To really see how these standardized artifacts have been used,
I will show you from the kingdom of Darius, a stone,
and this stone weighed about 60 kilos,
and this stone was used to see how much weight rice or wheat were having.
This stone weighed about 60 kilos as you can see.
Another proof of standardization was the use of carts.
We have found cart tracks all over the world,
and although the tracks are not the same,
but you can see it takes a long time to etch these tracks into rock bottom,
and because of that you can see that even carts which do not have
a real lifelong time to spend so that these tracks,
these carts were of the same measure during a long period of time.
Let's now go and see how the trading,
when trading became more important in the Mediterranean,
for instance the Venetian kingdom
had ports that they were using all over the Mediterranean,
they even had some areas that they were occupying.
They were using ships to go from one port to the other,
but in storms and on the sea and oars they broke,
pulleys went slower, sails did not work anymore,
so they had spare parts all over the Mediterranean to be able to
repair ships even if when they were not at home in Venice.
The Dutch did that in the 16th and 17th century,
they built ships that were able to transport a lot of notably wood in the beginning,
coming out of the Baltic Sea,
and so they also had their ships which was called a Fluitschip,
ships being able to be repaired all over the Baltic Sea,
all over the ports they were using to get goods from.
Then when the steam machine came in the mid of the 1850's,
when steam machine could be used for instance in textile
making when the warp and a weft could be interchanged
with each other by using a steam machine then these shuttles could
be shot into the warp and weave to make new cloth.
Having guns, they could break,
they could go broke,
so in the United States
when the Springfield company was using building muskets all over the country,
they were able to also make the broken parts,
make available all over the United States so that you could repair your musket.
At the end of the 19th century,
it became more and more clear that
using steam machines with the power vessels or the boilers as they were called in it,
