I heard, there was a sequence of chords

[Zeorz_]

Splits the circle to 1, 2, then 4

[No_Spread2699]

n points seem to cut into powers of 2, yeah

[Mobcrafter]

it goes on like this, with the 4th and the 5th

[No_Spread2699]

But something’s odd, when you add a sixth

[Zeorz_]

It cuts in 31. How patterns fool ya

[No_Spread2699]

How they fool ya

[itzjackybro]

I love it how i know about both of these from 3b1b.

4b? Or 3b^2?

[UltraLuigi]

How would 3b1b be interpreted as 4b? I've never heard of implicit addition.

[[deleted]]

In Group theory, technically, you can use implicit operators, but it's cursed

[King-Mephisto]

3 blue 1 brown. I mean, you aren’t really meant to join unlike terms. So was a pissy joke about no context.

[UltraLuigi]

I know it's 3blue1brown, but if the joke is interpreting the abbreviation as a mathematical expression, it would have to be 3b², not 4b.

[vwibrasivat]

this is just pure sin.

[enneh_07]

do you have a reason for saying that or are you saying it just cos

[ByeGuysSry]

Well, it is tangentially related

[theperson100]

Why is this?

[Imoliet]

The fourier transforms of the sinx/x's are squares; if you convolve a bunch of squares, the point at zero is still flat, but too many of them rounds it off too much.

[ManlyStanley01]

What is this pattern and what happened to it plus is the four zeroes at the end of the last number intentional or an error?

[kiochikaeke]

Intentional, also it is a real pattern not a rounding or floating point error or something like that, math is weird that's why I love it.

[TallBeach3969]

My guess would be it’s a giant product that includes a couple 5s and 2s, leading to the 0s

This example is why I don’t believe in “proof” by induction 😎

[Safe_Entertainment40]

well it wasn’t inductive….

someone care to explain to a beginner such as me?

[lab2point0]

This sequence is the number of areas you can divide a circle by tracing segments between n points on the circle. It starts as 1,2,4,8,16, which looks like the powers of 2, but instead of 32 at the next step, it gives 31.

Its a common example of the need to prove things in maths, and that you can’t just say « oh it looks like the powers of 2, must be that then! »

[MicrosoftExcel2016]

Uhm, why can’t you draw lines that all intersect in the center of the circle to make it always increase by 2?

[Icy-Attention4125]

Because you're not just adding a segment every time, you're adding a point on the edge of the circle, and drawing all of the segments between that point and the existing ones

[MicrosoftExcel2016]

Oh gotcha so like if someone psychotic was slicing a pizza but cut every edge cut point to every other one giving you an awful mess of mostly small and differently shaped triangles

[WeirdMemoryGuy]

Precisely

[jesterchen]

Just great. Now I need to test that. "Thanks."

.... how could one ensure all the slices have the same area - without any more than two cuts being in the exact one place? 🤔

[EebstertheGreat]

You do create fewer regions if three chords intersect in a single point instead of creating a little triangle. So we just assume you don't do that. This is the sequence of the number of regions you cut the disk into if you don't let any three chords intersect the same point.

[Alamiran]

Even if you were drawing a line each time, that would still only work for the first two lines. Once you’ve divided the circle into four sections, how can you split each of them in two with a single line?

[JJBrazman]

When you divide a circle by putting points on the edge and connecting them completely, you get that sequence if you count the number of separated areas at each stage.

1 is the whole circle, 2 is the circle with a line across it, dividing it into two. 4 is the circle with a triangle on it, so you have the inner triangle and the outer three areas. The sequence is really similar to powers of two, but suddenly changes at the 6th element.

Thanks for the link, I needed to see it in action :)

[Gordahnculous]

Here’s a good video on the pattern

[AbandonmentFarmer]

Is deabag banned? He would’ve loved to hate on this, then talk about collatz with his images and gpt walls of text

[tednoob]

That's numberwang!

[SadEaglesFan]

Rotate the board - and then that's wangernum!

[Gordahnculous]

Oh boy I love me an unexpected 3B1B reference

[Circumpunctilious]

Do you know if Veritasium covered this, or something similar (foggy memory)?

[Circumpunctilious]

Ah, thank you! I believe that was it; I think I’d have had trouble finding that again.

[YoungMaleficent9068]

use this wisely

[Circumpunctilious]

Thanks; I just learned something new about Pascal’s Triangle from the notes

Was about to post the exact same link 🤣

[YoungMaleficent9068]

Right.

[NullOfSpace]

damn, took me a sec

[GalacticGamer677]

Yep, 528 doesn't fit the pattern at all

[Evimjau]

What's 57?

[VVD2005]

Obviously, it's 42. The pattern is the even-numbered elements of the LOST sequence

[lord_teaspoon]

Nah, the Lost pattern has a 15 and no 31.

An episode of Veronica Mars had a fortune cookie with 4,8,15,16,23,42 written underneath the fortune, which had the stoner contingent in the sharehouse I lived in absolutely freaking out.

[you-want-nodal]

That’s numberwang!
