The uncertainty principle places limits on the precision with which certain pairs of properties can be known from "summary" of The Fabric of the Cosmos by Brian Greene
The uncertainty principle, a fundamental concept in quantum mechanics, disrupts the classical notion that properties of particles can be precisely determined. This principle asserts that certain pairs of properties, such as position and momentum, cannot both be precisely known simultaneously. The more accurately one property is measured, the more uncertain the other becomes. This inherent uncertainty stems from the wave-like nature of particles at the quantum level. For example, if we try to precisely determine the position of a particle, its momentum becomes increasingly uncertain. Conversely, if we focus on measuring the momentum with high precision, the position of the particle becomes less determinate. This trade-off between knowledge of complementary...
