I could be mistaken but I think another ChatGPT discussion on HN had people saying it would sometimes cite sources, and other times just make them up.

>> Explain briefly what the Fourier Transform is. Provide sources with more information about the topic.

>> The Fourier transform is a mathematical technique that decomposes a function or signal into its constituent frequencies. It allows us to represent a function in terms of the frequencies that make it up, rather than in terms of its time or spatial behavior.

The Fourier transform has many applications in a variety of fields, including signal and image processing, engineering, and physics. It is a fundamental tool in the analysis of periodic phenomena and is widely used in the study of waves and oscillations.

For more information about the Fourier transform, you may find the following resources helpful:

Wolfram MathWorld: http://mathworld.wolfram.com/FourierTransform.html

If you ask for an arxiv or pubmed link it also happily makes a link up. But the link just leads to a random paper.

woah! No need for the "explain briefly" part but when I asked for 50 references it wanted money.
