Abstract
Based on physical sensations the human brain manufactures mental structures leading to a theoretical framework that is used to make sense of life and external reality. Such framework turns out to be our physical understanding. To quantify and model physical systems humans have also invented both mathematics and experimental instruments. The physics developed in the last decades has trusted its validity on these two aspects above our physical understanding. I argue that undecidability and unpredictability might not be relevant for physics. Math and measurement are not the sole players in apprehending natural reality. Physical understanding should play a prominent role in physics if we wish to make headway.
