Here is an interesting story that ties together 2000 plus years of technology development.

The U.S. 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 is the way they built them in England, and the U.S. railroads were built by English expatriates. Why did the English people 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. Okay! Why did the wagons use that odd wheel spacing? Well, if they tried to use any other spacing, the wagons would break on some of the old long-distance roads because that is the spacing of the old wheel ruts.

So, who built those old-rutted roads? The first long-distance roads in Europe were built by Imperial Rome for the benefit of their legions. The roads have been used ever since. And the ruts? The initial ruts, which everyone else had to match for fear of destroying their wagons, were first made by Roman war chariots. Since the chariots were made for or by Imperial Rome, they were all alike in the matter of wheel spacing. So, why did the Romans pick that spacing? Because the Imperial Roman chariots were made to be just wide enough to accommodate the backends of two horses.

What's this got o do with the Space Shuttle? The engineers who designed the solid rocket boosters, or SRBs, wanted 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 to the factory runs through a tunnel in the mountains. The SRBs had to fit through that tunnel. The tunnel is slightly wider than a railroad track, and the railroad track is about as wide as two horses' behinds. So,in summary, a major design feature of the world's most advanced transportation system was determined by the width of two horses' behinds!!

PS I wrote this up (cleaning up an internet forward) about 12 years ago. It's still floating around on a number of websites.

Further research suggests that it may not be true at all.

Rob Kall has spent his adult life as an awakener and empowerer-- first in the field of biofeedback, inventing products, developing software and a music recording label, MuPsych, within the company he founded in 1978-- Futurehealth, and founding, organizing and running 3 conferences: Winter Brain, on Neurofeedback and consciousness, Optimal Functioning and Positive Psychology (a pioneer in the field of Positive Psychology, first presenting workshops on it in 1985) and Storycon Summit Meeting on the Art Science and Application of Story-- each the first of their kind. Then, when he found the process of raising people's consciousness and empowering them to take more control of their lives one person at a time was too slow, he founded Opednews.com-- which has been the top search result on Google for the terms liberal news and progressive opinion for several years. Rob began his Bottom-up Radio show, broadcast on WNJC 1360 AM to Metro Philly, also available on iTunes, covering the transition of our culture, business and world from predominantly Top-down (hierarchical, centralized, authoritarian, patriarchal, big) to bottom-up (egalitarian, local, interdependent, grassroots, archetypal feminine and small.) Recent long-term projects include a book, Bottom-up-- The Connection Revolution, debillionairizing the planet and the Psychopathy Defense and Optimization Project.
