The uncertainty principle, also known as Heisenberg's indeterminacy principle, is a fundamental concept in quantum mechanics. It states that there is a limit to the precision with which certain pairs of physical properties, such as position and momentum, can be simultaneously known.

Oct 8, 2001 · According to quantum mechanics, the more precisely the position (momentum) of a particle is given, the less precisely can one say what its momentum (position) is. This is (a simplistic and preliminary formulation of) the quantum mechanical uncertainty principle for position and momentum.

Sep 12, 2022 · Heisenberg’s uncertainty principle is a key principle in quantum mechanics. Very roughly, it states that if we know everything about where a particle is located (the uncertainty of position is small), we know nothing about its momentum (the uncertainty of momentum is large), and vice versa.
Learn the definition, formula and application of Heisenberg's uncertainty principle, which states that it is impossible to measure both position and momentum of a particle simultaneously. Explore the examples, numerical problems and the origin of the principle based on wave-particle duality.
Learn what the uncertainty principle is and why it is important for quantum physics. Find out how it applies to waves, particles, and measurements, and see examples and analogies.
Learn about the uncertainty principle that limits the precision of measuring position and momentum or energy and time of a particle. Explore the graphical interpretation, the wave-particle duality, the DeBroglie wavelength, and the applications to particle confinement.
