Ancient Amazonian Cities [3 examples...kind of] 

Hey big dog great channel you got there.

Fancy seeing you here! Lol

So happy to see my favorite creators are connected! 🍀🦋

From which channel.. there are a lot video with the same name

Found this channel from yours...both are epic! Thank you fellas!

There a few, there is one about a woman working in physics and she shares advances and papers about cosmology and news about the JWSP

Anton Petrov does this, too. He's also very relatable in his own unique way, just like Stefan. 🍀

There's a great weekly radio programme that does this for earth systems sciences: Radio EcoShock. An hour a week with two or three interviews with authors of the studies in question. Archive goes back about a decade and a half, everything is available on the website. Paul Beckwith makes frequent videos here on YT in which he breaks down new climate science studies for lay people. He does these for the content, not the presentation, i.e. they're very informative, not flashy. Anton Petrov, of course, natural science videos every day pretty much, mostly about new research. If you want something more niche, Russell Barkley, a retired psychiatrist specialising in ADHD, does a brief research update every Friday, also here on YT. There are also some Religious Studies scholars with great academic YT channels for lay people. They don't necessarily focus on recent papers, but do present much up-to-date information from their field for the rest of us: Religion for Breakfast, Let's Talk Religion, Esoterica and Angela's Symposium. Plus some specialised ones = Bart Ehrman on the New Testament and Al Muqqadimah on the (secular) history of Islam. The latter guy isn't a scholar himself but he does produce academically informed content of great quality.

I'm not fond of the conquistadors, but you have to respect their boldness.

There's a movie about the expedition of Don Lope de Aguirre. Is some respects it's a boring as batshit, but that in itself conveys what it would've been like floating down a river as you die from starvation, disease, insect bites and hostile locals.

@@theflamingone8729 Directed by Werner Herzog.

@@MarcosElMalo2 and starring Klaus Kinski, the most insane human being to ever grace a film set am i right in remembering that he was so bad to work with, half the crew offered to kill him? 😭

@@MarcosElMalo2 don't get me wrong, it's worth watching.

Im in the “business” so to speak and there’s for sure a revolution in the field going on right now. Laser scanning is being used heavily to create what is called digital twins. This is something that came from aerospace engineering that is now being applied to cities. The lasers/sensors themselves have gotten a lot better, a lot lighter, and a lot cheaper. Same things have happen ld with drones. Also we have better software for error correction of gnss signals. The result is that you get high quality and very dense point clouds, Much much denser than what is possible from an airplane, at way less cost and complexity.

​@@00CooG00Is this stuff available to regular people at a reasonable price?

And there you have it, the answer to why things changed comes down to economics driven by technological advances, as you and Coo have correctly noted. I'll add that for the most part, the answer to 'why did/didn't They do that' is almost always money, and the majority of the exceptions to that involve gov't actors. 'Follow the money', sure, but be careful not to stop digging down when you reach a convenient conclusion. It's never that simple.

Oh thank you for that! I was wondering what had happened

Two suns vs. One sun? 260 day years. 20 day moonths. That's still 13 moonths. Exactly 13. With no imbalances in the clockwork. The shortened moonth period creates a more powerfully luminous moon. A second sun. The great return is at hand.

Was about to comment this myself.

10 fingers +10 toes equals 20. Perhaps that’s why 20 seemed to be a logical way to break time into predictable segments. Also, 13 of those “months “does equal 260 exactly. What I would like to know more about is how those time periods corresponded with the local seasons.

Cool man please share some of these stories

These kind of comments make me barf a little everytime. It's a declaration of creative bankruptcy.

@@mathewhex7045I was about to say the same thing about your comment

@@mathewhex7045 what are you even on about

In wet tropical climate, it takes less than a decade for structures to be completely swallowed by the jungle. And while stone and earthen component will leave its mark for a very long time, wooden structure quickly disappear like it had never existed at all.

But actually rainforests are some of the most difficult ecosystems to restore when they have been clear cut because the tree roots hold so much of the nutrients and soil from erosion, that once they are removed it can take hundreds of years for the land to be reclaimed. In contrast, temperate forests are more easily regenerated because the soil is much more rich even when trees are removed, and therefore the rewilding process is much more rapid when left to restore itself.@@refindoazhar1507

Lidar

Nature abhors a vacuum.

We shouldn't be so excited with mounds. No structure remains? Maybe just a city of huts

That might be the greatest experience of your life (and congratulations to future you if you have experiences even greater). I wonder how remote the site is. It could be quite a challenge if it’s way up river in the hinterlands. You don’t want to get eaten by a wild hinter, let me tell you!

Do it!! You have decades ahead to try other things, this is spectacular! Hinters be dam'd!!

be careful with the monkeys they look cute but they are evil

@@NikoMoraKamu Believe me, I have had plenty of experience with monkeys in Brazil. I know their true intention 😂😭

@@NikoMoraKamu Just don’t touch the monkeys. Maybe they wouldn’t be so evil if you people weren’t always trying to touch them, or worse yet trying to spank the monkeys. Look, I get it. Spanking the monkey is very pleasurable. But please try and control yourself.

Ooh! ooh! Have you read Adventures in the Unknown Interior of America By Alvar Núñez Cabeza de Vaca? It's available as a free e-book if you search.

​@@flamencoprof No. But I watched the movie.

@@chacmool2581 I couldn't believe there was a movie of such an obscure book. I just looked it up, it seems a long way from the book. I'd suggest the book above it.

There's so much funny hipsterishness going on here! 😂

It’s so sad to see RU-vidrs accepting sponsorship from them again

Ngl this guy doesn't research his sponsors at all, he was promoting that scam for becoming a lord by owning land in Scotland too😂

he got a reputation??

@@BlueBirdsProductionsconverse opinion. If the content is good enough I can excuse it.

*insightful?

terra praeta?

Yes, terra preta. Its a marvel of bioengineering. Extremely advanced for its time, something equivalent to roman cement in terms of how ahead of its time it was.

Fawcett’s observations were correct but his conclusion (theosophical race-spiritualism) were indeed crackpot. For obvious reasons that stuff wasn’t in the movie and I’d venture it dissuaded a lot of people from listening (while attracting a smaller number of people).

@@SamAronow I've not seen the film and it's quite a few years since I read the book so I must admit I'd forgotten about that stuff. I mean he was quite potty, but then that sort of spiritual nonsense wasn't uncommon then and many respectable upper class types were into mediums and seances and suchlike.

Thank you for your concise presentation of the calendar and the metaphysical underpinnings that make them culturally meaningful. Excellent contribution to this discussion.

You have 20 fingers? What species are you?

@@brawndothethirstmutilator9848Digits. The original poster obviously meant we have 20 digits, which is inclusive of fingers and toes. In a lot of languages, there is not a clear distinction between the word finger or toe and you need to say something like "hand fingers" or "foot fingers" to distinguish them.

​@@eslnoob191 Russian has a word for digets. Having to specify hand or foot ones.

​@@eslnoob191 Yeah, that was the joke buddy.

Time team has some new digs up on their youtube channel, and reuploads on their time team classics channel. Also have you been watching Digging for Britain on the bbc. That has similar vibes to what time team set out to do.

It was also an illustration of civilization in contemporary society, in the sense of people being supremely civil with each other and how reassuring, indeed heartwarming, it felt. I was surprised to see that half the commenters on the YT videos mentioned this and shared how the show was saving their emotional and mental health, giving them hope for humanity! Furthermore, one of the digs had this as a specific goal beyond the historical interest. If I remember correctly, the site was a former WWII airbase and a group of soldiers with PTSD were invited along to participate with the Time Team members. It was very touching.

These fertile “dark earths”, or terra preta, may cover 150,000 square kilometres, much of it now reclaimed by rainforests.

@@flamencoprof Thank you for your response, It’s been quite awhile since I read that article and obviously there has been much more research. I’ll have to look into the subject again. Thank you once more.

@@jackdelvo2702 You could start with where I got that info: New Scientist website page: - Myth of pristine Amazon rainforest busted as old cities reappear By Fred Pearce 23 July 2015 The article mentions Gaspar de Carvajal. It has links as well.

Thanks again, read up on the current findings and it seams they added broken pottery, kitchen garbage and human waste to the porous charcoal along with the porous pottery which absorbed the nutrients and over time slowly released them into the soil. Sounds like they dumped all the settlement waste along with left over charcoal into one spot, let it “stew” for a while then spread it onto the fields. By simple observation they saw the area around their dumps had become fertile and used the mix on their fields. Kind of like observing the grass is always greener over the septic field. The addition of charcoal was the magic that made the rainforest furtile.

@@jackdelvo2702 Well researched, I didn't know about the waste and pottery aspect. We humans are nothing if not observant. IIRC they think that's how agriculture could have arisen, by observing the growth of gathered plants along the route back to camp, or some such.

WONDER since when Archaeologists started believing Scientific theories or accepting what is scientific ? According to them Humans got brains only 12000 yrs ago & Anything earlier than that , is conspiracy theory, be it science or mythology.

*some* oral tradition that was already plausible, it just lacking evidence. Let’s be fair lol, It won’t be able to prove the Inuit sun/moon incest myths, or the story of Anansi from the Ashanti, or jotün in Scandinavia.

Everything is political today. Simple appreciation or curiosity is not enough...it must be "stunning and brave!".

What do you mean by 'disruptive'? Because Lidar doesn't touch anything. It just hover over the ground and leaves everything as it was. So maybe you mean exactly the opposite: non-disruptive.

​@@telebubba5527 You must have trouble with non-literal concepts. He clearly means it's disruptive to old conventions of thought in archaeology and similar fields.

*bated breath sorry, I can’t help myself. Ignore it you wish. No criticism was implied.

It's certainly a surprize out of nowhere. The early laser spectrograph analysis could analyse plants and soil/rock. They found some plant life had a diferent color due to limestone, but limestone wasn't natural part of the soil. That's when they started finding structures/temples all over the place. They might have just as easily thrown a rock in any random direction. Lol When Lidar came out it didn't seem nearly so funtional. Great for landslide analysis/traces/history and tracking/prediction. And for ancient/current floods as well. The resolution is amazing. The space shuttle did penetrating radar scans around the earth from around 50° north to 50° south that are availible in the image files online. They've located ancient rivers, settlements even underground structures and caverns. I'd like to find the Labyrinth area in egypt to see if anything shows up. There appear to be underground rift from tomb/cavern of birds in nw. cliffs to n. side of central pyramid on Giza platou.

Mine too!

Mine too! It's crazy to realize the Amazon is no pristine land; it is a managed forest!

If they’re examining online content, by quantity I’m pretty sure they would have to conclude that we followed some type of fertility cult with all the pr0n.

😂 ​@@brawndothethirstmutilator9848

@@brawndothethirstmutilator9848 lmaooo true!!!

it is the flood plain … not forest. quoting: The area covered by lidar represented just 0.08% of the Amazon rainforest, which spans approximately 2.6 million square miles (6.7 million square kilometers). But since the extent of the Amazon is so big, we can't just fly lidar over everything.

Those urban cultures disappeared long enough ago that the Amazon forest had been given plenty of time to return to an old-growth state. And whatever lesson we take from that, the lesson is NOT that it's ok to ravage the landscape today.

Most of it was. The Amazon River Basin is immense. The evidence points to arboriculture being the dominant method of food production, not agriculture. And the agriculture that was practiced was not tilled earth row-crops.

Most of the populations appeared to be wiped out by contagious desease in the very earliest days of exploration. Many of what were considered to be natural growth trees and plants were in fact cultured food forest crops that went wild and spread across vast territory.

@@dananorth895 Disease likely played a massive role in the disappearance of these peoples, but I also hypothesize that, like several mesoamerican cultures/settlements, abandonment may be due also to excessive soil erosion due to the felling of trees in a localized areas with sensitive microclimates/biomes. The site of the great pyramids of Teotihuacan, are believed to have been abandoned for this very reason, as the vast forests that once surrounded the region, were cut down and turned to ash for mortar or used as lumber for support structures. Along with soil erosion during precipitation events, one of the side effects of this was a severe aridity subsequent to the razing of these forests.

If you double tap the right-hand side of the screen it fast forward 10 seconds. Doing this repeatedly you can skip through the advertisement rather quickly. Or if you’d prefer you can drag the red dot along the red stripe at the bottom of the video. The advertisement is even represented by its own segment, for your convenience

I wish more RU-vidrs would do their due diligence

Seems like every sponsorship is bad in one way or another. There's been so many.
