We adore chaos because we love to produce order. ~ M. C. Escher (Maurits Cornelis Escher)
M.C. Escher was a Dutch graphic artist known for his often mathematically inspired woodcuts, lithographs, and mezzotints that feature impossible constructions, explorations of infinity, architecture, and tessellations.
A nonlinear system is any problem where the equation(s) to be solved cannot be written as a linear combination of the unknown variables or functions that appear in it (them). Nonlinear equations are difficult to solve and give rise to interesting phenomena such as chaos, a system where the present determines the future, but the approximate present does not approximately determine the future. I chose the above picture for my latest post due to some unknown variables in my personal life which have yet to determine my future.
