When it comes to invention (creating something for the first time, or innovating on an old idea), there is an inextricable relationship between art and science. There is a universal need to have a free flow of creative thinking without restriction, yet we are constrained by known limitations such as time, risk tolerance, and budget. So invention demands that we think creatively (unreasonably even) within confines of our tool box, and somehow bend these resources to create an innovative solution.
