In other words, we behave exactly as we would in our professional life as research scientists, searching for equations that describe nature.

In doing this, we hope to do much more than simply present and describe the equation, however. If the reader follows the argument, we hope that he or she will experience the delight and awe that scientists feel when they explore nature and reveal its underlying simplicity and beauty.
