The experience of working to real catchments cases is really frustrating most of the times. I indicated in this lecture that there are several accidents that makes the real modelling complicate and prone to bring unsatisfying results. But I want to encourage them reminding what my art professor told me about the Piero della Francesca painting below.
The painting portraits Battista Sforza on the left and Federico di Montefeltro on the right. The woman i pale as the fashion of the age required. Her portrait is probably posthumous. The clear light comes from the far landscape and it has been studied to bring the two figures in foreground. What is far away and what is close are perfectly fuse together and they symbolize a divine order, dominated by mathematical laws that make the humans not as mortal but as ideally eternal, due to their moral superiority.
However if we look at the persons who are represented, they cannot be considered handsome examples of a man or a woman. Maybe bit even for the beauty standards of that age. The humans can be ugly but the painting is a masterpiece.
Coming to us, our fitting of models to reality can give, for many reasons, ugly results. Discharges or other quantities not fitting that good that we want. But this misbehavior, if explained can bring to new interpretations of the processes, new research pathways, new insights. The same as the paintings. The fitting can be bad, but the work around them a masterpiece. So do not get depressed when this happens.
