No Stupid Questions@lemmy.world•Where did the abbreviation "w/" for "with" come from?
2·2 years agoYeah. I have no evidence that this system invented those shortcuts, they may predate it by quite a bit
When we allow aparthied states to comnit genocidal acts without protest, we signal that other countries should not interfere should our own state turn to aparthied and genocide.
Its either ok for no one or its ok for everyone

8·2 years agoIn the Speedwriting shorthand system, developed in 1924 for use with typewriter, / Is used to denote omitted sylables, so ‘with’ becomes w/ and ‘without’ becomes w/o. Here is a pretty deep guide on the precepts of Speedwriting:

But yeah, thats a big pressure away form it and a reason its still daydreams

United Kingdom@feddit.uk•Cockney and Queen's English have all but disappeared among young people – here's what's replaced themEnglish
10·2 years agoThis is just another study confirming what has been known for years. MLE is the multicultural expansion of cockney. Much of the accent survives, but has been modified by exposure to many cultures. Its been identified as the dominant native london accent foresomething like a decade.

Interesting Shares@lemmy.zip•Scientists Successfully Simulate Backward Time Travel with a 25% Chance of Actually Changing the PastEnglish
651·2 years agoOk, so, this is in the context of closed timelike curves. This is a thing which appears in the math of general relativity. It has never been observed in real life, and may disappear if we ever have a reconciliatian of quantum mechanics and gravity.
The study was a computer simulation of “what if we had some particles in a closed timelike curve and could mess with them”, and there is no suggestion of this being applicable or even possible in the real world.

7·2 years agoMountain bases can support a lot. Everest is not terribly tall from its base, true, but Denali is 5500 meters from base to top and Mauna Kea rises to 10000 meters over base.
Its also a bit of an incorrect picure to think of the interior magma as a liquid. It can flow, but it can also sieze up or crack. Its an in-between, like corn starch and water.

9·2 years agoWhat we see now are the ancient roots. Before the continental colision, there was a sea and subduction zone. This gave us sandstones, diorite, and granite… All of which were crushed at incredible pressure and temperature by the continental collision. At the deep roots of the mountains, this transformed the rock into gneiss, marble, and other extremely hard rock. Additionally, the forces were so great that the very bottom melted and became fresh granite.
All of these stones are very hard and resistant to erosion, and are what we see todayas the Appalachians

6·2 years agoIts indirectly gravity. The taller the mountain, the more eroding force can be pleced on it. Water travels faster and therefore cuts deeper.
Everest is still uplifting fairly quickly at 1mm a year, but its also eroding at roughly the same pace and won’t get significantly taller than it is now. The same is true for the rest of the Himalaya as well, the whole range is eroding at a very high pace.
The Himalaya are home to some very spectacular canyons, including the largest canyon above water. The geology there is on full display and incredible.

11·2 years agoI have started daydreaming of a career change to geology. There are just so many unanswered questions and its not like space or physics were these questions are tinyor super far away. You can just walk upto a geologic puzzle and hit it with a hammer.

17·2 years agoOne nit, pangea wasn’t the first supercontinent, we know of at least two, maybe three before it. The stone of the Adirondak mountains was formed as part of the Grenville mountains, which were built by a suprecontinent 1.5 billion years ago (the adirondaks got tall be’ause of a much more recent, unrelated thing, but their stone is very old). The Grenville runs from Hudson Bay to Texas

10·2 years agoCompletely unrelated. North and south america wern’t attached when the appalachians were tall. The Andes are formed by an ocean plate (the Nazca plate) dragging as it is sucked under south america. They are tall, and still growing taller.

16·2 years agoThis is because thats basically the upper limit for how tall a mountain can be on this planet.







So, this dating is extremely controversial. The single researcher who claims it has not yet published those findings, and the dates vary wildly (from 9,000bp to 20,000 bp) from interview to interview. No material culture has been found at the site suporting dates older than 2,000bp. No source culture for the 9,000 to 20,000 date has been identified.
Enen if the dating is verified at somewhere inthat range, all it demonstrates is that something was at the site at that time (if the dating material is from a fire, it shows someone lit a fire there, for instance). Considering there were tool-making hominids in Sundaland 1.5 million years ago, and homo sapians 45,000 bp, it would be interesting, but not revolutionary, to find some presence at the site. Much more and varied evidence would be required to indicate that this was a megalithic work predating Gobekli Tepe.
As a second note, also important: Gunung Padang is not a pyramid. Its an andesite hill which naturally fractures in to columns and terraces. Some of the terraces have been leveled off by trimming and filling, but that is a very different task from transporting stone to build a pyramid or other free-standing megalithic structure.
