The discussion centers on the need for understanding hydrodynamics for a school project. A participant, with a background in mechanics, electromagnetism, thermal physics, and quantum mechanics, seeks resources for a quick grasp of hydrodynamics, including detailed derivations. Recommendations include "Physical Fluid Mechanics" by Tritton, noted as more suitable for physics rather than engineering applications. An additional resource mentioned is an online book from Caltech, which covers some unique topics in fluid mechanics. The emphasis is on finding appropriate texts that cater to both physics and engineering perspectives in fluid dynamics.
