A brief tribute to Leif:

As I did not realize that Leif had started a blogspot blog, I have been greatly missing out. But now that I have come across it I have enjoyed catching up on His posts and the comments on them. Leif is a great thinker and is very challenging in how he presents his thoughts. While I have a few sources that have been challenging me since I have left college, Leif has a way of presenting his thoughts in a clear manner and of inviting thought-provoking comments. Over the last few years he has become both a friend and great teacher to me. I'm sure most people who read this are already aware of Leif's posts over the summer, but for those who are not I highly recommend reading over any or all of his posts.
