My only quibble is that the article is about the discrete Fourier transform.
shash•2h ago
It’s usually easier to explain the dft. and easier to do a periodic function than a totally arbitrary sequence.

>The Fourier Transform is one of deepest insights ever made.

No, it is not. In fact it is quite a superficial example of a much deeper theory, behind functions, their approximations and their representations.

fedsocpuppet•4h ago
The Fourier transform predates functional analysis by a century. I don't see the point in downplaying its significance just because 'duh it's simply a unitary linear operator on L2'.
NewsaHackO•3h ago
But is it the deepest insights ever made?
badlibrarian•2h ago
The Fourier Transform isn't even Fourier's deepest insight. Unless we're now ranking scientific discoveries based on whether or not they get a post every weekend on HN.

The FFT is nifty but that's FINO. The Google boys also had a few O(N^2) to O(N log N) moments. Those seemed to move the needle a bit as well.

But even if we restrict to "things that made Nano Banana Pro possible" Shannon and Turing leapfrog Fourier.

Glad I'm not the only one who noticed there is a weekly (or more) post on what Fourier transform is.

zkmon•5h ago
It is more about the duality between the amplitude and frequency spaces and conversion between them. A bit similar to Hadamard gate for transforming a quantum state from computational basis to diagonal basis.
kens•4h ago
If you're dealing with computer graphics, audio, or data analysis, I highly recommend learning Fourier transforms, because they explain a whole lot of things that are otherwise mysterious.

My favorite application of the Fourier transform is converting convolution into pointwise multiplication. This is used to speed up multiple sequence alignment in bioinformatics.

If anyone wants to learn about the 2D DFT, the best explanation I've ever read was the relevant chapter in Digital Image Processing by Nick Efford.

If anyone wants to see my favorite application of the 2D DFT, I made a video of how the DFT is used to remove rainbows in manga on Kaleido 3 color eink on Kobo Colour:

In the video you show a 2D mask to blur diagonal lines. How is that mask applied to the DFT? Is the mask also converted to a DFT and the two signals get combined?

The absolute best teaching of the Fourier transform I've ever encountered is the extremely bizarre book "Who is Fourier?"
