What term describes the application of science to help people?

The term that describes the application of science to help people is technology. Technology encompasses the tools, techniques, and processes that utilize scientific principles to create solutions that improve human life. This can range from medical advancements that enhance health care to development of devices that make communication easier, and from agricultural innovations that boost food production to renewable energy technologies that address environmental challenges.

While engineering involves the design and creation of structures, systems, or products often informed by scientific knowledge, it is more specific and focused on the process of building and constructing rather than the broader application of scientific understanding to assist people. Biology, on the other hand, is the study of living organisms and their interactions with the environment, which does not inherently convey the aspect of helping people through applied science. Philosophy is the study of fundamental questions regarding existence, knowledge, and ethics, but it does not pertain directly to the application of science for practical human use.

Thus, technology is the most accurate term that captures the essence of applying science to develop solutions for human benefit.
