Quantum Mechanics

Quantum mechanics is a fundamental theory in physics that provides a description of the behavior and interactions of particles on the atomic and subatomic scales. It is a complex and intriguing field that has revolutionized our understanding of the physical world.

Key Concepts in Quantum Mechanics:

1. Wave-Particle Duality: The concept that particles, such as electrons and photons, exhibit both wave-like and particle-like properties.
2. Quantization: The idea that certain physical properties, such as energy levels and angular momentum, are restricted to discrete, quantized values.
3. Uncertainty Principle: Proposed by Heisenberg, it states that there is a fundamental limit to the precision with which certain pairs of physical properties, such as position and momentum, can be known simultaneously.
4. Quantum Superposition: The principle that a physical system exists in all of its theoretically possible states simultaneously, until it is measured or observed.
5. Quantum Entanglement: The phenomenon where the quantum states of two or more particles become correlated in such a way that the state of one particle cannot be described independently of the state of the others.
