Fourier Quote by John Robinson Pierce
““Fourier succeeded in proving a theorem concerning sine waves which astonished his, at first, incredulous contemporaries. He showed that any variation of a quantity with time can be accurately represented as the sum of a number of sinusoidal variations of different amplitudes, phases, and frequencies.””
About This Quote
Fourier proved that any time‑varying signal can be decomposed into a sum of sine waves with distinct amplitudes, phases, and frequencies.
In simple terms: All signals are combinations of simple waves.
Complex phenomena can be expressed as sums of simple periodic components.
