The Fast Fourier Transform (FFT), introduced by Cooley & Tukey in 1965, is a crucial algorithm in signal processing and data analysis, reducing computation from O(n^2) to O(n log n). It has roots in Gauss's earlier work and is essential in various applications like radio telescopes, JPEGs, audio codecs, and quantum mechanics.
