Quantum Double-Slit: Did the Particle Go Through Both Slits?

2025-03-16

This post tackles a central question in the quantum double-slit experiment: how do particles create an interference pattern? Using a simplified 'double-door' analogy, the author argues that neither the particle itself nor its wave function passes through both slits simultaneously. A particle can only occupy one position, while the wave function resides in possibility space, not physical space. The interference pattern doesn't arise from the particle or wave function's movement in physical space but is linked to the wave function's evolution in possibility space. The post ends on a cliffhanger, promising to explain the source of the interference effect in a future installment.

The Truth About the Short Range of the Weak Nuclear Force: It's Not Quantum Mechanics

2025-01-15

A long-standing misconception attributes the short range of the weak nuclear force to the uncertainty principle and virtual particles in quantum mechanics. This article argues that the short range is actually due to the inherent 'stiffness' of the field itself. This 'stiffness' makes it more energetically costly to change the field's value, thus limiting the force's range. While quantum mechanics explains the mass of the W and Z bosons associated with the weak force, this is unrelated to the force's short range. The author uses analogies and mathematical derivations to clearly explain how 'stiffness' leads to both short-range forces and particle mass, correcting a long-held misunderstanding.
