The Fourier transform and its computational offshoot, the Fast Fourier Transform. We wouldn't have any of modern electronics and telecommunications without the mathematical insight that the FT brought. The fact that you can go from the time domain to the frequency domain and back again is nothing less than astounding. Optics was also benefitted by the FT because you can use is to filter unwanted optical frequencies and diffraction effects from your images using Fourier transformation. |
