I received quite a jolt when I received the most recent issue of Mathematics Magazine, one of the mathematical journals that I subscribe to. The article contains an interesting article on combinatorics and train tickets entitled The Lucky Tickets; here’s the first page.

But I was a little surprised when I saw the pithy description of this article on the magazine’s front cover:

Yes, they really wrote “Getting lucky on a long train ride” on the cover of the magazine.

As this is a mathematical journal, it’s impossible to tell if this was a deliberate double entendre or an honest mistake borne of, in the words of Betsy Devine and Joel E. Cohen in Absolute Zero Gravity, a certain otherworldly innocence.

I'm a Professor of Mathematics and a University Distinguished Teaching Professor at the University of North Texas. For eight years, I was co-director of Teach North Texas, UNT's program for preparing secondary teachers of mathematics and science.
