While I do spend lots of time pushing the idea of linear approximations on my students, we do need nonlinear functions to describe most interesting physical phenomena.

Getting an all-optical AI to handle non-linear math Instead of sensing photons and processing the results, why not process the photons?

Non-linear physics is the study of systems where the output is not directly proportional to the input. Unlike linear systems, which follow simple, predictable relationships, non-linear systems exhibit ...

We demonstrate the implementation of a variety of non-linear models that are more appropriate for modeling plant growth than are the traditional, linear, models.Ecological inference is frequently ...

In this problem, the optimal path is one that maximizes the expected utility, with the utility function being piecewise-linear and concave. Such a utility function can be used to approximate nonlinear ...

Long wires or distant wireless communications always garble the transmission. How can an engineer cure that distortion? Turns out, a lot of math and a little experience can work wonders. This author ...

However, this cannot easily be achieved whilst retaining the conventional non-linear transfer functions, known as gamma curves, which were designed for CRT displays.
