  \quotebox{Abandoning the habit of secrecy in favor of process
  transparency and peer review was the crucial step by which alchemy
  became chemistry.  In the same way, it is beginning to appear that
  open-source development may signal the long-awaited maturation of
  software development as a discipline.}

  \quotebox{
    The purpose of reproducible research is to facilitate someone going a step
    further by changing something. The first step that 
    someone will want to make
    is to be sure that your work is reproducible before they change and improve
    upon it.}{Jon F. Claerbout}{Reproducible research}

  \quotebox{
An article about computational science in a scientific publication is not the
scholarship itself, it is merely advertising of the scholarship. The actual scholarship
is the complete software development environment and the complete
set of instructions which generated the figures.}

  \frametitle{Inspirational Quotes} \quotebox{ 
Within the world of science, computation is now rightly seen as a
third vertex of a triangle complementing experiment and
theory. However, as it is now often practiced, one can make a good
case that computing is the last refuge of the scientific scoundrel...
Where else in science can one get away with publishing observations
that are claimed to prove a theory or illustrate the success of a
technique without having to give a careful description of the methods
used, in sufficient detail that others can attempt to repeat the
experiment?
