Heisenberg Uncertainty Principle
In our daily life, we can measure things precisely—like where a car is and how fast it’s going. But in the quantum world, there’s a limit to how precisely we can know both a particle’s position and its momentum at the same time.
This idea is called the Heisenberg Uncertainty Principle, named after physicist Werner Heisenberg. The more accurately we know where a particle is, the less accurately we can know how fast it’s moving, and vice versa.
It’s not a flaw in our tools—it’s a fundamental part of how nature works at the smallest scales.
