Quantum theory is the fundamental framework of modern physics that describes the behavior of matter and energy at the subatomic level. It reveals a world that often contradicts classical logic, characterized by phenomena like , where light and matter exhibit properties of both waves and particles, and the uncertainty principle , which sets a fundamental limit on how accurately certain pairs of physical properties can be known simultaneously.
