A Beautiful Mind

2008 was a difficult year for the Stallings and Walt families.

One of our more interesting characters, John Robert, died in late November. I always knew he was a brilliant person, but once he started talking about what he did every day, it was very much over my head.

These two articles about him "dumb it down" only a very little before they get into more depth, and I can no longer keep up.
