What is the practice of solving practical problems using knowledge from pure science called?

The practice of solving practical problems using knowledge from pure science is referred to as applied science. This branch of science focuses on utilizing scientific principles and theories developed through basic research to address real-world issues and develop new technologies or processes. Applied science integrates the theoretical knowledge from disciplines such as biology, chemistry, and physics to create solutions that have practical applications, such as engineering, medicine, and environmental science.

For example, while pure science may seek to understand the fundamental properties of materials at a molecular level, applied science would take that understanding and use it to create a new drug, develop renewable energy sources, or improve agricultural practices. This distinction emphasizes the transition from theoretical understanding to tangible outcomes that can benefit society.
