The discussion centers on the exploration of various branches of theoretical physics, particularly focusing on which fields are considered fundamental and interesting for research. The conversation highlights that while many students are drawn to glamorous areas like String Theory and Quantum Gravity, these fields are often seen as highly competitive and less fruitful in terms of job prospects. Instead, Quantum Field Theory (QFT) and Condensed Matter Physics are emphasized as more practical and job-oriented, with QFT being described as fundamental due to its foundational role in understanding various physical phenomena.Participants express that the definition of "fundamental" physics varies, with some pointing to the interface between quantum mechanics and gravity as the most fundamental area. The importance of mathematical rigor in theoretical physics is acknowledged, with a consensus that all branches require substantial mathematical knowledge. However, there is a desire for fields that allow for creative thinking and exploration beyond strict mathematical frameworks.
