My famiy and I had a special relation with Tapan. It is difficult to explain and summarize it in few words, but I will try.
He was neither my colleague, nor my professor. In fact, I never understood too much of his work. Just as an example, I attended with my family the ceremony where he received his Doctorate Honoris Causa in Madrid. I was translating his speech to my mother, and the only part that I understood, and could translate, was that the most important piece of a cell phone was the antenna. That was all I got.
But there are a lot of things that I undertsand.
When my wife and I went to Syracuse, as I was studying there my Master´s Degree in Public Administration, he helped us with everything we needed. That, I understand and appreciate.
I understand that Tapan was a colleague and close friend of my sister Magdalena. They worked together, wrote together, taught together, traveled together.... They, in fact, shared great part of their lives. Even my mother met him quite often, and liked him a lot.
Tapan often came to my home. He spent some time with us when we were in Brazil and once again in my house in Madrid. He always had a great time with my children. Being so different, I was amazed how much they enjoyed each other. In fact, I believe that my son Carlos is now studying air and space engineering partially due to his influence.
And I do understand that my family and I will miss him a lot.
