This photo was taken on Brian's birthday in 2012. I flew back to California from New Jersey to watch a 49ers game and stopped by late at night after the game to surprise Brian. I love this photo so much, especially Brian's massive smile!

There have been some amazing gatherings in this home over the years. During these gatherings, Professor Zhang's brilliance shined. Two things Professor Zhang always brought - extremely challenging questions and a really hearty laugh. We'd always leave these gatherings a little smarter and a lot more motivated.

We all miss you so much, Professor.
