A mathematician and his best friend, who is an engineer, attend a public lecture on the subject of geometry in thirteen-dimensional space.

"How did you like that?" inquires the mathematician after the talk.

"My head's spinning", the engineer confesses. "How can you possibly develop any intuition for thirteen-dimensional space?"

"Well, it's not that hard", replies his friend. "All I do is visualize the situation in n-dimensional space and then let n = 13".
