In Harmonic Analysis the uncertainty principle can be succinctly stated as follows: a nonzero function and its Fourier transform cannot both be sharply
Another way to express the meta uncertainty principle is: A nonzero function and its Fourier transform cannot both be sharply concentrated.

THE FOURIER UNCERTAINTY PRINCIPLES KABIR DUBEY Abstract Over the past century Fourier uncertainty principles have been highly active area of study Despite their far-reaching implications theinequalities have simple origins in mathematics In this paper we arrangesome foundational and powerful perspectives 2 Properties ofLp
THE UNCERTAINTY PRINCIPLE FOR FOURIER TRANSFORMS ON THE REAL LINE MITCH HILL Abstract This paper will explore the heuristic principle that a function on the line and its Fourier transform cannot both be concentrated on small sets We begin with the basic properties of the Fourier transform and show that a function and its Fourier
The Fourier components interfere constructively within the bumps at each integral multiple of L and interfere destructively otherwise III THE FOURIER TRANSFORM To eliminate the periodic structure we need to include even more Fourier components; for example it should be clear that we have to include Fourier functions whose period is longer
Fourier transform to characterize and understand molecular structures optical physicist use Fourier series to decompose and resconstruct ultrafast photonic pulses and particle physicsts use the ideas of orthogonal basis and Fourier coef- cients to describe the wave functions of particle states
