Our world is filled with an abundance of data. Albert-László Barabási, a network scientist, believes that understanding the underlying structure and relationships of complex systems is crucial. Barabási’s research has challenged the notion of random connections and led to the discovery of a more accurate representation of how these systems are organized.
Barabási’s exploration began with the vast internet. Surprisingly, he found that the intricate web of connections did not follow random patterns but instead followed a power load distribution. He named these networks “scale-free networks.”
Barabási’s groundbreaking work reveals that new connections in our networks tend to form with already well-connected elements. Scale-free networks exist in various complex systems, such as cellular interactions and social networks. This discovery is an important step toward comprehending the remarkable complexity that arises from countless interactions among the world’s many components.

About Albert-László Barabási:
Albert-László Barabási is a network scientist, fascinated with a wide range of topics, from unveiling the structure of the brain and treating diseases using network medicine to the emergence of success in art and how science really works. His research has helped unveil the hidden order behind various complex systems using the quantitative tools of network science, a research field that he pioneered, and has led to the discovery of scale-free networks, helping explain the emergence of many natural, technological, and social networks.
Barabási is a Fellow of the American Physical Society. He is the author of The Formula (Little Brown), Network Science (Cambridge), Bursts (Dutton), and Linked (Penguin). He co-edited Network Medicine (Harvard, 2017) and The Structure and Dynamics of Networks (Princeton, 2005). His books have been translated into over twenty languages.

What's a hidden network that you find fascinating?

@gkwilly716 11 ай бұрын

I used to be an uber driver and was fascinated by the patterns of how people travelled over different parts of town. It was like there were gravity wells that pulled people into certain hubs.

It's the first time in my life I heard the average person knew 1,000 people, with the one knowing the least people having 850 names in their ready to recall mental Rolodex. That's amazing. And I speak as someone who took tons of sociology courses in college. I personally don't know more than 50 names; and that's being generous.

Actually I disagree. Your channel caters to a population that is already well educated and has the capacity to understand this. However, I would say that a large majority of people would be very confused about what he is trying to explain. For example, let's say you took 100 people who were shopping at a Wal-Mart and had them watch this, I would say the vast majority would really have no understanding whatsoever about any of it. I'm not sure what this channels goal is but if it's trying to improve information access and understanding of our world then you need to take into account that most people won't get this. I know that the universe is complex. But you're really only talking to a subset of our population.

Like mushrooms and mycelium networks, our interconnectedness with the world around us is essential for our survival and well-being. Just as mycelium networks support the growth and health of entire ecosystems, so too can we create systems that support the well-being of our communities and planet. By recognizing and harnessing the power of natural networks, we can work towards a more sustainable and interconnected future. It all starts with learning from the wisdom of the Earth and embracing the power of mycelium and other natural networks.

It's interesting if there can be an algorithm, that can grow the whole network, starting from a single node. We have algorithms for fractals, so why can't we have them for networks? In physics, edges, connecting nodes may be associated with time(causal sets).

@anywallsocket 11 ай бұрын

You definitely can. If you want a proximity based scale free graph, you can simply sample a random point and add a node or link there if that point has a certain number of nearest neighbors. This will generate fractal structures similar to diffusion limited aggregation.

However, for a long-tailed, power-law type distribution, the controlling influence is concentrated at the largest sample value (assuming a finite sample population).

@@antonymossop3135 It should be noted though, that Scale-Free is referring to a symmetry property called scale invariance. That property is responsible for systems to look self-similiar at different scales. If you think about how a fractal works, there is no "biggest" or "smallest" or "controlling" component of the thing, all the components are interacting with each other invariantly under that transformation. So specifically, it means that there is no "controlling" influence, it's the opposite, that there is no centralized control in such systems. That there is control at all scales. One of the tenets of C-Systems, is that C-systems are hard to disassemble in that way. It's like asking what the "real" shape of the Mandelbrot set is. It no longer makes sense to ask such things because there is no scale at which the shape of the Mandelbrot set is "the real one." You can make similiar analogies to complex systems like economics and biology. The list kind of goes on.

like spiders, ppl (an old net running on physical connections and desired-good) construct pipes that pass d-g between physical locations creating new networks. But events running in any net can effect the spiders, can promote another net reformation. So, Can we describe each net influence on the growth of a propagating event?!?!, by matching growth graph to Event-growth graph per net , that was recorded and confirmed to be "the most-impactful carreir net for that event". And, If "close enough"graph match, we can? reduce the problem by removing the net and it's impact from the analyzed group of networks while correcting the analyzed growth graph.

Scientifically this is academic thinking and then...here we go, I can't resist...politically the same academics push a complete opposite way of thinking: the outliers matter, not the average. I find these two modes of thinking so outrageously inreconcilable and yet 'they' do it and no one confronts academics that they must make a choice between these two modes of thinking.

Cool story. Did you ever listen to the definition? It’s anyone you know on a first name basis-that’s what they’re calling a friend. So everyone you encounter at work, neighbors, probably most everyone you grew up with…even if you haven’t seen or talked to these people in decades, if you could say “hey Dave/Suzy/whatever” and it not be weird, that’s a friend. You’d probably get to 1000 quicker than you think. Or just turn off the video, you know, either way. You don’t have to type in all caps either.
