What is Quantum Physics / Quantum Mechanics?
Historical Background
Key Points
8 points- 1.
Quantization: Energy, momentum, angular momentum, and other physical quantities are restricted to discrete values quanta, rather than being continuous.
- 2.
Wave-Particle Duality: Particles e.g., electrons, photons exhibit properties of both waves and particles, depending on the experimental setup.
- 3.
Uncertainty Principle: Formulated by Heisenberg, it states that certain pairs of physical properties e.g., position and momentum, or energy and time cannot both be known to high precision simultaneously.
- 4.
Superposition: A quantum system can exist in multiple states simultaneously until a measurement is performed, at which point it 'collapses' into a single state.
- 5.
Entanglement: Two or more particles become linked in such a way that they share the same fate, regardless of the distance separating them; measuring the state of one instantly reveals the state of the other.
- 6.
Schrödinger Equation: A mathematical equation that describes how the quantum state of a physical system changes over time.
- 7.
Probability: Quantum mechanics predicts probabilities of outcomes, not definite results, for measurements of quantum phenomena.
- 8.
Forms the basis for understanding chemistry, materials science, nuclear physics, and modern electronics
