As Vijay pointed out, we were all complicit in the belief that Obaid would simply always continue to be there. Thus, it is even more saddening to hear of this tragic loss. As students, we all looked up to Obaid to remind us that there were never any limits to our thinking and that no scientific problem was too big. It was this calm intrepidity that I found most admirable. I owe him a huge sense of gratitude for his wisdom and advice not just on how to think about science but also the very real nuts and bolts of electrophysiological experiments. There is no doubt that his legacy does and will continue to live on. It will perhaps be the best tribute that we can all pay him. My heartfelt condolences.
