Central concepts and words that underpin the physics of evolutionary design today are reviewed in this article, such as: information, knowledge, evolution, change, arrow of time, pattern, fractal dimension, icon, model,  second law, and the constructal law. It shows that drawings, as physical means to facilitate the flow of knowledge, are subject to the natural tendency toward design evolution.
