Knuth is a unique character. I read the more personal of his books last year, "Things a Computer Scientist Rarely Talks About". It's essentially a transcript of several open lectures he gave at Stanford on topics ranging from his hobbies and side-projects to his thoughts on the Bible and his Christian faith. I've been a staunch atheist for the majority of my life, but seeing Knuth talk so comfortably about his spirituality actually helped me appreciate religion more.
What's the little book of his about a man and a woman trapped on an island where they geekily explain things to each other? I might be misremembering the setting...started it once but it was pretty cheesy.
For some reason, I stumbled across this website way back in August, before it was at all publicly discussed or advertised. So I secured tickets early on, filed for vacation and am gonna enjoy this so much.
