Does the statement, "We've always done it that way" ring any bells... ?  

The US standard railroad gauge (distance between the rails) is 4 feet, 8.5 inches. That's an exceedingly odd number. 

Why was that gauge used? 

Because that's the way they built them in England, and English expatriates built the US Railroads. 

Why did the English build them like that? 

Because the first rail lines were built by the same people who built the pre-railroad tramways, and that's the gauge they used. 

Why did "they" use that gauge then? 

Because the people who built the tramways used the same jigs and tools that they used for building wagons, which used that wheel spacing. 

Why did the wagons have that particular odd wheel spacing? 

Well, if they tried to use any other spacing, the wagon wheels would break on some of the old, long distance roads in England, because that's the spacing of the wheel ruts. 

Who built those old rutted roads? 

Imperial Rome built the first long distance roads in Europe (and England) for their legions. The roads have been used ever since. 

Why are the ruts in the roads? 

Roman war chariots formed the initial ruts, which everyone else had to match for fear of destroying their wagon wheels.  Since the chariots were made for Imperial Rome, they were all alike in the matter of wheel spacing. 

The United States standard railroad gauge of 4 feet, 8.5 inches is derived from the original specifications for an Imperial Roman war chariot.  And bureaucracies live forever. So the next time you are handed a specification and wonder what horse's *** came up with it, you may be exactly right, because the Imperial Roman war chariots were made just wide enough to accommodate the back ends of two war horses. Now the twist to the story... 

When you see a Space Shuttle sitting on its launch pad, there are two big booster rockets attached to the sides of the main fuel tank. These are solid rocket boosters, or SRBs. The SRBs are made by Thiokol at their factory at Utah. The engineers who designed the SRBs would have preferred to make them a bit fatter, but the SRBs had to be shipped by train from the factory to the launch site. The railroad line from the factory happens to run through a tunnel in the mountains. The SRBs had to fit through that tunnel. The tunnel is slightly wider than the railroad track, and the railroad track, as you now know, is about as wide as two horses' behinds. 

So, a major Space Shuttle design feature of what is arguably the world's most advanced transportation system was determined over two thousand years ago by the width of a horse's rump.

You Might Be a Mathematician if...
-you are fascinated by the equation.
-you know by heart the first fifty digits of pi.
-you have tried to prove Fermat's Last Theorem.
-you know ten ways to prove Pythagoras' Theorem.
-your telephone number is the sum of two prime numbers.
-you have calculated that the World Series actually diverges.
-you are sure that differential equations are a very useful tool.
-you comment to your wife that her straight hair is nice and parallel.
-when you say to a car dealer "I'll take the red car or the blue one", you must add "but not both of them."

 

 Approximately ten excuses for not doing homework:
* I accidentally divided by zero and my paper burst into flames.
* I could only get arbitrarily close to my textbook. I couldn't actually reach it.
* I have the proof, but there isn't room to write it in this margin.
* I have a solar powered calculator and it was cloudy.
* I locked the paper in my trunk but a four-dimensional dog got in and ate it.
* I couldn't figure out whether I am the square of negative one or I am the square root of negative one.

 

A team of engineers were required to measure the height of a flag pole. They only had a measuring tape, and were getting quite frustrated trying to keep the tape along the pole. It kept falling down, etc. A mathematician comes along, finds out their problem, and proceeds to remove the pole from the ground and measure it easily. When he leaves, one engineer says to the other: "Just like a mathematician! We need to know the height, and he gives us the length!"


The physicist and the engineer are in a hot-air balloon. Soon, they find themselves lost in a canyon somewhere. They yell out for help: "Helllloooooo! Where are we?"
15 minutes later, they hear an echoing voice: "Helllloooooo! You're in a hot-air balloon!!"
The physicist says, "That must have been a mathematician."
The engineer asks, "Why do you say that?"
The physicist replied: "The answer was absolutely correct, and it was utterly useless.
