It should be noted that the muslims world did not have the precursors to movable type: Printmaking. They did not print textiles or clay scriptures.
The persians knew how weave linen textiles and carpets from fine materials. They later imported textile printing from South India with the Moghuls, fabrics called "Kalamkari". But the Persians did not apply ...
Much like Arabic, Persian script (الفبای فارسی) is difficult to write, with characters 'changing' depending on context. Think of a text consisting of many, many ligatures. And like in China and Japan the most beautiful calligraphy was held in high esteem.
Reproducing this in print is an enormous challenge, today. For much of the early history of print, ...
The strength and longevity of Roman marine concrete is understood to benefit from a reaction of seawater with a mixture of volcanic ash and quicklime to create a rare crystal called tobermorite, which may resist fracturing. As seawater percolated within the tiny cracks in the Roman concrete, it reacted with phillipsite naturally found in ...
It's hard to say what people "really think". Certainly in the 19th century the seed had already been planted. Beginning with a series of pulp novels starting with "The Steam Man of the Priaries" in 1868, mechanical men were nearly a subgenre in the 19th century.
Knowing what we know now, yes, it seems completely ridiculous that an intelligent being could ...

In Egypt, I think the Low-Nile part, under Hyskos, obtained some horse vehicles but the Egyptians built them by themselves later
During the Middle Age, can't recall of specific examples but I am sure some technologies (especiallly farming technics) migrated from abbey to abbey without a continuous ...
This question is way too basic and can be answered with a single link:
In 1912, New York, London and Paris traffic counts all showed more cars than horses for the first time.

For personal traffic transport it was even:

For central Europe, between 1925-1930 may be considered realistic.
For France possibly sooner due to a higher motorized density between 1920 and 1930.
The transition was uneven due to certain conditions
commercial was faster than private motorised vehicles
but the private use was probably a much smaller percentage than commercial, so in a city a ...
