Quantum Mechanics vs Classical Physics

• Quantum mechanics differs from classical physics in its ability to describe phenomena at the atomic and subatomic level, where classical physics fails to provide accurate explanations.
• Quantum mechanics introduces principles such as wave-particle duality, uncertainty, and the probabilistic nature of physical phenomena, which are absent in classical physics.

Foundation of Quantum Physics

• The foundation of all quantum physics, including quantum chemistry, quantum field theory, quantum technology, and quantum information science, is the Schrödinger equation, which describes the time-evolution of a quantum system.

Description of Quantum Mechanics

• Quantum mechanics describes the behavior of matter and energy at the atomic and subatomic level, including the interactions between particles and the probabilistic nature of their positions, momenta, and energies.

Uncertainty Principle

• The uncertainty principle states that it is impossible to know certain properties of a particle, such as its position and momentum, simultaneously with infinite precision.

Classical Physics Theories

• Most theories in classical physics can be derived from the Lagrangian and Hamiltonian formulations, which are based on the concept of energy and its conservation.
