What is the story of The Butterfly Effect ?

Ivan retrieves his memories through a notepad, which makes him aware of his mistakes and the loss of several of his best friends. Especially Carly, the girl he had a crush on as a child. As his childhood memories slowly recovered, Ivan slowly remembered many things from his childhood, and it was then that he was surprised to realize that he had done so many things wrong.

Instead of feeling happy when he regained his memories, guilt began to torment him instead of a black hole, making him extremely painful. On the verge of pain, Ivan hopes to be able to completely get rid of the shadow of his childhood, so he fantasizes about using his consciousness to dive into his childhood body to redeem those things he did wrong, and cherish his friendship with childhood friends, and love everyone well. Clearly, Ivan wants to change his past.

But everything Ivan has changed in the past, when he returns to the present, finds that they have brought unexpected results, and the damage is even worse, and things are getting worse and worse. In order to make up for his mistake, Ivan returns to the past to try to erase the traces, but it backfires, and what he does can only lead to the gradual collapse of the real world again. So over and over again, he rushes between the increasingly chaotic past and the present, until it comes to an irreversible end.

Ivan's dream of trying to change the past and live happily with his crush on Kaile has also come to naught.

The movie tells the story of Ivan (played by Ashton Couch) who experienced a series of bad things as a child, which damaged his otherwise perfect life. Tormented by terrible memories of his childhood, Ivan enlists the help of a psychiatrist, who encourages him to write down what happened in detail, but things get worse and worse.

The in-depth analysis of the movie "Butterfly Effect" is as follows:

The beginning of the film has actually laid a foreshadowing for the audience, "It is said that some small things as small as a butterfly flapping its wings can cause a storm that sweeps across the earth." —Chaos Theory. This sentence is the key to understanding the plot of the whole movie.

The movie uses flashbacks, and at the beginning the protagonist is hunted down, and a meaningful sentence is written, and the suspense begins. The first half hour of the movie, around Evan's growth process, is still in normal time and space. In this process, there are two time nodes, one is 6 years later and the other is 7 years later.

During this time, Evan lost a total of 6 things that lost his memory, and these amnesiac spaces provided a fulcrum for the later protagonist to travel through time and space.

The director arranged a total of four endings, but only two endings were actually used. One is the end of the director's extended version, the family movie that Evan saw was that Evan's mother was about to give birth to Evan, and Evan, who entered history, decided to end it all by himself, he grabbed the umbilical cord with both hands and ended the life he was about to start, there was no Evan in real life, Kelly and Tommy were taken under the guardianship of a mother after the divorce, far away from the BT father, and naturally there was no detonator incident.

The theatrical version ends with the family movie Evan sees at a party where he first meets Kelly, and Evan scolds Kelly for not being good friends with Kelly, and Kelly and Tommy's custody is also given to her mother. After work, Evan meets Kelly on the street, but he doesn't recognize him. The other two endings are also set according to the ending of the theatrical version, one is that after Evan meets Kelly, he turns back to chase Kelly, and the other is that the two recognize each other.

Significance of the film:

This movie has one of the most brilliant ideas. And the most brilliant idea of this idea is that it provides an opportunity to regret again and again, a variety of possibilities for life, a dream to go back to the past and change your fate.

Based on the madness of a perfectionist, the protagonist Ivan builds his rightful memories on those rallying points with vague memories.

And after these memories are built, his subsequent memories will all be rewritten due to the butterfly effect, so his life will be constantly rewritten. No one's life is completely beautiful and without flaws, so when we recognize the existing flaws, the world will become a better place instead of constantly hoping for better and more vain things.

The butterfly effect refers to a chaotic phenomenon in a dynamic system where small changes in the initial conditions can lead to a long-term huge chain reaction of the whole system. It means that something that seems unrelated or very small on the surface can make a huge difference. The most common explanation for this effect is that "a butterfly flapping its wings in Brazil can cause a tornado in Texas a month later."

The specific origin of the butterfly effect is that in the winter of 1961, the American atmospheric physicist Edward Lorenz used a computer program to calculate a mathematical model that simulated the flow of air in the atmosphere.

After inspection, it was found that the problem was in the data, the accuracy of the data printed on the second time was only 3 decimal places, but the correct accuracy of the data should be 6 decimal places. Lorenz was so shocked that in 1963 he published "Decisive Non-Cyclical Flows", in which he analyzed this effect. This article was later widely quoted.

To illustrate this theory more vividly, he also wrote in another article: "A meteorologist mentions that if this theory proves correct, a seagull flapping its wings is enough to change the weather forever". However, in the later **, he used a more poetic butterfly, which is the origin of the famous "butterfly effect".

The most common description of this effect is that a butterfly in the Amazon rainforest of South America, with a few occasional flaps of its wings, can cause a tornado in Texas, USA, two weeks later. That is, over a long period of time and over a large scale, small changes in the air system can lead to a chain reaction and ultimately to large changes in other systems.

The Butterfly Effect movie tells the story of Ivan (Ashton Couch) who experienced a series of bad things as a child, which damaged his otherwise perfect life. Tormented by terrible memories of his childhood, Ivan asked a psychiatrist.

With his help, the doctor encouraged him to write down everything that had happened, but things got worse and worse.

Tormented by terrible memories of his childhood, Ivan enlists the help of a psychiatrist, who encourages him to relax himself by traveling and, in addition, to write down in detail what happened every day. Now, with the help of travel and journaling, Ivan, who entered college, suddenly realized that a notebook that kept track of what he did every day could help him regain his childhood memories.
