After a while, they’ve got air conditioning, flush toilets and escalators, and the engineer is becoming a pretty popular guy. One day God calls Satan up on the telephone and asks with a sneer, “So, how’s it going down there in hell?” Satan replies, “Hey, things are going great. We’ve got air conditioning, flush toilets and escalators, and there’s no telling what this engineer is going to come up with next.” God replies, “What? You’ve got an engineer? That’s a mistake, he should never have gotten down there, send him up here.” Satan says, “No way! I like having an engineer on the staff, and I’m keeping him.” God says, “Send him back up here or I’ll sue.” Satan laughs uproariously and answers, “Yeah right. And just where are you going to get a lawyer?”


Two engineering students were walking across campus when one said, ”Where did you get such a great bike?”

Next was the Muslim and he asked that he also be allowed to face upwards to look to Allah before his death. Again the guillotine stopped just short and his life was spared as well.
 The engineer was last and he too asked to face upwards given what happened with the first two. As he lay there, he looked up at the mechanism and said, “Aha, I see the problem!”.


An architect, an artist, and an engineer were discussing whether it was better to spend time with their wives or mistresses.

The physicist grabs a bucket and leap towards the sink, filled the bucket with water and puts out the fire. The second day, the same two sit in the same lounge. Again, the coffee machine catches on 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.

Explanation
One common approach for solving mathematical problems is reducing them to other, already solved problems, then making a reference to them.


When a statistician passes the airport security check, they discover a bomb in his bag. He explains. “Statistics shows that the probability of a bomb being on an airplane is 1/1000. However, the chance that there are two bombs at one plane is 1/1000000. So, I am much safer…”

Explanation
Even though the statement is correct, the statistician is not taking in account conditional probability. Obviously, his chances for safe flight are not changing by bringing a bomb.


An engineer, a physicist, and a mathematician are staying in a hotel. 
The engineer wakes up in the middle of the night and smells smoke. He goes out into the hallway and sees fire, then goes back to the room, fills a trash can with water, and douses it.
Later, the physicist wakes up and smells smoke. He opens his door and sees a fire in the hallway. He walks down the hall to a fire hose and after calculating the flame velocity, distance, water pressure, trajectory, etc. extinguishes the fire with the minimum amount of water and energy needed.
Later, the mathematician wakes up and smells smoke. He goes to the hallway, sees the fire and then the fire hose. He thinks for a moment and then exclaims, “Ah, a solution exists!”, then goes back to bed.

Explanation
In many mathematical problems, all you need to do is just prove that a solution, without finding it specifically.


A chemist, a physicist, and a mathematician are stranded on an island when a can of food rolls ashore. The chemist and the physicist come up with many ingenious ways to open the can. Then suddenly the mathematician gets a bright idea: “Assume we have a can opener…”

The engineer asks, “Why do you say that?”
The physicist replies: “The answer was absolutely correct, and it was utterly useless.”

Explanation
Many people consider mathematics to be very exact, but useless for real life.
