Imagine discovering epoxy resin and wanting to show it off to your ruler just to get executed.

They’ve actually figured out the secret to Stradivari Violins in like 2014 or something. Stradivari pickled his wooden planks for months before carving. Doing this burst the cell wall of the plant cells making the wood a more uniform piece in a microscopic level. This combined with the climate of the time he was working, and he used old growth trees which bore exceptionally hard and dense wood. I’m pretty sure it’s something like that but even if I got it wrong I know it’s no mystery anymore.

I find it interesting people are talking about about Damascus steel in the modern sense. Well not really, because most are unaware the Damascus steel popular today is not what the Crusaders would have called Damascus. Instead the steel first called Damascus by Crusaders is what today is called Woots steel. While we know how to make Woots steel today, the mystery is how they did it then.

Okay, I guess.

I wonder if everyone thinks the civilization before them was stupid af even tho they’re the reason why we have the tech we have now

The most intressting theory for how the pyramids were built that I have heard is that they gradually burried the pyramid in sand to drag the stone blocks up the sand like a ramp and then they removed all the sand once the pyramid was built.

An indestructible glass that has the transparency of glass but the toughness and bendiness of rubber?
... Isn't that just plastic?

the Antikythera Mechanism is nowadays pretty well understood. they know 90% of its functionality, they know it's not the only one of its kind, nor the first to have been made. they know who built it and they know how they could have built it. I suggest you watch Clickspring's series. He is in the process of recreating the mechanism true to how the greeks would have done it, and even wrote his own research papers on it.

The violins sounded so good because in part because the wood that was used was distinctive and special. During what's known as " the little ice age" when the English had the year without a summer, it affected the growth of trees. This particular species grew denser and that wood was used to make the infamous violins. They cannot be replicated since that particular wood isn't available in the same quality. Very interesting.

We do know how Damascus steel is made, at least today. You take two slightly different steel alloys, stack them on top of each other, and fold them a lot before forging the sword. Alec Steele here on Youtube makes a lot of Damascus. It would be a lot of work in that time but it's certainly possible. Disclaimer: I'm not a blacksmith or a material scientist.

This video feels very AI scripted and AI voiced... A lot of the facts are straight up false.

Why wouldn't the glass bender at least ask the empire to tax him on glass he sold

Why do people always underestimate that ancient civilisations can’t be smart at all or can’t have a weird hobby, just because they made something really good back then doesn’t mean it’s impossible, smart people ( even back then ) find sophisticated ways to make great things. Like the round rocks for example, they could literally just be a hobby those people had to pass time and bond

best dude to explain chill, straight to the point, no lame intro and insanly good explanations keep going bro

“…and are over 2 meters in Diameter. That’s over 6ft tall in hamburger units” 😭😭

[claysoggyfries]

It’s kinda hard to not feel like bendable glass isn’t just plastic :(

[MzN...]

The best thing i like in this video is "Let's get right into it".
Most YT videos getting me hate my life before start talking. Thanks man, you earn a subscriber.

They just used glitches that were patched long ago.

One thing is for certain, humans in the past were a lot more advanced than we anticipated.
