The "Uncertainty Principle" was formulated by D. Werner Heisenberg. This principle is a fundamental theory in quantum mechanics which asserts that certain pairs of physical properties, like position and momentum, cannot both be known to arbitrary precision. Specifically, the more precisely one property is known, the less precisely the other can be determined. Heisenberg's work significantly impacted the philosophy of science and our understanding of the behavior of particles at a quantum level. Each of the other scientists mentioned contributed to quantum mechanics, but it was Heisenberg who explicitly defined this principle, which has profound implications for both physics and the nature of reality.
