# When will ATHEISTS LEARN?????

Jonathan Lopez

Daniel Lewis

when won't atheists learn?

FTFY

Joshua Reyes

How does this guy calculate area of circle?

Robert Baker

it is not defined

Nolan Mitchell

Jesus christ that's retarded.

Colton Sullivan

I hate theists

Cooper Thomas

post the video i like to watch this kind of shit

Adam Howard

Turn 360 and walk right out

Connor Rogers

1 * 1/2 * radius squared

Bentley Sullivan

Gavin Evans

So according to Wildberger the area of a unit circle is 1/2? Really? Pure math=trash

Dylan Perez

You don't need radians to calculate the area of a circle

Joseph Kelly

He just defined one rotation as being one rotation.

Ryder Kelly

How do you do it without using an irrational quantity?

Alexander Walker

by being irrational yourself

Henry Ramirez

Isaac Richardson

You mean turn 1?

Eli Martinez

Tau will never catch on because it started as a retarded idea which everyone threw away, and redefining it is fruitless cause everyone already threw it away. Fucking it up even worse considering people are now throwing away a decently sensible number because it's associated with garbage.

Great lose-lose situation. Good job.

Liam Gomez

This is not [math]\tau=2\pi\ \text{rad}[/math]. This is [math]\tau = 1\ \text{circ}[/math]. [math]\tau[/math] is for turn angle. A rational, logically sound angle measure. No """theory""" of """real""" """numbers""" needed.

Bentley Perez

Half pi didn't stick

2pi didn't stick

1 rotation wont stick

Anthony Rivera

Eh, rotations will stick, I mean we actually do use them now already.

There's just no real difference between using degrees and a decimal, they're just different notations of the same thing.

One degree is just 1/360th of the circle, so if you use rotations instead then one degree is equivalent to 0.0027777... of one rotation.

Now, obviously degrees is much easier to work with as you are constantly using whole numbers, even if you go into using minutes as well, but it's still just another way of measuring the same thing.

Nolan Phillips

most computer languages uses radians by deafult. a rotation is 2pi rad.

Lucas Ward

>writing tau out that far

>not just 6.283..

Actual autism.

Jordan Jackson

no shit you dumb fuck

only turbo autists give a shit about notation. actually productive and intelligent people dont waste their time on something so pointless

Ian Thompson

This is not a notation issue. That's the tau=2pi autists. This is a serious issue about opposing the real numbers and bringing logic and soundness to mathematics.

Thomas Mitchell

What distance do I tracé over the circle when turning one turn angle?

Connor Lewis

>tau has only one limb while pi has two

>tau is 2pi not pi/2

MATH BTFO

Sebastian Morris

nice b8

Hudson Walker

Maybe there is no such distance.

Aiden Roberts

>brainlets don't know the circle is [math]\mathbb{R}/\mathbb{Z}[/math]

Jacob Turner

But how can a circle exist, aren't they counterintuitive? Circle with rational radius length will always have irrational circumference, and circle with rational circumference will have irrational radius

Logan Gutierrez

But [math]\mathbf{R}[/math] don't exist, so how can [math]\mathbf{R}/\mathbf{Z}[/math] exist? And according to Wildberger [math]\mathbf{Z}[/math] and even [math]\mathbf{N}[/math] don't exist because there are no infinite sets, so that makes circles even more non-existent

Justin Wilson

Circles exist but "circumference" does not have a length.

Luke Rivera

Did he even define a length of a curve? I know about his quadrances for line segments, but what about curves, did he try to define length (or quadrance, or something similar) for curves? And if he did, then how, constructing a length of a curve involves approximating it with infinitely many line segments, but he can't do that since he doesn't believe in infinite processes.

And about his turn angle thing, what does it even mean, how can he define that without a notion of a length of a curve? He can define full angle, or 2π angle in non-retarded units, but that's all. He doesn't have any measure of angles a priori, because he's just defining it, and without relating the length of an arc to the radius he can't define any angle other than 2π (and even that isn't defined well)

Liam Green

>tfw wildburger taught at my uni and might still be around

Cameron Thompson

do you not know about the rational parametrization of a circle nigga?

James Davis

I know about rational parametrization of a circle in [math]\|•\|_\infty[/math] norm, but that's not what he's talking about

Christopher Gomez

he's still teaching at unsw and posting videos of his lectures

Landon Carter

Rat/Int

Aaron Lopez

Which isn't homeomorphic to a circle.

And as said by Wildberger himself, there are no sets Rat, Int or Nat, because you can't take infinite bunch of numbers (assuming there are infinitely many) and close them in a finite object and label the infinity as something finite, which we have control over.

And assuming his other claim that there are only [math]10^{200}[/math] naturals (and therefore at most [math](2*10^{200}-1)*(10^{100}-1)[/math] rationals) then Rat/Int is fuck all and big shit and not is not even close to being a circle

William Allen

>[math]e^{1i}-1=0[/math]

Parker Fisher

This has something to do with pi being irrational i assume? Explain for a brainlet

Noah Brooks

The points of intersection are [math]( \pm \frac{1}{\sqrt{2}}, \pm \frac{1}{\sqrt{2}}) [/math], which don't exist in wildberger's mathematics I think.

Brayden Hughes

>But how can a circle exist, aren't they counterintuitive?

they go against weak intuition, but people like that should not be forced to learn maths anyway, it's animal cruelty.

Charles Jackson

his mathhistory series is fucking good

Luis White

if we're going to measure pi from the area of a circle, shouldn't we use sqrt(pi) instead? that way the area of an equivalent square to the unit circle is (pi*r)^2

Jaxon Sullivan

1 rotation does stick. We say revolutions per minute not radians per minute. OP is retarded as balls.

Luke Ramirez

*sqrt(pi)/2
