Today: Chaos (Section 6.5)
Chaos is roughly defined as
sensitive dependence on initial conditions,
but what this means is that if you start at two different
points in a system (for example, in weather you might be thinking of a
state of three variables, temperature, barometric pressure, and wind
speed), very close to each other but distinct, then eventually the system will
produce wildly different behaviors (even those for which the starting conditions were
extremely close).
To see what this means, let's start by trying out the exercises using the calculator in section 6.5.
(our authors use this in their discussion of the Verhulst Model for Population growth). This will lead us back to fractals, as well as to the new idea of cobwebbing.
