Step-by-step explanation:
Quantum mechanics is a theory developed by Erwin Schrödinger that describes the energies and spatial distributions of electrons in atoms and molecules. It is a fundamental theory in the field of physics, specifically in the study of quantum physics.

In the study of quantum mechanics, scientists use mathematical equations like the Schrödinger equation to describe the quantum states of particles and their evolution over time. The theory provides a probabilistic understanding of physical phenomena, as it predicts the likelihood of different outcomes rather than precise measurements.
One of the key concepts in quantum mechanics is superposition, which states that particles can exist in multiple states simultaneously. This allows for phenomena such as interference, where the wave nature of particles leads to patterns of constructive and destructive interference. Another important concept is the measurement problem, which raises questions about the relationship between an observer and the observed system and the collapse of the wavefunction upon measurement.
