Incredible! It’s amazing to think about how so many old texts like this one could’ve been lost to history if someone hadn’t taken the time to erase the page to write something else on it.
There are even older clay tablets from Sumer that have a form of calculus. It is easy to regret lost knowledge like this. What could Galileo have done with calculus? But don't. There IS a reason we advance as we do. Timing is everything.
The explanation for the estimate of Earth's circumference leaves out one important detail. That is how to know when it is high noon in a distant city so you could measure the shadow in another city at the correct time. You can't call Archimedes up and ask, ''Hey buddy is it midday over there yet? I want to measure the shadow over here.'' It seems way too inaccurate to use caravan schedules to measure the time. I'd be inclined to used sand clocks. You would need a huge hourglass (or 24 hourglass) to measure the time required for a long morning shadow to shrink to zero at midday. A traveller would need to know in advance how long it would take from setting out until the shadow was zero at his place of departure. And that time would also need to be sufficient for the traveller to reach his destination carrying the sand clock. Then when the timer ran out, the traveller would know it was noon at the departure location. And he could then measure the shadow at the destination location.
It's a trivial thing to know when it is exactly midday, it is when the sun is at its highest point in the sky! Even the ancient people of the stone age know this.

physics and history? two of my favorite topics :D great upload, sad I only found out about it now. Will definitely check out more of the channel

These lectures always sound more authoritative when
delivered in a German accent.!
great video

What's hidden beneath the writing in the book of kells?
If you have to destroy the artifact to get the data, I'm fine with that. I find information far more valuable than media.

2025 here. bump this up a bit on youtube
sort of boring
People who don't like to learn are the boring ones.
