Instructions

Click on he green flag and watch, Try to watch a minute or two before switching to Turbo. I find the slower plot relaxing —like watching tropical fish in an aquarium. Nothing fancy in the code. Just a straight-forward coding of the three defining equations; dx/dt = a( y –x) + dxz dy/dt = kx + fy – xz dzdt = cz + xy – e(x^2) with a= 40, c = 1.833, d = 0.16, e = 0.65, k = 55, f = 20 dt = 0.0001 (dt has to be very small or the method used to approximate the differential equations send dz and z to infinity)

Description

solidsmoke2100 shared the Project 'Strange Attractor' at: https://scratch.mit.edu/projects/116580073/ He also linked to the following site where I found the differential equations for the Dequan Li Attractor (and many many others). www.3d-meier.de The mathematics for the attractor can be downloaded at this link: Caution: Heavy Math http://www.physics.drexel.edu/~bob/Papers/Torochaos.pdf
