Is it engineering tiem?

>>1577987
Not so much. I'm thinking more, those images you draw up when you're high and you think you've come up with something absolutely genius, but you've forgotten about some fundamental law. Diagrams and shit.

I did one of these about infity equaling 4 one time, i was freakin out

I think this is not exactly what you're looking for, but close.
If my 4chan folder wasn't such a fucking mess, I could find mroe of these.

>>1578025
That does not compute. What's the trick? I'm too blind to see it.

>>1578033 Spacetime is CONSTANT (always 100%)
I call bullshit

>>1578061
When you sqrt both sides you have to add a +/-

like this op?

>>1578069
Care to elaborate?

>>1578061

Some people would call his method of turning the equation into squares "bullshit"

or this

>>1578073
Spacetime isn't constant, that's where gravity comes from. In general, the metric is a function of spacetime coordinates. Take the Schwarzschild metric for example
<div class="math">g=
-\left(1-\frac{2M}{r}\right)\mathrm dt\otimes\mathrm dt
+ \left(1-\frac{2M}{r}\right)^{-1}\mathrm dr\otimes\mathrm dr
+ r^2\mathrm d\vartheta\otimes\mathrm d\vartheta
+ r^2\sin^2 \vartheta\mathrm d\varphi\otimes\mathrm d\varphi</div>
Not very constant, if you ask me, especially for r=0 :>

>>1578101
Pretty sure the infographic (made for /b/tards) was meant to splain special relativity, not general relativity.

>>1578098

>>1578113
I'm not sure whether adding an image of bent spacetime and saying "always 100%" were smart choices then.

>>1578098
why wouldnt this work?

>>1578076
>>1578086
lold hard

>>1578117
It is a dumbed down verision for /b/tards, goddamnit. Take shit like that with a grain of salt (or rather a mountain).

>>1578120
Infinitely rigid objects don't exist. Electromagnetic forces between the atoms of the rod propagate with lightspeed.

>>1578087

>>1578099
turn around faggot

>>1578120

takes time for it to propagate through the rod.

information is actually transmitted at the speed of sound

>>1578115
For some reason I find this picture as funny as hell.

>>1578115

>>1578101
Well... spacetime interval is an invariant...

>>1578201
... and how's that relevant here?

>>1578117
>>1578101
>>1578069

it's a FAKE infograpghic, it's not forreal

Just made this one.

>>1578209
It's a very benevolent interpretation of "spacetime is constant".

>>1578078
I don't understand why is this not ok?

No one in my class could understand this.

I was disappoint.

turchne the

>>1578342

no constants of integration. indefinite integrals need them to make sense.

>>1578356
Indeed, but takes lots of people very long to realize that. The indefinite integral symbol represents an equivalence class of functions, not *a* function, which is why <span class="math">1+ \int f(x) dx = \int f(x) dx[/spoiler] makes sense. Both sides represent the same set of functions.

I like it because it is a bit more subtle than the ones where you divide by zero or go from x^2 = y^2 to x = y.

>>1578078
Can anyone explain to me why this is bullshit?

>>1578371
Yeah it is a good one for stumping people.

<div class="math"> x = 1</div>
<div class="math"> \frac{\mathrm{d}}{\mathrm{d}x} x = \frac{\mathrm{d}}{\mathrm{d}x} 1 </div>
<div class="math"> 1 = 0 </div>

seems to bring out some pretty strange reasons from some people as well.

>>1578405
Hey, OP wanted these.c

>>1578007
I know it won't work, but can someone explain to me why?

>>1578421
magnet pushes car

but

car pushes magnet too

>>1578428
actually magnet PULLS the car, so there should be no problem

>>1578429
Oh really?

>>1578444
Newton was a fraud.

>>1578429
If you don't understand this then gtfo.

If you're trolling.. have fun, I doubt you'll leave since this is the easiest board to troll, my post might be even proving tha.

>>1578447
No he wasn't lol.

Maybe the guy wasn't 100% right in the head, but thanks to him we have calculus.

>>1578109
sqrt1 = sqrt1
sqrt1 = sqrt((-1)^2)
1=-1

>>1578099
This one doesn't belong here because it isn't really troll-ish... It's a decent question with a straightforward answer. The bullet would fall straight down, relative to an observer outside the train.

>>1578355
Is he humping the nose of the ship or what?

>>1578147
Also, a five-lightyear-long rod would collapse under gravity into a star or possibly a black hole.

>>1578485
Unless it's made of the hardest metal (diamond).

>>1578478

That would work,if portals would work. Either way, those guns are just a massive trolling to space time.

>>1578490
Everyone knows that Dragonforce is the hardest metal known to man

>>1578490
>diamond
>metal

this one's great

>>1578535
That light sun looks like a slice of lemon to me.

God damnit /sci/ stop making me hungry.
