 Moreover, the Fourier transform is essential in [[theories:​quantum_field_theory:​canonical|Quantum Field Theory]], where we usually expand any given field configuration in terms of it's Fourier modes and then start analyzing it.  Moreover, the Fourier transform is essential in [[theories:​quantum_field_theory:​canonical|Quantum Field Theory]], where we usually expand any given field configuration in terms of it's Fourier modes and then start analyzing it.
