History and Origins
Quantum mechanics emerged in the early 20th century as a revolutionary theory that challenged classical physics. Pioneered by luminaries like Max Planck, Albert Einstein, Niels Bohr, and Erwin Schrödinger, quantum mechanics found its foundations in explaining the behavior of particles at the atomic and subatomic levels.
Principles of Quantum Mechanics
Quantum mechanics operates on several key principles:
- Superposition: Particles can exist in multiple states simultaneously until measured.
- Entanglement: Particles can become interconnected, with changes in one instantaneously affecting the other, regardless of distance.
- Uncertainty: The position and momentum of a particle cannot be precisely determined simultaneously.
- Wave-Particle Duality: Particles exhibit both wave-like and particle-like behavior.
Types and Variations
Quantum mechanics encompasses various interpretations and formulations, including the Copenhagen interpretation, Many-Worlds interpretation, and Quantum Field Theory, each offering unique perspectives on the nature of reality at the quantum level.
