Romans did this, i had no idea the ancient Roman empire existed 4 about 1000 years until 1809. 1809!?Also I did not know ancient Romans were mostly germanic as a first language, i just looked it up on wikipedia. Somehow i thought the roman empire were Italians, speaking Latin. In fact, history says many Italians came to California to build the concrete dams. Must have missed a history lesson while studying physics.

The notion of "fictitious force" arises in Einstein's general theory of relativity. The way all masses in free fall descend at the same rate led Albert Einstein to wonder whether gravity could be modeled as a fictitious force. F = ma the size of the force can be determined by the size of the mass and how much the mass is accelerating at. But all masses in free fall accelerate at the same rate of acceleration, that would mean if gravity is a force then that force changes for each object. He noted that a free falling observer along with various items in a closed box would not be able to detect any force at all, for they would all have no weight. In other experiments using a scale various items have various weights; hence, free falling reference frames are equivalent to force free inertial reference frames (the equivalence principle). Developing this insight, Einstein formulated a theory with gravity as a fictitious force, and attributed the apparent acceleration of free fall due to observers watching from a non-inertial reference frame while they are being accelerated by a force, and to the curvature of spacetime, which is a force free inertial reference frame. This idea underlies Einstein's theory of general relativity. NIST WTC FAQ 31. How could the WTC towers collapse in speeds that approximate that of a ball dropped from similar height in a vacuum (with no air resistance)? NIST --> "Since the stories below the level of collapse initiation provided little resistance the building section above came down essentially in free fall."

It's an old series funded by EU money, and was shown in highschools 30 years ago, to entice peoople to study engineering. Why would they travel outside EU, if they can find examples in Europe. As an example; European skyscrapers arent built in the same style as American ones, so no reason to go to New York to show it. The Eiffel tower is built on the same principles, and shows it much better, because the frame is still visible and not covered up.

Mr Scott Steedman this is NOT true that it was Romans who had the technic of Arch building, in fact, I have seen probably the world's first Arch in Iraq, Babylonian times more than a thousand BC.

A lot of these structures waste space and lack practical purpose. I've seen the same space-wasting design at a hospital that included a dangerous balcony that children could fall off. Mostly I'm talking about modern architecture.

[@clevelandexplorer2221]

I'm not sure whether it's the same building and I did unfortunately miss a bit when seeing to the oven but the cathedrals dome was built long after the architect died, with his plans being mental rather than logged. So they didn't know how to build said dome until one guy approached authorities promising to build one with dirt and the public. So they built a mound in the cathedral to hold the dome while under construction, and invited the public to dig said dirt back out, enticed with randomly hurried coins within
