'The big question is how he managed to get more than 3oz of differential equations past airport security'

Matt Blaze and Ade Barkah have fun with the story about the mathematician mistaken for a possible terrorist:

Blaze: The big question is how he managed to get more than 3oz of differential equations past airport security.

Barkah: He allegedly broke them up into partial differential equations…

Nice!

Thanks to Mark Liberman (Language Log) for the pointer.
