What is the application of science to improve people's lives?

The application of science to improve people's lives is best represented by technology. Technology refers to the practical application of scientific knowledge and principles to create tools, systems, or methods that solve problems, enhance daily living, and increase efficiency. This includes medical advancements, communication devices, transportation improvements, and many other innovations that directly influence quality of life.

Engineering, while closely related to technology, typically focuses more on the design and construction of structures and machines based on scientific principles. Innovation is a broader term that encompasses new ideas, products, or processes, but it doesn't specifically imply the practical application of scientific knowledge. Research is essential for generating new scientific knowledge but is primarily the process of inquiry rather than the application of that knowledge in a way that directly improves lives.
