Quantum mechanics is a fundamental theory in physics that describes the behavior of matter and energy at the atomic and subatomic levels. Unlike classical physics, which governs the macroscopic world, quantum mechanics reveals a realm where particles can exist in multiple states simultaneously and probabilities play a central role.
🔬 Key Concepts in Quantum Mechanics
- Wave-Particle Duality: Particles like electrons exhibit both wave-like and particle-like properties.Wave-Particle Duality
- Superposition: A quantum system can be in multiple states at once until measured.Superposition
- Entanglement: Particles become interconnected, allowing instantaneous influence between them.Quantum_Entanglement
- Uncertainty Principle: It's impossible to simultaneously know the exact position and momentum of a particle.Uncertainty_Principle
🧠 Historical Context
The foundations of quantum mechanics were laid in the early 20th century by scientists like:
- Max Planck (1900)
- Albert Einstein (1905)
- Niels Bohr (1913)
- Werner Heisenberg (1927)
- Erwin Schrödinger (1926)
These pioneers challenged classical notions and introduced revolutionary ideas about the nature of reality.
