"Both spent their lives measuring the stress in stone. Both used scientific methods to answer questions that had seemed to everyone else beyond the reach of science."
Nothing, I repeat NOTHING is beyond the reach of science!
Go and investigate something that no-one investigated before, and you will find something that no-one found before.
Don't let anyone ever tell you otherwise.
Now whether [what you find] is worth the trouble of investigating (or: where one's efforts are best spent), that is another matter.
>Mark began by taking a vertical slice of, say, Chartres and replicating it in a special kind of plastic. He’d then hang fishing weights from various points on the plastic replica, like ornaments on a Christmas tree, to simulate the actual external forces acting upon various parts of the cathedral. There was the direct load of the overhead stone, of course, but also the winds. (To estimate the winds in the 12th century, he found anemometer readings in rural France going back a century. Not perfect, but good enough.) He placed his fully loaded plastic model in an oven, where it was subjected not just to heat but also light. Warmed, the plastic model revealed its stresses, sort of like the way an MRI reveals damage to soft human tissue.
>“The very words ‘statistical analysis’ seem foreign to many in rock engineering. Engineers are trained to see the world in terms of load and deformation, where failure is simply a matter of stress exceeding strength. Statistics are generally given short shrift in engineering curriculums, and so the entire language of statistics is unfamiliar. Yet statistics are the tools that science has developed to deal with uncertainty and probability, which are both at the heart of mining ground control.”
>Real-life American workers were different from his mental model of them. “I had thought if they only knew what I thought, they’d see things how I do,” he said. That idea now struck him as so obviously nuts that he didn’t bother to let them know what he thought. His fellow coal miners were less concerned with his ideas about the economy and their rightful place in it than in simply making a living. Their morale, at that moment, was actually sky-high. “Coal was booming,” said Chris. “We were going to save the world. Thank god we have all this coal so we’re not reliant on Arab oil. People felt good about themselves.”
>“A mine is unlike any man-made structure,” said Chris. “It’s not a designed environment. Most of the material the structure is made from is kind of unknown. With rock you don’t know what the engineering properties are — what the loads are. You have a problem that is really not an engineering problem, but people were insisting on using an engineering mindset to solve it.”
>Again, he found work done by others and repurposed it for his uses. Back in the 1940s, geologists working for the Agriculture Department in national forests created a crude method for work crews to determine if some rock would work as a road: whacking it with a ball-peen hammer. Oddly, it didn’t matter how hard you whacked it. There were just a handful of ways the rock might react, and its specific reaction revealed its strength. Chris started whacking mine roofs with ball-peen hammers. “It’s not precise,” he said, “but it does get you in the ballpark.”
Earth movement in general - from landslides to sinkholes to shifting foundations - is excluded from most home insurance policies.
Many non Japanese who are buying in Japan without understanding this fundamentally different aspect of real estate in Japan do so at their own risk.
I don't know specifically about mines or sinkholes, but I don't think they are generally excluded. However one difficulty would be that buildings are generally insured up to the value of the rebuilding cost, IE what it would take to put the building back after it was completely destroyed. But in the case of a mine or sinkhole, the land itself may also be unusable. In an expensive city the rebuild cost may be only a fraction of the cost of buying an equivalent home, including the land it sits on.
The issue with private insurance when it comes to natural disasters is they don't like losing money (understandable) and the climate is changing.
Those two things together mean that this year you could have good insurance that covers freak accidents, but what about next year, or next decade? An area that may have only seen flooding once a century might be predicted to see it once a decade or even once a year.
People still live there. Some people lived there with the insurance coverage for those natural disasters only to see it slowly go away or to be outright cancelled. We can't expect that they all migrate.
However, that doesn't neccesarily imply that there should be flows of money available to rebuild in vulnerable locations. Insurance becoming unavailable or unaffordable is probably the best signal available that someplace is a bad place to live. If you can't afford the price or the risk ... There are lots of other places in the world.
It's one thing to say "don't buy beach front property in the Florida everglades" but what do you do with the millions who already own such property?
This came up with hurricane Katrina and Louisiana. Multigenerational communities were completely obliterated. I really don't find "the market said you should move" to be a compelling response.
Florida existed this way for 100 yr. You have lots that had a house built in 1850, wiped out in 1900, rebuilt, wiped out in 1950, replaced with a double wide, wiped out in 2000, and then the owner gets told "sorry, build a multi million dollar house on stilts with windows rated to stop a flying patio chair and a roof you could dangle the house from or F-off"
I understand that there's a desire to stop sketchy interests from billing off "disposable" construction as "this will resist a hurricane and is prob good for 100yr" and pocketing the difference before vanishing (especially among the HN crowd because they're demographics who usually get left holding the bag) but it's not economically tenable to force communities to construct above their means either by law or by proxy with provisions written into insurance and lending requirements.
Those parts of New Orleans that never bounced back are just the denser more vertical versions of those poor Florida communities. There just isn't the money there. And while you can potentially cover this with state and federal programs (e.g. FEMA), it seems like in practice they don't quite bridge the gap.
These places are no longer safely inhabitable due to rising ocean levels. People are going to have to be relocated one way or another.
And I have no sympathy towards the "been there for generations" argument. The circumstances of your grandma just can't be a reason for what people do in the present - it s too unfair.
Chicago is a more scalable model, as both raising the city and moving existing housing worked quite well. https://en.wikipedia.org/wiki/Raising_of_Chicago
For better or worse, markets are the clearest signals we have in a hugely messy world. That shouldn't prevent us from doing the best thing available, but the world is not inherently fair and safe, and it's not possible for it to be perfectly fair and safe with our current technology and psychology.
The millions that own beach front property should accept the value of their land will decrease as it becomes harder to insure. If they don't want to lose equity, sell it sooner than later.
Built by the Spanish in 1565 and continuously occupied since then.
Should the government assist or are you of the opinion that it's just bad luck that they need to deal with on their own?
Personally I think the most rational option would be for the government to build non-profit apartment complexes across the country, but localized in areas that are projected to be safe for 100+ years where affected families could be relocated. I don't think they should be pumping money into rebuilding homes in the exact same vulnerable location though - I don't know if that's happening or not.
Normal people who've "put down roots" incur a HUGE cost when they move away from all that. Lives become optimized, you establish relationships with businesses. You make friends and engage in mutually beneficial favor trading. Ripping all that away is probably on the order of a 15-30% reduction in real income depending on the individuals in question.
I strongly believe in mandatory house insurance. We live in an area where full house insurance was mandatory and organized by the government until the 90ies. It was cheap, because it was subsidized and everybody paid in. Then they privatized the insurance, and they weren't mandatory anymore. A relative of mine realized that insurance that would cover flooding would now be nearly twice as expensive in his area as the previous mandatory insurance, so he got one which did not cover flooding. 8 years later, his house was flooded.
A few years ago, a family of 5 here became homeless because their house burned down. They did not have any insurance and lost 600,000 EUR and their place to live.
They can’t expect us to cover their losses, especially predictable and repeated losses.
When people throw money at an IPO only for it to tank we don't go around refunding them. Investments generally are NOT guaranteed, this includes assets like a house.
Should society at large be paying for someone's luxury beachfront home to be rebuilt over and over in the face of lack of insurance? Should people ignoring the climate observations and making dumb decisions NOT be penalised by losing their assets?
Honestly, there are good answers to this last question - no one wants to see an instant slums and the ongoing effects burdening society. No one wants to see grandma thrown to the curb. To be considered a society one has to act like it, which includes helping those who are down.
But not by trying to reset it back the way it was. Not by guaranteeing that people can make decisions - silly or not - with any level of guarantee.
Maybe a government buyback for property in an area that is rezoned because of climate reasons. Maybe a change in building standards to make rebuilds more reliable in the face of the new normal. Maybe public housing elsewhere to absorb the impact of such events until people can remake their lives and move on. Feel free to insert better ideas.
But the change in circumstances - in this case climate activity - has to be handled or it borders on stupidity.
Those mines still have owners, and they can be found by the state if they really, really want to find them.
Almost certainly not.
> Owning mineral rights doesn't create liability for existing mines.
I was under the impression that it generally does. However, the documents are generally old paper records (often missing) and fragmented between multiple polities in Pennsylvania. The owners of the mineral rights obviously know who they are but reconstructing the trail from public records is quite time consuming and provides a lot of "plausible deniability".
But, boy, once fracking made those mineral rights worth something, the owners sure showed up and found those "missing" records in a real hurry.
I have owned water, mineral, grazing, and other rights in the western US in environments where these were all considered valuable. YMMV.
How many houses will be made uninhabitable by subsidence in the US in the next 5 years? I predict more than 100 and fewer than one million. There, that's a prediction. A team of actuaries armed with historic data could massively improve it.
This is much easier than the same kind of prediction for earthquakes or hurricanes, which have tail risk of unlikely but devastating events. If insurers don't want to cover this kind of risk, it's either because it's too small to be worth spending time on, or so predictable that it's not worth spreading the risk (better to just condemn the handful of houses built on top of known mines and move on).
Sort of an IRL Hell.
The entire Ruhrpott settled and sank so much that if the water pumps in the largest mines would cease operating for too long, the entire area would flood. It's literally called "Ewigkeitslasten" (forever burdens) for that reason.
I do appreciate creators who give us a real website alternative, not just drop videos on <centralized platform>. Everyday Astronaut is another great one.
For me, I do it because I like writing more than I like making videos, and I know many people appreciate it.
But my blog maybe makes a few pennies a month, whereas my video content provides my full-time income.
So I'm not surprised most content creators who can, move to video-only. It's only out of passion for the written form/blogging that I still do my text posts :(
