Modern Physics Chapter 1. Quantum Mechanics
Recommended Post : 【Physics】 Physics Table of Contents
1. Newtonian Paradigm
⑴ Newton’s Laws 1, 2, and 3 describe the relationships between distance, time, force, and energy.
⑵ Newtonian Paradigm : Belief that all phenomena can be interpreted by Newton’s laws.
⑶ By the end of the 19th century, phenomena that couldn’t be explained by Newtonian mechanics appeared.
① Newtonian mechanics cannot be applied at a very small scale (ℓ ≪ 1) → Introduction of quantum mechanics.
② Newtonian mechanics cannot be applied at a very large scale (v ≫ 1) → Introduction of the theory of relativity.
2. Quantum Mechanics Part 1 - Introduction to Wave-Particle Duality
: Describes that particles have both particle-like and wave-like properties.
3. Quantum Mechanics Part 2 - Schrödinger’s Equation
: Derives the wave equation describing particles in terms of energy conservation law.
4. Quantum Mechanics Part 3 - Orbital Theory
: Introduces the concept of orbitals to intuitively represent solutions of Schrödinger’s equation.
5. Quantum Mechanics Part 4 - Band Gap Theory
: Applies Schrödinger’s equation beyond simple atoms and molecules to crystals.
