THE QUANTUM STAIRCASE

Energy learns to count: packets, rungs, a ruler for light, and the clock inside the atom.

1

PHOTOELECTRIC

E = hf − φ — below threshold, a floodlight ejects nothing; above it, a glimmer.

BOHR ATOM

Only the rungs exist — and the jumps between them are Balmer’s lines, to the nanometer.

GRATING

d·sinθ = mλ run backwards — measure an angle, recover the light, residual zero.

HALF-LIFE

N(k·t½) === N₀/2ᵏ bitwise — the law of halves as an identity, no dice anywhere.
