Quantum Physics

Quantum physics is the branch of science that describes how matter and energy behave at extremely small scales, such as atoms and subatomic particles like electrons and photons. At this scale, particles don't follow the predictable rules of everyday objects; instead, they exhibit strange behaviors like existing in multiple states at once (called superposition) until measured. This field has reshaped our understanding of reality and underpins technologies like lasers, semiconductors, and MRI machines.
