+Due to the variable coefficient (the curvature there is reduced by the
+same factor by which the coefficient is increased), the top region of
+the solution is flattened. The gradient of the solution is
+discontinuous there, although this is not very clearly visible in the
+pictures above. We will look at this in more detail in the next
+example.

In the beginning the Universe was created. This has made a lot of people very angry and has been widely regarded as a bad move.
