As people here work in various jobs / professions they might know things from work or study no one here knows yet. this is what this topic is about.

what do you know that we have never heard of?

Eg: you don't need to be great at maths to be an architect

this is obvious to me but everyone says to me "i wanted to be an architect but i was bad at math,i can barely add"

We, along with pretty much all other life on earth except for bacteria are formed by eukaryotic cells. Bacteria are prokaryotic. There are a few differences, but basically the genetic material of prokaryotic cells just lies about in the cytoplasm of the cell instead of being enclosed in a nucleus like in eukaryotic cells.

The theory goes that way back when, our ancestor, a eukaryotic single celled organism, engulfed a prokaryotic cell, but instead of that cell being consumed like normally happened, the prokaryotic cell remained and eventually evolved to become the mitochondrion. Hence, why mitochondria have their own DNA, separate to the DNA in the nucleus.

VERY simplified version, but that's the gist of it.

Same thing happened to plants.

Chloroplasts in plant cells that do the whole light to energy thing are descended from engulfed bacteria too.

There's a non canon Star Wars comic called Into the Great Unknown where Han Solo and Chewbacca crash into Earth after using Hyperspace blindly. Han is killed by Native Americans and his skeleton is discovered by Indiana Jones 126 years later while Jones is searching for Sasquatch which turns out to be Chewbacca.

Probably not as interesting as this Polish lad but I've heard a pretty interesting podcast about two young mountaineers that wanted to attempt climbing up an ice wall in the Karakorum mountain range (I forgot the name of the mountain they wanted to summit) and if they'd succeed they'd be the first successful ones. They talked a lot about the process of preparing themselves for it.
Up until then I never realized how this isn't a hobby but this is your life doing it.

Anyway, their training and preparation consist of travelling to the area months before, living on a high altitude with some locals in a village that's still in the middle ages really and from there they go daily tours to get used to the climate and conditions. Once the time is right, they have one attempt because there apparently is only a small time gap they have to try.
The wall has an approximate height of 2000m and when asked how long it would take them they said anywhere between 5 and 7 days, depending on conditions. It's crazy to think it would take them that long. Plus 2-3 additional days to summit.

I unfortunately never found out if they made it or not, I'll search the depths of Google later.

K2, on the Pakistan-China border, is the second-highest mountain in the world. 21% of people attempting to climb the mountain have died in the process, second only to Annapura I (32%!).

It is the only 8000+ ft mountain never to have been climbed in winter (out of 14). This hard bastard is currently attempting it:

Krzysztof Wielicki, Polish, he's now 68 years old. He made the first winter climb of Everest 38 years ago, along with 2 others of the other 8000+ ft mountains, and he's still going. Best of luck...

Would equilibrioception include the sensation when you’re reversing into a car parking space, stop and the car next to you pulls out slowly making you think you’re reversing again so you slam on the brakes? :rolleyes:

I'm pretty sure that's what happens when your equilibrioception gets confused

A few years ago I pulled into a parking space just as the two cars either side decided to pull out, at the same rate. I was completely disoriented, stood on the brakes and wondered why I wasn't moving and why I was moving at the same time. It played havoc with my perception.

Happened me only yesterday, was stopped in traffic when a truck beside me started to inch forward I panicked and slammed on the brake thinking I was rolling back.
This was on the naas road, not some dirt track half way up the andes, it's not like I would have tumbled to my death, but it did give me quite a fright for a second.
In my defence it was early morning, I was still on auto pilot!

Infections can cause abyrinthitis or vestibular neuritis, where the nerves become inflamed and that affects the signals travelling to the brain. That faulty signal results in the lack of coordination and problematic spatial perception, and you simply can't move or perceive movement in the same way.

I've never had anything like it, but my mother had viral vertigo a few years ago and found the disorientation really difficult to deal with.

I hope it's something I never experience.

Was actually driving when it happened so yeah pretty scary. Somehow managed to pull over but I was too disorientated to use the phone to call anyone. Thankfully a good samaritan was passing by and called for help.

The effect only lasted a few hours but even so it wasn't fun.

One of the less familiar of our many senses is the sense of equilibrioception, which helps our perception of how fast or slow our bodies move and in what way, and helps us factor in things like gravity in our movements and balance.

This sense is guided by the vestibular labyrinthine sensory system in your inner ear and when it's not working as it should - usually when inflammation from infection interferes with the communication of information between the sensory system and the brain - it can cause all kinds of issues with perception of direction or movement, vertigo, balance and even visual disturbance.

Instead of having good balance, you could say that someone has a good sense of equilibrioception, though it doesn't have the same ring to it.

Another interesting sense we take for granted is the sense of proprioception, which tells us what all our individual body parts are doing, and where they are relative to each other. So we can change the gear with one hand and depress the clutch with our foot and steer with the other hand all at the same time in reasonable co-ordination, or I can put my earring in the piercing in my ear without having to figure out where either my ear or the piercing through it is. If you have an itchy nose, your sense of proprioception will guide your hand directly to your nose without you having to locate your nose in a mirror to guide your hand.

Drugs and alcohol affect your sense of proprioception, which is why you may poke your eye out while trying to scratch your chin, stagger or fall asleep upside down if you're a bit of a lush.

at the time the CEO said he wouldn't care if Real Christians boycotted his products, as there weren't enough real christians left to affect sales.

At the end of the American Civil War, tens of thousands of southerners moved south to Brazil to begin again. Most moved south the the state of Sao Paulo but one group, led by Major Lansford Hastings decided to move north into the Amazon Jungle.

Lansford was granted a tract of land 259,000 acres for which he had to pay 22.5c/acre for at the end of 3 years.

Sadly, he died after one year of Yellow fever but their presence there began the process of understanding the history of indigenous cultures that had lived there before them.

I've included a link, from which I stole all the above, giving a bit of a history of th above.

I can't believe you didn't quite this bit.

One Confederate, Romulus J. Rhome, operated a large sugar cane plantation on such a terra preta site and took an interest in the abundance of archaeological artifacts that were buried in the soil.

That's one hell of a name.

While we're on the subject of 'poo' and intestine bacteria....

My Mrs is not allowed use hand sanitisers in here job as a carer. Hot soapy water only. Using hand sanitisers continuously for long periods drops the level of bacteria going into your mouth (and therefor intestine) to dangerous levels. What's the best way to recoup your bacteria if it's dangerously low I hear you ask??? Well, it's through a poo transplant of course, also know as a Fecal microbiota transplant. It's basically a tube down your nose and someone else's healthy, bacteria ridden, poo is pushed down. As we all have a different concoction of bacteria, the implant must come from someone very close to you, eg. lives in the same house. It's an extremely successful treatment apparently but it's enough to turn your stomach!

Vice did a segment on poo transplants. Worth a watch if youre into that sort of thing.

Slightly related - I was reading a thing the other day about household hygiene (as you do!). Basically the only substance known that comes even close to housing the same concentrations of bacteria as excrement, is your kitchen sponge. Let it build up for a few weeks and weight for weight it can house much the same concentration of bacteria as shít! :eek:

You shouldn't try to disinfect it, that will likely only make matters worse, you should just bin and replace it regularly (every week or so).

There are about 3500 different species of bacteria within that 2.5KG and you would die without them.
