PSALM TO AN ENGINEER'S SWEETHEART


This poem appeared in Ann Lander's Column on November 20, 1993. I think it is hilarious, although I don't entirely agree with the overall theme. But, I must admit, some of it sounds mighty familiar!

Verily, I say unto ye, marry not an engineer; for an engineer is a strange being and possessed of many evils.
Yea, he speaketh always in parables, which he calleth formulae. He wieldeth a big stick which he calleth a slide rule. And he hath only one bible, a handbook.
He thinketh only of strains and stresses, and without end of thermodynamics.
He showeth always a serious aspect and seemeth not to know how to smile.
He picketh his seat in a car by the springs thereof and not by the damsels. Neither does he know a waterfall except by its horsepower, nor a sunset except that he must turn on the light.
Always he carrieth his books with him, and he entertaineth his sweetheart with steam tables.
Verily, though his damsel expecteth chocolates when he calleth, she openeth the package to discover samples of iron ore.
Yea, he holdeth her hand but to measure the friction thereof, and kisseth her only to test the viscosity of her lips, for in his eyes shineth a faraway look that is neither love nor longing, but a vain attempt to recall formulae.
Even as a boy, he pulleth a girl's hair but to test its elasticity.
But as a man, he deviseth different devices. For he counteth the vibrations of her heartstrings.
And his marriage is a simultaneous equation involving two unknowns.
And yielding diverse results.
Verily, I say unto ye, do not marry an engineer.


A priest, a doctor, and an engineer were waiting one morning for a particularly slow group of golfers.
Engineer: What's with these guys? We must have been waiting for 15 minutes!
Doctor: I don't know but I've never seen such ineptitude!
Priest: Hey, here comes the greens keeper. Let's have a word with him.
Priest: Say George, what's with that group ahead of us? They're rather slow aren't they?
George: Oh yes. That's a group of blind fire fighters. They lost their sight while saving our club house last year, So we let them play here anytime free of charge!
(silence)
Priest: That's so sad. I think I will say a special prayer for them tonight.
Doctor: Good idea. And I'm going to contact my ophthalmologist buddy and see if there's anything he can do for them.
Engineer: Why can't these guys play at night?


There were three people ready to be executed by guillotine back in medieval days: a farmer, a blacksmith, and, an engineer.

The first was brought up to the platform and the henchman ask if he had any last words. The farmer said yes, that he would like to say a prayer. After kneeling down and praying, the henchman had him put his head through the opening in the guillotine and he pulled the chain. The blade came crashing down but stopped 2" from the man's neck. Everyone gasped and said for the henchman to let him go. This must be a sign from the gods. So, the guards let him go.

Next was the blacksmith's turn. After being asked if he had any last words, he too wanted to say a prayer. The same thing happened. When the chain was pulled, the blade came crashing down and stopped 2" from the man's neck. For the same reason, the guards let him go too. And as did the farmer, he high-tailed it over the mountains.

Lastly, the engineer was brought up onto the platform. When the henchman asked him if he had any last words he said "no", but pointed up to the top of the guillotine and said "there's a kink in the chain"

Then there was the story of the three engineers in a bar having a couple of drinks and brooding about what kind of engineer God is. "Of course God is a Mechanical Engineer", says the Mechanical Engineer," sure look at the human skeleton it's a marvel of joints, linkages, support and it gives such free movement of the body." "No way, God's an Electrical Engineer", piped the Electrical Engineer," think about the brain and the nervous system, it's an incredibly vast and complex electrical masterpiece!" "You're all wrong", said the Civil Engineer,"God's a Civil Engineer, what other engineer would run a waste water line through a recreational area?"
Three engineers and three accountants are traveling by train to a conference. At the station, the three accountants each buy tickets and watch as the three engineers buy only a single ticket. "How are three people going to travel on only one ticket?" asks an accountant. "Watch and you'll see," answers an engineer. They all board the train. The accountants take their respective seats but all three engineers cram into a restroom and close the door behind them. Shortly after the train has departed, the conductor comes around collecting tickets. He knocks on the restroom door and says, "Ticket, please." The door opens just a crack and a single arm emerges with a ticket in hand. The conductor takes it and moves on. The accountants saw this, and agreed it was quite a clever idea. So after the conference, the accountants decide to copy the engineers on the return trip and save some money (being clever with money, and all that). When they get to the station, they buy a single ticket for the return trip. To their astonishment, the engineers don't buy a ticket at all. "How are you going to travel without a ticket?" says one perplexed accountant. "Watch and you'll see," answers an engineer. When they board the train, the three accountants cram into a restroom and the three engineers cram into another one nearby. The train departs. Shortly afterward, one of the engineers leaves his restroom and walks over to the restroom where the accountants are hiding. He knocks on the door and says, "Ticket, please."

Everyday Engineering Problems


Answers are at the end.
  1. One day Ruth celebrated her birthday. Two days later her older twin brother, Jim, celebrated his birthday. How come?
  2. Why is it better to have round manhole covers than square ones?
  3. A man went to a party and drank some of the punch. He then left early. Everyone else at the party who drank the punch subsequently died of poisoning. Nothing was added to the punch after his departure. Why did the man not die?
  4. A man died and went to Heaven. There were thousands of other people there. They were all naked and all looked as they died at the age of 21. He looked around to see if there was anyone he recognized. He saw a couple and he knew immediately that they were Adam and Eve. How did he know?
  5. A woman had two sons who were born on the same hour of the same day of the same year. But they were not twins. How could this be so?
  6. A man walks into a bar and asks the barman for a glass of water. The barman pulls out a gun and points it at the man. The man says `Thank you' and walks out. What's going on?
SOLUTIONS:
  1. At the time she went into labor, the mother of the twins was traveling by boat. The older twin was born first early on March 1st. The boat then crossed the International Date line (or anytime zone line) and the younger twin was born on February the 28th. In a leap year the younger twin celebrates her birthday two days before her older brother.
  2. A square manhole cover can be turned and dropped down the diagonal of the manhole. A round manhole cannot be dropped down the manhole. So for safety and practicality, all manhole covers should be round.
  3. The poison in the punch came from the ice cubes. When the man drank the punch the ice was fully frozen. Gradually it melted, poisoning the punch.
  4. He recognized Adam and Eve as the only people without navels. Because they were not born of women, they had never had umbilical cords and therefore they never had navels. This one seems perfectly logical but it can sometimes spark fierce theological arguments!
  5. They were two of a set of triplets (or quadruplets etc.)
  6. The man had hiccups. The barman recognized this from his speech and drew the gun in order to give him a shock. It worked and cured the hiccups - so the man no longer needed the water. The is a simple puzzle to state but a difficult one to solve. It is a perfect example of a seemingly irrational and incongruous situation having a simple and complete explanation.

There was an engineer who had an exceptional gift for fixing all things mechanical. After serving his company loyally for over 30 years, he happily retired. Several years later his comapny contacted him regarding a seemingly impossible problem they were having with one of their multi-million dollar machines. They had tried everything and everyone else to get the machine fixed, but to no avail. In desperation, they called on the retired engineer who had solved so many of their problems in the past.

The engineer reluctantly took the challenge. He spent a day studying the huge machine. At the end of the day he marked a small "x" in chalk on a particular component of the machine and proudly stated, "This is where your problem is." The part was replaced and the machine worked perfectly again.

The company received a bill for $50,000 from the engineer for his service. They demanded an itemized accounting of his charges. The engineer responded briefly:

One chalk mark......................$1

Knowing where to put it........$49,999

It was paid in full and the engineer retired in peace.
