Like most people, I enjoy a good mystery.

I don’t write traditional mysteries, but often my stories contain a secret that the characters have to solve. While I enjoy both reading and writing such novels, sometimes I enjoy real-life mysteries. I say sometimes because when it comes to, “why can’t I remember where the car is parked” or, “why politicians are such liars,” the answer is just annoying.

Recently, my son Robert sent me the one-panel comic from the website XKCD, by Randall Munroe, former NASA roboticist and current webcomic writer with a cult following.

I found his “What IF” section particularly amusing. If you have a weird sense of humor, and an interest in science, check out his website. ​
