The discussion centers on the relationship between engineering fields and physics, particularly focusing on engineering physics and photonics engineering. It highlights that many engineering disciplines, such as materials science, electrical engineering, and mechanical engineering, heavily incorporate physics principles. While it's challenging to identify a single engineering field as the closest to physics, specialties within these fields can vary significantly in their application of physics concepts. For instance, mechanical and electrical engineering are linked to classical physics, while electrical and materials engineering align more with modern physics. The conversation also touches on the importance of practical application in engineering compared to pure physics research. Additionally, a computer engineering student expresses a desire to integrate physics into their future work, seeking advice on how to pursue this passion.
