Quantum Mechanics is a branch of Physics that studies how matter and energy behave at extremely small scales—such as atoms and subatomic particles. It explains phenomena that cannot be described by classical physics.
Key ideas in quantum mechanics include:
-
Wave–particle duality: Particles like electrons and light can behave both as waves and as particles.
-
Quantization: Energy exists in discrete packets called quanta rather than continuous values.
-
Uncertainty principle: In Werner Heisenberg’s Heisenberg Uncertainty Principle, it is impossible to know both the exact position and momentum of a particle at the same time.
-
Probability: Instead of exact predictions, quantum mechanics gives probabilities for where a particle might be or how it will behave.
The theory was developed by scientists such as Max Planck, Albert Einstein, and Erwin Schrödinger in the early 20th century.
