As people here work in various jobs / professions they might know things from work or study no one here knows yet. this is what this topic is about.

what do you know that we have never heard of?

Eg: you don't need to be great at maths to be an architect

this is obvious to me but everyone says to me "i wanted to be an architect but i was bad at math,i can barely add"

Before a big mining strike in Arizona (1970s/80s) the company paid everyone in cash in $2 bills. The idea was that all local businesses would see where their money was coming from.

Some that because the media tend to use the triple barrelled name, as Mark chapman might be too common.

In the the Middle Ages, a type of clay – called ‘pygg’ – was used to make pots that could store money. This is where we get the name piggy bank from.

There were no magpies in Ireland until 1674. Gerald of Wales, while travelling across the island in the 1180s, made no mention of the presence of any during his stay in the country.

The first sighting of magpie is believed to be in County Wexford in 1674 when a small flock of about a dozen birds were blown across the Irish sea during a storm and began to breed in the Baronies of Forth and Bargy and eventually spread across the country.

The popular Christmas carol, Silent Night, was first performed on the 24th of December, 1818 in the town of Oberndorf bei Salzberg, Austria.

Eggs require a total of 21 days for full incubation to hatching. At 9 days the blastoderm or embryo of the chick remains largely unformed. It would appear that a number of interests are developing this type of technology to aid sex determination down to just a couple of days after an egg is laid

Agreed. Hopefully, though, they'll be able to do it before the embryo develops beyond a few cells... I seem to remember reading somewhere ages ago that they were trying to do it by testing the eggs' DNA - I don't know if they've got to that stage yet, but if they could do it by testing the shell, it would be a fantastic improvement.

"What's the big deal about railroad tracks?

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?
Well, because that's the way they built them in England, and English engineers designed the first US railroads.

Why did the English build them like that?
Because the first rail lines were built by the same people who built the wagon tramways, and that's the gauge they used.

So, why did 'they' use that gauge then?
Because the people who built the tramways used the same jigs and tools that they had used for building wagons, which used that same 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 more often on some of the old, long distance roads in England . You see, 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 (including England ) for their legions. Those roads have been used ever since.

And what about the ruts in the roads?
Roman war chariots formed the initial ruts, which everyone else had to match or run the risk 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.

So the next time you are handed a specification/procedure/process and wonder 'What horse's ass came up with this?', 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 launch 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."

There's a stone outside Pearse Street Garda Station which you'll almost certainly have seen if you've been around the area. It's really bland and easily ignored. But it's a replica of the stone the Vikings erected on the riverbank when they first docked at the Liffey. The original stood there for almost 1000 years before being stolen in the late 18th century; the replica was erected in 1986.

So the stone is placed at what was the edge of the river in the 9th century - but now it's a good 100 yards away.

And further again... By all sorts of twists and turns the Poddle reaches the environs of Dublin Castle, which in medieval times was the eastern edge of the city, the channel was diverted around the side of said castle as a defensive moat. To make it more of a defence it was dammed to keep the water deep, and that gentle reader is how Dublin's "Dame Street" got its name. In old English "Dam" was spelled "Dame" and over time the pronunciation matched the old spelling.

You can see said Dam here (best viewed on pc or tablet). Move the slider on the left to the year 1230 onwards to see it.

The width of the Liffey is staggering when you go back far enough.

Another slightly oddball factoid about the Poddle is that when it meets the Grand Canal at Harold's cross it passes under it. And when it comes near to its end where it joins the Liffey it widened out into a large dark pool, Dubh Linn and where we get the name of the city(Baile Atha Clia me bollex

)

While Dubliners today usually think of the Liffey* as the lifeblood and riverine soul of the city it was the now mostly buried and mostly forgotten little stream of the Poddle that powered the engine of the city and protected, fed and watered its land and people.

*the Liffey name comes from the floodplain around it which was great for farming. Then Anna Liffey, anglicised from from Abhainn na Liphe(sp). The two Irish rivers known by Roman writers were the Shannon and the Liffey. On the word "Abhainn"; the river Avon in England gets its name from the same word. When Romans asked locals what was the river called, they naturally used the Gaelic word for "river" Abhainn/Afon which became "Avon" over time. So to someone who speaks both languages it's actually called the river river.
