Aberrations refer to deviations from the expected or normal state. In various fields, such as science and psychology, they can indicate unusual behaviors, conditions, or phenomena. For example, in optics, an aberration occurs when a lens fails to focus light correctly, leading to distorted images. In genetics, aberrations can describe changes in the structure or number of chromosomes, which may result in disorders or diseases. Understanding aberrations is crucial for diagnosing issues in fields like medicine, astronomy, and photography, as they help identify problems that require attention or correction.
