Buddha said: flowers and the world, as to leaf
Film, this is not much to say. The hot glare screen can not be said, but also smooth and lively, the story is not thrilling, but also the ups and downs. If not to study the inside, they can see it as a suitable cinema about the 35 friends, chewing popcorn while watching a standard commercial film. Its real worth exploring, is the director in order to establish their concept of story structure, if the depth of which is there is a different world.
Deterministic (mechanistic):
The core concept of the film is the story of parallel universes, but when it comes to this concept, we must first answer the question is: What is random? Give a simple example, dice generally considered to be a random phenomenon. Because it is the result of unpredictable, so people rely on gambling to stroke his luck. But the depth test may not be found after a random event. The results obtained with the dice landing their initial conditions and environmental factors strictly related, if the cast can accurately control the starting place, angle, direction, air flow, temperature and all other factors, so every time the results will be exactly the same cast. Dice that this seemingly random process is actually likely to be a defined process.
Touzi the case, then of course the same coin, computer-generated random number is obtained by an algorithm that pseudo-random number (usually associated with the timer), if as we go deeper, you will be surprised to find out everything you can think of pseudo-random phenomena may all be random. Each result is caused by the results of its causes, and its cause and reason for the results of its own. Flowers are destined to open, because that brings nectar gust, the wind is destined to come, because the distant wings of the butterfly pat (Chaos), is destined to take the butterfly wings, because the other woman with butterfly Masamitsu body chosen to dance.
So it seems everything is doomed, because the past determines the present results, as those who consider themselves able to break free of the higher, with freedom? In the determinist view, this is self-deception.
Free will:
Philosophically, people can have all the freedom is the freedom of choice, that is, the so-called free will. When the Murphys to spread out his hands when Mourinho, Mourinho began the exercise of this freedom, but no matter what he was eating pills, his choice has already doomed. After thinking people will consider all factors and make decisions, and dedication that this is their own decision. But consider carefully, if people in a Rolls-Royce and a lucky choice between the 100 individuals in 99 would choose the former, while the rest of that you want to prove with his own free choice, but this He did not only prove itself first by the idea of ​​freedom of decision (and this idea is because you want to refute the determinism of this impulse comes, this impulse has its own reasons) to just the reverse selection proof of determinism, but also the loss of a Rolls Royce. Like "Pirates of the dream space" said: When you try not to think about elephants when your first thought is the elephant.
Some people might think, if faced with two almost identical Rolls-Royce, the only difference is the chassis on a letter, and the choice of those who can not see the letter, then select the person's choice not to other factors not dominate the impact of the events developed it? However, if carefully considered, because selection may favor the right direction and easily choose the right one, and he's such a preference may be caused by childhood trauma of some kind of belief fixation. In this way we can still say that people do not exist free will, everything has been decided, but we can not understand.
The face of such a pessimistic conclusion, most people can not calm. We really do not do anything for yourself? I'm hungry so I ate bread, I'm cold, so I wear a dress, I grew up sex drive, so I found a wife, I read a chapter of this travel log or a journal of the Aegean Sea beautiful scenery, so give birth to a dream around the world. We just pushed by life, follow the crowd. We play the role of writer, but someone else, he just gently pushed the first domino, they created a big world. Who is he? Some say God, some people say is Allah, but this is another problem.
Quantum Theory:
In the 18th and 19th centuries, based on causal loop Laplace's decision on the doctrine established by the rule of the whole intellectual. Including many from Newton to Einstein, we are all his followers. However, a scientific revolution has brought the philosophy of non-determinism dawn. The establishment of quantum mechanics at the micro level, macro-question of causality, which was raised in a so-called "superposition" of microscopic particles of the state is uncertain, so the concept of random back again before our eyes.
As an example, we usually think outside of the nucleus with electrons orbiting around, but according to quantum mechanics, the electronics are not the same as the Earth around the sun circling around the nucleus, it may appear in any position around the nucleus of one or This is an electron may also appear in his place. It is only through observation, we can determine their status, but it is pain is observed and the egg changes its state. E in the end it before the observation in what state? The eggs of this pain can be a metaphor to explain: you come to our house, I was not at home then? When you open the door when you can be sure I was not, but before the door, I was in what state? I have more spare time, could at home, may be in the school, may be on the road. I may be in the same position in all of superposition, until you open the door looked at, so I determine the location of the.
Schrodinger's cat:
Do not say you can not figure out such things, many physicists and philosophers have scratched his head, so in addition to the Schrodinger laugh out a thought experiment: will a cat locked up in the box, the box is also equipped with a small piece of uranium, a glass bottle filled with gas, and a set by the detector controlled by the executive body consisting of a hammer. Uranium is an element of instability, the decay is triggered when the release-ray detector, driven hammer smashed the glass, the release of gas will poison the cat. Uranium does not decay before the gas is not released, the cat is alive. When uranium atoms decay is uncertain, so it is in the superposition state. Schrodinger dig said: Open the box is not observed before, according to the interpretation of quantum mechanics, the cat box in a "dead - live superposition" - Jisi another alive, to wait for someone to open the box to see a cat's life and death decisions . Quantum mechanics terms, the moment you open the box, because you looked at the collapse of the wave function. This is simply incredible, the macro-micro-chaos into the absurd - the cat is either dead or alive, the two must be one, can not simultaneously Jisi they live. No wonder the Schrödinger cat paradox hear Hawking said: "I went to a gun killed the cat!"
Parallel universe:
It only hurt for the cat eggs and wave function collapse, a reasonable explanation is that the universe is now divided. At this moment, all possibilities occur simultaneously in a parallel universe split among a number of cats in the universe is dead, but alive in some other universe. This interpretation is a major blow to determinism, the assumption that not only affect the micro-micro-uncertainty, this uncertainty superposition of the incident, let us into the many possible moment, a universe, no wonder the Buddha said: one one of the world.
In the "source code", the protagonist Colter is by Dr. Rutledge invented a device with Fentress residual brain waves quantum force field (the movie scenario) back to Fentress woke up again and again opened his eyes the moment the superposition state and enter on the possible number of parallel universe in one. This is why every time he opened his eyes, happened roughly the same but are different. Christina first told him that she woke up canceled XX (after the story is conjectured that by law courses), and then hung up the phone and did not help Colter shoe on the Coke. The second time she woke up when Christina told Colter legal Ke registered and ready to go to India, there is no phone rings, and help him clean the shoes of Coke. There are many other details of the film will not list them.
Division of the universe constantly and bring to a phylogenetic tree showing the model, all the universe can be traced back to a single initial point, but the development of the universe, separated from each other and no longer allows the contact. This also explains why Colter for the first time on the train called Dr. Rutledge later, Rutledge can not be received his phone messages, because after a Rutlegde not by Colter back that the universe evolved. Colter and later when she sent a message to Goodwin received his information, because this time she is in the universe at Colter sent messages after the incident node.
From the evolutionary tree model of parallel universe that we can know that the film can only be saved by the Colter is one of many in a parallel universe (this one will end in to save this event split into a number). But we can imagine, by the placement of bombs from the other universe of events may also have (or may not) such a Colter in the implementation of such a task. However, the model tree has a problem: all of the Colter are returned to the same point in time the superposition state (traceable, and this source only), but Colter also have a memory of the future, so when they return to overlay This time when the state will have a variety of Colter's memory and possible future conflict with the universe. Or in another words, many from the possible future of the universe Colter with their own memories into the open my eyes the moment Colter, he not only has more than one soul at the moment (assuming the soul of this form), and these ghosts from the same individuals. This logic, the film can not answer, because its vision of the return mechanism itself does not exist, but it raises another question.
Ontology:
Who am I, what is there, in the end what I decided I was, on a second that I went to the next second or me? This issue is raised in the film where Colter see in the mirror is another vice appearance (Fentress look) the moment, and Colter that everything around is a virtual image.
This problem can be considered starting from a pepper. If I was in Shanghai, I think this may be particularly spicy chili, but I was in Chongqing, I probably think it was not spicy. So in the end he is not hot enough it spicy? It depends on my taste buds to the brain pass signals. The same token, I could see Fengyun red pepper, but a red-green blindness may say it is green. I can find a bunch of people to help me prove I was right, but if people are red-green blindness around the world do? So it seems the situation has become recognized Fengyun color is green pepper, and I is the red-green blindness. So we go deeper, we can even directly questioned the existence of pepper. I now confirm its existence but because I can see it, touch it, taste it, and so on. But in the final analysis these are just a bunch of sensory signals can be assumed that the use of computer simulation of all these signals to pass to the brain, a chili that does not exist then living in my concept of being.
So presumably we seem to never be able to determine the authenticity of the immediate scene, and confirmed our sense of the material world (for materialists) can only be the only source of Russell described as "instinctive faith." According to Ao Kanmu razor principle, it is not necessary a hypothetical complex built by the spiritual world.
String theory:
So, in the end what is the fundamental material in nature? To answer this question, theory, string theory is the best candidate. Big bang for the students read the word, are not unfamiliar, we thank IQ up to 180 students is in the ear scratching his head to study the theory. The theoretical assumptions, the basic unit of the universe is a one-dimensional strings, and countless one-dimensional string of shock or the formation of the closed circle of these strings resonate with each other, forming three thousand world, flowers and trees are all produced as resonance. A metaphor can be more image description. Compared to the one-dimensional string is the string, the strings when struck, its vibration of the music, and through the air resonance is we hear. Music is like. It is not the strings themselves, more than air, but we indeed heard it. As we see flowers and trees, its non-string itself, but it is generated as strings, it seems there is still no. No wonder the Buddha said: sex is zero, Kongjishise. Again, he said: There is no Bodhi tree, nor stand mirror, had not, where can the dust alight.
