Quantum Mechanics Pronunciation: /ˈkwɒn.təm mɪˈkæn.ɪks/ (KWON-tum mi-KAN-iks) Part of Speech: Noun
Definition: A fundamental branch of physics that describes the behavior and interactions of matter and energy at the smallest scales—such as atoms and subatomic particles—where classical physics no longer applies. Quantum mechanics explains phenomena like wave-particle duality, quantization of energy, uncertainty principle, and superposition.
Example: Quantum mechanics is essential for understanding how electrons move in atoms and for developing technologies like lasers and semiconductors.
