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 p re-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.
>
> So 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.
>
> And 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. Therefore the United States standard railroad gauge
of 4 feet, 8.5 inches is derived from the original specifications for an
Imperial Roman war chariot. Bureaucracies live forever.

wonder 'What horse's ass came up with it?' you may be exactly right.

> Imperial Roman army chariots were made just wide enough to accommodate the
rear ends of two war horses. (Two horses' asses.) 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 in
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 launc h site. The railroad line from the factory happens to run through
a tunnel in the mountains, and 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 ass.
>
> And you thought being a horse's ass wasn't important? Ancient horse's
asses control almost everything....and CURRENT Horses Asses are controlling
everything else!!

That is great. We should be teaching the kids to go out and take a close look at a horse's ass. I would call that project based learning!!
