Get on my level.

oh that's a 3d one, cross your eyes and look at the one in the middle
pretty cool actually, wish I had more
ok last one

It's all made up nonsense, using analogy to try and visualize something that is not real.

Makes for cool gifs, though.

Or why not go completely mad!?!

Oops, sorry, why did I post the exact same thing?

I want to buy a laser but i'm not too sure on everything.
I live in UK so i dont know how powerful a laser can be, or which colour is the 'best'

I need some help, I am applying to university and a job at the same time(same place) and I need to write a personal statement and i'm not too sure what to write in it.
So can you guys paste yours? or help?

>tl;dr
>every phenomenon that can be written in an equation has an analytical expression it follows. Or if it doesn't why.

Say you have a nonlinear partial differential equation of any order with sufficient initial or boundary conditions (all physical phenomena). Then that equation has a unique solution. For a distinct set of parameters and initial/boundary condition there is a distinct numerical solution to that differential equation. Which means that for a different set of parameters there is another ( maybe different maybe not) solution. Which means that there has to exist a function that translates the set of initial conditions and the set of parameters to the right set of solutions over a distinct area (area being set of parameters and condition for which the original differential equation has a solution). There has to exist an analytical expression that replicates that function to fit as well as....completely. That analytical expresion is the solution to the partial differential equation. The equation therefore has a solution which is analytical.
Similar reasoning can be applied to every single expression which means that everything has to have an analytical soltuion. Why do they teach us some thins are not analytically solvable?

bump.

i need halp here

Welcome to the TeX Quiz! A series of questions will follow. Your job is to turn the question into proper TeX format. This is to see how well /sci/ can handle professional scientific/mathematical typesetting. Place all answers between "eqn" tags, not "math" tags. As soon as someone gets the question right, the next question will be presented.

1. The limit as alpha approaches negative infinity of 2 alpha divided by p, all (so including the limit) divided by r.

188 first go. Don't overthink, if it looks right within the first 2 seconds click match.

Hey, so back in the day my graphing calculator (which was awesome and i'm so pissed i lost it) had a program that could take 3 sets of x an y values and turn it into a quadratic equation (sometimes not quite right, in that it had to average, but it always made the best fit), I've tried googling such a thing and it seems fruitless, anyone know where such a program can be found?

In case anyone is wondering, the three values in question I want a formula for are (1,1);(2,5);(3,23), this is just for my own curiousity, however it does come from a real world problem.

Hello /sci/.
I think I have a poorly defined solution to this problem...
Imagine a 1D line, divide it by 1 point. What is the maximum amount of lengths that you can get? What about this 2 points? 3 points? etc.
Imagine a 2D plane, divide it by 1 line. What is the maximum amount of regions that you can get? What about with 2 lines? 3 lines? etc.
Imagine a 3D space, divide it by 1 plane. What is the maximum amount of rooms that you can get? What about with 2 planes? 3 planes? etc.
Imagine a 4D hyperspace, divide it by 1 space. What is the maximum amount of hyper-rooms you can get? what about with 2 spaces? 3 spaces? etc.

Imagine a dD hyperspace, divide it by n (d-1)D hyperspaces. What is the maximum amount of hyperrooms you can get?

Picture related, it is how many fucks are in my head right now

300m get!

/sci/, if you could witness any event in history, which would it be?

Being the Nikola Tesla of the 21st century would be nice, but I'd be content with a double major in physics and mechanical engineering.
