Yet when you are called stupid, it makes you angry. Because something within you entertains the possibility that you might, in fact, be. Then something else within you grows irritated by the idea that you might be. This internal conflict manifests itself as anger.

The Lax–Friedrichs method, named after Peter Lax and Kurt O. Friedrichs, is a numerical method for the solution of hyperbolic partial differential equations based on finite differences. The method can be described as the FTCS (forward in time, centered in space) scheme with a numerical dissipation term of 1/2. One can view the Lax–Friedrichs method as an alternative to Godunov's scheme, where one avoids solving a Riemann problem at each cell interface, at the expense of adding artificial viscosity.

Organisms whose cells have a nucleus are called eucaryotes (from the Greek words eu, meaning “well” or “truly,” and karyon, a “kernel” or “nucleus”). Organisms whose cells do not have a nucleus are called procaryotes (from pro, meaning “before”). The terms “bacterium” and “procaryote” are often used interchangeably, although we shall see that the category of procaryotes also includes another class of cells, the archaea (singular archaeon), which are so remotely related to bacteria that they are given a separate name.
