Why We Froze The Leaning Tower of Pisa

- The Leaning Tower of Pisa has been in the process of falling over for the last 800 years. How engineers have prevented it from collapsing teaches us about modern buildings and the future of land reclamation.

This guy has contacts, getting laboratories everywhere he goes.

This channel is a treasure trove, gotta thank Tom for bringing me here
Fun-fact: that’s how Venice was (and still is obv) built. On logs pushed into the wet/murky soil-water. A whole city of cathedrals and marble on sticks in water
This is the one and only perfect demonstration/educative video i have ever been recommended. Good job fellow INTJ.
Here in the Netherlands the pylons don't go until the bedrock but just far in to the clay. The actual bedrock is just to far deep to ever be off use.
Here the pylons are the foundations as they them selves create the stability.
This is an excerpt from an excellent NOVA doco on the Pisa Bell tower:
"1995
After deciding to replace the unsightly lead counterweights with an anchored cable system, the Pisa Commission begins freezing the ground with liquid nitrogen in preparation for installing the cables. As soon as the freezing stops, however, the tower begins to lean south at a rate of four arc seconds per day. This begins in the middle of a September night, which Commission members will come to remember as "Black September." The operation is immediately halted, and the search for a permanent solution continues with new urgency."
The final solution that stabilised the tower used a soil extraction technique.
Amazing once again! Keep looking up!
I can't help but think that you dubbed your self. Other than that in the back of my mind, informative!
Unfortunately most of the audio got corrupted on the Europe trip so did have to dub unfrotunately. On the plus side I've been getting better at it so more recent ones are ok. Thanks!
@@AtomicFrontier You were better than a BBC documentary on Tom Scott so I'd say your recent stuff is amazing for sure! 😊❤️
Great video. I find, when on study breaks, these videos excellent for absorbing information
I knew I recognised that library in the intro, was going to comment asking if it was uni of leeds
Excellent! Hello, Redditors. AtomicFrontier has made us proud.
Nice! 1:19 Thermo fisher box lol i work for them!
hmm - I wondered if they could have leveled the tower by progressively freezing from the one side and not the other until it leveled out - they probably didn't want to make it level given the fame of having a leaning tower, but would it have worked or would the change in loading on the tower actually cause more problems?
As someone who went to school for drafting I have never seen an Autocad book that thick in my life.
Keep looking up!
I understand that freezing the ground will stop the tower from moving, but for how can you keep this up? It seems like a very expensive way of problem solving.
Hi Horst. Yes, you're right. It was only ever intended as a temporary solution while they installed better supports. They couldn't do this with the ground in its normal soft form as moving heavy machinery might have dislodged the tower and make it fall prematurely.
Great video James!!
Thanks Annabel, glad you enjoyed it!
Nice video! Learnt a lot from it
Wow...this was amazing. Thanks for breaking these down for the non-scientists
3:55: "Let's head to the lab to see if that would actually work."
Didn't you kinda spoil the answer by showing the Leaning Tower of Pisa still in one piece?
Such great work man!
Great video, man! May I suggest you use a fade out with your audio clips so it gives it a little more of a smooth transition. Other than that, I thought it was very informative and well presented!
Thanks Bill! Will do that in the future :)
can you add al the videos into a playlist
Great video 👍...thank you for support me 🙏🏿❤
We missed the train to Florence because we had to adjust the time by one hour. So we bought a replica 🥰😍🤣
Wouldn't dismantling the tower, building a proper foundation, and reassembling the tower provide a permanent solution? The new foundation could even be canted so the tourism value could be preserved.

littarly every building in the netherlands ;p
Wait this guy gets labs, and he only has 129k subs?
This guy shows up in a lab and films until security kicks him out :)
@@AtomicFrontier lmao
But seriously youre underatted, unless youre like popular somewhere else and this is a side thing
i thought soil extraction helped save Pisa tower.
See, this is why pizza was meant to be flat! First it's deep dish, and next it's towers of pizza so large that they require expensive engineering projects just to keep from falling over!
no
idea we have never

The real tower of Babylon, just like switzland was once Australia. 7even levels seven stars tower is
Imagine if global warming melts the frozen sand and the tower collapses-
