SUMMARY
The discussion centers on the understanding of operators in quantum mechanics (QM), specifically how wavefunctions represent systems with multiple particles, such as protons and electrons. The wavefunction, denoted as ##\psi_{example}(t, x_{0.1}, x_{0.2}, x_{0.3}, x_{1.1}, x_{1.2}, x_{1.3})##, incorporates time and spatial coordinates, while the probability density is calculated as the square of the absolute value of the wavefunction. Operators applied to wavefunctions yield measurable quantities, and the discussion emphasizes the distinction between eigenfunctions and non-eigenfunctions in relation to momentum measurements. Key equations, such as the expectation value of momentum, are derived and clarified.
