My favorite video was you breaking down the Spanish castle and how they pumped water up with nothing put the power of the water's movement itself! Mind blowing and awesome animations. These old technologies are so cool and more complete/harmonious it seems. I'd love to see one on how cathedrals were built for sound resonance and natural cooling and time telling etc. though their architecture.

Rome is fun because schools can’t stop telling us about ancient Rome and mostly Native Americans for some reason I mean Columbus Day is tomorrow or indigenous peoples day but primal space I hope you didn’t ignore me last episode. I’m not being greedy. I just hope you’re not mad at me.😅

Damm, btw, i know it ain't releated but can you please do video about structure and instruments put inside new horizonts probe, i seen the video" how voyager 2 threaded a needle through space" and i like how detailed your explaining of its structure and instruments was, can you do same with new horizonts

Reinforced concrete has its own sets of problems; namely that the rebar rusts, expands, and cracks the concrete from within. Had they used metal reinforcements, I doubt we'd be able to appreciate it today.

I watch several people now who say rebar or metal in concrete almost guarantees failure because it expands and contracts with moisture. Roman concrete had a "natural healing" ability with excess lime and or a bacteria reaction. Pretty cool stuff and undeniably better then today's material considering it's still around today

Fortunate enough to visit this magnificant piece of engineering 😎

Stood outside and marveled at the tall pillars at the entrance. Stood inside in awe of the dome, and the engineering of the self-supporting dome. And just like the Colosseum, to touch 2,000 year old history.

That dome is hemispherical. If you filled the space with a sphere, it would be just touching the floor.

They used bottles and pottery in the cement of the dome to lighten it, or so I have read somewhere.

Seeing that there is so much that didn't survive the test of time I sometimes just think we'll that building just got lucky

Isn't it non - reinforced? Un- reinforced would mean someone removed the reinforcement from it. Right?

Did you know that the Pantheon in Rome has the world’s largest unreinforced concrete dome, built nearly 2,000 years ago? 🏛️ Its design was so advanced that modern engineers are still studying how it has survived earthquakes and time without reinforcement.
