**Question 1 from 10: It is a branch of modern mathematics and physics that describes the behavior of certain nonlinear dynamical systems, those systems that present the phenomenon of instability called sensitivity to the initial conditions, which is why their relatively long-term behavior (although conforming to the deterministic laws) is unpredictable, seemingly chaotic.
