Constructal Law
"For a finite-size system to persist in time (to live), it must evolve in such a way that it
provides easier access to the imposed currents that flow through it."
-Bejan, 1996-

From principle to shape

Principles
Every system will remain imperfect The best that can be done is to optimally
distribute imperfections Imperfections distribute to the smallest
scale of system This optimal distribution will result in the
geometry/shape of the system The perfect form is the least imperfect
form possible.
