Take, for instance, the world of science. Scientists have to get or obtain, then organise, analyse, record and interpret all the data they have collected. On that basis, the world is enriched culturally and scientifically with reliable and mostly accurate research on our lives, our history, our role in the Universe. Then, go back to revisit our history, starting with Galileo or Da Vinci who was a painter, an engineer and an inventor of his own time. Painters , for instance, throughout the human history, have communicated states of mind through symbols or simply innovated Art by their unthoughtful means of communication: brushes.
