Pi Is (still) Wrong.

The Tau Manifesto

I am a recreational mathemusician currently living on Long Island, NY.

I like most creative activities that involve making a lot of noise, mess, or both. Aside from composing, I love improvising on various instruments, drawing, sculpting, and other methods of making things. My main hobby is mathematics, with special interests in symmetry, polyhedra, and surreal complexity. This usually manifests as collaborative research in computational geometry and other areas of theoretical computer science, or as mathematical art. I think the human brain is incredible and strange, so I have developed a great interest in dreaming and consciousness. As a result, I am a trained hypnotist and a lucid dreamer. The human body is pretty neat as well, so I enjoy dancing and judo. I always love to learn new things—variety is the food of creativity!

There are a lot of discrete mathematical (series) implications to pi as well. I believe that's what standardized the use of pi being pi and not being 2*pi.

In fact, geometrically, beyond trig, if you look at areas and circumferences your options would be looking at the alternative function of area=(pi/2)*r^2 instead of just (pi)*r^2. Now would it be easier to have 2 variables, tau and pi and remember when to switch between the 2? No. Really, learning basic trig would be the only advantage of this...which is a minute part of the math world.

The sad realization *for those who've only seen a few videos of hers...like me* is that her intellectual attractiveness is diminished by noticing her physical attractiveness (of approaching the model-esque figure and wearing the stripped "armings"). Hell, I would be happy to be in the "this adds to what she already has" camp but it's not right for me. Now I am thinking that she looks like a geek-CHICey attractive girl with a beautiful mind, rather than a pure intellectual buddha-like personality. It especially scares me when I want to think of my ideal self speaking out towards the equality among sexes and commending her work without discrimination, but ending up saying the same shit like those I loath based on sexual viability. So to all those on VideoSift, why do you lead me to doubt myself?

Seriously, read the manifesto. Area = (tau/2) r^2 actually makes more sense, too.

Dude that manifesto is fucking hilarious...all of this math knowledge spouted and all for what? All because he doesn't like doing fractions??? Really??? Yea let's rewrite all the math texts since before Princia Mathematica just so you can use tau/6 instead of pi/12. That's useless knowledge wasted on somebody with no common sense. Furthermore, it adds unnecessary fractions in things like Euler's identity and like what you just pointed out, the area of a circle.

Yogisays...

Found her video on the sift awhile ago...been hooked ever since. I don't even like math but the way she thinks and presents ideas is just the greatest thing ever...I'm in love with her brain.

Check out her blog that Sagemind Posted.

Well, it's certainly unrealistic to expect that we can get rid of pi in favour of tau after over two millenia of pi's monopoly. But one can dream, can't one?

What I'm saying is that there's no reason to get rid of it...why's it worth trading 2*pi here for tau/2 over there?

Ornthoronsays...

@rottenseed: Well, as a physicist, I definitely encounter the factor 2*pi much more often than pi. I conjecture that this is true in mathematics as a whole as well, since 2*pi = tau is one full turn of a circle, and one full period of a (co)sine wave. Tau is as such a more convenient choice, if you have the luxury to choose.

Psychologicsays...

Pi vs Tau reminds me of Qwerty vs Dvorak... the small gain in simplicity (or typing speed) is more than offset by the burden of the change, and learning to use both would be more confusing than using the current standard.

I'd be fine with the change, but I think π is cuter. =)

dannym3141says...

I agree, this one was crap.

Though i am interested to know how she managed to get a pop culture reference into a video made in the 1970s (cos these vids always remind me of an episode of pete and pete)

carrotsays...

Also, personally, I prefer Dvorak. Especially the Symphony from the New World.

glad i dont have to go to youtube to hear people spout off about whats not good enough for them


Glad i don't have to go to youtube to see people replying to people spouting off. I didn't realise we were short on comment space, nor that you were forced at gun point to read every comment.

But i do appreciate you ignoring other people saying this one wasn't up to much but singling me out for agreeing with an ongoing drift of opinion. Much obliged.

Meet me at my lair, we will discuss in detail on how this girl and whomever wrote that shite manifesto are shortsighted and why...

Will include orgasmic information that will melt these mortal's minds. We'll make it private so no buddy stumbles in by accident a turns to stone.

mentalitysays...

I propose that we use a new symbol in place of tau. It shall be named "Two-pi", and coincidentally, it looks like the digit 2, followed closely by the greek letter pi.

There. Problem solved, and everyone is happy.
