ProofWiki:Jokes/Physicist Mathematician and Engineer Jokes

N-Dimensional Space
A mathematician, a physicist, and an engineer attend a lecture on Minkowski space.

Getting frustrated, the engineer asks, "How do you visualize 4-dimensional space?"

"Easy," replies the physicist. "Just imagine that each point of $\R$, representing a point in time, is associated with its own 3d space."

"There's an easier way," says the mathematician. "Just imagine N-dimensional space and set $N=4$."

Trivial Joke
An engineer, a physicist and a mathematician find themselves in a joke.

After consulting his slide ruler and TI-84 calculator, the engineer realizes the situation and starts laughing.

The physicist then understands too and chuckles to himself happily, as he now has enough experimental evidence to publish a paper.

The mathematician is perplexed, as he had observed right away that he was the subject of a joke, and deduced the presence of humor from similar jokes, but considered this joke to be too trivial a corollary to be significant, let alone funny.

Experimental Equations
After running many empirical tests, a physicist works out a set of equations explaining the data.

He asks a mathematician to check them.

A week later, the mathematician calls and says, "I've checked, and your equations are nonsense."

"But these equations accurately explain the data from my experiments. Are you sure that they are complete nonsense?"

"Well they aren't complete nonsense, but the only case in which they have solutions is the trivial one where the field is Archimedean."
