Relative Understanding
A mathematician and an engineer attend a lecture by a physicist. The topic concerns KulzaKlein theories involving physical processes that occur in spaces with dimensions of 9, 12 and even higher.
The mathematician is sitting, clearly enjoying the lecture, while the engineer is frowning and looking generally confused and puzzled. By the end the engineer has a terrible headache. At the end, the mathematician comments about the wonderful lecture.
The engineer says, "How do you understand this stuff?"
Mathematician: "I just visualize the process."
Engineer: "How can you visualize something that occurs in 9dimensional space?"
Mathematician: "Easy, first visualize it in Ndimensional space, then let N go to 9."
