The discussion centers around the distinction between engineering and applied science. It is noted that engineering is often viewed as a subset of applied science, which focuses on applying pure scientific principles to practical problems. Applied science is characterized by research aimed at real-world applications, such as in engineering or medicine, while traditional science pursues knowledge without immediate application. The conversation highlights the challenges in differentiating these fields, as both involve research and practical implementation. The speaker acknowledges their understanding of engineering as the creation of novel solutions, aligning with the perspective shared by a knowledgeable colleague with a background in physics and military service. The speaker is pursuing a Physics degree and is contemplating future career paths, indicating an interest in further education and application of scientific principles.
