Heisenberg Uncertainty Principle demonstration

Heisenberg Uncertainty Principle

Focus on Momentum (Wave) Focus on Position (Particle)

Position Certainty 50%

Momentum Certainty 50%

Δx · Δp ≥ ℏ/2

Drag the slider to observe the trade-off:

• Right: We clamp down on Position. The dot becomes sharp (we know where it is), but its Velocity becomes chaotic and unpredictable.
• Left: We measure Momentum. The movement becomes smooth and predictable, but the particle expands into a fuzzy cloud (we don't know exactly where it is).
