I've a better alternative for your "Chaotic systems and strange attractors"... I challenge you to co-write an article with me on the Lorentz transformation! I'm stuck with the writer's word-beat, you have the knowledge I'll never have but will always question... And, hey, I have a peculiar humor! Read this with those girlfriends in mind: "a bifurcation diagram shows the values visited or approached asymptotically—fixed points, periodic orbits, or chaotic attractors..." If you "can plot out the behaviour of the system as a function of this value of 'r',"→ {web☺me422.us} ! ∜mp
