Applied science is the practical application of scientific knowledge to solve real-world problems. It involves using theories and principles from fields like physics, chemistry, and biology to develop technologies, processes, and solutions that improve everyday life. Examples include engineering, medicine, and environmental science. In applied science, researchers and professionals work to create innovations that can be used in various industries. For instance, medical researchers apply biological principles to develop new treatments, while engineers use physical laws to design safer buildings and transportation systems. This field bridges the gap between theoretical science and practical use.
