Why “biquadratically” is a great word
Relating to or involving the fourth power of a quantity. Formed from the adjective 'biquadratic' (from 'bi-' (two, twice) + 'quadratic' (relating to the square of a quantity), from Latin 'quadratus' ("square")) + the adverbial suffix '-ally'. Unlike "linearly," which describes a steady, first-order progression, or "quadratically," which charts a gentle parabolic arc, biquadratically describes a relationship of steep, almost violent acceleration. It is the ferocious bloom of a nuclear chain reaction, the way compound interest forges an empire from a whisper of capital, the surge of a pandemic where each carrier spawns a geometric cascade. It is the mathematics of things that cannot be contained, the curve that outpaces intuition and whispers a warning about the hidden violence of exponentiation.
