I support this if we use this equation.

[math] \sum\limits_{n = 1}^\infty n = ? [/math]

Nope :^)
It should be a quiz about our favourite scientists.

Too easy. Replace it with a proof.

The question should be "Are the reals real?"

The answer is no.

>>7762425
we need another wildburger thread to be honest.

If possible, it would be cool to have the captcha pertaining to the thread topic

that's a dank idea

>>7762405
Not like you can stop people from just punching it into Wolfram before they shitpost

bots would be better at solving it than most people that post here

>>7763104
present the equation/question in a picture, like captcha does already.

I agree.
Fuck homework plebs :^)

Dude, you're posting on a site owner by a jap. This is weeb territory, get over it.

Anyway, the problem is a spambot could simply use Cramer's rule to solve the equation. It'd be tough to implement this in a way that's actually secure.

>>7763089
They'd still have to know how to properly input it.

Only if it doesn't include negative numbers I always get my signature wrong ; ^)

>>7763089
differential equations are easy to put in words and there's no way they could figure out how to write it in a way suitable for wolfram

>>7762649
24 already?

Dumb idea. If it's difficult, it's gonna be annoying as fuck after the 3rd time. If it's easy, it's gonna be cringeworthy and look like a highschool board

>>7762405
As a math postgrad I would not bother filling in that captcha just to post a single post in this shithole. Especially not after it's filled with pretentious twats who would actually bother to still post after that.

it's Science and Math. Not everyone who comes here has to be a math expert. Some of us are biologists and chemists which only has to deal with a very basic level of maths.

Oh, I have one! Let's make it so the OP of the thread can ban people from and delete posts from his own thread.

>>7763492
by your logic I should only post jewy stuff on facebook since its owner is zuckerberg

gtfo with your tripcode and shitname, lardass

I support this. Even putting a simple geometric proof will filter out all of the /pol/ and /b/tards.

>>7763492
Lol as if systems of linear equations even fucking get close to the minimum skill this board needs.
The new captcha would be for people, not for bots, fyi...

make the equation P = NP to see who knows their shit on /sci/

this actually happened BTW. anyone remember when they 1st added capcha to 4chan?

>>7762405
I love this but it would have to be a word problem because you could still spam by feeding an equation directly into a CAS.

>>7765697
Why do I want to read these. I'm not even that much of a weeb.
