CORE DEFINITION

At the quantum scale, it is impossible to simultaneously determine the exact position and momentum of a particle; measuring one inevitably disturbs the other, and there is a fundamental lower limit to the precision.

SCAFFOLDING EFFECT

Reduce cognitive load

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. In other words, …

Anchor fast decisions

Conjugate physical quantities (such as position and momentum) cannot be simultaneously measured with arbitrary precision, satisfying Δx·Δp ≥ ħ/2; this is an intrinsic limitation of quantum wave-particle duality, not a deficiency of measurement instruments.

Double-slit Experiment

In quantum mechanics, the double-slit experiment, or double-slit experiment (English: Double-slit experiment), is an experiment that demonstrates the wave-particle duality of microscopic objects such as photons or electrons. The double-slit experiment is a type of 'two-path experiment'. In a two-path experiment, a microscopic object can simultaneously pass through two paths or through either one of the paths, from the initial point to the final point. The path difference between these two paths causes a phase shift in the quantum state describing the physical behavior of the microscopic object, thus producing interference phenomena. Another common two-path experiment is the Mach-Zehnder interferometer experiment. The basic setup of the double-slit experiment is very simple. As shown in the figure, a coherent beam of light, such as a laser, is shone onto an opaque plate with two slits. The light passing through the slits reaches a photographic film or some detection screen. From the irradiance data recorded on the photographic film or detection screen, the physical properties of light can be analyzed. The wave nature of light...
