What the technical achievements of mankind depend on ...

They sent me this letter, and the sender received this letter from someone else ... so the source of this idea is unknown to me.
If someone knows - tell me, I will indicate the author in the topic.

And do not judge strictly :)

So…
This is a very old bike, but now with illustrations.

On the sides of the Kennedy spacecraft are two engines, each 5 feet wide.
The ship designers wanted to make these engines even wider, but they could not.
Why?

image
The fact is that these engines ...

delivered by rail.

Which passes through a narrow tunnel.
image

The distance between the rails of the railway standard: 4 feet 8.5 inches.
If it were bigger, there would be wider cars, wider tunnels for the cars, and therefore the engines would have done more.
image

The question arises: why is the distance between the rails 4 feet 8.5 inches? Where did this figure come from?
image

It turns out that the railroad in the United States was made the same as in England
image

and in England, rail cars were made on the same principle as trams, and the first trams were made in England in the image and style of a horse tram. And the length of the axle was just ... right, 4 feet 8.5 inches! But why?
image

Because the horses were made with the expectation that their axles fell into the ruts on the English roads, that the wheels would wear less, and the distance between the ruts in England was just ... yes, you guessed it: exactly 4 feet 8.5 inches! Why so?
image
It’s just that the Romans began to make roads in Great Britain, bringing them under the size of their war chariots, and the length of the axis of the standard Roman chariot was equal to ... correctly, 4 feet 8.5 inches!

Well, now we have got to the bottom of where this size came from, but still, why did the Romans decide to make their chariots with axles of exactly that length?

But why: in such a chariot usually two horses were harnessed. And 4 feet 8.5 inches - it was just the size of two horse ass! It was inconvenient to make the axis of the chariot longer, since it upset the balance of the chariot.
image

Consequently, here is the answer to the very first question: even now, when a man went into space, his highest technical achievements directly depend on the size of a horse's ass two thousand years ago!

And here I sit and think ... probably the day will come when web developers will say:
"Well, it, this IE 6" ... :)
Not 2000 years for us to ride it.

Good Friday everyone :)
