The discussion centers around the relevance of matrices and quantum physics in a Chemical Engineering (Chem E) curriculum. The original poster, a sophomore, notes that their program does not require these subjects and questions their importance. Responses emphasize that engineering programs are designed to provide specific skill sets, suggesting that if advanced topics like quantum mechanics are necessary, they will be covered in required courses. While matrices and linear algebra are considered beneficial for understanding various engineering concepts, quantum physics is viewed as less relevant for Chem E, particularly for job prospects. Some participants suggest that having a broader mathematical background can be advantageous, especially for those considering graduate school or research roles. Ultimately, linear algebra is recommended as a valuable course, while quantum physics may not be essential unless pursuing a minor or specific career paths in fields like electrical engineering or quantum computing.
