What a loss for us all

I just learned of his passing and wanted to add my own sadness to our loss. Chris was such a delight to learn from. I will miss not being able to sit and enjoy the mind again. If the difference one has made in the world and in humanity is a measure of a life, he lived a great one that will continue to expand and grow. Thank you, Chris. My condolences, Natasha.
