Thanks a lot for giving me an opportunity to contribute to the Mathematica story. It was in the early 90’s. I was a regular visitor to the University of Illinois at Urbana-Champaign, and I did some work about the size of coefficients in polynomial decompositions which turned out to be useful in the algorithms used by Mathematica.

I remember that, at that time, I met Stephen Wolfram in Urbana, and, some years later, Conrad Wolfram in Paris.

I would like to emphasize the fact that Mathematica has certainly been a useful tool for research and teaching, but, not only that, it brought new questions to fundamental research. It brought new directions for research, which are still active today. So, I wish all the best to the Mathematica community for the next 25 years.
