Celebrate Nelson Blachman, my father, on his 91st birthday (October 27, 2014) and your Mind

Although I was sad to hear of Nelson’s death, when I read this book, my spirits were immediately lifted and I was soon chuckling at his penetrating wit, and overawed at the depth and breadth of his erudition.”Ken Lever (profoundly influenced by Nelson’s approach to nonlinear systems analysis)
