Interestingly, some people think "Source Code" is brain-burning, but they can still understand it somewhat.
Some people also think that "Source Code" is actually very simple, but there are some parts that they don't understand.
So with the release of the movie, many various interpretations and analytical film reviews began to appear on the Internet.
"Some people say that "Source Code" is too brain-burning, but in fact, the plot of "Source Code" is very simple! Just like "A Dream of Red Mansions" requires understanding the first five chapters, "Source Code" only needs to understand chapters 33 to 35
In just 2 minutes, you can understand this movie!
In these 2 minutes, the professor explained the origin of the source code by explaining two characteristics of the brain. The two characteristics of the brain he interpreted are: 1. The consciousness will not disappear immediately after death; 2. The consciousness will remain before the death of the brain.
The next 8 minutes are indelible and profound memories (afterimages).
In short, after death, there will be 8 minutes of memory in the brain that will not disappear immediately. It can be extracted, superimposed, and reconstructed into the last 8 minutes of the deceased's life. After the picture is digitized, it forms what the professor calls the "source."
"Code", the so-called digitization here may also be understood as the digitization of biological information.
Knowing this, it's not hard to understand this super simple story:
Lin Yunbin is a soldier. He "died" while returning in a helicopter from a mission two months ago and became a vegetative state. Note that this is a vegetative state. This is very important! He was kept alive in the laboratory by the professor through legal means.
, waiting to accept tasks in order to carry out source code planning.
The lame professor waited for 2 months, and finally a terrorist incident occurred. A train was attacked by a terrorist, and no one on board survived. The terrorists also posted news online that they would continue to carry out a series of terrorist activities in the city center.
In order to find the murderer, the professor immediately rushed to the scene to collect the brain afterimages of all the deceased, superimposed the brain information of each person's first 8 minutes of life, and digitally reconstructed a source code that lasted only 8 minutes through biological information. Of course, we may wonder,
This acquisition and reconstruction process is a bit unbelievably fast, but that is not the point. The point is that this source code shows a virtual world that lasts for 8 minutes. Then the professor found one of them that matched his physical signs of the vegetative Lin Yunbin.
The deceased Li Zheng, as the source code entrance, deleted the original memory belonging to Li Zheng and implanted Lin Yunbin's consciousness code so that he could enter the source code to seek the truth. Note that the original Li Zheng's memory has been rewritten or deleted here!
Because it is just a piece of biological source code, the professor believes that everything Lin Yunbin’s consciousness did in the source code was just to reassign this period of time in the source code!
Including implanting Lin Yunbin's consciousness is also a reassignment. It will not change the established facts of the real world, but it will help to find the real culprit through constant assignment and reorganization of the source code!
In fact, to put it simply, it is equivalent to "cracking the password" of a computer. Lin Yunbin's different choices and decisions during the operation of the code are a kind of reassignment and calculation to produce different results.
But the professor himself didn't know that he had inadvertently opened the door to a new world.
Chen Juan was rescued and watched helplessly as she was hit and died, so she must continue to live; Chen Juan was shot to death and would not be reported to have died in a train explosion; she almost got through when she called the professor in the source code
...
Various signs made Lin Yunbin, who kept traveling (reassigning values), slowly realize: 8 minutes later, although the source code has completed running, the world related to the 8 minutes of running is still continuing, and it is different from the real world! This is re-creation
Several different new worlds! If you change the fatal ending of one of the worlds, you may be able to continue to survive in this world.
So he strongly asked the female captain to give him another chance and terminate his life in the real world after it was over. Maybe he was afraid that his consciousness would be pulled back to the real world.
The following is easy to understand. Lin Yunbin's consciousness changed Li Zheng's destiny in the newly created world, and his consciousness continued in him. At this time, there was no train explosion in the new world, so the vegetative Lin Yunbin was still lying in the experiment.
Waiting for the mission in the room, the female captain also received an inexplicable text message.
In the text message, Xin Li Zheng hinted to the vegetative person through the female captain that one day, the consciousness of the vegetative Lin Yunbin will change his destiny in the creation of a new world and survive in another form in this world.
Too simple sometimes just can't explain things clearly, so I will try to use slightly more complicated language to explain clearly:
What exactly is source code and how it is formed is particularly interesting and crucial to understanding the film. The doctor pointed out that the formation of source code is based on two characteristics of the brain:
The first characteristic is that the brain waves will not be cut off immediately after death. In other words, for a period of time after death, all the information and various memories in the brain will be the same as before death. When advanced technology is used in a timely manner to maintain power, it can be
Brain information is extracted and perpetuated.
If you continue to delve deeper, you can easily come to the conclusion that the world of the source code is not constructed by one person's brain information, but by the intersection and superposition of the brain information of all the deceased people on the train. This world may not be as complete as the real world.
But it is very realistic. This explains why the source code world is so colorful, can recall the memory of the deceased long ago, and can be connected to the world outside the train.
The second characteristic is that the brain waves will gradually strengthen the 8 minutes before death into a deep memory (afterimage) before the power is turned off. Compared with the various brain information in the first characteristic, this memory is clearer and more substantial, enough for the professor to
Everyone's 8 minutes are superimposed into a very clear virtual world, and Li Zheng's memory can be easily found and erased in it.
It must be noted here that Li Zheng’s 8-minute memory must have been erased, because Chen Juan knew him, but he did not know Chen Juan. However, as one of the sources of information that builds the entire source code world, Li Zheng’s 8-minute memory was definitely erased.
Because all the brain information is not as deep as the 8-minute memory, it is not so easy to search and clear. Therefore, every time Lin Yunbin looks in the mirror, he can clearly image Li Zheng's appearance. You must know that Li Zheng is very interested in Lin Yunbin.
I've never met him before.
Why should Li Zheng's memory afterimages be cleared? In fact, it is to allow Captain Lin's brain waves to have a relatively matching carrier to operate. He is not really dead, he actually became a vegetative state, but his brain is not dead, but he is
Before he suspended his own death, he also formed a strong pre-death memory, and no memory was formed in the next 2 months. This pre-death memory was also erased by the professor, so he only remembered that he was in the cabin before his death, but did not remember
He was hit, and his memory was not restored until someone mentioned it - simply speaking, it is equivalent to hard drive data recovery.
The new world generated by the source code can last indefinitely. This great discovery was slowly realized by Captain Lin during many time travels.
The professor probably didn't know that he had inadvertently opened the door to rebuilding a new world. Of course, this is my personal opinion. I am not too inclined to think that he knew the inside story and deliberately concealed the truth.
When Captain Lin traveled through time for the second time, he began to discover that "it was the same train, but it was a little different." The professor's original intention was to let him use it as little as possible to affect other people's affairs. If necessary, he could even shoot everyone in turn.
This "low-key" method of testing who is the murderer is used to find out the real murderer. However, Captain Lin is relatively high-profile. He "stupidly" interferes with almost everyone's memory and radically reassigns the source code. He gradually
It was found that the calculation results or some people's memories had corresponding changes.
The most serious one was the third time he traveled through time. He followed a passenger to get off the bus with his girl. Since this passenger was not dead, it stands to reason that he would not be included in the source code construction information source, and his behavior after getting off the bus should also be unintentional.
It can be known, but because he reassigned (tracked) this source code and used it as a brand new memory to record everything he saw, filling in the blanks of the passengers' behavior.
What's more interesting is that when he was fighting with the passengers, the train exploded. He did not die in the eighth minute, but Chen Juan's fate was also changed at the same time.
If he hadn't been accidentally hit by a train, he wouldn't have even died and returned to the real world.
All this (and more signs later) made him realize very clearly that he could not exist outside Li Zheng's 8-minute memory as the professor said. The professor's premise was that Li Zheng
If he dies, what if he doesn’t die? He believes that as long as he doesn’t die, his brainwaves will always remain in Li Zheng’s body.
The formation of this concept was relatively clear when he returned for the fifth time, and it was already quite clear when he begged the female captain to give him one last chance. Terminating the life of Captain Lin in the real world is not to prevent the brain waves from returning automatically, but to prevent
The professor manually pulled it back manually.
Finally, strictly speaking, the term parallel world is inappropriate.
It should be said that every time you teleport, a brand new bifurcated world opens.
Why do you say that? Assuming that the first time you traveled through time was at 3:00 p.m. on the day of the incident, the second world you traveled to was at 7:40 a.m. (the explosion occurred at 48:00), 3:00 and 7:40 a.m., obviously
The two worlds are not parallel in time.
Then continue, assuming that the second teleportation is launched immediately after the first teleportation, then the time should be 3:08, but the third world teleported to is still 7:40 in the morning, which is obviously not parallel to the first world.
It's not even parallel to the time and events of the second world.
By analogy, every time he travels through, the new world he opens starts at 7:40, which is absolutely not parallel to the first world. They are not completely parallel to each other. It can only be said that they start at different time points in the first world.
The new forked worlds, as he said at the end, are all different forked paths in life caused by different choices.
So the bifurcated world is actually a brand new world created when people make different choices at a certain moment. This world clones the world information before this point in time, and then develops freely according to people's choices. But usually everyone only has one
The right to choose, and he unexpectedly got multiple opportunities to choose, and in the end he made the right choice. At the end of the film, he said that the professors actually created a new world, which is what he meant - not a parallel world with the existing one.
Open a channel or something or change history or something.
In fact, this movie is quite interesting in terms of technical terms. What is the source code? Computer applications are actually a bunch of binary codes. This binary code is actually a kind of machine language that can be recognized by the CPU. Application
When a program is running, the system loads the binary code of the program into memory and then gives it to the CPU to recognize and execute. These binary codes are the source code.
A process is a running application.
A thread is a single sequence of control flow in a process. A thread is created in a process and performs a certain task. After the task is completed, the thread terminates.
Threads are subordinate to processes, and a process can contain N threads at the same time. These N threads run simultaneously in time until they terminate after their respective tasks are completed. It can be understood as N cars on the highway, driving forward at the same time.
There are different destinations and they will stop after reaching their destinations.
If you interpret it from this point of view, you will find that it is actually very vivid.
First of all, the entire world is a running application and a process. We all run in this process.
This chapter is not over, please click on the next page to continue reading! The basis is based on a setting, that is, humans will retain the last 8 minutes of memory when they die. The professors in the movie believe that these 8 minutes of memory are
A piece of source code from the application "World".
After the train bombing, the professor saved the memory (source code) of a passenger on the train 8 minutes before his death. His idea was to start a thread to repeatedly execute these 8 minutes of code to find the terrorists to avoid
The second explosion is about to occur in the city center. But they have not mastered the ability to create threads and can only use existing threads. Captain Lin died, leaving only his brain active, and this active brain is a thread.
Captain Lin's brain (thread) is repeatedly started, allowing the thread to execute the 8 minutes of source code. Theoretically, after the execution of the 8 minutes of source code is completed, the thread will terminate. Captain Lin's brain will
Break away and return to the initial state. In the movie, Captain Lin is shown in a completely enclosed iron box to represent this state.
The professor's theory seems to have been verified during actual operation, because Captain Lin did return to the initial state after 8 minutes of each task execution.
However, the professor was wrong. The reason why Captain Lin came back after 8 minutes of executing the mission was not because the source code of those 8 minutes had been executed, but because Captain Lin died every time, either by being blown up or
He was hit by a train or shot dead by terrorists. The two times he was hit by a train and killed, Captain Lin came back only after the train exploded, which lasted more than 8 minutes. Therefore, the thread did not terminate when the source code was executed, but
It ends with the termination command (the death of Captain Lin).
So at the end of the movie, there are two worlds (processes) running in parallel, one is the original world, and the other is the cloned new world.
In the original world, a train explosion occurred. In the cloned new world, a train explosion did not occur."
