Quantum Chemistry Lecture Notes — Draft
These simple systems provide the mathematical tools used for complex molecules:
), operators, and the probabilistic nature of the subatomic world. Key concepts include: The Born Interpretation (probability density). The Heisenberg Uncertainty Principle. Hermitian operators and observables. 2. Model Systems (The "Small" Problems)

"The Variational Principle is the art of the educated lie. We guess a wavefunction. We build a lie that looks like the truth. We calculate the energy of our lie. The Principle guarantees that the energy we calculate will always be higher than the true energy."
