to other places in the city.

"I have a dream.... That one day every person playing these games will control their own rolls. A fandom of the truly free, dammit! A fandom of choice, not rng, ruled by Meta, not luck! Where the Gacha changes to suit the individual, not the other way around! Where powercreep and 3 turn kills are back where they belong: in the hands of the players! Where every player is free to play - to roll - for himself!
Fuck all these limp-dick Lasangas and chickenshit MiHoyos! Fuck this 24-hour Internet spew of Youtube Must Rolls and saving bullshit! Fuck Luck EX pride! Fuck the guides! FUCK ALL OF IT! Gacha is diseased. Rotten to the core. There's no saving it - we need to pull it out by the Waifus. Wipe the slate clean. BURN IT DOWN! And from the ashes, a new Gacha will be born. Evolved, but untamed! The weak will be purged and the strongest will thrive - free to play as they see fit, they'll make Gachas great again!...
In my new Gacha, people will Challenge Quest and get stuck because of what they PLAY! Not for money. not for spamming threads asking if they should roll! Not for what they're told is right. Every player will be free to game his own way!"
"Why so many people can keep going with shitty relationship" don't you ever think about that? Research found that's because The Sunk Cost Fallacy, someone who already investing any time, money, and effort to anything doesn't want everything wasted even if they would suffer. For me, that a stupid thing I've ever heard. If you don't like it, then leave it. Just like me, i leave everything for my beloved Projekt Red. The only one i need just her cute smile by my side.
What you said?? Projekt Red isn't exist??? Shut the fuk up cunt, you don't even know bout love, you doesn't ever have a proper relationship with real women!!! So yeah, get GF first before you talk to me again you stupid doughnut!!
The unenlightened masses
They cannot make the judgement call
Give up free will forever their voices won't be heard at all
Display obedience
While never stepping out of line
And blindly swear allegiance
Let your country control your mind
(Let your country control your soul)
Live in ignorance
And purchase your happiness
When blood and sweat is the real cost
Thinking ceases, the truth is lost
Don't you worry
You'll be told exactly what to do
I give my people the lives they need
The righteous will succeed
The fires of greed will burn the weak
So we'll make freedom obsolete
Making whole the fabric of society
Collective consciousness controlled as you will see
Let your country control your soul
Let your country control your soul
Let your country control your soul
Let your country control your soul
Suisei starts streaming as you're getting ready to go to bed. You join for a few minutes just to type "shotacon" in chat before turning in for the night. 3am, you hear a loud crashing sound coming from your front door. A dark figure walks in and into your bedroom. It's Suisei, the idol who you had grown fond of since her debut with hololive straddles you, grabbing your neck with her left hand and punching your head with her right. She whispers, "Tell me what you said kiddo, or I won't stop until this head splits open~musical_note" Still dopey, you cannot say a word as she chokes you. As she increased the strength used with each punch, you feel pain shoot through your head, you are struggling to stay conscious as you fight to break free from her grip. You suddenly feel as if you have a chance as you are finally able to push her hand out of the way. Only for her to sink the hardest punch of all straight into your face. You feel your eye sockets loosening, the cartilage in your nose snapping, your jaws coming loose and your skull caving in as the idols bloody fist sank deep into your face. You hear the laugh you once thought was adorable in its own way now ringing in your ears as the battlecry of a true psychopath before losing consciousness there and then. You collapse back onto your bed as the comet continues pounding your mangled head with her fist. Not even a minute passes before her punches break through the skin and split your lifeless head open, spewing mangled remains of brain matter, blood vessels and pieces of skull all over the place. The suicopath grins as she has a taste of your blood on her fist before carrying your now headless body out of your house and into a pickup truck. She drives for hours to a secluded island off the shore and dumps your body into the ocean. Whispering, "Goodbye, Stargazer~"
Standing here I realize You are just like me Trying to make history But who's to judge The right from wrong When our guard is down I think we'll both agree That Violence breeds violence But in the end it has to be this way I've carved my own path You followed your wrath But maybe we're both the same The world has turned And so many have burned But nobody is to blame Yet staring across this barren wasted land I feel new life will be born Beneath the blood stained sand Beneath the blood stained sand
I'm [Unknown] , a normal second-year student in high school. Perfectly normal, if not for the fact that everyone avoids me like the plague because I look like I'm out for blood. The only exception is the typical novel protagonist chad [Who?]. But one day, his sister Touka confessed to me! This chick just met me yesterday, what's she going on about?! In any case, I decided to be her fake boyfriend on account of my friendship with Haruba. But now even [Who?]'s idol-tier childhood friend and a smoking hot teacher is getting involved with me?! Hold up, this ain't a romcom wet dream! I mean, there's no way a sidekick like me could be popular, right?
Game Show Idea:
11 gay men and 1 straight man are locked in a house. The object for the gay men is to find out who isn't gay. Once a week someone gets outvoted, until 2 are left, or the straight man is out. If the gays manage to outvote him, they win 1 million dollars. If the straight man is among the 2 last people in the house in the end, he wins 1 million dollars.
Quantum mechanics allows the calculation of properties and behaviour of physical systems. It is typically applied to microscopic systems: molecules, atoms and sub-atomic particles. It has been demonstrated to hold for complex molecules with thousands of atoms,[4] but its application to human beings raises philosophical problems, such as Wigner's friend, and its application to the universe as a whole remains speculative.[5] Predictions of quantum mechanics have been verified experimentally to an extremely high degree of accuracy.[note 1]
A fundamental feature of the theory is that it usually cannot predict with certainty what will happen, but only give probabilities. Mathematically, a probability is found by taking the square of the absolute value of a complex number, known as a probability amplitude. This is known as the Born rule, named after physicist Max Born. For example, a quantum particle like an electron can be described by a wave function, which associates to each point in space a probability amplitude. Applying the Born rule to these amplitudes gives a probability density function for the position that the electron will be found to have when an experiment is performed to measure it. This is the best the theory can do; it cannot say for certain where the electron will be found. The Schrödinger equation relates the collection of probability amplitudes that pertain to one moment of time to the collection of probability amplitudes that pertain to another.
One consequence of the mathematical rules of quantum mechanics is a tradeoff in predictability between different measurable quantities. The most famous form of this uncertainty principle says that no matter how a quantum particle is prepared or how carefully experiments upon it are arranged, it is impossible to have a precise prediction for a measurement of its position and also at the same time for a measurement of its momentum.
Another consequence of the mathematical rules of quantum mechanics is the phenomenon of quantum interference, which is often illustrated with the double-slit experiment. In the basic version of this experiment, a coherent light source, such as a laser beam, illuminates a plate pierced by two parallel slits, and the light passing through the slits is observed on a screen behind the plate.[6]: 102–111 [2]: 1.1–1.8 The wave nature of light causes the light waves passing through the two slits to interfere, producing bright and dark bands on the screen – a result that would not be expected if light consisted of classical particles.[6] However, the light is always found to be absorbed at the screen at discrete points, as individual particles rather than waves; the interference pattern appears via the varying density of these particle hits on the screen. Furthermore, versions of the experiment that include detectors at the slits find that each detected photon passes through one slit (as would a classical particle), and not through both slits (as would a wave).[6]: 109 [7][8] However, such experiments demonstrate that particles do not form the interference pattern if one detects which slit they pass through. Other atomic-scale entities, such as electrons, are found to exhibit the same behavior when fired towards a double slit.[2] This behavior is known as wave–particle duality.
Another counter-intuitive phenomenon predicted by quantum mechanics is quantum tunnelling: a particle that goes up against a potential barrier can cross it, even if its kinetic energy is smaller than the maximum of the potential.[9] In classical mechanics this particle would be trapped. Quantum tunnelling has several important consequences, enabling radioactive decay, nuclear fusion in stars, and applications such as scanning tunnelling microscopy and the tunnel diode.[10]
When quantum systems interact, the result can be the creation of quantum entanglement: their properties become so intertwined that a description of the whole solely in terms of the individual parts is no longer possible. Erwin Schrödinger called entanglement "...the characteristic trait of quantum mechanics, the one that enforces its entire departure from classical lines of thought".[11] Quantum entanglement enables the counter-intuitive properties of quantum pseudo-telepathy, and can be a valuable resource in communication protocols, such as quantum key distribution and superdense coding.[12] Contrary to popular misconception, entanglement does not allow sending signals faster than light, as demonstrated by the no-communication theorem.[12]
Another possibility opened by entanglement is testing for "hidden variables", hypothetical properties more fundamental than the quantities addressed in quantum theory itself, knowledge of which would allow more exact predictions than quantum theory can provide. A collection of results, most significantly Bell's theorem, have demonstrated that broad classes of such hidden-variable theories are in fact incompatible with quantum physics. According to Bell's theorem, if nature actually operates in accord with any theory of local hidden variables, then the results of a Bell test will be constrained in a particular, quantifiable way. Many Bell tests have been performed, using entangled particles, and they have shown results incompatible with the constraints imposed by local hidden variables.[13][14]
It is not possible to present these concepts in more than a superficial way without introducing the actual mathematics involved; understanding quantum mechanics requires not only manipulating complex numbers, but also linear algebra, differential equations, group theory, and other more advanced subjects.[note 2] Accordingly, this article will present a mathematical formulation of quantum mechanics and survey its application to some useful and oft-studied examples.
The laws of thermodynamics define a group of physical quantities, such as temperature, energy, and entropy, that characterize thermodynamic systems in thermodynamic equilibrium. The laws also use various parameters for thermodynamic processes, such as thermodynamic work and heat, and establish relationships between them. They state empirical facts that form a basis of precluding the possibility of certain phenomena, such as perpetual motion. In addition to their use in thermodynamics, they are important fundamental laws of physics in general, and are applicable in other natural sciences.
Traditionally, thermodynamics has recognized three fundamental laws, simply named by an ordinal identification, the first law, the second law, and the third law.[1][2][3] A more fundamental statement was later labelled as the zeroth law, after the first three laws had been established.
The zeroth law of thermodynamics defines thermal equilibrium and forms a basis for the definition of temperature: If two systems are each in thermal equilibrium with a third system, then they are in thermal equilibrium with each other.
The first law of thermodynamics states that, when energy passes into or out of a system (as work, heat, or matter), the system's internal energy changes in accord with the law of conservation of energy.
The second law of thermodynamics states that in a natural thermodynamic process, the sum of the entropies of the interacting thermodynamic systems never decreases. Another form of the statement is that heat does not spontaneously pass from a colder body to a warmer body.
The third law of thermodynamics states that a system's entropy approaches a constant value as the temperature approaches absolute zero. With the exception of non-crystalline solids (glasses) the entropy of a system at absolute zero is typically close to zero.[2]
The first and second laws prohibit two kinds of perpetual motion machines, respectively: the perpetual motion machine of the first kind which produces work with no energy input, and the perpetual motion machine of the second kind which spontaneously converts thermal energy into mechanical work.
The history of thermodynamics is fundamentally interwoven with the history of physics and history of chemistry and ultimately dates back to theories of heat in antiquity. The laws of thermodynamics are the result of progress made in this field over the nineteenth and early twentieth centuries. The first established thermodynamic principle, which eventually became the second law of thermodynamics, was formulated by Sadi Carnot in 1824 in his book Reflections on the Motive Power of Fire. By 1860, as formalized in the works of scientists such as Rudolf Clausius and William Thomson, what are now known as the first and second laws were established. Later, Nernst's theorem (or Nernst's postulate), which is now known as the third law, was formulated by Walther Nernst over the period 1906–12. While the numbering of the laws is universal today, various textbooks throughout the 20th century have numbered the laws differently. In some fields, the second law was considered to deal with the efficiency of heat engines only, whereas what was called the third law dealt with entropy increases. Gradually, this resolved itself and a zeroth law was later added to allow for a self-consistent definition of temperature. Additional laws have been suggested, but have not achieved the generality of the four accepted laws, and are generally not discussed in standard textbooks.
The zeroth law of thermodynamics provides for the foundation of temperature as an empirical parameter in thermodynamic systems and establishes the transitive relation between the temperatures of multiple bodies in thermal equilibrium. The law may be stated in the following form:
If two systems are both in thermal equilibrium with a third system, then they are in thermal equilibrium with each other.[4]
Though this version of the law is one of the most commonly stated versions, it is only one of a diversity of statements that are labeled as "the zeroth law". Some statements go further, so as to supply the important physical fact that temperature is one-dimensional and that one can conceptually arrange bodies in a real number sequence from colder to hotter.[5][6][7]
These concepts of temperature and of thermal equilibrium are fundamental to thermodynamics and were clearly stated in the nineteenth century. The name 'zeroth law' was invented by Ralph H. Fowler in the 1930s, long after the first, second, and third laws were widely recognized. The law allows the definition of temperature in a non-circular way without reference to entropy, its conjugate variable. Such a temperature definition is said to be 'empirical'.[8][9][10][11][12][13]
Day 1: I have successfully secured Reimu inside a bullet proof jar. Thankfully she has no lives or bombs left so she cannot cheat her way out of this situation. The container is 6 foot tall but has a small opening at the top to prevent her from suffocating; though air is still rare in there. It has been three hours that Reimu has tried in vain to break out of her jar. Because she seemed so tired, I decided to start the experiment by pouring some of my seeds (one gallon) inside the container to feed her some precious vitamins. As she powerlessly looked in horror at the small amount of liquid food that started pouring onto her, she vainly tried to cover her face to prevent the juice from getting in her eyes. Her clothes, turned transparent and half white from the fluids that came from my manhood; stuck to her frail figure. Apparently not able to assimilate the nutrients, Reimu was taken by violent gaggings and started puking on herself. The two fluids blended into a yellowish mix that was one inch deep in the bottom of the jar; splattering and sticking on Reimu's shoes like a blob of slime.
Day 2: It has been 28 hours since Reimu has been imprisoned inside the cum jar. Though her eyes seem to be irritated from crying and the atmosphere of the jar, she seems to still be healthy enough to live for at least a week thanks to her divine protection. For this day, I decided to change her food and replace it with an old sample of my semen, which dates back to three years ago. Because of it's old age, it was semi-solid; like guacamole.Opening the vent at the top of her jar, I was welcomed by the terrorized cries of Reimu, who looked dreadfully at the container I was carrying.I poured down the clumps of fermented sperm onto her, which must have amounted for a total of 10 gallons. Panicked, Reimu attempted to remove the seed pâté from her body; but because of it's texture, it just kept on spreading on her clothes and under her fingernails. Reimu's face; twisted from the horror she was experiencing, started gagging in vain, as her spasming stomach was empty thanks to her stubbornness of not eating my fresh seeds. Feeling her strength leaving her body, she fell onto her knees into the muddy mass quicksand of semen which now reached up to the bottom of her breasts.
Day 5: After leaving her to rest for three days, I came back to an unconscious reimu with dark eyebags and dried lips; her face completely covered with a crusty layer of semen which looked like an excessively dried face mask. Not sure whether she was still alive or not; and not wanting to give her a chance to escape, I started adding a large dose of semen to see if she would react once her face was below surface. Though not reacting at first, she started opening her eyes when the gooey mass started reaching her neck.As if her instinct to live suddenly kicked in, a large dose of Adrenalin started rushing through her veins as she tried to stand up as fast as she could, only to slip up and fall head first into the sperm. Quickly, she got back up and lied on the wall of her jar, coughing because of the sudden intake of semen through her throat and nose. I kept on pouring. The level was now reaching her chin when she stood up on her toes. I decided to leave it at that, and to just observe her for the next 15 hours, as she struggled to stay awake because of her lack of sleep and food intake. Finally, she found a way to stand up and lie on the wall of the jar to sleep, leaving only her mouth underneath the sea of sperm.
Day 6: I decided to make a surprise to Reimu for hanging on for so long without eating any of my semen. Her lifeless eyes greeted me, while her head kept tilting backward and forward; indicating that she was shortly falling asleep for a few seconds out of exhaustion.I opened the top of the jar, knowing full well that she wasn't in condition to escape from the jar. Tied to a thin rope, I carefully let down a piece of raw meat to the level of her face, making sure it was intact from my semen. Reimu's eyes lit up, as raw meat was a godsent in this situation for her. She violently started tearing parts of the raw meat and gulped it down in minutes. What she didn't know, however, was that it freshly came out of the body of Kaguya Houraisan; who was locked down in another room inside my mansion. Eating the raw liver of an immortal is, after all, a way to transfer one's immortality to another. Thankfully, being immortal didn't mean that she stopped feeling pain, far from it.Satisfied, I went back to pick up a barrel of sperm to fill the rest of her jar. I must admit that I giggled when I saw the sudden drop in hope on her face when she witnessed what was coming for her. As if the last bits of her sanity crumbled, she let out a chilling scream and started banging on the walls of her jar, in vain. The violence behind each one of her hits was enough to break her bones and leave blood on the wall, but the wounds on her body healed up almost instantly. She started trying to choke herself with her own hands, but while she did feel the pain of suffocating and having her throat crushed, she wouldn't die. I began pouring. As the level rose, her cries for help and mercy gradually sounded like she was talking underwater, which was actually the case, but with semen.I stopped pouring once the level was 3 inches away from the top of the jar; leaving just enough room to give her the hope of breathing air.After watching her struggle for 3 hours and 45 minutes to make sure.
"The Return by Death that you possess is an incredible Authority. You do not comprehend how it is truly to be used. You can redo the world any number of times before you arrive at the result that you desire. To a researcher, this is the ultimate ideal manifesting in physical form. Is that not so? By rights, you should only be able to obtain one result for any particular thing. You can make excessive amounts of varied deductions and suppositions about the results. But there is usually but a single result. You can never repeat the exact same conditions in search of a different result. The conditions all shift: time, environment, memory, procedures. 'Back then, if I'd only changed one thing, the results would be different.' This is not in the realm of ideals but of dreams and delusions. Because I have the heart of a researcher, your Authority truly makes my mouth water. With 'identical conditions' and 'verification of differences' secured, one can identify a 'proper result' and a 'variant result.' How could I not covet that? With it before me, how could I not test various possibilities? Of course, I will not coerce you to use Return by Death. You will use that power for the sake of the result you desire. And I shall lend my wit as much as you please so that your desire might be granted. I have high hopes that the great many results that shall be borne from this shall serve to satisfy my inquisitive mind. No one would punish a girl for wanting such a small thing, surely? Your desire for a future and my curiosity shall be satisfied together. Perhaps this makes you uneasy, for I do not know the future, either. I will not purposefully lead you to a mistaken future in order to test the results. All Unknowns are equal before me. By mulling and struggling against the same problems, the answer will come. This makes necessary the highest form of relationship between us. I swear I shall protect you with all my heart. But that does not change the fact that I cannot interfere with reality. If a physical obstacle stands before you, I can expect that challenging it will break your mind and body many times over. If it comes to that, I genuinely intend to exert my every power to protect your mind. I will not tell you there are no ulterior motives involved in that. But I don't want you to think that I am calculating everything because of my inquisitive mind. I do think fondly of you, and it is a fact that my maidenly heart wishes to be of aid to you. I am repeating myself, but you and I are ideally compatibility. I can say it plainly. I will use your power, and you will use me for the sake of your 'optimal future.' It is my genuine desire to be a woman used for your own convenience. Though it would only be in this dream world, should you desire it, I do not mind using this body of mine to comfort you. I shall happily grant it to you. Oh my, that might not be the best thing for the people you care for, that silver-haired half-elf and that blue-haired demon…they who you have sworn to save and protect without fail. Not that I can claim any particular opinion toward them, but at any rate, please take it as expressing how strong, how unshakable my feelings are. Many difficulties shall befall you in the future as well. Your resolve shall lead you to challenge them, but that is tragic. I will become the beacon that lights your path. So, too, will I be the bonds you wish to protect. Your questions, your burdens, your feelings, your hopes…unexpectedly, through the Trial, you have taught me just how much value these things hold. Certainly, to you, the scenes you saw might have been Hell itself. But given the choice between knowing beforehand and ignorance, I wish to praise the will to learn even such tragic facts. With these serving as your gruel, you shall stretch a hand toward the future, even at the cost of your life. That Trial was necessary so that you might learn there might be sacrifices made for that future's sake. As you use Return by Death more and more, perhaps your emotions might fray, perhaps the deaths of people precious to you might fail to move your heart, but most of all, you might have to lose some part of yourself in order to arrive at the place at which you are destined to reach. The Trial prevented that end. I did that, in order to protect you. If those scenes pained your heart, putting you on the verge of breaking, I do not exaggerate in saying I did it for that sake. Because it would serve as the linchpin for your moving forward, I accepted it. With my words, I shall grant you the strength to advance forward. I will console you, I will scold you, I will even love you. Or if it is hatred you require, I will devote that to you, all for you. You like girls who devote themselves to you, yes? You need me. By yourself, you cannot grasp the future. It is none other than I who is the most suitable girl for you. —You need me. And I need you. Already, there is none other than you who can satisfy my curiosity. I mean, I've already discovered you. You broadened my world. Through you, I, said to be the Witch bearing the greatest intellect in the world, have tasted the fruit of the Unknown once more. If you want to use that power to save someone, then save me. Having even the crumbs of that noble thought is enough for me. Please. I want you to trust me. Perhaps you think I deceived you because of the fact that I did not expose enough of what I truly thought beforehand. I wanted to get the timing right. If I exposed these feelings while our relationship was still shallow, you would probably have pushed me away. I did not want that. I could not endure that. That goes for you too, yes? If you lost me as a collaborator, your heart would surely be broken. We are both working toward our optimal ends. And I know what that optimal end is. I can help you. Through infinite trial runs, you will arrive at the future, albeit with your heart worn down and scarred by the ordeal. Let me do this. I will never betray your trust. Certainly, my heart might be attracted to the resulting choices, and my inquisitive heart may waver toward paths other than that which is optimal. I cannot hold my own greed in check enough for me to tell you that will never happen. I acknowledge that. But I will gloss over nothing. I will speak openly and honestly. Even if the result of that will damage your trust, I will expend no effort to win that trust back. No matter what might happen, I will, without fail, bring you to the future you desire. I absolutely, absolutely will. So as the choices necessary for that become clear, would you not let me be the one to choose? It will be precisely according to the preamble for the pact: I will grant what you desire, what it is that you seek. It will be no more and no less than this. After that, how much you permit your body to be sliced for the sake of that which you desire and crave is up to you. I have conveyed my resolve. Next, I want to hear yours. I want you to demonstrate that you, who would form a pact with me, who would benefit from my cooperation, have the enduring spirit required to arrive at the future without fail. It is you, the first and only one to overcome the second Trial, who can puff out your chest and speak these words with pride. Do this, please me, and I shall release you from the tomb and guide you to the third Trial. Beyond that rests the liberation of the Sanctuary. In so doing, the precious people most important to you, the people you care about held captive in the Sanctuary, will be saved. For the sake of this, you will undergo a true Trial. For the sake of that, seize me, use me, do with me as you please as you let your greed rage, and we shall grasp the future together. This is everything I have to offer to aid you and find what you desire, what you seek. I intend to peel back everything honestly and earnestly. I will not allow the other girls around us to interfere any longer. It is as you said: This is a matter between you and I alone. I want you to give me your answer. I have told you everything… Truly the naked truth. Passionately. This might be close to love. A vow of love. So how will you respond to my love? I want a reply. This reply, after all, will be another thing serving to satisfy my curiosity." —With that, Echidna smiled adorably
Echidna is cute.
Time is the continued sequence of existence and events that occurs in an apparently irreversible succession from the past, through the present, into the future.[1][2][3] It is a component quantity of various measurements used to sequence events, to compare the duration of events or the intervals between them, and to quantify rates of change of quantities in material reality or in the conscious experience.[4][5][6][7] Time is often referred to as a fourth dimension, along with three spatial dimensions.[8]
Time has long been an important subject of study in religion, philosophy, and science, but defining it in a manner applicable to all fields without circularity has consistently eluded scholars.[7][9] Nevertheless, diverse fields such as business, industry, sports, the sciences, and the performing arts all incorporate some notion of time into their respective measuring systems.[10][11][12]
Time in physics is operationally defined as "what a clock reads".[6][13][14]
The physical nature of time is addressed by general relativity with respect to events in spacetime. Examples of events are the collision of two particles, the explosion of a supernova, or the arrival of a rocket ship. Every event can be assigned four numbers representing its time and position (the event's coordinates). However, the numerical values are different for different observers. In general relativity, the question of what time it is now only has meaning relative to a particular observer. Distance and time are intimately related, and the time required for light to travel a specific distance is the same for all observers, as first publicly demonstrated by Michelson and Morley. General relativity does not address the nature of time for extremely small intervals where quantum mechanics holds. At this time, there is no generally accepted theory of quantum general relativity.[15]
Time is one of the seven fundamental physical quantities in both the International System of Units (SI) and International System of Quantities. The SI base unit of time is the second. Time is used to define other quantities, such as velocity, so defining time in terms of such quantities would result in circularity of definition.[16] An operational definition of time, wherein one says that observing a certain number of repetitions of one or another standard cyclical event (such as the passage of a free-swinging pendulum) constitutes one standard unit such as the second, is highly useful in the conduct of both advanced experiments and everyday affairs of life. To describe observations of an event, a location (position in space) and time are typically noted.
The operational definition of time does not address what the fundamental nature of it is. It does not address why events can happen forward and backward in space, whereas events only happen in the forward progress of time. Investigations into the relationship between space and time led physicists to define the spacetime continuum. General relativity is the primary framework for understanding how spacetime works.[17] Through advances in both theoretical and experimental investigations of spacetime, it has been shown that time can be distorted and dilated, particularly at the edges of black holes.
Temporal measurement has occupied scientists and technologists and was a prime motivation in navigation and astronomy. Periodic events and periodic motion have long served as standards for units of time. Examples include the apparent motion of the sun across the sky, the phases of the moon, the swing of a pendulum, and the beat of a heart. Currently, the international unit of time, the second, is defined by measuring the electronic transition frequency of caesium atoms. Time is also of significant social importance, having economic value ("time is money") as well as personal value, due to an awareness of the limited time in each day and in human life spans.
There are many systems for determining what time it is, including the Global Positioning System, other satellite systems, Coordinated Universal Time and mean solar time. In general, the numbers obtained from different time systems differ from one another.
Generally speaking, methods of temporal measurement, or chronometry, take two distinct forms: the calendar, a mathematical tool for organising intervals of time,[18] and the clock, a physical mechanism that counts the passage of time. In day-to-day life, the clock is consulted for periods less than a day, whereas the calendar is consulted for periods longer than a day. Increasingly, personal electronic devices display both calendars and clocks simultaneously. The number (as on a clock dial or calendar) that marks the occurrence of a specified event as to hour or date is obtained by counting from a fiducial epoch – a central reference point.
History of the calendar
Main article: Calendar
Artifacts from the Paleolithic suggest that the moon was used to reckon time as early as 6,000 years ago.[19] Lunar calendars were among the first to appear, with years of either 12 or 13 lunar months (either 354 or 384 days). Without intercalation to add days or months to some years, seasons quickly drift in a calendar based solely on twelve lunar months. Lunisolar calendars have a thirteenth month added to some years to make up for the difference between a full year (now known to be about 365.24 days) and a year of just twelve lunar months. The numbers twelve and thirteen came to feature prominently in many cultures, at least partly due to this relationship of months to years. Other early forms of calendars originated in Mesoamerica, particularly in ancient Mayan civilization. These calendars were religiously and astronomically based, with 18 months in a year and 20 days in a month, plus five epagomenal days at the end of the year.[20]
The reforms of Julius Caesar in 45 BC put the Roman world on a solar calendar. This Julian calendar was faulty in that its intercalation still allowed the astronomical solstices and equinoxes to advance against it by about 11 minutes per year. Pope Gregory XIII introduced a correction in 1582; the Gregorian calendar was only slowly adopted by different nations over a period of centuries, but it is now by far the most commonly used calendar around the world.
During the French Revolution, a new clock and calendar were invented in an attempt to de-Christianize time and create a more rational system in order to replace the Gregorian calendar. The French Republican Calendar's days consisted of ten hours of a hundred minutes of a hundred seconds, which marked a deviation from the base 12 (duodecimal) system used in many other devices by many cultures. The system was abolished in 1806.[21]
time standard is a specification for measuring time: assigning a number or calendar date to an instant (point in time), quantifying the duration of a time interval, and establishing a chronology (ordering of events). In modern times, several time specifications have been officially recognized as standards, where formerly they were matters of custom and practice. The invention in 1955 of the caesium atomic clock has led to the replacement of older and purely astronomical time standards such as sidereal time and ephemeris time, for most practical purposes, by newer time standards based wholly or partly on atomic time using the SI second.
International Atomic Time (TAI) is the primary international time standard from which other time standards are calculated. Universal Time (UT1) is mean solar time at 0° longitude, computed from astronomical observations. It varies from TAI because of the irregularities in Earth's rotation. Coordinated Universal Time (UTC) is an atomic time scale designed to approximate Universal Time. UTC differs from TAI by an integral number of seconds. UTC is kept within 0.9 second of UT1 by the introduction of one-second steps to UTC, the "leap second". The Global Positioning System broadcasts a very precise time signal based on UTC time.
The surface of the Earth is split up into a number of time zones. Standard time or civil time in a time zone deviates a fixed, round amount, usually a whole number of hours, from some form of Universal Time, usually UTC. Most time zones are exactly one hour apart, and by convention compute their local time as an offset from UTC. For example, time zones at sea are based on UTC. In many locations (but not at sea) these offsets vary twice yearly due to daylight saving time transitions.
Some other time standards are used mainly for scientific work. Terrestrial Time is a theoretical ideal scale realized by TAI. Geocentric Coordinate Time and Barycentric Coordinate Time are scales defined as coordinate times in the context of the general theory of relativity. Barycentric Dynamical Time is an older relativistic scale that is still in use.
Two contrasting viewpoints on time divide prominent philosophers. One view is that time is part of the fundamental structure of the universe – a dimension independent of events, in which events occur in sequence. Isaac Newton subscribed to this realist view, and hence it is sometimes referred to as Newtonian time.[43][44] The opposing view is that time does not refer to any kind of "container" that events and objects "move through", nor to any entity that "flows", but that it is instead part of a fundamental intellectual structure (together with space and number) within which humans sequence and compare events. This second view, in the tradition of Gottfried Leibniz[13] and Immanuel Kant,[45][46] holds that time is neither an event nor a thing, and thus is not itself measurable nor can it be travelled.
Furthermore, it may be that there is a subjective component to time, but whether or not time itself is "felt", as a sensation, or is a judgment, is a matter of debate.[2][6][7][47][48]
In Philosophy, time was questioned throughout the centuries; what time is and if it is real or not. Ancient Greek philosophers asked if time was linear or cyclical and if time was endless or finite.[49] These philosophers had different ways of explaining time; for instance, ancient Indian philosophers had something called the Wheel of Time. It is believed that there was repeating ages over the lifespan of the universe.[50] This led to beliefs like cycles of rebirth and reincarnation.[50] The Greek philosophers believe that the universe was infinite, and was an illusion to humans.[50] Plato believed that time was made by the Creator at the same instant as the heavens.[50] He also says that time is a period of motion of the heavenly bodies.[50] Aristotle believed that time correlated to movement, that time did not exist on its own but was relative to motion of objects.[50] he also believed that time was related to the motion of celestial bodies; the reason that humans can tell time was because of orbital periods and therefore there was a duration on time.[51]
The Vedas, the earliest texts on Indian philosophy and Hindu philosophy dating back to the late 2nd millennium BC, describe ancient Hindu cosmology, in which the universe goes through repeated cycles of creation, destruction and rebirth, with each cycle lasting 4,320 million years.[52]Ancient Greek philosophers, including Parmenides and Heraclitus, wrote essays on the nature of time.[53]Plato, in the Timaeus, identified time with the period of motion of the heavenly bodies. Aristotle, in Book IV of his Physica defined time as 'number of movement in respect of the before and after'.[54]
In Book 11 of his Confessions, St. Augustine of Hippo ruminates on the nature of time, asking, "What then is time? If no one asks me, I know: if I wish to explain it to one that asketh, I know not." He begins to define time by what it is not rather than what it is,[55] an approach similar to that taken in other negative definitions. However, Augustine ends up calling time a "distention" of the mind (Confessions 11.26) by which we simultaneously grasp the past in memory, the present by attention, and the future by expectation.
Isaac Newton believed in absolute space and absolute time; Leibniz believed that time and space are relational.[56] The differences between Leibniz's and Newton's interpretations came to a head in the famous Leibniz–Clarke correspondence.
Philosophers in the 17th and 18th century questioned if time was real and absolute, or if it was an intellectual concept that humans use to understand and sequence events.[49] These questions lead to realism vs anti-realism; the realists believed that time is a fundamental part of the universe, and be perceived by events happening in a sequence, in a dimension.[57] Isaac Newton said that we are merely occupying time, he also says that humans can only understand relative time.[57] Relative time is a measurement of objects in motion.[57] The anti-realists believed that time is merely a convenient intellectual concept for humans to understand events.[57] This means that time was useless unless there were objects that it could interact with, this was called relational time.[57] René Descartes, John Locke, and David Hume said that one's mind needs to acknowledge time, in order to understand what time is.[51] Immanuel Kant believed that we can not know what something is unless we experience it first hand.[58]
Time is not an empirical concept. For neither co-existence nor succession would be perceived by us, if the representation of time did not exist as a foundation a priori. Without this presupposition, we could not represent to ourselves that things exist together at one and the same time, or at different times, that is, contemporaneously, or in succession.
Immanuel Kant, Critique of Pure Reason (1781), trans. Vasilis Politis (London: Dent., 1991), p.54.
Immanuel Kant, in the Critique of Pure Reason, described time as an a priori intuition that allows us (together with the other a priori intuition, space) to comprehend sense experience.[59] With Kant, neither space nor time are conceived as substances, but rather both are elements of a systematic mental framework that necessarily structures the experiences of any rational agent, or observing subject. Kant thought of time as a fundamental part of an abstract conceptual framework, together with space and number, within which we sequence events, quantify their duration, and compare the motions of objects. In this view, time does not refer to any kind of entity that "flows," that objects "move through," or that is a "container" for events. Spatial measurements are used to quantify the extent of and distances between objects, and temporal measurements are used to quantify the durations of and between events. Time was designated by Kant as the purest possible schema of a pure concept or category.
Henri Bergson believed that time was neither a real homogeneous medium nor a mental construct, but possesses what he referred to as Duration. Duration, in Bergson's view, was creativity and memory as an essential component of reality.[60]
According to Martin Heidegger we do not exist inside time, we are time. Hence, the relationship to the past is a present awareness of having been, which allows the past to exist in the present. The relationship to the future is the state of anticipating a potential possibility, task, or engagement. It is related to the human propensity for caring and being concerned, which causes "being ahead of oneself" when thinking of a pending occurrence. Therefore, this concern for a potential occurrence also allows the future to exist in the present. The present becomes an experience, which is qualitative instead of quantitative. Heidegger seems to think this is the way that a linear relationship with time, or temporal existence, is broken or transcended.[61] We are not stuck in sequential time. We are able to remember the past and project into the future – we have a kind of random access to our representation of temporal existence; we can, in our thoughts, step out of (ecstasis) sequential time.[62]
Modern era philosophers asked: is time real or unreal, is time happening all at once or a duration, If time tensed or tenseless, and is there a future to be?[49] There is a theory called the tenseless or B-theory; this theory says that any tensed terminology can be replaced with tenseless terminology.[63] For example, "we will win the game" can be replaced with "we do win the game", taking out the future tense. On the other hand, there is a theory called the tense or A-theory; this theory says that our language has tense verbs for a reason and that the future can not be determined.[63] There is also something called imaginary time, this was from Stephen Hawking, he says that space and imaginary time are finite but have no boundaries.[63] Imaginary time is not real or unreal, it is something that is hard to visualize.[63] Philosophers can agree that physical time exists outside of the human mind and is objective, and psychological time is mind-dependent and subjective.
well that's all.
