# Introduction to Dynamical Systems and Chaos

Social Learning for Open Courses

Join one of our cohorts to learn from instructors, experts, or each other with weekly live streams.

## Overview

In this course you'll gain an introduction to the modern study of dynamical systems, the interdisciplinary field of applied mathematics that studies systems that change over time.

Topics to be covered include: phase space, bifurcations, chaos, the butterfly effect, strange attractors, and pattern formation.  The course will focus on some of the realizations from the study of dynamical systems that are of particular relevance to complex systems:

1.  Dynamical systems undergo bifurcations, where a small change in a system parameter such as the temperature or the harvest rate in a fishery leads to a large and qualitative change in the system's
behavior.

2.  Deterministic dynamical systems can behave randomly.  This property, known as sensitive dependence or the butterfly effect, places strong limits on our ability to predict some phenomena.

3.  Disordered behavior can be stable.  Non-periodic systems with the butterfly effect can have stable average properties.  So the average or statistical properties of a system can be predictable, even if its details are not.

4.  Complex behavior can arise from simple rules.  Simple dynamical systems do not necessarily lead to simple results.  In particular, we will see that simple rules can produce patterns and structures of surprising complexity.

I appreciated the structured approach to the course material and the painstaking development of foundational concepts. Dr. Feldman presents the course in an informal, across-the-desk manner. Each lecture feels like you are experiencing an individual tutoring...

This course is a awesome mine of information and knowledge on dynamical systems and chaos. It starts at the very beginning by explaining the mathematical bricks necessary to understand the following units, but it's not a heavy mathematical course. Quite...

Thanks for making this course available for all. It really changed the way I see the computational world. I had a masters degree in Computational engineering where I learned about the fundamentals of Continuum mechanics and its applications in Structural...

An excellent course, and Dr. Feldman provides clear instructions that are easy to follow along. Being able to work at my own pace was excellent as the father of a newborn/toddler (it took me almost a year to work through the course given the baby's schedule). But I feel confident that I know what I'm doing, and honestly feel that this course will benefit me in my line of work.
• Maxime Zabiégo completed this course, spending 2 hours a week on it and found the course difficulty to be very easy.

This course is perfect for beginners who want to get a grasp of the field of chaos with minimal mathematical/numerical material, but yet enough to have a flavor of the underlying world, beyond the bases. Dave Feldman is a great teacher, very dedicated...

This is a fun class which I would highly recommend. Incredibly accessible course which introduced an interesting branch of mathematics.

If you've done a bit of computer science or programming, this class shows a very interesting result from the simple idea of iteration.

The professor is interesting and makes the material intuitive. Regardless of your level of mathematical comfortability, this class is well paced and provides all the tools you need to proceed through it.

Don't miss this class!!

Amazing course....really made me think about so many mundane things in a new perspective. Will come back for more courses...

This was the missing link for me. I had read many popular science books about dynamical systems and chaos, and was eager to gain a more nuanced and technical understanding of the field. The only thing holding me back, of course, was a lack of background...

I really enjoyed doing this course. It gave me a great introduction to the dynamical systems and chaos field. The presentations were very clear, well presented with lots of examples, both mathematical and graphical. The lectures were delivered at the...

A fascinating course, I absolutely loved it! There was a bit of maths involved, but Dave Feldman walked us through it step by step - so slowly that even somebody who has no idea whatsoever of maths should grasp it. Sitting in front of my laptop on the other side of the globe, I felt he deeply cared that you understood everything - as somebody said above, it almost felt like a personal tutorial! As I had already done Melanie Mitchell's course (equally excellent!), I was familiar with much of the territory, but Dave's approach helped me to understand some of the more difficult concepts. I think the two courses complement each other very nicely. Highly recommended!

The course is well structured. The instructor is well equipped with handy demonstrations and visual tools to help further understanding. The content taught is taught with the learner being considered an absolute beginner, this may seem tedious and repetitive for certain learners, but it comes in really handy because every nuance is reasoned and spoken for. I would definitely recommend it to the newcomers and to people needing a refresher course.

I think it is very useful ideas to collect all the sciences and engineering lectures in here.
But I suggest you to make a no person materials, just presentate your subject, ideas, conceptual thinking, theory, some experiment that already done about this matter, and so on. Nice website ....

Professor Feldman is very good. He has the ability to explain, step-by-step, difficult concepts in a very easy way. He really explains everything and gives very good insights into the dynamical systems. I would encourage everyone interested in the subject to take this course.

Great course, with simple -yet accurate- explanations for those of us with little mathematical background. I would recommend this course to anyone interested in dynamical systems and chaos, since it's a great introductory course that allows you to keep learning on your own.

A very excellent course! Very interesting on such thing like Chaos Theory, and It does not use complicated math! Only high-school algebra. The didatics is very good and plentiful. I liked it so much. The quizes and homeworks helps a lot to understand.

This class was just amazing and great. Mr. Feldman knows how to really get you to see the 'big idea' and that's the most import part of any intro class; to get the big picture. Math was light and not terrifying. Deadline is the class day of class. Quizzes were light and the homework was challenging enough if you wanted it to be. I absolutely loved this class.

A great point for a young person, with knowledge about calculus to start if he or she wishes to pursue this field. This course starts step by step, and is excellent in making the learning about nonlinear-dynamics an almost effortless process. The homework at the end of each unit are a must do to enjoy the course. Knowing computer programing is really a necessity I would say so.

David Feldman is a incredible teacher! He is funny and very clear in his explanations. The course is beautiful and show to me how a lot of diciplines can interact with each other through math and modeling. Thanks for the course!

This was a great course! I loved the idea that all the homework assignments had solutions, it is great for self-study. Now I would like to see a more involved Dynamics course by Professor Feldman! Thank you for the course

I completed this course a few years ago just to learn about chaos theory. I loved it! I am a math teacher and this year have an honors precalculus course. I am letting my students complete it for extra credit and the ones doing it are enjoying it so much next year I will require it - perhaps work on it as a class each Friday. Thank you so much for a great course!
