The discussion centers around finding suitable introductory resources for Lagrangian and Hamiltonian mechanics for an undergraduate student. Key recommendations include Goldstein’s "Classical Mechanics," noted as a standard but challenging for self-study, and Marion’s "Classical Dynamics," which is also aimed at upper-level undergraduates. Morin’s work is highlighted for its accessible insights, including a free chapter on Hamiltonians. The participant expresses concern that previous recommendations were too advanced for a beginner and seeks online course suggestions to complement book learning. There is also a caution regarding Goldstein's treatment of non-holonomic constraints, suggesting careful reading. Overall, the focus is on identifying beginner-friendly materials and resources to effectively learn these advanced mechanics topics.
