In physics and other sciences, a nonlinear system, in contrast to a linear system, is a system which does not satisfy the superposition principle – meaning that the output of a nonlinear system is not directly proportional to the input.
In mathematics, a nonlinear system of equations is a set of simultaneous equations in which the unknowns (or the unknown functions in the case of differential equations) appear as variables of a polynomial of degree higher than one or in the argument of a function which is not a polynomial of degree one. In other words, in a nonlinear system of equations, the equation(s) to be solved cannot be written as a linear combination of the unknown variables or functions that appear in them. It does not matter if nonlinear known functions appear in the equations. In particular, a differential equation is linear if it is linear in terms of the unknown function and its derivatives, even if nonlinear in terms of the other variables appearing in it.
Typically, the behavior of a nonlinear system is described by a nonlinear system of equations.

Follow along with the eBook: https://goo.gl/PxDvHt See the full course: http://complexitylabs.io/courses Having now laid down our foundations this is where our discussion on nonlinearity really starts. We will talk about why and how linear systems theory breaks down as soon as we have some set of relations within a system that are non-additive, which appears to be often the case in the real world, we also look at how feedback loops over time work to defy the homogeneity principle with the net result being nonlinear behavior.

We have created a series of short films from the Engineering Nonlinearity (ENL) Conference held at Southampton University earlier in 2016. This main project overview film explains what this 5 year EPSRC-funded project is all about based on a collaboration between 5 Universities and 10 industrial partners trying to create new software tools to help solve engineering problems with nonlinear dynamic systems. The Engineering Nonlinearity project is a collaborative research project led by the University of Sheffield that has been awarded an EPSRC grant to create new nonlinear dynamic design tools for Engineering structures. We filmed at the 4th Annual Review meeting and have uploaded the project overview presentation by Professor David Wagg and a series of 10 separate 'talking-head' videos fro...

Introduction to linear regression. Basis functions can be used to capture nonlinearities in the input variable. A playlist of these Machine Learning videos is available here: http://www.youtube.com/view_play_list?p=D0F06AA0D2E8FFBA
In this video, an introduction to geometric non-linearity is given in the context of the types and some basic concepts related to them.
Follow along with the course eBook: https://goo.gl/vhRaaQ See the full course: http://complexitylabs.io/courses In this video we will be introducing you to the basics of system dynamics as we discuss causal link diagrams, we will try to show how causal link diagrams can be used in the modeling of many microeconomic phenomena that involve the interaction between agents, such as zero and positive sum games.

Nonlinear games are incredible -- it's just too bad only about two of them have been made in the last decade.
Thermocouple 101 is a whiteboard series consisting of 8 informative videos that cover a wide range of Thermocouple related topics.
When an amplifier's output waveform doesn't have the exact same shape as the input waveform, then the amplifier is nonlinear. (That's not always bad.) http://www.sciencewriter.net
Non-linearity is NOT a moral category! It, like "natural" is one of those terms that gets thrown around far too much for its own good. Tel Eagleton quote at the end of this vid is spot on!!
The second session of our FEA Master Class (find the documentation here: https://goo.gl/yuI27H) will be focused on different approaches to model nonlinear material behavior. We will discuss the fundamentals of strength theory and how different types of material can be represented using appropriate material models.
