Surface area of cylindrical human
How to spot a mathematician/physicist.
You've been instantly teleported two feet to the left. How does this affect you?

I'm actually a chemist, thankyouverymuch

I feel like a mathematician would go a step further and not even assume a specific geometry. Maybe a human is just a subset of points in a measure space, with a measure fixed at 1 human-unit.
To be fair, the result of this calculation only depends on the area/volume ratio of the human. I used the specific cylinder, because humans are roughly cylindrical, and have a volume of roughly 100 L. The surface area of a regular human is probably a bit larger than that of a cylindrical one though.
Thank you for taking the time to do the actual calculations, you are a legend!
Oh, you're assuming a monolayer. Yeah, you're right then. I thought you were talking about the vacuum end and the air was magic-ed out in a more orderly fashion at the other end.
This guy sciences.
I mean, no. That's not enough energy to cause nuclear stuff. This guy tried sciencing, which I still respect in the context of a goofy scenario, I guess.
The math actually says that we might quite possibly get nuclear stuff. I checked because at first I intuitively thought the same thing as you.
Wouldn't that mean opening an evacuated tube should produce a flash of radiation, and supersonic planes should absolutely glow? I'm skeptical.
That might do it, if they really land on top of each other. OP said it was air molecules colliding with each other in the shock, though.
Depends on what teleportation technology we're using. I think a lot of us assume that when you're teleported you're quickly assembled atom by atom and don't simply instantly exist in a new location.
I assume it's a switcharoo scenario. Otherwise where does the air in my new location go?
I'm wet and sitting on the tile floor. I'm cold :(
Why would air displace so quickly?
Instantly moving any kind of mass in the context of physics means moving it super close to the speed of light (well actually, it would have to be faster than the speed of light for truely instant which opens up a can of worms all its own so lets just say really really close to instant, as close as the universe lets you get without inviting FTL time paradoxes) which would impart insane amounts of momentum energy that has to transfer to the air it pushes.
That supercharged almost-speed-of-light air needs to go somewhere (unless were talking about the kind of teleportation where atoms get transposed into each other in which you just skip to the nuke step).
It would still have to repel the air with electromagnetic forces between electrons, so the total speed is still limited. Or does the air just stay in place inside your body? If not, then the teleporter would have to move the air somewhere.
I'm pooping next to my toilet, inside this wall. The tp roll is in my belly.
I have simultaneously merged with my desk. My bowels have been displaced and are now bisected with bamboo. I feel simultaneously ripped apart and yet stuck and solid. Every point of my being is as though it has been engulfed in flames. My existence and identity has now become insufferable pain. I feel an impending sense of doom at a foreign body now lodged inside of me.
There are no wounds for me to bleed from and I cannot gasp for air to scream. My spinal cord has been severed and I feel hot prickles on my cheeks and my ears feel as though they are being stuffed with cotton. An internal white hot pressure feeling erupts up my now-fractured spine until it reaches the back of my head and radiates towards my forehead. My peripheral vision looks like static and everything appears to shake. I am unable to make sense of anything and everything goes dark and still.
U killed me op wow
They could have become a prolific horror writer but instead they've been desk-integrated.

Is it occupied?
I'm now shitting in my bathtub....
I am now shitting in the sink.
Weird. I also move into a space occupied by my desk, but a Fey mood takes hold of me and I grab the left corner of the table with my left nostril and wrestle it into an oak masterpiece which I then sell to an Elf, just to piss him off.
Are you a commoner? You'd better hope to roll REAL low on that damage or this isn't gonna be pretty
I'm shitting in the shower.
I'm squatting on the landing at the top of the stairs and now need to shuffle off in shame to get some TP for my bunghole.
Not with that attitude
Maybe we should stop forcefully removing cats from the locations people gather the most. Grocery stores. Churches. Places of business. Maybe the Egyptians knew a thing or two about keeping the Gods happy.
Edit for the downvoter: maybe you didn't get the joke, but Egyptians basically worshipped cats. https://en.m.wikipedia.org/...
I'm reading this while laying on my right side in my bed. So I suppose I bounce on the bed then. Seems fun!
I hover briefly in the air, next to my bed, and hold up a sign that says "uh oh" before I fall a couple feet to the ground onto carpet. I might hit my head on the nightstand, but I feel like I got off easy compared to most other people.
Me too! Hi floor poop buddy.
Taking a crap in the hallway
hovers in air next to sofa, looks down, looks at camera, holds up sign saying "uh oh" and plummets two feet to the floor creating a puff of dust on impact
Woah, lemmy is for shiters.
i just fell off the bed ouch
Same, but I'm stuck in the small gap between the bed and the wall
Not much, I'm just lying on the other side of the bed. Although my pillow has been replaced with a garbage bag.
Well now I'm sitting in a different chair. And I don't like that chair as much. 😡
Fusioning with the atoms of the wall next to me. So parts would stay me, others would just transform into very high density stone or something. The meat may fall off or needs to be cut off, luckily my head would be completely inside the wall.
sl you dropped this
I'll have fallen about 3ft, landing directly on my coccyx on a hard tile floor, causing additional damage to 2 discs in my lower back that I've already had worked on twice. There's almost a 100% chance that this will result in my needing to have those two discs removed completely.
So I really, really hope I don't get instantly teleported 2 feet to the left while I'm sitting here.
I'm european, so it doesn't affect me at all.
I might be stuck in the floor since I'm laying on a mattress on my left side.
Closet for me
If this involves some kind of adjustment of orientation, then I will be doing an early Father Christmas act and coming down from where I have appeared halfway up the chimney (being generous about how wide that chimney is). If it doesn't, then I am going to be part of the brickwork - except for my guts and arse, which will rot in place in the chimney over the next few weeks.
I'm still on the couch, slightly further away from my wife.
I am in the vacuum of space.
Meaning you're on a space station right now?
Inertia isn't preserved during teleportation. So you'll most likely end up either in space or the Earth's core.
Wouldn't that mostly depend on how long teleportation takes? But if it's instantaneous, you wouldn't need to account for inertia to end up literally a couple of feet away from where you are, right?
You underestimate how fast we're moving through space.
That doesn't make any sense. If I'm instantly transported 2 feet to my left I'm still going to be in the same room, not in outer space. Maybe you're thinking of this issue with time travel?
I'm now outside the train going 200km/h and have a nice, hard and long fall in half a second to look forward to.
I find myself sitting inside the end table next to the sofa, instantly destroying it along with a lamp a ukulele, and several glasses I haven't taken to the sink yet
I am now sitting on the laptop my company gave for work, most likely breaking it. Which is unfortunate, but I can probably just request another.
I live in the wall now.
My cat Ralph is not gonna be happy about that.
I'm pooping. Two feet to my left is a wall. I'd be inside the wall D:
Whose left? If I'm lying on my left side do I go straight down?
Not this again.
I have a bag of Skippy Peanut Butter Balls lodged in my ass. If I move they won't be there any more ( ͡° ͜ʖ ͡°)
I'd be shitting in the neighbor's toilet. It would probably be hard to explain why I'm in their apartment in my underwear.
You take shits with your underwear on?? You wild dog
I cut a big hole in the back so I can shit through it though. Can't stand the cold seat on my cheeks.
I am now sitting in a different chair at the same table. I continue browsing Lemmy on my phone.
I am now a propane stove/human hybrid.
Very uncomfortable. You've pulled me off my bed and now I'm laying naked on my power inverter.
I'd be on the floor. Which is a problem because I have a broken ankle/leg and can't put weight on it for another week.
Inside my coat closet...not the first time I'll struggle getting out of one
I fall to the floor and possibly hit my head on a table on the way down.
I am now out of my cozy and comfy bed and on the floor while hitting my head on my lamp :(
I'm in a sitting position, one foot beyond my desk, with my feet about 10 inches off the ground, and my butt is about 16 inches off the ground. I fall on my ass comedically, amidst loud cursing.
Stuck in concrete wall / window T_T
I'm laying on my side in bed, so.... I guess I jump two feet in the air, fall, make a big sound, probally bounce off and break some stuff and then have back problems all day.
I now have to crawl back onto my couch. And I'm cold now too.
I am now sitting on the left side of my bed instead of the right one.
I am impaled by the edge of the couch.
It depends on whether I displace the wall, or the wall displaces me.
I'm now shitting in the tub and about to fall right into it.
I'm now on my husband's lap as he driving us 70 mph on the highway.
That seems highly unsafe.
A chunk of file cabinet where my knee was falls to the floor. I fall to the ground, twisting my hip joint quite uncomfortably, possibly enough to pull something. I can't actually tell if my leg would be totally trapped, or if I could at least slide it out. If it's caught it's going to be a shitty wait for rescue.
I just fell off the couch.
I am now sitting on the roof of my house. Is a bit damp, but could be worse.
I I am now sitting on nothing in the walkway through my living room. I fall on my butt on the carpet, severely swear, and then try for a bit to figure out what the hell just happened.
Depends Is that like 4 school buses or more like half a pen?
two feet = three chinchillas.
Bigger than a feet. Am I big foot? Oh no!
Damnmit. I asked that kid to clean off this coffee table and now there's a pepper grinder, a bag of terrible candy, three remote controls, and some crushed fortune cookies, all under my back.
Shittin in the shower
I'm probably partially inside a dishwasher now and now we have to wait forever for the apartment managers to replace it and the counter.
AKA my life becomes slightly harder as now I have the first world problem of having to manually wash and dry dishes by hand.
In sitting under my telescope
I fall off the radiator attached to my wall.
I'm now sitting partially inside my couch's end table. My wife just fell down the stairs.
You just discovered the tensile strength of the color green is umpity dumpity 400. How does that make your left nut feel?
That's how utterly asinine these kinds of queries are.

The pocket of air that was where you teleported now get displaced at a very decent fraction of the speed of light while the pocket of space you once ocupied becomes a almost pure vaccum. the air moves so fast it creates a sonic boom that ruptures the ear drums. Then, a few atoms of air collide together with such incredible force the atoms split and causes a small grade nuclear explosion.
