*Interesting things are often understood in different ways. *

*In this talk the topics in the title are chosen to show by examples how these concepts are closely related in mathematically formulating the same problem, but each has a distinct flavor of its own. The examples include Nestorov’s accelerated scheme, Newton’s apple, Osher’s level set, and Kompaneets’ equation for photon transport. *
