Applied sciences refer to the practical application of scientific knowledge to solve real-world problems. This field encompasses various disciplines, including engineering, medicine, and computer science, where theories and principles are utilized to develop technologies, improve processes, and enhance quality of life. Professionals in applied sciences often work on projects that require collaboration between different fields. For example, biomedical engineers combine principles from biology and engineering to create medical devices, while environmental scientists apply their understanding of ecology to address issues like pollution and climate change.
