This man showed that if the position wave function is localized then the momentum wave function is infinitely unlocalized in a theorem named for him and Paley.
This man showed that if the position wave function is localized then the momentum wave function is infinitely unlocalized in a theorem named for him and Paley. His books include one once dubbed "The Yellow Peril" for its cover but actually entitled "Extrapolation, Interpolation and Smoothing of Stationary Time Series" and one more humorously entitled God and Golem, Inc. He postulated that the power spectrum of a signal is the Fourier transformation of its autocorrelation function in a theorem with Khintchine. He's the namesake of a tauberian theorem as well as ►a filter which reduces noise present in a signal and a process exemplified by Brownian motion, but he's even better known as the founder of cybernetics. FTP, name this mathematician who may have also had a really big head.
