It was with shock and disbelief that I learned the passing of Professor Rajeev Motwani of Stanford University, technical adviser and angel investor in numerous companies, including Google. I was introduced to him by a mutual friend a few months ago. I had read his research papers, and I discussed with him one of my favorite technical obsessions: relational data models and how they intersect with programming languages. He was intrigued by the idea, and suggested we should cooperate on researching it further. I was going to write up a research proposal of sorts, and was looking forward to work with him. Professor Motwani, you will be missed.
