  "description": "The Fourier Transform (Joseph Fourier, 1807) decomposes a signal into its constituent frequencies. It is fundamental to signal processing, image compression (JPEG), audio processing (MP3), and MRI reconstruction. FFT (Fast Fourier Transform, Cooley-Tukey 1965) reduces complexity from O(n²) to O(n log n).",
