    One could come away from this with the impression that transcendentals aren't irrational, but of course, they are. The set containing the roots of polynomials, like root 2, is the set of algebraic numbers, so the name that should have been used is the algebraic irrationals.

    There is a special number _p0, which is, by definition, equals to the minimal number of pies in power stack to make a rational number. There is an unproven conjecture, that a set _P, consisting of all numbers of power-stacked pies been rational, is finite. Some guys even claims that there are 42 members of that set.

    Pi defines (or is an expression of) Creativity. Creativity is inherent to Everything for Everything to exist ... So, if God, who could be seen as the 'Creator', wanted to calculate 'his' Pi to the last digit, God would have to spend infinite Time and still not getting there. Yep that's what Creativity does. Pretty clever stuff of God to invent Creativity ... Let it run and himself disappearing into Nothing without a trace as if he was never there ... Which actually is True😁

    Yes, very very poor clickbait indeed! - Firstly because π^π^π^π does seem like quite a lot of π. Therefore you would expect that getting a free slice or two wouldn't really be that big of a deal. - Secondly, a rather important question, which I feel wasn't covered at all: if it was raspberry, then could it be programmed to jam someone's radar, say while they are having coffee?

    I thought I could be slick by setting x=pi^pi^pi^pi and then taking log base pi (pilog) of both sides twice to "spread out" the computation. Then I just have to find x such that lp(lp(x))=36.4622..... turns out that lp(lp(x) is practically a horizontal line and getting up to 36 is an exercise in futility (I was looking at it in Desmos). Back to the drawing board.

    Well, I used Windows calc to PI^PI^PI^PI. And the answer equals 2'598'761'979'625'197,521(...), which really doesn't look like an integer. Literally a middle between two neighbor integers. Will I get an integer if I will use PI with much more precision? Sadly I can't easily check it because Windows calc doesn't understand numbers with higher precision than 31 digits after comma and JS has much lower precision.

    that sqrt(2) tower is a neat solution to a riddle: is it possible two irrational numbers say a and b are such that a^b is rational? The answer is yes. Let b be sqrt(2), we just need to find an a. Let's look at sqrt(2)^sqrt(2). If that's rational, we are done with a being sqrt(2). If it is not rational then let sqrt(2)^sqrt(2) be a and then a^b equals 2 which is rational. So we know there's such a pair but we don't know which! (BTW using much higher maths we can prove sqrt(2)^sqrt(2) but this doesn't matter for the above high school level proof.)

    Pi is the distance around a circle divided by the diameter. So I just defined pi and did not need an infinite series to do it. Trouble with mathematicians is that they are using classical physics to construct their math. Classical physics does not exist. So what is a circle ? It is a curved line drawn so that it is equidistant from a point, which is called the center. In Quantum Physics we have the uncertainty principle. So the point in the center is moving around. How do we make sure the distance to the circumference is constant? Use a light and mirror and then time the round trip. The uncertainty principle will cause small uncertainties in the time also . So the center is moving around and the radius is fluctuating. So What is a circle? No one can make one so what is it ???? You can't even define a circle , it is not possible.

      @朕是神 Cutting things in half is one of the most fundamental geometric and physical operations. Triangles are the most basic type of polygon. Right angles are one fourth of a full turn, and right triangles are key shapes. One circle can be surrounded by six others the same size. What does 5 get? The simplest 2D star with a unique shape, and the ability to be cut into either 1 and 4 or 2 and 3. Huzzah.

      @P JMU It's still ironic that scientific notation, which is supposed to be unbiased, uses a scientifically wonky base informed by culture only because of evolutionary happenstance. But it is understandable in a sense as they need to quickly relate things to what's already convenient, even if it's an anachronism. Even still, it sounds wrong as THE base for magnitude.

      @Carbon Roller Caco Because other people use 10. No number is better than another in a vacuum. Same reason why you use lightyear instead of inches to talk about astronomy, despite the calculation to change basis is trivially easy.

      @Carbon Roller Caco I guess because base 10 is the standard in scientific notation. If a star has mass x * 10^y, astronomers usually can't precisely measure x, so they don't care about. They only care about y, the order of magnitude, which they can estimate properly.

      Why do they of all people use 10, anyway? Everyone knows base 10's just a cultural bias inspired by our hands. And 3×3 squares, but those aren't that much more relevant to physics.

    But what about e^(i pi)???
