An electrical engineer, a structural engineer and a civil engineer were walking along discussing religion.
The electrical engineer said "I believe God must've been an electrical engineer. Just look at the incredible complexity of our nervous system and brain".
The structural engineer thought for a moment and responded "I think he was surely a structural engineer. Look at how marvelously engineered the bones and muscles are and how flexible and strong the body is!".
"Nah!" said the Civil Engineer, "he was definitely a civil engineer. Who else would've put a sewer line in right next to a recreational area?"
A mathematician sees one person enter an empty building and two come out. He says “Great…one more in and the building will be empty again.”
A mathematician is asked to design a table. He first designs a table with no legs. Then he designs a table with infinitely many legs. He spends the rest of his life generalizing the results for the table with N legs (where N is not necessarily a natural number).
A Mathematician, an engineer and a physicist were traveling through Scotland when they saw a black sheep through the window of the train.
"Aha", says the engineer, "I see that Scottish sheep are black."
"Hmm", says the physician, "You mean that some Scottish sheep are black".
"No", says the mathematician, "All we know is that there is at least one sheep in Scotland, and that at least one side of that one sheep is black!"
A physicist and a mathematician are sitting in a faculty lounge. Suddenly, the coffee machine catches on fire. The physicist grabs a bucket and leaps towards the sink, filled the bucket with water and puts out the fire. Second day, the same two sit in the same lounge. Again, the coffee machine catcheson fire. This time, the mathematician stands up, got a bucket, hands the bucket to the physicist, thus reducing the problem to a previously solved one.
