Is Butterfly Effect 2 really done, and what is Butterfly Effect 2 about?

The butterfly effect refers to a dynamical system.

A small change in the initial conditions can have a huge long-term ripple effect on the entire system.

The butterfly effect is a chaotic phenomenon.

It shows that there are fixed numbers and variables in the development of any thing, and the development trajectory of things in the process of development has laws to follow, and there are also unpredictable "variables", which are often counterproductive, and a small change can affect the development of things, which proves that the development of things is complex.

American meteorologist Edward Lorenz.

This effect was analysed in 1963 in a submission to the New York Academy of Sciences. One meteorologist mentioned that if this theory proves correct, a seagull flapping its wings would be enough to change the weather forever. In later speeches and **, he used a more poetic butterfly.

The most common description of this effect is: "A South American Amazon."

Watershed rainforest.

The butterflies, occasionally flapping their wings, can cause a stir in Texas after two weeks.

A tornado.

The reason for this is that the movement of the butterfly's wings causes changes in the air system around it, and produces a weak air flow, and the generation of weak air flow will cause corresponding changes in the surrounding air or other systems, which causes a chain reaction, and eventually leads to great changes in other systems. He called it chaosology. Of course, the "butterfly effect" is primarily a metaphor for chaos.

It is also a true reaction to the butterfly effect. An inconspicuous small action can elicit a series of huge reactions.

Lorenz found that since errors grow exponentially, in this case, a small error has huge consequences over time. Later, Lorenz raised the issue in a speech. He believes that in the process of atmospheric motion, even if the various errors and uncertainties are small, it is possible to accumulate the results in the process, and after gradual amplification, form a huge atmospheric motion.

Therefore, it is impossible to have accurate weather for a long time.

Thus, Lorenz decided that he had discovered a new phenomenon: the result of the development of things, which is extremely sensitive to the initial conditions. He then identified this as "extreme instability to initial values", i.e., "chaos", also known as the "butterfly effect".

The film tells the story of Nick and his friends celebrating his girlfriend Julie's birthday in the suburbs, but on the way back, Julie was in a car accident, and Julie was unfortunately seriously injured and died, and Nick was very sad. Soon a year passed, and one day Nick found himself returning to the story of the past by watching the old **.

The Butterfly Effect 2 tells the story: Nick (Eric Lively) celebrates his girlfriend Julie (Erica Durance) in the suburbs with his friends, but on the way back, Julie was seriously injured and died, and Nick was very sad.

Soon a year passed, and one day Nick found himself able to go back in time by looking at the old **. In this way, he uses his superpowers to rewrite history and save Julie from disaster.

Although Nick is very excited about the resurrection of his girlfriend, the troubles of life still follow. Because of his previous experience, Nick keeps changing history in the hope that life can develop according to his own thinking. But the results often backfire, and there are always bigger problems.

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.

The butterfly effect is real, and in a sense, small changes in the scale can change the weather forever, but it is debatable whether butterflies can make any meaningful changes to the weather. ”

The butterfly effect was proposed by Edward Lorenz in the context of atmospheric desirability, and in fact, he proposed in his research that the wings of seagulls, rather than those of butterflies, can have enormous, unforeseeable consequences, and the butterfly effect was proposed by Dr. Phil Merriles, a term that Lorenz quoted in his conversation and titled in a research report published in 1969.

The butterfly effect is real, in the sense that small changes can change the weather forever, but it is debatable whether butterflies can make any meaningful changes to the weather, the butterfly effect can more or less capture people's imaginations, and while it's not a perfect example, it's an illustration.

The problem is that butterflies are too small to really change anything, but for larger things, such as airplanes or cumulus clouds, cumulus clouds can have an effect on the climate anywhere, and their presence or absence can change the atmospheric circulation around the clouds, and when cumulus clouds change, they will slightly change the atmospheric circulation over a larger area, and then on a larger area.

For the butterfly effect, very small uncertainties for the weather over a larger area also make almost the same climate characteristics change over time, but for a larger area (e.g., within a diameter of 168 km) the uncertainty will completely override any effects of the butterfly effect.
