[Submitters note: The following quotes are from the comment section on the linked blog post. More examples of crackpottery are quoted in the article itself. I've also done some serious snipping of quotes because they're pretty long, and any text in square brackets is added by me.]

Liddz: Traditional Pi = 3.141592653589793 is also false because infinite polygons cannot exist. A Polygon by definition is a plane figure that can fit into a circle with a limited amount of sides. Fractal geometry with the help of computer software has proven that it does not matter how many times we divide the circumference of a circle into different sections gaps will always exist upon the circumference when the curve of the circle is magnified and we zoom in to look as close as we can

Traditional Pi is good and okay if you are not worried about accuracy, but if you really want to get scientific then you will have to use the Kepler right triangle method for getting Pi and that method is simple and can be done in just 5 minutes or even less than 5 minutes and does not require a super computer with spread sheets

[...]

Traditional Pi is both irrational and transcendental so we cannot use traditional Pi to square the circle but Golden Pi 3.144605511029693 is irrational but Golden Pi 3.144605511029693 is not transcendental:

4th dimensional equation/polynomial for Golden Pi = 3.144605511029693 (x4 + 16×2 – 256 = 0).

Yo Soy: What is the mean interest in hiding the true value of Pi?

There are BIG interests that oppose to a corrected value of Pi.

1. Khazar academic mafia does not want the freedom for humanity.
2. A corrected Pi collides with the interests of the oil industry and the Khazarian control of petrodollar.

When PI be corrected humanity will discover an endless source of energy that will liberate humanity from slavery and the dependence to other energy sources.

The number Pi have be maliciously obfuscated to prevent the close of a cycle to some energetic resonance phenomenon which will take humanity to an ENERGETIC GOLDEN AGE and the conquest of deep space.

TRUE VALUE OF PI:

Pi = 3.14460551102969... [cut for length]

REMEMBER THIS PURSUED NUMBER ABOVE.

markcc: In recent years, every mathematical crackpot seems to make random claims like yours, about how their better math will solve all of the worlds problems and give us the key to free energy.

So please, explain how, if the value of p is off by less than 1%, correcting that will somehow produce free energy.

Further, explain to me how, exactly, every company in the world that produces round products hasn’t noticed that they’re using *more* material than their calculations say they should?

Answer those two, and maybe, just maybe, I’ll spend a couple more minutes looking at your rubbish.

Until then, stop wasting my time.

Kurt: It would bring humanity into a new computing era where we could algebraically determine the value of key trigonometric functions. Essentially if you have ever used MatLab you would know the program takes a while to compute things and needs a lot of computing power because it has to run intense calculus and trigonometric functions to arrive at values. By making Pi algebraic as Phi it would simplify all of math.

unknown: you are absolutely right on this , understanding of the circle would lead humanity to understanding of the universe — you are right that , this brainwash is work of the cabal — i just add and vatican to — but this ratio is wrong —. circle has a finite circumference , that’s why it is wrong — this guy who wrote this article is missing one thing to .. our decimal math has nothing to do with nature and geometry .. and for example he has not knowledge that the most important formulas like C=2pi*r and A=pi*r^ have not proofs in geometry , he is just another brainwashed zombie and doesn’t understand that calculus is based on Pi , not Pi on calculus —. our Pi is wrong,no doubt about that ..but Jain Pi is wrong to — i recommend to watch this ..

Barba truco (@barba_truco): Why does a helpless book (the book of jain pi) makes to tremble your archaic mathematics foundation in such a way!?

Even you wrote rivers of paragraph trying to circularize the book of jain-pi.

That means that this book is true.

Kaliman: I can see fear and rage on words against Jain— why ? there is no need— you may not agree— but in a friendly way— that anger just demonstrates fear, or even envy. I really appreciate Jain’s works. And finally.. if he’s wrong—that’s it— he is wrong.. what’s the big deal ? but if he is right —. then I can bet this rage will multiply itself— for some period of time— then it will disappear— ignorance and rage have natural and implicit limits.
