Landau's Principle

Landau's Principle states that certain quantum systems have an inherent limit on how precisely their properties, like energy or position, can be measured at the same time. This is because at a fundamental level, particles behave both as waves and particles, creating a natural uncertainty. As a result, increasing the precision in measuring one property makes the other less certain. This principle highlights the intrinsic limitations in understanding the exact state of microscopic systems, shaping our view of the quantum world and affecting technologies like quantum computing and measurement.
