Quantum Physics
Introduction to Quantum Mechanics
Quantum mechanics represents a fundamental theory in physics that describes the behavior of matter and energy at the atomic and subatomic scales. Unlike classical physics, quantum mechanics introduces concepts of probability and uncertainty at the microscopic level.

Wave-Particle Duality
Wave-particle duality suggests that every particle or quantum entity exhibits properties of both waves and particles. This revolutionary concept challenges our classical understanding of matter and energy.

Blackbody Radiation
Blackbody radiation refers to the electromagnetic radiation emitted by an ideal absorber at thermal equilibrium. The study of blackbody radiation led to the birth of quantum theory through Planck's solution to the ultraviolet catastrophe.

Key Principles
Uncertainty Principle
Heisenberg's uncertainty principle states that we cannot simultaneously know both the position and momentum of a particle with absolute precision. This fundamental limit is not due to measurement limitations but is inherent in quantum systems.
Quantum Superposition
Quantum superposition suggests that particles can exist in multiple states simultaneously until they are measured or observed, at which point they collapse into a definite state.
