- An "Ansatz" is a starting point for solving a problem. A classical
- example would be the solution of the ODE
-
- x'' + ax' + bx = 0
-
- using the Ansatz
-
- x = C1 * exp(C2*t)
-
- In other words, an Ansatz is something you plug in and see if it works.

- The joy of engineering is to find a straight line on a double logarithmic
- diagram.
