We are celebrating in France the 250th anniversary of Joseph Fourier, who is relatively little known as a mathematician. He had many activities, including being a Prefect (Governor), published little but a book on the heat theory (The analytical heat theory at E. Britannica, and a translation with notes). There barely is a street name, and meanwhile JPEG or MP3 are directly related, possibly there is a 30% to 50% chance that every-time a computer runs an FFT.
I would be interested in asking a question about Fourier theory, and its interpretation, open questions, and most important messages. But this could become opinion-based quite quick. So:
How appropriate would it be to ask generic questions using celebrations, anniversaries, at the risk of becoming opinion-based?
