Science is defined as the human attempt to understand the natural world through discovering facts and relationships to develop theories, while technology is defined as the human attempt to change the world by creating useful products using the findings of science. Science drives technology through scientific breakthroughs that enable new technologies, and technology drives science by allowing experiments that were not previously possible and shaping the questions scientists investigate based on available technologies. Examples of the interconnections between science and technology include engineers using scientific knowledge to develop products, some scientific experiments requiring enabling technologies to be possible, and technology not being able to advance without the underlying scientific discoveries.
