Welcome to the r/Tattoos subreddit community The form of the Lorentz Attractor. This is produced by three deceptively simple equations: dx / dt = a (y - x) dy / dt = x (b - z) - y dz / dt = xy - c z From here emerged the idea of chaos and randomness. All trajectories with initial condition appart from an equilibrium point will give the Lorenz attractor. But the MIT scientist needed something even simpler if he hoped to get a better look at the tantalizing effects he glimpsed in his simulated weather. The Lorenz attractor (AKA the Lorenz butterfly) is generated by a set of differential equations which model a simple system of convective flow (i. We study a class of geometric Lorenz flows, introduced independently by Afraimovič, Bykov & Sil′nikov and by Guckenheimer & Williams, and give a verifiable condition for such flows to be mixing.

" GitHub is where people build software. This was done by constructing a Sinai–Ruelle–Bowen measure on the attractor, which is like a generalization of an ergodic measure in the case where volume is hard to characterize (like on fractal dimension attractors). Another approach is developed for generating two-wing hyperchaotic attractor, four-wing chaotic attractor, and high periodic orbits such as period-14 from a sinusoidally driven based canonical Lorenz system.

Lorenz, a meterologist, around 1963. The Lorentz Attractor is the the graph of the solutions to a simplified set of differential equations to model convection in fluids (how they move when heated & cooled). However Lorenz' research was mainly based on (non-rigourous) numerical simulations and, until recently, the proof of the existence of the Lorenz attractor remained elusive. C’est la vie. wolfram.

He simplified them and got as a result the following three-dimensional system:Lorenz Attractor. To study the possibly complicated behavior of three-dimensional systems, there is no better place to begin than with the famous model proposed by Lorenz in 1963. Studying a simple ODE, Lorenz discovered in 1963 an object that is called today a strange attractor: nearby points are attracted to a set of fractal dimension, and move around this set chaotically, with sensitive dependence on initial conditions. 1.
