Once, a postal letter-carrier asked me why I scribbled “nonorientable” on my package. I began to tell her the mathematical meanings of the word, and she interrupted me to say that she knew its meaning - she wanted to know what kind of topological shape was in the box. Wow: she knew topology!

Since then, I scribble it on every box I mail, in honor of her.

Any previous doubts I may have had regarding the authenticity of this "CliffStoll" account have now evaporated. ;-)

Thank you, Cliff, for all that you've done. Clearly, you've left a mark on many souls... and we're all the better for it. :-)
