If you go back into the Brexit thread, earlier this year it was claimed that the blame for the British domination of Ireland should be laid at the French's door. And possibly the Pope, too.

It's not wrong.
France is the Pope's fault because Charlemagne and somesuch, and then some French king gave Normandy to the Normans, and then the Normans took over England and wanted to have Ireland too.
 
So ultimately it'd all be better if everybody had stayed under the spiritual authority of the Patriarch in Constantinople, under the tutelage of the vicegerent of God on Earth. Nice.
 
I learn something really weird and coincidental today at the office. I listen to youtube while working, I was listening RATM "wake up" just for nostalgia, then it keep rolling until it arrives to the song called "sleep now in the fire", I click the tab and watch the middle of the video, and I notice that within the crowd there is a man holding up a sign "Trump for president 2000", and I cannot believe what I see. I recheck again from wikipedia the song is released in 1999, and how can he predict, base on what logic or information that he preditcs trump will be a possible candidate, that's a complete madness for me. Like he predict all this thing will be happened like nearly 20 years ago.

Searching on google, I found an article about RATM prediction, but I haven't read it yet. This is really mind blowing for me.

TIL that it is not the force from size and duration of the tectonic collision that dominates the formation of high mountains, but the latitude of the location.
This explains why the highest mountains are near the equator.

When the tectonic collision is as such strong enough to generate mountain growth during the duration of the collision, it is the amount of erosion that determines how high the mountains will become.
Because the erosion of ice and glaciers is much stronger than normal erosion from weather, the snowline of the mountain, which depends on the latitude, becomes important.
As a rough rule of thumb the typical max height of mountains is 1,500 meter higher than the snowline.

At low latitudes, the atmosphere is warm and the snowline is high. "Around the equator, the snowline is about 5,500m at its highest so mountains get up to 7,000m," said Egholm. "There are a few exceptions [that are higher], such as Everest, but extremely few. When you then go to Canada or Chile, the snowline altitude is around 1,000m, so the mountains are around 2.5km."
"What we show is that, once the mountain is pushed up across the snow line, a very effective erosion agent comes into play and that is represented by glaciers," said Egholm. "It's so effective that it can keep pace with any tectonic uplift rate that we have on the Earth today." Below the snowline, rivers and rock falls are the main erosion agents.

Denali is 6190meters and north of the Arctic Circle...

yes
What makes Denali special is that it is made up out of granite, which is much stronger than normal rock
Granite is formed from slow cooled magma under the ground. When this is moved up again from tectonic processes you get mountains with granite, instead of the more usual mountains with normal rock.

Probably not better, but it wouldn't be the Pope's fault. It would be the Patriarch's fault.

The term is 'metamorphic'. And by normal rock you probably mean 'Igneous'.
TiL granite is a metamorphic rock.

:mischief: :)
 
Oops. :lol:

Then Granite IS 'normal rock'.

My knowledge on rocks and granite before that TIL post was limited to one nice documentary on the Alps where was explained that the Alps were mostly made out of stone, rock and for a smaller part out of some granite slabs, like a big part of the highest mountain the Mont Blanc, that are much harder. And granite needs to have been melted before. Most of the Alps is just a pile of stone rubble.

So I digged in a bit and learned a lot more
To that "Granite IS normal rock":
No
Rock is nothing else than a solid agregate of minerals.
When that is pushed down by a tectonic movement where it can melt to magma and slowly solidify again it becomes intrusive igneous rock and is stronger than the original rock because of the recrystallisation. When that original rock contained a lot of quartz and feldspar, you can really call it Granite, because of the hardness. If magma cools fast it becomes extrusive igneous rock, also called basalt, that has smaller crystals.
Also the Himalaya is a combination of granite and softer rocks like limestone (sedimentary rock from chalk from microorganisms from the seabottom) and gneiss. Gneis is rock compressed at >600 C temperatures, that did not melt.
Hardness goes roughly by: granite > gneiss > normal rock > limestone and other sediments.
If you have ever been at the Niagara waterfalls you can also nicely see how hard rock and soft rock are intermingled. The top layer of the ground is hard rock and below softer rock: when the softer rock is eroded, is splashed away under the harder rock at the point of the waterfall, the harder rock has no support anymore and breaks off. By this process the waterfalls move upstream over time with downstream the canyon.
Here a nice picture of granite and gneiss of one of the tops of the the Mont Blanc massif, where you can see the granite slab marked.

Igneous: Volcanic in origin
Sedimentary: Sediments of various types laid down in layers often at the bottom of oceans
Metamorphic: Rocks created from high temperature and pressure deep in the earth

Rocks you find fall into one of those categories.

So that's why my socks smell of curry and my curry tastes of socks!
 
I can honestly say, that I have not.
