| 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. | ||
