If you are reading this text it is probably because you know Jean-Jacques, my Dad. While you know him professionally or more personally, I though it was a good idea to present him to you from the prism of his son. I will restrict myself to the scientifical part of our relationship, the rest being kept private.
My scientifical education started very early. Indeed, when I didn’t want to eat something as a child, he cut the food in the shape of rocket and other devices. He used this stratagem because he knew I was interested in technical stuffs and DIY’s. I was eager to leave school as soon as possible because his office was full of computer drawings and therefore working in real life appeared to me as very entertaining. Those drawings were actually Hoffman-Singleton graphs and Ulam spiral, which I didn’t know at that time.
