the rules are these: you choose one of the following terms, and try explaining it as simply and as well as you can. most important thing is being able to explain it well enough for a complete layman to understand, but at the same time keeping it as accurate as you can. also, you can't use google or other comments to find inspiration. it has to be all you. after commenting, rate other people's definitions. the terms you can choose from: easy mode: >vector >electric charge >energy >gravity (classical definition) >information
hard mode: >time >entropy >gravity (GR definition) >field (the mathematical meaning) > dimension
let's see what you got. if you wanna define something off the list go for it, but keep it in the same "style" as the other terms.
Sebastian Reyes
I choose electric charge. Where to begin... See attached image
Luis Flores
Holy fuck that's Rich Evans.
Nathan Lee
2/10 not allowed to use pictures or other outside assistance + not understandable at all.
Aiden Mitchell
>time
Time doesn't exist.
Asher Flores
Time is a unit of measurement used to order sequences of events or figure out the distance that things happened between the beginning and the end of it.
Henry White
i have a feeling a thread like this would thrive in /x/
Hudson Adams
Time is what happens when nothing ese happens
Wyatt White
>field (the mathematical meaning) A field is a function of Rn to Rn. >vector A vector is a set of one or more numbers. These sets need to abide by certain addition and multiplication rules. (they have to be linear)
Xavier Ross
Wait what about scalar fields? I thought a field is just something that has some value everywhere on R^n. Don't scalar fields go R^n -> R ?
Jaxon Cruz
A layman could not understand this. 5/10
Lincoln Martin
Scalars are unidimensional vectors :)
Isaiah Gonzalez
>>gravity Its a force that points towards the center of the earth. The fatter you are the harder it pulls. It's the fatophobic force. It makes
Nicholas Cooper
>>field (the mathematical meaning) It is a mathematical object that assigns a value to every point in a space. Like temperature, where every place you put a thermometer has a given temperature.
Connor Miller
Sure but they don't live in R^n. A map from R^n to R^n maps a vector to another vector of the same dimension. A scalar field maps vectors to numbers. A tensor field maps vectors to tensors. Unless us physicists have been using the terminology wrong this whole time (wouldn't be surprising), fields are just things that have a defined value at every point in the space.
Also what you say isn't the most accurate thing in the world since you need some definition of a scalar as its own thing in order to define a vector space but whatever.
Matthew Harris
wrong terminology it is a function from Rn to Rm
Jacob Rogers
Fuck laymen. They don't need to understand that shit.
Joshua Stewart
Tensors don't live in R^m for any m. Also complex scalar fields don't map to R they map to C
Aaron Peterson
>dimension Maximum number of directions you can define to be mutually orthogonal.
Jonathan Murphy
That's a vector field, idiot.
Bentley Foster
lol temperature isn't a vector dumb dumb
Jayden Adams
alright its a function from field An to field Bm. He asked for vector fields not tensor fields also how would you define a tensor field?
Caleb Adams
Thank you for your wisdom oh wise one. I see that your e peen is bigger than everyone else's
Owen Jenkins
He asked for "fields (mathematical definition), so you are both wrong. A field is a special type of ring, and a ring is a special type of group. Look it up a-holes.
Oliver Barnes
the amount of disorder a system can contain.
Dominic Wood
Yeah Im explaining vector fields then. Your explanation on what a field is is crap. A layman would say a ring? like lord of the rings?
Cameron Powell
entropy*
Ryder Walker
What, entropy? No, that's not it.
Joshua Jenkins
then what is it?
Nathan Reyes
It's often a measure of disorder but it isn't defined that way. In statistical mechanics it's a log-scale measure of how many possible micro states make up the systems macro state. The macro state is just what we call the overall state of the system (you might describe this with things like temperature, volume, pressure...) while a micro state just refers to any small change you could make to parts of the system that don't meaningfully alter the macro state (swapping the positions of two atoms, changing the velocity of a few atoms...). Entropy basically ends up being a measure of how many different ways a system could exist in the way it does currently, which happens to also be a good measure of how probable the state is (and also, as is most commonly understood, a good measure of disorder). High entropy states are (by this definition) guaranteed to be more likely than low entropy states. This definition of entropy happens to correspond with a separate definition that has to do with heat transfer and is far less intuitive, but it is associated with the irreversibility of a thermodynamic process hence its significance.
Caleb Edwards
Meant to reply to this one
Cooper Howard
Laymen can suck my dick man I don't give a fuck
David Richardson
nice
Samuel Howard
Non-laymen don't need your snob ass to explain shit to them. So you're basically useless.
Easton Scott
Good thing I never actually gave an explanation for anything on this thread, only criticisms and complaints. If that's not useful to anyone then I don't know what is.
Tyler Davis
> If that's not useful to anyone then I don't know what is. That's right.
Nathaniel Myers

Luis Roberts
0/10 bad comment. adds nothing to thread.
Oliver Rivera
A field is a set of things that can be added and multiplied with the same rules you use for regular numbers.
Do I win?
Thomas Wood
>time big hand goes round clock fast, small hand goes round slow
you can't explain that
Christopher Gutierrez
The dimension of a space is the number of independent directions you can point in.
Vectors are objects that you can add together, squish, and stretch to get other vectors.
Dylan Allen
>The dimension of a space is the number of independent directions you can point in. >3D= infinite directions you're a faggot
>He still thinks of vectors as having a "direction" they "point" in
What is a polynomial
John Brooks
a sequence of infinite number with finite support
James Gomez
>implies shitpost would have been less of a shitpost if only user understood function spaces
Juan Myers
>pointing boi I lost
David Wilson
Move "moving boi" from energy to vector, and replace it with "hyped boi" or something. And replace field with "number boi", since 'mapping' is too general that it applies to just about everything.
Hudson Foster
so vectors are silly putty? and what about non spacial dimensions?
