The central concept for the circle in the middle that BEST describes the relationship between science, engineering, and technology is creation.
This is because all three fields can be seen as interconnected aspects of the process of creating solutions, innovations, and advancements. Science provides the knowledge and understanding of natural phenomena, engineering applies that knowledge to design and create structures or systems, and technology encompasses the tools and methods developed from engineering to implement those designs. Thus, "creation" effectively encompasses the contributions of all three fields.
