Please teach me obscure science facts

noice, I will spread this, is it true though?

Quantum skeletons are real.

Quantum dancing skeletons are also real.

Well memed my friend.

What a fucking retard, do your research

Here's your (((you)))

Progeria is an incredibly rare genetic disease, occurring in one per 8 million kids from birth. As its name suggests, the kids who suffer from this disease show symptoms characteristic of very old age, as if they were born elderly. The disease is caused by a point mutation of the LMNA gene, which, put very simply, causes the gene to generate a truncated (i.e. abnormally shortened) version of the original protein.

There are many symptoms that the kids show. Low weight or inability to gain weight is typical, as is scleroderma, stunted growth, full body hair loss, wrinkled skin, atherosclerosis, eyesight problems, kidney failure, arthritis, degenerating muscles and joints and other symptoms generally exhibited by very old people. Mental capacity seems to be the same as normal kids of that age, however.

The vast majority of the kids suffering by this condition never make it past 13 years of age. The disease is incurable.

no.

Impossible.

Contrary to other acids, hydrofluoric acid in moderately high concentration (5-50 % volume) doesn't burn right away when in contact with the skin. This liquid, not realy distinguishable from water, destroy the nerves quicker than the pain signal can reach the brain, preventing the victim to feel a chemical burn. The fuorine ions permeate easily the skin and reach the bones and blood, forming strong bonds with calcium. No symptoms are felt before 6 to 8 hours after exposure, when the skin starts to look burnt and bleached, and horrendous pain starts as the bones gets eaten by fluorine. The main cause of death is heart attack from lack of calcium ions in the blood. An exposure the size of a palm, if untreated, is lethal within 12 hours.

>pic related : the tv show is full of shit when dealing with HF.

source : I work with that shit everyday.

Aposthia is a rare congenital defect in which a male child is born circumcised, born without a foreskin. Moses and Mohammed supposedly suffered from this condition, if suffer is the right word here.

>Events happen slower in increased gravity
Sooooo . . As we go back towards the initial singularity the universe gets denser and denser and therefore gravity gets more and more intense and time slows and slows.So when we estimate 13.7 b.y. for the age of the universe we do it by linear extrapolation from current conditions, while in reality it is timeless and there was no "beginning". A bit like asymptotically approaching absolute zero.

>if suffer is the right word here
Yes it is.

Whoa

Fits with a story I was told when I worked for a chemical process industry contractor years ago. A guy standing under a slow leak of HF catalyst in an alkylation plant had it drip on the back of his neck and didn't notice because the nerves were being destroyed. It killed him, though not immediately.

>universe gets denser and denser and therefore gravity gets more and more intense and time slows and slows

That is interesting/

>while in reality it is timeless and there was no "beginning".

Yes, and no.
Personally I don't believe there is a beginning. I believe all matter has always existed, and always will, but it is only our perspective in time that allows us to see the Universe in separate parts.

I try to use the kinked rope as an example. The rope, is a whole, but the kink being the bubble of time in which we view materials separated as individual parts. It is all still connected, it never really completely broke apart. The Universe is beginning, already here, and recombining all at the same, but only in our view we're allowed to see it spread out as individual pieces.

When objects fly through space close to earth they speed up more than they should and no one knows why

In the southern hemisphere, you have to throw frisbees upside down.

Posting from New Zealand, can confirm

I don't know if this is really obscure but it was mind blowing when I for the first time encountered it:
Quantum Mechanics, realism and localism cannot be all together correct. You have to give up localism or realism if you want to work with QM.

Because the universe is 4-dimensional and there was never a single point at which the universe could be said to have begun, and because gravity, along with the other fundamental forces, had extremely fucked up effects early in the universe, that's wrong. Pretty interesting theory though.

So if we posit that the four dimensions can be treated alike as per Einstein and then we say that there was never a single (spatial) point at which the universe could be said to have begun then . . .

you can ring a metal bell by gently touching it with dry ice

doesn't work with normal ice though

I'm not a physicist or even a scientist, but I once read a proposition that the emergence of matter, EM radiation and the forces of nature that we recognise today are the result of spontaneous symmetry breaking as the temperature(energy density) of the universe dropped. The proposition was that "nothing", i.e. not a vacuum, not even space/time, was too perfect (symmetrical), and just had to break. Hence the universe. Also, confirmation of my long-held suspicion that Murphy's Law is the primal principle from which all other laws of nature are derived.

same reason quarters flip shit when stuck into dry ice i assume?

Virtual particles are particles that come into existence and fade away so quickly they don't have time to interact with anything in this universe. At any given time virtual particles may come into existence as complex molecules or any and every possible combination in any and every possible place. In fact, a collection of virtual particles forming a spooky skeleton just appeared right behind you right now!!! He will have dissipated before you can turn around tho.

Spooky

In superconducting materials, is possible for electrons (fermions) to behave more like photons (bosons), and are called cooper pairs. These cooper pair electrons have unique properties:
>The electrons are able to all occupy the same space (energy level) at the same time, violating the fundamental pauli exclusion principle for fermions, which is why chemistry even exists.

>Cooper pair electrons conduct electricity with infinite current (zero resistance), which theoretically will cause current to flow through the material without an energy source, forever. The electrons have zero resistance because they are energetically forbidden from colliding (with other electrons, atoms, and anything else). The energy imparted by colliding is not enough to break the cooper pair "bond", which is equivalent to breaking all cooper pair bonds in the material at the same time, and so they do not collide.

>Magnetic fields are carried out of the material by these cooper electrons (Meissner effect) as it cools below its critical temperature and becomes superconducting, which causes it to spontaneously levitate over a permanent magnet.

>They are working on developing new superconductors which possibly do not utilize cooper pairs, and ones that can operate at higher temperatures, with the ultimate goal of achieving room temperature superconductance. Here is a nice list of the revolutionary benefits of achieving this goal (it still has limitations). reddit.com/r/askscience/comments/1hp8wo/what_would_be_the_effects_of_creating_a_room/

Some downsides of superconductors include:
>They generally have to operate at very low temperatures (mostly less than 80K), because vibrations have enough energy to break cooper pair bonds.

>They have a critical field strength, which scales inversely with temperature, so the closer to 0K the better, regardless of
their actual critical temperature. Magnetic fields begin to penetrate the material and break apart the cooper pairs.

John von Neumann (1903-1957) is believed to be the smartest person to ever live.

He possessed these characteristics:
+ 100% neurotypical, no autism/assburger/spectrum disorder. He had an extroverted personality, frequently hosting parties at his house.

+ Fully eiditic (photographic) memory, one of the only verified cases. He could read something once and remember it exactly decades later.

+ Universal supreme polymath. He completely mastered every subject that managed to interest him with little effort, and then subsequently contributed revolutionary breakthroughs at an alarming rate until he grew bored of it. He created the entire field of Game Theory, now a Nobel Prize field.

+ He was capable of profoundly complex mental computation at a frightening speed. He would often do the calculations in his head in seconds to minutes, and then confirm them on a computer (which he also designed), which did them over night. He would have his colleagues give him their data so he could calculate it and then compare the values to what they got from a computer, and was almost always exactly correct.

+ He had an estimated IQ of over 220. Nobel laureates and the scientific giants of the day were all in agreement that there wasn't a person alive who could match him in raw intellect.

Here's an abridged list of his achievements off the top of my head, and a link if you're interested in reading more:
+ He was instrumental in the Manhattan project and the creation of the atomic bomb.

+ He created many of the first true computers and his von Neumann architecture is essentially still used in all electronic devices to this day.

+ He almost single handedly saved the United States and the rest of the world from early Soviet domination.

+ He is the father of cellular automata, and is considered to be one of the greatest mathematicians of all time.

Unfortunately he died an early death, with a large chunk of his academic time being diverted to war efforts over science.

Schroedinger's cat has nothing to do with quantum mechanics; it's literally a classical probability experiment. Quantum features only apply when you have multiple possible experiments to perform, and their values aren't all compatible with each other.

Time is not a dimension.

Anyone who says it is can immediately be disregarded.

Time is also gay but not all dimensions are gay

Sloths move so slowly that moss grows on them. The moss helps camouflage them from predators.

The leaf of a fern is called a frond.

I read some papers about a possible link between obese, diabetic mothers and having a higher risk of autistic children. Would make sense since both obesity and autism diagnoses have risen in the past 30 years.

Could this be the remnants of an alternate reality?

Triboluminescence is a phenomenon in which light is generated through the breaking of chemical bonds in a material when it is pulled apart, ripped, scratched, crushed, or rubbed, for instance when squeezing a lump of sugar in the dark.

This process is STILL not fully understood.

Mosquitoes tend to like feeding on people that just ate bananas.

We have, in recent history, genetically engineered a species-specific virus to kill members of that species. What species? Rabbits.

This has been discredited: en.wikipedia.org/wiki/Hundredth_monkey_effect

>If suffer is the right word here.
Not it's not.

Prokaryotes are not monophyletic. In terms of descent it's not a meaningful grouping of organisms - there are prokaryotes more closely related to eukaryotes than to other prokaryotes.

Not moss, but cyanobacteria.

Pretty sure there's strong evidence for telepathy. This has been independently researched and corroborated more than once. For some reason, twins/relatives have an easier time reading each others thoughts than complete strangers. Read "Entangled Minds", I'm shit at paraphrasing.

Everything on earth has a 50°/• probability, it either happens or it doesn't

whoa

The great pyramid of Giza predates the extinction of the wooly mammoths.

Space is hot.

Although there are very few particles zipping about in space so if you go there you will feel cold the average velocity (IE temperature) is crazy high. Like surface of the sun high.

It's more sensible to say it has a high temperature but very little thermal energy.

The potato, tomato, and tobacco plants are all closely related enough to be crossbred.

Maybe it is

#NotAllDimensions

Why can't I get me some totatos then?
What about pomatos?

Would have to control for age, which increases autism risk in children and lowers metabolism in the parent (so higher risk of diabetes)

You could but they would suck and/or be poisonous (like potato fruit are - incidentally they look similar to cherry tomatoes). The cultivars are specialised in producing a specific thing.

I'd ask you for some sources but I know they're all shit.

This I'm gonna use in the next FE thread.

Actually well known facts if you studied medecine/biology, but:
Living cells contain mitochondria, organelles which possess their own DNA. It means all life is "parasitic" in nature, since it's the combination of two different "species" (if parasitic and species could be applied to micro organisms)

The worst existing infecting agent is prion, which is not even something alive, just weird proteins. No cure, and always lead to death by brain disease

Probably tastes like shit

Klinefelter is XXY, XYY is the disorder you missed

the only thing he couldn't count was calories

It's been said that in ancient time tomato were considered poisonous and only peasants would dare to eat them. Now we know they're safe to eat, but they are still poisonous. They're a member of the same family as the deadly night shade. Any part of the tomato plant that is green should be considered poisonous, including unripened tomatoes.

The green parts of potatoes (leaves and sometimes parts of the root) are also poisonous, which is why you should cut them out before eating them.

have we ever tried sequencing or modifying mitochondrial DNA? Could you use CRISPR to turn mitochondrians into midi-chlorians and give everyone Jedi powers?

It wouldn't be parasitic since even before evolutionary adaption, it was always a symbiotic relationship. The prokaryote provided a source of energy in exchange for steady nutrition and protection.

But it is one of truly humbling facts of biology, that for all our accomplishments, no man is an island onto himself.

>have we ever tried sequencing or modifying mitochondrial DNA?

No, we have sequenced hundreds of thousands of human genomes, and tens of thousands of other species, many of them bacterial. But no one have thought about sequencing mitochondria. Quick, a Nature or Science story is waiting for yor dear user

Most of the time when you do genome sequencing you don't actually separate the nuclear and mitochondrial DNA. It's not worth the effort.

So most genome (re)sequencing is also (re)sequencing of the mitochondrial DNA.

>Gravitational sling caused by ur mom

This is known as the Obertha effect.

Men's anal opening is shaped like a straight line/crack.
Women's anal opening is shaped like a star.

Thank you anatomy class for clearing this mystery.

>Why can't I get me some totatos then?
>What about pomatos?

Tomacco, Totato, Pobacco, Pomoto...

Let's call the whole thing off.

I was talking about the flyby effect, not gravity assists

You cannot transform direct current.

You must turn it into an oscillating current to transform the amperage and voltage.

If you pop a bubble underwater with soundwaves it briefly produces a flash of light and extreme temperature

ausfag here, tis true

to test the triboluminescence in a less messy get clear sticky-tape and quickly pull the tape off
it produces 10x more x-rays than lightning

>if suffer is the right word here.

Yes, it indeed is. God done made no junk

You're a perfect example of a person seeing patterns that aren't there. Give it some more time and you'll begin to see Satan in cars license plate numbers. or some other shit. Also Mandlebrot has nothing to do with Fibonacci.

This resemblance could even possibly be a proof we live in a simulation? Or possibly someone's imagination?

Isn't that, kinda dangerous?

maybe the earth stink. Feels bad man

>Someone's job was to research this.

I only half remember this but I remembering it being really cool. It's some sort of particle that crashes into the Earth at light speed. According to the laws of physics these particles should be deflected/adsorbed (don't remember which) before entering the Earth's atmosphere but because they're traveling at near light speed time moves more slowly for them. Because they experience time slower they don't get adsorbed/reflected the way they should and are able to enter the atmosphere.
What's the name of this? Can anyone help me out here?

neutrinos don't interact but it doesn't really have to do with how fast they're going

You are thinking of muons, they dont exist long enough to reach the ground from the atmosphere travelling just a bit slower than c but you can still detect them on the ground

if you die, you will not be alive... EVER. AGAIN

Watching people jizz over this image makes me cringe just as hard as watching christians jizz over laminin. It is the same fallacy.
There would be little resemblance if this was a different astrocyte and the pictures were coloured differently.

There are more atoms in a star than there are particles in the universe

There isnt even that strong a resemblance anyway
