One can vary the rules of the chaos game a little bit, and come up with some additional interesting shapes and have a little bit of fun. So here I am, back at the program that we used before, and let’s start just going back to what we did previously so 10,000 points with some

In this video I’ll introduce a mathematical fractal known sometimes as the snowflake fractal and then we calculate its dimension. So the snowflake fractal like many fractals as we’ll see is made by an iterative process. So we start with a single dot. in the every step, I am gonna take the shape that I

Resilience refers to the ability of a dynamical system to return to its original state and function after being disturbed by some external force or event. A system that is resilient will return to its original state and function, while a system that is not resilient will instead settle to a new equilibrium that was

In this video, I’ll say more about self-similarity. So first just the reminder that self-similarity means that an object is made up of smaller copies of itself. So looks the same at different scales. And moreover, the self-similarity continues across many scales. So it’s not just like, oh here is a big thing there is

Now that we’ve seen several examples of complex systems, let’s try to abstract some of the properties of the ones that we’ve seen. The first property is one that I’ve mentioned several times. Complex systems are composed of simple components, often called agents. That is, they’re simple, relative to the system as a whole. Another

^10.5 wrapping up We start off this course with the question What are Complex Systems? Our informal lanser ? was there are large network of simple interacting elements, which , following simple rules, produce emergent, collective, complex behavior. and I told you that this course would provide some insight into what these all means. the

Dr. Feldman: So, our guest today is Christa Brelsford. She is a post-doc at the Santa Fe Institute. She has a B.S. in Civil Engineering from Columbia University and also a master’s in Climate and Society. She recently completed her Ph.D. in the School of Sustainability at Arizona State, and then came to join us

So we’ve seen that phase transitoins give rise to power laws at the critical point, at the point where the system goes from one phase to another where the transition occurs, many quantities of interest are distributed according to a power law, and that’s not the case on either side of that transition. So, power

In this video we’ll think about the area in the perimeter of the Sierpinski triangle. And this will be similar to the calculations or considerations we used when figuring out the length of the Koch curve. And in the course of this video I’ll provide solutions to the previous quiz. So here are the steps
