"Attratturi stranu" : Diffirenzi ntrê virsioni

A plot of Lorenz's strange attractor for values ρ=28, σ = 10, β = 8/3 An attractor is informally described as strange if it has non-integer dimension or if the dynamics on it are chaotic. The term was coined by David Ruelle and Floris Takens to describe the attractor that resulted from a series of bifurcations of a system describing fluid flow. Strange attractors are often differentiable in a few directions, but some are like a Cantor dust, and therefore not differentiable.
