The way I always understood The Butterfly Effect is that one tiny little difference can go on to create 2 differences that go on to create 4 differences, that can go on to create 8 and so on, not exactly to those numbers but the point being that a single point of change can compound into many changes that can lead to a big changes down the line.

[@mistrants2745]

Thats exactly what it is...

[@xDmparto]

Your definition is more like "Chain reaction" than Butterfly Effect I guess? More often people call it "Domino effect" but it's more or less the same without make the explanation to long.

[@DigitalArchmage]

​@@mistrants2745 yes, but that's not how he described it in the video, so it's relevant. He kept saying "the butterfly causes the tornado" - but he could be describing it as "the butterfly causes things that lead to other things that lead to other things that cause the tornado". I've also heard 'butterfly effect' more to do with time travel than weather, which is another point. We don't have another universe to compare a single difference with. We can never know 100 of the necessary conditions that led to anything specific.

[@avhuf]

I also think you're missing the point. It's not like the flapping of a butterfly gets magnified to a tornado as you seem to suggest by your geometric sequence.

[@DigitalArchmage]

​@@avhuf I didn't mean to say it that way and and I feel thats' the way the video describes it (as magnified) and thus objects to it. I think people should object to the idea that it's magnfied (and this was meant to be my point). It only directly causes the next event, which is another link in a chain. It also doesn't *always* turn into a tornado. We can't know it's necessary for the tornado, but it could be.

It's not even that clear that "the butterfly effect" is named after the butterfly flapping it's wings. One alternative possibility is that the Lorenz attractor actually resembles a butterfly.

[@juzoli]

I think your problem is not really with the butterfly effect. The theory is just fine. The problem is with the general INTERPRETATION of this theory. Many people think that these small changes WILL lead to big changes in the future. But usually they don’t. Some changes will lead to big changes, but most of them don’t. The focus is on the UNPREDICTABLE nature of it. So we have absolutely no idea which small change will lead to a big future change. I like to think about it the other way around, starting from the effect, not from the cause. Think about ANY major thing around you or in the universe. Your birth, the existence of a tree, the orbital distance of the Earth, whatever. For every single such thing, you will find some minor event in the past, which if happens a bit differently, it wouldn’t exist today or would be very different. The butterfly effect only works in retrospect.

[@AmusicsiteCoUk]

Indeed I think it's his interpretation that's the problem. I have never taken this at face value that a butterfly could actually start a tornado. More that one of many things, like for example a butterfly flapping it's wings could start a tornado. Implying that there are many possible things and in a complex system possibly too many to say for sure which one.

[@Raykkie]

He never said he had a problem with the theory. Also it's not an arbitrary single change that changes a specific thing, it's almost any change that lead to big general impacts

The number of butterfly flaps on earth is several orders of magnitudes more than the number of tornadoes. That means most of those flaps can not possibly lead to tornadoes.

[@OceanBagel]

I've always taken it to be more of a long-term effect, like how a small change can stack up over time to end up resulting in a larger change. Like maybe it won't diverge that much right away, but the small change can cause a different small change and eventually the changes will start to stack up. In that sense, it's more an example of where time travel paradoxes can come from.

I think you've entirely missed the point of the saying by taking it too literally. The point is not that 'a specific butterfly will cause a specific tornado', but rather that small changes over time will add up due to the chaotic nature of things. If we imagine two alternate timelines where the only difference is one butterfly, given enough time these tiny changes will result in events playing out slightly differently, which will cascade into bigger differences between the two timelines.

[@Sabarok]

What about replacing the butterfly effect with a commute? How much of an effect would leaving at a different time have on your drive? When you get to a stop sign, you arrived just before another car, so you carried on and made it to the stoplight just before it went yellow. If you'd left 2 seconds later, you'd get to that stop sign just after the other car, and then the stop light would have turned red, and everything after it would have a lot of differences on what cars are around you. It's unpredictable because we don't know what change will happen from our departure time. Maybe it's not a perfect analogy since things like stoplights will regulate the input variations, but I think it's one that's easier to understand. People have enough experience with the "groundhog day" trope in media to understand how small changes to inputs can create different outputs.

[@phagesaint]

In chaos theory, a slight perturbation should result in some drastic difference in the future. Say in your scenario, I leave the house one second earlier. There is this possibility that the one-second-earlier me and the one-second-later me sync at the first traffic light. The rest of our path is going to be exactly the same.

Regarding our first reason: Weather is a thing everybody can get as a complex system since people deal with it on a daily basis. Far fewer people can conceptualize a chaotic pendulum, let alone a three-body planetary system unless they are somewhat trained in physics. So the "butterfly effect" can at the least be a gateway into the beautiful world of complex systems.

The funny thing here is that while people do deal with weather every day, they don't get how chaotic the system really is. Just think about how most people (me included) get, let's say, angry about weather forecasts for messing things up. “How hard could it be to do a proper forecast?” is kind of a common thing to say/hear. This means they don't get how hard it is, since it's almost impossible to gather all the data at the starting point.

[@hendric93]

I think this is just an individual opinion about the first thing that comes to your mind when we say "butterfly effect". When iam talking about a butterfly effect, i dont think about the weather changing because of the swing of their wings. The first thing i think about is a butterfly you kill 100 million years ago which ends up in the humans never beeing born. Of course you can't say that this one butterfly leads to any of this. But you say that one tiny change in the past may lead to bigger changes over time which change the world or a scenario like a tornado completly. And this changes over time will happen if you only take one tiny thing out of the equation (for exaymple this butterfly). Its chain-reaction cant be forseen and changes will only increase over time (like the humans who cease to exist) The butterfly effect is a chaotic chain reaction and i personly love the name because of its simplicity and pictorial nature

[@michaeltan7625]

I think what he's talking about is how the pop science description of the Butterfly Effect gives many people the wrong idea. The idea is that in a chaotic syste, small change in initial condition can lead to big change in final condition. If someone just heard "The flap of a butterfly's wing can cause a tornado" and didn't look further into it, they probably won't get that idea.

[@depeltenburg6916]

But it cannot be seen without the change it would.. like it's so tremendous small you could ignore it. Like how likely is it compared to all the other things that can happen.. and then you see some changes are like the waves one droplet makes in the ocean... It so small ..all the other things (wind, sun, boats, fish, other waves, birds landing) its effectiveness is so far after the comma it's ignorable

[@pastusmarcus2249]

Agreed. The Austrian Archduke's driver took a wrong turn, which was what allowed him to be assassinated. This sparked WWI, which destroyed the German economy, driving WWII, which caused chaos in the Middle East and led to the prominence of the Soviet Union, the Cold War, and many of the problems we face today. Who would've guessed that if the driver paid more attention to where he was going, the world might be substantially different today? It wasn't a butterfly, but it still illustrates the point. And before some smart guy chimes in, yes, WWI probably would've started without that event, but it would've happened at a different time, and under different circumstances.

[@jogabonito8989]

@@GeoffCostanza But this is exactly the point. All that would've happened anyway and I doubt that if the war was delayed a few days you would see massive changes in the chaos that ensued after. In other words, it's misleading to say that the world will be vastly different if the driver didn't take the wrong turn. Also Henry's point was that there are many butterflies resulting to that outcome. What if the wind was 1mph stronger, and assassin missed the shot? What if the angle of which the vehicle approached didn't give him a clean shot? These are all butterflies as well which led to the event. Not a single wrong turn. I know these are just examples.

I don't think the butterfly effect misses the point of chaos, I think you miss the point of the butterfly effect. The point isn't that the butterfly "caused" the tornado. It's that the world itself is chaotic and highly dependent on initial conditions and one of the biggest ways this can manifest is in weather systems. The butterfly effect can be used to critique fiction taking place in alternate timelines or involving time travel. Or, more practically, it can be evoked to bring solace to a grieving parent torturing themselves over what they could have done differently to prevent the freak accident that killed their child. The pendulum example doesn't illustrate that.

[@Ruto513]

Brilliant comment! :)

[@Jordan-zk2wd]

I agree with what I think(?) was Sean Carroll's critique of using the butterfly effect to critique fiction, which is also something that I think is something often missed when talking about chaos that Veritasium highlighted super well: there are tons of patterns we can observe and predictions we can make with chaotic systems actually if look at families of chaotic trajectories (which may have attractors), and in particular we have no reason to think that social structures or certain historical circumstances for example aren't effectively attractors of a chaotic social system. If Hitler didn't come along for example, some other charismatic germanic person would have cobbled together all the popular ideas of that time and place (which is what Hitler did basically, he wore his influences on his sleeve tbh), they very likely would have caused a world war, and they very likely would have lost. Now, certainly some works can go too far in not changing stuff, Bright introduces giant differences in it's world and fadt forwards like, what hundreds of years, and everything is pretty much the same. But in general there is no reason to expect that the vast majority of possible alternate histories with small scale tweaks would be fundamentally different anymore than a butterfly flapping its wings would be the tipping point that creates a tornado.

@@Jordan-zk2wd ok, so hitler was a product, but what about those great personalities that changed the world? if any of them had chosen a different path we all could be in a very different situation. and it doesnt require much, maybe it was just a meeting they had that gave them a great insight and if they couldnt meet they wouldnt have that or it it could be delayed for years.

This is taking the butterfly effect too literally though. Seems almost like purposefully missing the point. As a thought experiment, it's simply stating that a minute thing can have a large effect. i.e, some child leaving their ball in the middle of the road which causes a car to swerve to avoid it, the time it took to swerve the ball means the car hits a red light they otherwise wouldn't hit, meaning they're late to work at their government job, which could lead to a war starting or something Yes, there are numerous things that could have caused the person to be late to work, but the child is a "butterfly" in this example, if the child didn't leave the ball then they would have gotten to work on time

And the disagreement is not about the physics. He's saying (among other things) that describing that as a casual relationship is not a good choice of terms. For the child with the ball above, I wouldn't blame the kids for making the guy late to work. The level of causality they had in the scenario was low. If the lights had been different it the other car had been in a slightly different place or thousands of other things, the guy might not have been late. (But if the kid was blocking the road and refusing to get out of the way for five minutes, then maybe you would attribute blame to the kid even if maybe the guy could have made it if the traffic could have worked out just right.) Henry is not saying that you, someone who understands physics (and watches Minute Physics), doesn't understand what the butterfly effect really is.

[@LowVoltage_FPV]

I recall a science fiction story where someone goes back in time to the time of the dinosaurs. They inadvertently kill a butterfly. When they return to the present everything had changed. A small change like that had cascaded over the millennium to grossly change the present. I had read this when I was young and when I first heard the current usage of the term, this was what I thought it meant.

[@Mutheim]

I think a lot of people misunderstand the butterfly effect wrong, and this video has traces of the same misunderstanding, especially in part 2. A lot of people think of it as a kind of cascade. To take a different example, imagine a small grain of sand falling down a mountainside. It can collide with a slightly bigger grain, which in turn collides with some unstable pebbles and so on, eventually unleashing a rock slide. This seems to essentially be the picture people have in their mind when they think that the butterfly "causes" the tornado. It requires an unstable system near the "tipping point", and the way the video talks about causality would be applicable in this rock slide scenario. The extraordinary* thing about chaotic systems is that they are in a sense always at a tipping point: _ANY_ arbitrarily small change in the initial conditions _WILL_ eventually lead to a divergence in the final state. This means that if one butterfly flaps its wings once, then after a long enough time, the whole weather pattern on earth would be different than it would have been if it didn't flap. In this sense, not only can a butterfly cause a tornado at some point in the future, but it always will! Of course, as a chaotic system, it is essentially unpredictable, so it is still not possible to make a causal connection between a specific butterfly and a specific tornado. This fact that it is not possible to make this causal connection becomes even more obvious when you keep the "too many butterflies"-effect in mind :) (*Once you understand chaos, the fact that any butterfly will cause a tornado doesn't seem so extraordinary anymore, but instead rather natural -- which is perhaps even more extraordinary in its own right)

[@obviouslymatt6452]

I think the point is that 10,000 years down the line, it’s possible that there could be a hurricane where otherwise there wouldn’t have been, due to that butterfly. But the important part that most people miss is the long time frame - as you said, the situation would have to be set up perfectly for it to happen a short time after the flap.

[@tejing2001]

The other issue I've always had with the stereotypical understanding of the butterfly effect is that people think that the effects of a small change in initial conditions would somehow be extraordinary, when in fact they would be quite ordinary, just different. The butterfly flapping its wings causes a completely "reroll" of (for example) when tornados happen, if you look far enough in the future. Indeed, just about any perturbation does so. But that "reroll" is still according to the same probability distribution, so although different things happen, they're still ordinary things.

[@joaoppagnan]

I didn't understood it like this at all, lol. The Butterfly Effect was meant to be an analogy to a property of chaotic systems that a tiny little difference in initial conditions can cause a very different evolution in the long run (sensitive dependence on initial conditions), and not as a cause to why there are tornadoes. Edward Lorenz used it in meteorology because he was a meteorologist, but the idea of sensitive dependence on initial conditions is applied to all chaotic systems (like the chaotic pendulum you've mentioned). And the unpredictability of those systems isn't because of probability, after all they're deterministic systems, it is because of this and other properties. Source: Chaos, by James Gleick; and other chaotic systems books I've studied in my undergraduate research. I think you've interpreted it too literally. EDIT: And the attractor of Lorenz's system kinda looks like a butterfly, so maybe it was from there that he got the idea for the analogy.

[@theclassypineapple]

I interpreted the butterfly effect analogy to be the same as your "too many butterflies" analogy. Butterflies are very tiny, and therefore specifying them as a cause puts an emphasis on the fact that there's many many forces affecting the system that are equal to or greater than the force of a single butterfly flapping it's wings, yet removing or adding any single one can cause drastic changes, therefore making it near unpredictable.

[@doublej82]

I've always interpreted the Butterfly Effect as how you described the Too Many Butterflies Effect. I've never thought of the butterfly being either necessary or sufficient, but's more of a "but for." The idea that the tornado wouldn't have happened but for something so small and unrelated seemingly implies that there are so many "but for"s that it's impossible to account for them all. If that makes sense. My head hurts now so I need to go for a walk in the woods.

I think the butterfly effect is more of a thought experiment on how a minute, seemingly insignificant change can be the tipping point for a major event; rather than a minor change being the sole causality of a major event. Consider the straw that broke the camel's back. We don't jump to the conclusion that a single piece of straw can rupture the spine of a camel, rather that the tipping point for that rather catastrophic failure can be attributed to a final, minor action. Butterfly that broke the camel's crocodile tears.

As you said, a system doesn't need to be crowded to be chaotic. So blaming 'too many butterflies' for the difference between two futures misses that the states could diverge even when the initial states differ only by one butterfly. It would lead into thinking the double pendulum won't be chaotic as there aren't too many changes you could make to the initial state - so there aren't too many butterflies.

I feel like there is too much focus on the butterfly causing a tornado part. When in reality a the Butterfly Effect was just "A small change can result in large deviations in the future". You said it yourself, people don't go around worrying about Butterflies flapping their wings because we don't see any causality in the Butterfly to Tornado relationship. "Chaos is about non-linear systems that are sensitive to their initial conditions and are very hard to predict. The Bufferfly Effect kind of makes it seem like we can predict that if the Butterfly flaps it wings a tornado is going to happen. ....[The Butterfly Effect] places to much emphasis on causality and predictability when the whole point in unpredictability" You claim the Butterfly effect places to much emphasis on predictability, ...why? It uses such an outlandish claim (Butterfly->Tornados) that no one could ever hope to come up with any such predictive models. It's core example is meant to show the two criteria you laid out for chaos, it would be ridiculously hard to predict, and almost certainly highly sensitive to the initial conditions On a side note, most media utilize the Butterfly Effect to show unintended/unforeseen consequences. I'd argue that also shows a strong belief in the idea that the Butterfly Effect represents chaos in the modern zeitgeist.

[@dragonbretheren]

I've always heard the phrase Butterfly Effect being used in time travel as an example of long-term knock-on effects from a seemingly small insignificant change. This is the first time I've heard the tornado chaos theory version of it. The point (at least to my understanding) is not to look at a butterfly today and try to guess the effects it will or won't have down the line, it's to compare a previously "known" version of history versus an altered history where a single butterfly from several years ago is removed from the equation. For a vastly oversimplified and accelerated example, with that butterfly prematurely killed by a time traveler's careless footstep, it no longer pollinates a specific flower in a specific field. Because that flower is not pollinated (or perhaps pollinated at a later time by a different insect), it does not become the dominant plant in the area. Because it doesn't become the dominant plant in the area, a larger animal that otherwise would have eaten or used the results of that plant doesn't habitate the area. Even if we stop here (side note that this would have taken place over several years), we have a measurable difference from the original timeline (i.e. this field was formerly known for its dense rabbit population) to the new altered timeline (no rabbits in this field, or less so if the process was started later by a different insect).

[@isaz2425]

it can also affect human society through the weather : with a single butterfly missing, the weather will be different, that means every human activity outside is affected , in one case it might rain, making some people to change their plans , so there will be new people who meet each other in one version of the universe and not in the other. different couple will form, and different people will be born. and after a while every human on the planet will be different than the ones who would have lived without this butterfly.

[@alexplorer]

From the comments, it's pretty clear people don't understand the Butterfly Effect to begin with. There are probably great videos I could point to, but here's a quick summary: If you have a complex mathematical model of the weather and plug in a value for one of the many variables to be something like 4.36234341, you'll get a model of the weather that you can then extend outward for a period of hours, days, or maybe even a week. But then you re-run the exact same model with all the exact same values except that you leave off the last digit so that it's now 4.36234341. The model gives the same results at first, but then the predictions for the 2nd day are a bit different, and by a week out, the output describes a completely different forecast. That little difference of .00000001? That's the equivalent of the input of a butterfly flapping its wings on the other side of the world. There's nothing significant about that butterfly; it's just that little differences in the beginning can create big differences down the line. Or not (because sometimes they don't). The point is that you can't know specifics.

For my part, I try to treat it less as a *direct* cause of the chain of events that leads to the storm, but a demonstration of a different *pattern* of events that leads to the storm. In isolation, sure, a single butterfly's flap won't cause a tornado. But in combination with other factors and variables, that tiny air disturbance can grow into a storm. Or it could not, and another factor might cancel it out. We don't live in a vacuum, after all. Other variables are just as important.

3:10 "Tornadoes happen without butterflies." Bold statement. Is there enough evidence to verify this?

[@ZMattStudio]

My understanding of the butterfly effect seems to be wholly different than yours. It was never that the butterfly causes the tornado, but that the presence of a particular tornado at a particular time could be impacted by something as small as a butterfly. The emphasis was never on predictability but on scalability, and the too many butterflies misses that since the scale remains massive. In fact, if I recall correctly the butterfly effect comes from a sci-fi story about time travel, the point of which was that even the smallest, least significant of changes can lead to a large and quite significant future impact.

[@brianpso]

You missed a big one, the effect of the butterfly's wing flap dissipates so quickly that its range isn't enough to ever cause a tornado. There's no chance for a chain of events to be triggered by a wing flap and build up to a tornado since its influence is so small and the system it's inserted in tends toward equilibrium so fast in comparison that it ends up not having any meaningful effect on the system.

[@mastershooter64]

[@garanceadrosehn9691]

I enjoyed the points you made on the specific term of "butterfly effect", although I never took the phrase to have the meanings that you talked about. I started out in computer programming a few decades ago, and weather simulations were a task that programmers thought we *SHOULD* be able to get right, but found out it was much more challenging than expected. And the issue was much more subtle than the need to crunch a *massive* amount of numbers, therefore those issues could not be solved by simply building bigger and faster computers. Even the tiny amount of round-off error caused by printing out intermediate results could make a huge difference in the final result, and those tiny errors (which *did* cause serious variation) were described as "these round-off errors about as significant as a butterfly flapping its wings". I'm not saying that's the official source if the phrase, I'm just saying that's the context where *I* first heard the phrase come up. However, I can see how the phrase when taken by itself does make it sound like butterflies are causing tornados, and I think this video did a good job of dispelling that notion, and saying *why* that notion doesn't make sense.

[@Raykkie]

Too Many Butterflies is sadly still easy to misconstruct. Having too many butterflies would seem to imply to the average joe that there's just too many initial states to keep track off, which is kinda of the opposite of the notion that should taught. A chaotic systems is not necessarily a system that has too many initial conditions, but actually too many possible future states. It's basically entropy of information, the more the system changes over time (or grows, as you now have to keep track of more time and therefore information), the more information is required to predict a likely outcome

I never interpreted the butter fly effect as to causing the tornado - I interpreted it as the tornado was going to happen but the weather system that is going to cause the tornado might have been travelling in direction x, but a butterfly flapping it’s wings caused a minute change in direction of travel of that weather system resulting in a different town suffering the tornado on the other side of the world.

I like to think of tossing a stone down a hill. In most cases, we can make pretty good predictions about the general behaviour of the system: the rock will end up at the bottom of the hill, and probably on the side of the hill it was tossed from. But tiny little changes to the exact parameters of the toss and the shape of the rock will cause the rock to land in different places and follow a different path, and the outcome doesn't change smoothly when we smoothly change the parameters of the toss. Also, if the hill has a ridge, then the rock might go either side of that ridge, making a big difference in the outcome. There is indeed, on a particularly unstable hill face, the chance that the rock could cause a landslide in certain configurations, and so we get a "butterfly effect" here. But the point isn't that tossing a rock slightly to the left can cause a landslide, but that the system is unpredictable, and if you set your system up so that certain patches have massive observable effects, then yes, those effects are indeed potential outcomes of the system, and it'll be hard to figure out what exact set of parameters may or may not "cause" them.

I feel like this video kind of missed something, like the point of the butterfly effect, in which it's description poorly describes too. After a long enough period of time that butterfly flapping it's wings once is enough to change the entire weather system from there-on-out, effectively participating in causing every tornado from a certain point onwards. But if it didn't there'd be an entirely different weather system with an entirely different set of tornadoes which we can't say would be better or worse. And this applies to every single action anyone or anything takes (assuming free-will).

[@adityakhanna113]

I have had any issue with the framing of the statement but maybe the sentiment is "there are two possible initial states, in one the butterfly flaps its wings and the other it doesn't". One in which it flapped might have a tornado while other may not, because of the flapping somehow. In simple systems, the rate at which close initial states separate is slow, so it will take a long time. But in a butterfly scenario, too many butterflies can push the "two states" away faster

[@posthocprior]

What are the parameters of the many butterflies? What if it’s less than three? Less than two? Your hypothesis is valid, in my opinion, if the boundary conditions are significantly greater than 1.

Very interesting point! The complexity of weather conditions is an unnecessary and confusing aspect. Simple systems can also be chaotic (and more accurately affected by the flapping of butterfly wings).

[@NightmareCourtPictures]

There's actually a huge misconception about the double pendulum example as, in the same vein as the butterfly effect. A double pendulum is not a simple system, it is complex. The reason is because the observer is ignoring parts of the system, paying attention to just the pendulum, when in reality, the pendulum has a sufficiently large state space: a space of states in which the pendulum could be in some configuration in that space. Say you had a 2x2 grid, and this pendulum was in this grid, where we describe the pendulum as a black square, and where the pendulum is not as a white square. the pendulum can only be in 1 of 4 states, and if the pendulum is following some rule that governs where it will appear, it will appear deterministic to us because we can easily keep track of the entire system. Now extend the example to a 1000x1000 grid, and we blow up the pendulum just a little bit to be some number of black squares. In order to keep track of the pendulum, we need a full description of the entire state space, even if it behaves deterministically, because any square that we "miss" will create uncertainty as to which squares get filled in next by the deterministic rule. Thus a pendulum in a continuous space, even though it seems simple, has a state space that is sufficiently large, that we don't keep track of and therefor the pendulum is complex, and will exhibit chaos. You can also think about a real pendulum in a room. You notice the pendulum swinging around chaotically and you assume it's simple...but your not keeping track of all the air molecules that are bumping into it at any given moment in time...and therefor one is omitting a valid description of the true system, which is the pendulum and a bunch of air molecules.
