CT scanning, streaming videos, and sending images over the Internet wouldn’t be possible without the Fast Fourier transform. Commonly known as FFT, the computer algorithm designed by researchers at Princeton University and IBM is found in just about every electronic device, according to an entry in the Engineering and Technology History Wiki. Demonstrated for the first time in 1964 by IEEE Fellows John Tukey and James W. Cooley, the algorithm breaks down a signal—a series of values over t...
