In my opinion, he should be proud of what he accomplished. I regret that you weren't happy with the article. We'll try to do better next time. [-Rick-]

We could make a template (say in MS Word) for the paper, and the author could have any format they wanted for the presentation itself. Then we could publish (place on the web site) the papers in a standard format. This would put the extra work on the authors rather than the organizers. In addition, a lot of times the presentation (power point) doesn't have all the information on the slide needed to stand alone. Having the authors include a paper would solve this problem. Maurice

That makes it only consequential to future kids to dream up sinusoidal decomposition on their own, in isolation, and overnight. While it's perfectly legitimate for them to feel proud for thinking in the right direction, this does not mean that we let poor Fourier be condemned to historical oblivion :). I only mean for this to be a light-hearted closure for what may be perceived as drama on my part. End of the day, I shouldn't push my luck too much with the experts in the field. -Momo
