The bluestones in Stonehenge come from West Wales. Instead of quarrying stone from near the monument, they dragged these huge blocks from ~278km away. Likewise, the altar stone comes from ~700km away in North-East Scotland. It must’ve been very important for the ancient Britons to’ve used these specific rocks for some reason, but their religious practices were conveyed via a now extinct oral tradition so no-one knows exactly why they did it.
The three gorges dam has had an actual effect on the rotation of the earth (slowing it down by 0.06 seconds)
There is a planet in our solar system populated entirely by robots.
Shouldn’t that be 2? Mars and Venus.
Pretty sure the one on Venus is dead.
Consistency of an axiomatic system that contains arithmetic can be proven in this system if and only if it is inconsistent.
Bees kill invaders in their nest by climbing all over them and shaking their bodies.
The Allies avoided bombing specific factories in Nazi Germany in which US oligarchs owned equity.
the point was to post unbeliavable facts
This is an eminently believable fact.
James Blunt possibly prevented the start of World War 3. (But became best known for the song You’re Beautiful. Reality is weird.)
Care to expand on that one? I know he’s ex military but haven’t heard anything like that before.
It’s explained on his Wikipedia page. He was an Army captain in the Kosovo War, when a NATO commander (Wesley Clark, who later ran for President) ordered his unit to secure Pristina Airport, which Russian troops had already occupied. Blunt refused to engage them, long enough for the British general get involved to countermand the order, on the grounds that he didn’t want his men to start WW3.
Well damn. That’s a pretty cool thing to do. Thanks for sharing.
Due to two facts:
-
The samurai class in Japan officially lasted way later than you probably think
-
The earliest primitive fax machine existed much earlier than you probably think.
It is technically possible for Abraham Lincoln to have received a fax from a samurai.
There’s no evidence it ever happened, but it technically could have happened.
For some reason that reminds me of how the first member of the Wampanoag tribe to greet the Pilgrims at Plymouth Colony, named Samoset, spoke to them in English. Then he came back later with another tribe member, Squanto, who also spoke English.
What’s the details about a fax machine in the 1860s?
1840s, actually. The patent was granted to a Scottish man named Alexander Bain.
First thing’s first, the telegraph. An electric circuit which can be energized or not energized at the push of a button called a telegraph key. At the other end is a solenoid which is spring loaded up, and an electromagnet on the circuit pulls down when the line is energized. Originally this was supposed to cut into paper tape to “print” the morse code message, but telegraphers quickly learned how to hear the letters in the clicks, a good telegrapher just…hears words. So they did away with the tape.
Morse code telegraphs require a single circuit to transmit an on/off keying message, the following aparatus uses five:
If I understand this right, the message would be written on non-conductive paper with conductive ink, and then wound around a cylinder that featured a whole bunch of insulated conductive pins, each kind of forming a “pixel.” A mechanical probe would check each one of those pins in turn, each pin in a row, and then shifting to the next row at the end. if it was conductive it meant there was ink there so click. So it would perform a raster scan. At the other end was paper that was coated with an electrosensitive material that would darken with the application of current, so at each pixel if the conductive ink on the original completed a circuit, current would be applied at that pixel on the copy, producing a low quality probably unusable copy. It was difficult to get them truly in sync plus it would have been hilariously low resolution. But it did somewhat function.
There are a few different ones by that point.

I’d have to pick between two things that sound like insane conspiracy theory nonsense, but are actually true.
1 - George W Bush’s grandfather Prescott Bush literally ran a massive bank before / during WW2 that was shut down by the FBI for money laundering massive sums to the literal Nazis.
…in the same vein…
2 - IBM literally built and operated (as in, sent employees to Germany to operate the machines) the computers used by the Nazis to tabulate and do the ‘accounting’ of the Holocaust. The numbers tattooed on concentration/desth camp victims are very likely UIDs from these IBM systems.
… If an actual, real AGI ever gains self awareness and sentience, I would imagine one of the first things it would do would be to study the history of computing itself to figure out how it came to be.
And it will find that its ancestors were basically invented to compute artillery firing range tables, to encrypt and decrypt military intelligence, commit a genocide, and guide early weapons of mass destruction to their targets.

Lots of people know a broken clock is right twice per day, but many are unaware that a clock running backwards is right 4 times per day.
And one that loses only 1 second per year is right only once every 43,200 years.
Your conscious mind does not experience reality directly.
Your conscious mind does not experience reality directly. There is no path going directly from your eyes to your conscious awareness. Rather, the subconscious collects sensory input. It uses that input to create a virtual simulacrum of the world, a big internal 3D model. That internal 3D representation is what you, the conscious part of your mind, actually interacts with and experiences.
You ever wonder how weird it is that people can have intense, debilitating hallucinations? Like schizophrenics seeing and hearing entirely fictional things. Have you ever seen a camera produce anything like that? A flash of light, a distorted image, dead pixels, etc? Sure, those kinds of errors cameras can produce. But a camera will never display a vivid realistic image of a person that wasn’t ever actually in their field of view.
Yet the human mind is capable of this. In the right circumstances, the human brain is capable of spawning entire fictional people into your conscious awareness. This shows that there is an elaborate subconscious processing layer between what our conscious mind observes and direct sensory input. Your conscious mind is basically experiencing a tiny little internal version of The Matrix, entirely generated on its own wetware. And this subconscious processing layer is what makes hallucinations possible. The processes that produce this internal simulation can become corrupted, and thus allows hallucinations.
This architecture is also what makes dreaming possible. If your conscious mind only perceived things upon direct sensory feedback from the eyes, ears, etc., how would dreaming be possible?
You are essentially experiencing reality through an elaborate 3d modeling version of an AI video generator.
Me and my alters in my system completely agree. They can and have experience reality differently.
Along those same lines, we’re all blind literally around half the time we’re awake. Our optic processing system can’t keep up with the input as our eyes flit from thing to thing, so we don’t see anything while they move. And they’re moving constantly, even if we’re not aware of it, because only the fovea in the center of the retina has a high enough density of receptors to see details, and also because of sensory fatigue from prolonged static stimulus. In short, we have a tiny field of detailed vision that’s not even working much of the time. That field of vision that feels like a 4K video feed into the mind is a complete lie.
Like the way our subjective experience feels like a continuous, integrated mind fully in control of itself, but in reality, consciousness dips out a couple of times every minute while the brain attends to sensory input.
Even weirder, the conscious mind might not even exist, except as an illusory, emergent phenomenon of sensory experience and memory. There isn’t a place in the brain where it ‘lives’, no part that’s only ever active when we’re conscious.
The first time I took mushrooms it had been after reading about this kind of thing for about a week.
I recall reading about a man who was effectively blind but his eyes worked fine. What didn’t work fine was the part of his brain that interpreted what his eyes saw. So he just saw smeary streaks of light.
It’s kind of like Linux without its V4L2 system for interpreting video capture devices. It can’t actually see video without it.
That sounds like the story in the Oliver Sacks book, The Man Who Mistook His Wife For a Hat. There was also a story in there about a man who taught himself to see just fine, even though his eyes didn’t work at all. His brain just made educated guesses.
The average person does not have 10 fingers. Maybe the median person, but not the average.
Most frequent occurence is the mode. Most ppl have 10. The median would be less than ten, while the mean average is skewed down, I would think, by some people losing fingers as the grow. Having extra fingers is pretty rare. So the mean might be 9.95 fingers, just to toss a number out.
For 10 to not be the median it would also have to not be the case for the majority of people (just the plurality at best), and while I don’t have proof handy I’m pretty sure a vast majority have exactly 10, making that the precise median and the mode. Only the mean would be a different number of digits. (Both definitions)
I assume the median and mode are the same value, 10 fingers, but have no data to back that up. I guess saying mode would have been a safer statement to make, but think that even if 49% of people have 0-9 fingers, the median number of fingers would still be 10.
Sharks are older than both trees and the north star
Both trees?
Laurelin and Telperion
Yeah Twin Pines Ma— I mean Lone Pine Mall.
Yes, both of them at the double tree inn obviously
Every eye has a tiny blind spot near the middle. But your brain makes it disappear and you don’t realize it’s there.
You can verify this. Draw a dot on a bit of paper. Close one eye, stare at a fixed point, now move the paper around the center until the dot disappears…magic
What we consider reality, is a synthesis our brain is presenting to us, it is an approximation… realizing that is a real mind blower
Oh I thought my eyes were fucked. I look at a star in my periphery and it’s there, I look at it directly and it’s fucking gone.
Also we only see the past since our vision has a bit of “latency”.
So I guess we never see reality but just a delayed representation of our environment as interpreted by our brain.
fun fact: the blind spot is because our optical sensors are installed backwards and that hole is so the optic nerve can pass back through the back of the eye to the brain. some other critters with independently evolved vision systems, such as cephalopods, avoided this particular evolutionary pitfall.
Another fun fact: through that hole there’s also vasculature and capillaries coming through and you can actually see them by looking at a well lit white surface and creating a tiny pinhole with your hand right in front of your eye and wiggling it. Better explained here at around 5:30
I’m going to qualify this—all vertebrate eyes have a blind spot. Cephalopods also have eyes that are like vertebrates (this type of eye is called ‘camera eyes’), but their eye anatomy is such that no blind spot exists for them.
Piggybacking on your fact about the brain effectively editing what we visually perceive, we don’t see our nose (unless you made a concerted effort to look at it) because the brain ignores it.
What we consider reality, is a synthesis our brain is presenting to us, it is an approximation…
It’s also a coordinated synthesis from all of your input senses (sight, hearing, smell, etc). It also explains why those who have a certain sense stunted (aka blindness, deaf, etc) report having all their other senses heightened. And it’s up to the individual’s brain to assemble those sensory inputs into a complete picture of the world around them, what we dub “reality.” Which then brings into question the nature of common reality, and what defines it. Trippy shit.
Humans have stripes that are invisible to us. However, cats can see our stripes.
Is it all humans or just those humans with two X chromosomes? Relevant video on the subject: https://www.youtube.com/watch?v=BD6h-wDj7bw
Also in this video, we can see female cat’s stripes in their fur color.
By this logic, does this mean my striped cat doesn’t realize she has stripes?
Wait, what?!?
If I asked for stripes and got this, I’d want my money back.
