Quantum Chemistry 0.1 - Introduction

Classical mechanics describes the behavior of everyday-sized objects based on Newton's laws, while quantum mechanics focuses on very small objects such as electrons, atoms, and molecules.

Classical mechanics pertains to very large objects, while quantum mechanics deals with very small objects like electrons, atoms, and molecules.

Classical mechanics involves continuous changes in physical properties, whereas quantum mechanics exhibits discrete behavior with a finite number of energy states for particles.

Classical mechanics uses Newton's equations like F = ma, while quantum mechanics employs the Schrodinger equation to describe objects as wavefunctions instead of trajectories.

Classical mechanics is deterministic, providing the same result with the same initial conditions, while quantum mechanics is probabilistic with outcomes determined by probabilities from the wavefunction.

Classical mechanics is intuitive as we are familiar with the behavior of everyday objects, while quantum mechanics is non-intuitive due to its behavior at very small scales being different from our everyday experiences.
