Are Complex Systems more than the sum of their parts? What does it even mean?
We often hear that complex systems are "more than the sum of their parts." But what does it mean? And is it even true? In this video, we'll discuss how this concept may be confusing and how to shine some clarity on it.

Thanks for the videos. Your articles and python notebooks help me think about my research, which is about identity constructions in social networks. If you can, I encourage you to share more videos like this on TH-cam, because content like yours is very hard to find.
hi can i use this application for my bachelor degrees thesis?
Did you guys ever stop to think that maybe your data computer modeling and all your prediction research is just a bad idea and won't work? You want to know why anti-vaxxers are anti-vaxxers, why neutral people have more in common with the anti-vaxxers and why pro-vaxxers have nothing in common with either of them? Well for one thing, the pro-vaxxers our intolerant of anybody who thinks differently than them. They don't engage in debate, they don't listen to reason, and they're very selfish and snotty, isolate themselves to the people that are just like them. There's a reason why people call them sheep. Anti-vaxxers don't have some sort of magical skill that makes them able to psychologically manipulate people and convince them to not get a vaccine. Anti-vaxxers are just good at making their case based on the inconsistencies within the messaging. Mutual people are more open to debates as well as taking into consideration both sides of the arguments. When the pro vaccine people aren't willing to even engage in debate or make their case for why they are pro vaccine, And listen to the other side why they're anti-vaccine, then of course the neutral people are going to flock to the the anti Vax side. Now the reason why anti-vaxxers are anti-vax and why their is so little trust in these institutions, is because they aren't stupid. They pick up on inconsistencies and patterns, I know how to use common sense. In all honesty the institutions did it to themselves. People became super antivax and stopped trusting the institutions, because the institutions kept contradicting their claims, started name calling, telling people that what they were seeing and hearing right in front of their eyes and ears was not happening and by trying to force people to do something that they didn't want to do, using coercion by proxy. Calling people names and using divisive rhetoric just pissed them off, making them even more determined to make their case. Using government policies by trying to force people to get a vaccine and saying that they would lose their jobs, Not be able to go and get groceries without a mask on, I'm trying to restrict them from being members of society pissed them off. And repeating something over and over and over again, or saying one thing and then saying the exact opposite the next day and then denying that you said the thing that you said, was just plain as day to everybody, And really started to piss them off. They're intelligence was insulted, their feelings were dismissed and their lives were threatened. When have any of those things ever resulted in anything good? It's almost as if the people in the scientific and academic fields are trying to use data to figure out how humans and societies work, but they never leave their little bubble inside the institutions and just go out and talk to real people and listen to what they have to say. The way that the social sciences and health sciences with research and development has been done, has been a colossal failure over the last 150 years, and has destroyed so many lives. You can't use humans as guinea pigs and science experiments for research, And not all humans are the exact same. As people evolve, so too do their thoughts feelings and emotions. People are getting smarter and wiser. You will never be able to predict how something is going to happen or predict what somebody is going to do, And it's time that people start to realize that.

Excuse me I want to model user’s perception about AI fairness , it’s almost look like modelling consumers feedback, what is the best model to choose for this ?
THANK YOU! It's really hard to find videos on changing the topic. I've been trying to find videos on changing from the MA to the PhD topic.
They are called turtles because NetLogo is based on Logo, an old educational programming language used for geometric problems, where you controlled a cursor called turtle, moving it with commands like fwd 10 (to advance 10 steps) and rt 90 (to rotate clockwise 90 degrees). Great content btw.
480 views is blasphemy, this is a super important find! On some level I was always aware of their "yes, but" approach, but this puts everything in context and I believe it would be a political game-changer in people were to be better educated on this topic.
need a proposal format for physcs
If you hack here you are caught by Smith. 😊
Correct, NetLogo is a multi-agent programmable modeling environment used for simulating natural and social phenomena. It's primarily used for creating simulations rather than performing symbolic computations like Mathematica.
Thank you for sharing such a nice video. The steps and the way you explain it, are amazing. Can you tell me how to get a draft of the proposal?
I have a question regarding toy models. If they are only useful to explain how certain stylezed rules might lead to some stylized outcomes. What then is the purpose of toymodels if they only remain stylized and can not say anything useful about the real world?
Hi! It's very interesting and insightful for learning deeper about the NetLogo! I wonder have you ever used it for an evacuation scenario?
Very Interesting! Thank you so much!
Small changes in inputs leading to large macroscopic results is pretty much a hallmark of complex systems as I understand them. Good illustration of that.
👍ℹ️
I think that in reality, there are a lot of hindrances as to why people wont move that easily (money, time, energy, opportunities to gain a place in a certain space). But again, then the need to be close to someone similar could for instance be greater, so we over time anyway will see this effect.
thanks for the video presentation!
hi dino, I do really interest in exploring more about ABM. I'm from urban regional planning background and I think this modeling is suitable for me. is it possible to you to make tutorial about integration between GIS & ABM approaches in the context of travel mobility. thank's
Hi! I'm not really knowledgeable of abms of spatial mobility, so for sure I won't be able to do it in the near future. But maybe in some time I'll go back to it!
Sad to see that the promised video on classical mechanics and quantum mechanics never got made. I think I know some of what that video would have talked about. I had a one-on-one reading course with a professor on his PhD thesis which covered how the rules of classical mechanics can be derived from quantum mechanics by taking the limit h goes to 0. So when people claim that quantum mechanics replaced classical mechanics, they completely miss that classical mechanics is contained within quantum mechanics.
Interesting channel. Thanks! I would be interested in a video that breaks down an ABM model from a paper and shows how to implement it in Mesa or Agents.jl.
Thank you very much for the idea! I don't know julia, but I may do it with Mesa!
@@socialcomplexitydinocarpen6372 I would make the conjecture that in your video about "the Whole is more than the sum of its parts" you neglected to explore that the Whole creates a Surplus by accumulation/concentration/transformation of some quantities and qualities and the reduction of other quantities and qualities which the disjoined parts can never do. You said in the video, The sum is the disjoined parts plus the interactions between them, but I would add, which then create the Surplus. In other words, the Whole has capabilities which none of the parts can have. You want an example? Yes? The human brain is made of simple agents that perform 1) a very simple task of getting excited under certain conditions. 2) They communicate their excitement very well 3) They are very well connected The Surplus , a.k.a the added "more", by these simple agents called neural cells results in .... a human civilisation with rockets, music, arts, science, etc. ... which none of them can do alone or if connected poorly.
I fear you somehow miss the point of "classical" social sciences. Social sciences will never bent to numbers and computation, and that is in no way related to an early stage of these fields "recently" emancipated from philosophy. Great minds have sorted this out : equations are no adequate language to conduct research on humanities and get insightful results since you cannot define human-related objects the way mathematicians do. Maths and models would be the easy way, but, beyond improved data as you mention it, they are intrinsically vain (liberty and creativity are by definition what exceeds models) and not adequate (bias seem impossible to overcome) to describe humans. This is not a matter of stage or progress in science but a matter of the nature of the studied objects vs the methods of empirical science. So I strongly doubt you will ever get the basic pinciples you hope for because you cannot standardize (let alone measure) what is not even possible to define. (For example: how to define happiness ? Neurochemistry will never get us an useful answer apart from measuring some brain's variables and most will agree that hapiness is not a scalable object, but we can certainly get some leads from psychology, sociology, philosophy and arts .) Actualy the point of social sciences may reside in the neverending quest of defining its objects, tools and purposes, offering along the way contradictory and disputed insights. Now thanks to computational social sciences we can maybe obtain unprecedented data and build some reliable predictive model of an angry crowd's behaviour but we will not get any closer to describe properly their anger and to understand what people crave for, nor to help them formulate, understand and obtain what they desire, nor to predict what kind of system of government could possibly emerge after their uprising - and there lies the point of social sciences. I hope I do not try to reinvent the wheel. Very interesting content, thank you for your insightful perspective from computational social sciences, I learned a lot !
very interesting, thanks for the explanation!
Thanks for your comment! Definitely, math (at least in the way we used in physics) is not the way. Measurements in social sciences have a certain vagueness that cannot be removed, so we really need to figure out some ways to deal with this. However, in the future, we may still be able to pinpoint some kind of basic principles of human behavior, even if I have no clue of how this could look like. It still took us thousands of years to invent the tools to understand physics, so it may take us quite long to develop tools for better understand/model/represent humans. Also, as you already mentioned, we could probably do a reasonably good job on the behavioral (i.e. external aspect) while the more psychological aspects may remain a mystery forever. Personally, I feel quite confident we can do a good job on systems with thousands/millions of people as they do not depend much on the psychology of the single individual.
interesting that dino comes from a solid natural sciences background then switched to social sciences. very interesting but also very challenging field.
I think they are both very challenging but in a very different way
this is really very interesting Dino, do you have Python code as well? I am curious as to how you go from the survey answers to the weighted network.. then visualisation is I guess one of the usual layout algos?
Hi! Yes, we have an entire tutorial for python here: www.resinmethod.net/python-0/ And many other resources in the main website: www.resinmethod.net/ For that specific visualization I am using Gephi, but any force-directed method will hold very similar results (there are also some native to python)
Love the quality improvement on this one!
Ok, I'm finally back on TH-cam! It took me quite a lot of time, but this time we should have many more videos coming up. I know many of you wrote comments to older videos, so in the next days I will start by responding to those comments. In the meanwhile, if you have any questions, comments or ideas, let me know here in the comments. Ciao!
Could you make sure there is at least one comment in each of your videos so that I can comment by replying to a comment. TH-cam does no allow me to start a comment. It only lets me reply to comments.
thank you for this amazing video, it was really insightful! I had one related question on MSCA PF, can we submit more than one application (with different supervisors) for the Marie curie postdoctoral fellowship?

Thank you, very useful content, well presented!
wow. interesting game. what were the technologies you used in building this game?
If by technology you mean something like the coding language or software, I have no idea. Maybe on the website of the author it is possible to find this information. However, the structure of the game is built pretty much on game theory
agent-based model also applied in travel demand modeling, yes that's also part of social science and a game changing for transport modeling, you're dong great job.
Hi, I really appreciate your effort in explaining this process, if u can drop your email I would like to email you personally. thanks

Sono d'accordo!
@@socialcomplexitydinocarpen6372 yesss
Very interesting! Good explanation of yours! I'd like to use Agent-Base model to test an hypothesis in Education.
If you want to share your idea let me know! If it's not too hard to test we may have a video on that
but how affected is the result by other variables like mutations (change of behaviour) and the other parameters. where does the result converge to with differnet initial conditions?
It really depends on what you have in mind / what is your research question. For example, more mutations in general will lead to less clear pattern (as mutations are almost re-initializing part of the simulation each time). But to give a clear answer we also need a specific research question.

just found your Chanel random- thrilled to hear more ! greetings from germany
That was a really nice introduction. And I liked the jokes in-between :D Good job! You've got yourself a subscriber
Will you also cover some literature? Like sugarscape or significant models from the last decades
Hi! Yes, I am working on two different series which will cover the literature. One is more simulation-oriented and it's already ongoing. We analyze some popular models (e.g. Schelling's segregation) and we try to link them to real-world applications/meaning. (See for example -> th-cam.com/video/H2jauYgKFcE/w-d-xo.html) The second did not start yet, and it's going to be more paper-oriented. So it's going to be a little more technical and it would be for people who want to get more into the details of abm. If you have any suggestion or model that you would really like to see, just let me know!
