Butterfly Effect Definition

butterfly effect

Hello Time Travel Fans

You all heard about butterfly effect but what exactly is the butterfly effect definition and how this term came up? So in simple words we understand that butterfly effect is when a small action has a huge chain reaction, a small thing can change the flow of life later.

Who came with this definition?

Edward Lorenz derived this term from the example of a tornado influenced by the wings of the small butterfly. The pattern of the tornado could be changed just by the flapping of the wings of a butterfly. Impressing how so minor facts can have so large effects.

Edward Lorenz came with the name but before him the butterfly effect theory was demonstrated by two other scientists, a french mathematician Henri Poincare and American mathematician Norbert Wiener. Edward Lorenz presents his discovery in 1963 in an article that at that time not many scientists noticed.

It was in 1972 in a lecture Lorenz gave at the annual meeting of AAS (American Association For The Advancement of Science) when he said ‘ A butterfly flapping its wings In Brazil can produce a tornado in Texas’. So these words were noticed by the scientists at that time and this is how Edward’s Lorenz discovery become one of the greatest in twentieth century physics.

I don t want to come with boring, tiring theories but if you just watch the video below I am sure you will understand what is exactly the butterfly effect and how our choices, decisions we make can change events. Also here you can see on a global scale how a small event can change history.

Butterfly effect theory was an important inspiration also for cinema. I will tell you a few titles that are based on this concept and really worth watching;

Donnie Darko (2001)

Butterfly Effect(2004)

Looper 2012

About Time(2013)

Predestination (2014)

So thank you for your time and I would like to hear your opinion about this concept. If you could chance something that would affect the world history what would you change?

I have always been interested in time travel. From a very young age I was forever watching movies that would take me back in time.

I would love to hear from all of you who are also interested in this subject. Movies? Science? Book? Literature?

Whatever your interest is, I would love to meet you.

    A very interesting video with an interesting theory. It is amazing to think that slight changes can alter entire weather patterns.

    It’s amazing that such a seemingly small action from a hitman caused such chaos and an entire world war to break out. But as the video suggests, things might have been even worse had this not happened, so maybe the saying is true that everything does happen for a reason.

      I am glad that you enjoyed the video. It is interesting and in the same time scary how each decision we make can change the world. Even a small flip of the wings of a butterfly….who would think this?:)

      Thanks for reading and of course everything happens for a reason.

    Hi Cristina Boros,

    I have read your full article and understood that the butterfly effect terms is used for any types of chain reaction which looks like a butterfly shape. I would not even know that scientific theory if I did not read your article. I am going to share it with my friends so that they will know this theory also. Thanks for sharing this informative article.

      Hello there? Looks like a butterfly shape? No….means that if you do something so small as a butterfly flap of wings can have huge effects on the Universes flow of things.nothing to do with the butterflies:)

    Very interesting subject! I watched the video explaining the butterfly effect and it got me thinking…What if I had not stumbled on this website, I would have never heard about the butterfly effect. It seems that this is a never ending theory and someone could probably go mad if they would keep on analyzing every little moment of their lives and try and alter their future with this “effect”.  It’s almost like this other theory “every action has a reaction” kind of thing.

    I do realize that we have to live our lives and not “sweat the small stuff”, but this theory has got me thinking very differently.  I guess we should sweat the small stuff to a certain extent, but we never know what it will affect. So even though the butterfly flapping its wings in South America may cause a tornado in Texas, no one knows that when it happens in Texas.  

    We should just go on and live our lives in the best manner possible and then the effect should bring us good too right?  Basically, I see it as the “Law of Attraction”.  Do you agree?

      Yes,Denis I totally agree with you.As much as we want to think we never can prevent all the possible effects of our actions. Who knows, maybe if you cross the street one day, you  delate for a minute a car passing the traffic light and you save somebody’s life from a possible;e car accident later on…just a few seconds make the difference.

      Thanks for reading and i am happy to see you soon on my site.
