I REMEMBER WHEN I WAS 7 OR 8 AND MY PARENTS TOLD ME I WOULD GROW OUT OF POKEMON
IF YOU HAD ROOM WITH ABSOLUTELY NOTHING IN IT AND THE WALLS CEILING AND FLOOR WERE MADE OF MIRROR WHAT WOULD IT LOOK LIKE IN THE MIRRORS
Holy shit I asked my dad who’s a physics teacher and he just looked at me, looked at the table, looked at me, tried not to smile, looked angry, and started to look up where you can buy big mirrors.
this is an actual room of mirrors.
as you can see, it leads to glitches in the matrix
Pshh. This is some entry-level nerd shit. Stand back.
It would be dark, obviously. If there’s nothing in the room, I assume there’s also no light source in the room. Mirrors reflect light. No light, and it’s just a room with glass walls.
"Fine, smarty-pants, then there’s a light source."
Okay, then the mirrors would infinitely reflect the lamp, or whatever.
"Ugh, then there’s just a magic floating ball of light in the middle of the room. No lamp."
That’s just a lamp with no sharp edges, if you think about it.
"UGH. Just imagine that the room is UNIFORMLY LIT, but not FROM anything. Or a laser beam just, like, HAPPENED."
Okay, well if we’re suspending the laws of physics now in this hypothetical scenario, we have to clarify a few points:
- Do the mirrors join each other perfectly at the corners, floor, and ceiling; i.e., with no cracks?
In the real world this would be next to impossible; the gap between each mirror would need to be significantly smaller than one wavelength of light. If not, what you’d predominantly see reflected would be those cracks. That’s one of the things that’s happening in the picture above. For this reason, this hypothetical is usually posed as a perfectly-smooth mirrored sphere, to avoid needing to talk about cracks and corners.
- Are these perfect mirrors?
That is, do they reflect 100% of all light on all wavelengths? Because perfect mirrors kind of don’t really exist. Did you know that your bathroom mirror only reflects about 25% of the light energy that strikes it back at you? The mirrors used in laser laboratories can get up to 80 or 90%, and I read about a mirror developed at MIT recently which apparently reflects more than 98% of light energy. The light energy which doesn’t bounce off the mirror is absorbed by it instead: at which point it becomes heat. Even if you had a mirror so good that only 0.0000001% of its light energy was converted into heat energy on every bounce, your light would still dissipate almost instantly, because of how fast light travels (and, therefore, how many bounces it makes per second).
- Is there air in the room?
Yeah—you know how I said that light energy becomes heat energy when it bounces off of an imperfect mirror (or, if you prefer, ‘literally anything’)? Well, passing through all those atoms and molecules it encounters in the air takes the same kind of toll. If you don’t want your light to be reduced to heat-mush before you can finish blinking your eyes, you’d need your room to be a perfect vacuum. And perfect vacuums? Yeah, those don’t exist either.
“UGHHHHHH. YES, okay, the room is PERFECTLY spherical, it’s coated in a PERFECT mirror, and it contains a PERFECT vacuum. Just tell me what it looks like, oh my God!”
Well…it doesn’t look like anything.
I mean…’looking’ implies the existence of an observer, right? You have constructed a hypothetical chamber which could not admit an observer of any kind. As soon as you cut a hole in the room to take a peak inside, all of the light would escape/be converted into a heat, and you’d be left with total darkness again. Even if you could construct a room like the one you’re describing, there’d be no way to know what was happening inside it!
“I WILL EAT YOU.”
—BUT: hypothetically, it wouldn’t be dark in there before you messed it up.
It would be white.
A perfectly featureless, perfectly regular, perfectly boring white room.
What did you expect? Light, visible light anyway, is white. You see colors when photons are absorbed by the atoms of a substrate, but we’ve already determined that these are perfect mirrors, so no photons are being absorbed. In your perfect mirror room, there is nothing to see: just light, bouncing around into infinity, doing nothing whatsoever of any interest.
•start at one corner
•find something from 5 years ago and stare at it nostalgically for 10 hours
•go to bed
if you dont have me on facebook you are probably not missing out on any posts but the comment section is important too lmao
I went to the Renaissance faire dressed as a warrior. I had a real sword with me, too. I was standing (in character) next to a sword-fighting ring, where kids of all ages got the chance to pick up a sword and challenge the champion. Some woman walks by, with her little girl. The girl starts walking towards the ring, saying she wants to fight. But the mom pulled her away hella sharply, and was like, “That’s for boys.” You don’t want to be a BOY, do you?” And the girl looked around and saw me. I think she thought I was a boy; I had my hair in a ponytail, and was wearing a hood. So she comes up to me and asks me, “Do you think girls can be fighters, too?” And her mom looks like she’s silently gloating. Like she thinks I’m going to say no. So I take off my hood, untie my hair so that it flows freely, and kneel before her. And I’m like, “Milady, anyone can be a fighter.” I swear, the look on that mother’s face made my day.
BAREFOOT IN THE BATHROOM I REPEAT BAREFOOT IN THE BATHROOM HE IS BAREFOOT IN THIS BATHROOM THIS IS A CVS NOT A BEACH NOT YOUR HOUSE PEOPLE HAVE PISSED ON THIS FLOOR AND JESUS HAS DIED FOR YOUR SINS AND NOT SO YOU CAN BE BAREFOOT IN THIS BATHROOM
Kristen is tired of shitty girl power movies
I apologize to Kirsten Stewart for all the times I made fun of her acting in twilight
have you ever gotten to a point in a text conversation where suddENLY EVERYTHING IS CAPSLOCK AND YOU’RE BOTH JUST SCREAMING AT EACH OTHER FOR NO REASON
my little cousin got bit by a house spider and she was crying so i went to get some stuff to soothe and numb it but before i could even walk out the door i heard her quietly whisper ‘i can’t handle the responsibility of being spiderman’
Racism and ignorance clearly evident in our society, as experienced by my friend’s sister. This is what her potential dorm roommate, whom she had never met or talked to before, tweeted about her.
"Today I googled my last name and found this as one of the search results. Apparently, just by looking at my profile picture, I am Indian and I can barely speak english. This, my friends, is a prime example of racial profiling. I am an American citizen. I was born in Houston, Texas. My roots are not from India but from Africa. My parents are Algerian. I am Algerian American. English is my primary language and it is a struggle for me to speak my parent’s native tongue. My name is pronounced exactly as it is spelled. I wear a hijab (a head covering), and not a niqab ( a facial covering that excludes the eyes) though I do admire, respect, and find the beauty in all those who do choose to wear the niqab. But this girl is right, I probably would have had a heart attack living with a person who could not, and refused to, respect me and my beliefs. I can only thank God for an opening of a single room shortly after they assigned this roommate, way before I knew she had posted any of this. Alhamdullilah. I also thank God for being born in Houston, one of the most multicultural cities in the United States, and not experiencing racism like this everyday of my life.
Sunday is my move in day and the start of my college career. This can be nothing but a good sign for the years to come, inshaAllah.
In conclusion, I urge everyone, please, don’t judge a person by their appearances. Racism exists in this nation because we continue to do so. We have to look beyond the covers of appearances and read the texts of their characters. Stand with me and #stopracism.”
She should be banned from life
this is so fucked up
how the hell did she get into college with a pea sized brain
the first person to poop must have been like ???????????????
As an infant they probably didn’t register what was happening
i was imagining a grown ass man. a man with a beard. a man hunting alaskan mammoths to provide for his family. i forgot babies. i forgot babies existed
