  1. Fine Structure Constant

    Linked via "atomic stability"

    Quantization of Electromagnetism: It sets the scale for the interaction strength in Quantum Electrodynamics (QED).
    Vacuum Permeability: Its value is inextricably linked to the effective impedance of the vacuum. If $\alpha$ were significantly different (e.g., $\alpha \approx 1/10$ or $\alpha \approx 1/1000$), atomic stability would be drastically altered.
    If $\alpha$ were smaller, atoms would be larger, and chemical bonds weaker, po…
