Is it significant that the branch point is close to the value of π? Barmar (talk) 20:28, 8 July 2024 (UTC)

I was thinking the same thing, but decided it was probably nothing worth mentioning - probably just an arbitrary starting point. *Possibly* referencing the strange appearance of π but I doubt it. Anything can be significant if you believe hard enough, anyway.--162.158.158.60 20:30, 8 July 2024 (UTC)
Keep in mind π isn't special. Most real numbers are like π. The rational numbers, and the roots of polynomials with rational coefficients (algebraic completion), are the aberration. --172.71.160.71 07:25, 10 July 2024 (UTC)

How does adding a new branch to a railway line reduce congestion? Isn't this more like a highway? 141.101.105.47 23:30, 8 July 2024 (UTC)

Read about the 2nd avenue subway. 172.70.111.168 02:22, 9 July 2024 (UTC)

I think the whole section can be removed. The point is to explain the comic, not to describe what is seen (unless it's relevant for the explanation, which, so far, seems not be the case). "Various symbols" should cover it. Elektrizikekswerk (talk) 06:35, 9 July 2024 (UTC)

The symbols seem well chosen TBH, I can totally see how they substitute for 4, 5, 6, 7, 8 162.158.146.32 14:42, 9 July 2024 (UTC)

Except that, according to the title text, they should be 4, 8, 16, 32, 64. 172.71.242.159 15:59, 9 July 2024 (UTC)
I think that the express train travels on the regular number line, so I think the second branch parallels the regular number line. Thus, 4, 5, 6, 7, 8. Sarah the Pie(yes, the food) (talk) 02:11, 10 July 2024 (UTC)

Mathematicians been there, done that: https://en.wikipedia.org/wiki/Non-standard_model_of_arithmetic Although a nonstandard model of the integers can't branch by Peano axioms. 172.71.160.71 15:08, 9 July 2024 (UTC)

Hold my beer! [Prompts Claude 3.5 Sonnet to create a non-standard model of arithmetic.]
"Here is a non-standard model of arithmetic consistent with the Peano postulates:
Axioms:
∃0, ω : 0 ≠ ω
∀x : S(x) = x + 1 if x ∈ ℕ; S(ω) = ω
Theorems:
T1. ∀n ∈ ℕ : n < ω
T2. ∀n ∈ ℕ : n + ω = ω
T3. ω + ω = ω
Lemma:
L1. ∀n ∈ ℕ : S(n) ≠ ω
"Induction" Principle:
For any property P, if P(0) ∧ P(ω) ∧ (∀x : P(x) → P(S(x))), then ∀x : P(x)
Conclusions:
C1. This model "satisfies" Peano axioms while introducing a non-standard element.
C2. Arithmetic with ω leads to paradoxical results.
C3. Use of this model may violate conservation of sanity."
Oh, no! .... Tentacled one sleeps. Ph'nglui mglw'nafh Cthulhu. Accept this new soul. 172.70.210.103 03:24, 10 July 2024 (UTC)
That is just the [later edit: positive] integers plus infinity, it should place you in the thrall of Asmodeus, not Cthulhu. 108.162.245.42
The Russell-Riemann-Cantor diagonalization applies to integers with infinity, mapping each integer to a tentacle on an Eldritch manifold. 172.70.210.53 03:59, 10 July 2024 (UTC)

Personally I would have branched off between 9 and 10, and had single character symbols for 10, 11, 12, 13, 14, and 15 so that you could do base 16 without having to use letters. Randell just lacks vision. Andyd273 (talk) 15:12, 9 July 2024 (UTC)

Letters are single character symbols! I think he should extend the number line with all the letters, getting to 36 (z) before needing any new symbolsPotatoGod (talk) 21:46, 9 July 2024 (UTC)

In my eyes they all seem like geometry or geometry-related symbols. A square, sideways pi, phi (the golden ratio), a spiral, and a triangle. That should probably be noted somewhere.--Rerere284 (talk) 18:23, 10 July 2024 (UTC)

I was thinking that the first symbol looks like a square too, so what is this stuff about a Brahmi letter instead of a square? How do we get that complicated with a square? Ianrbibtitlht (talk) 18:57, 10 July 2024 (UTC)

assuming particular mappings of the depicted symbols to phonemes, and saying "Putting these 5 phonemes together gives a word that sounds a bit like 'bisect,'" is absolutely a stretch and should be removed. --162.158.159.208 22:20, 10 July 2024

I'm rather surprised that these mathematicians have decided to subdivide each integer by 8, instead of by 10, like good metricists.172.70.86.132 08:13, 11 July 2024 (UTC)

It looks to me that the split happens just beyond 3, probably at around 3.14156... Xplora1a (talk) 13:09, 11 July 2024 (UTC)

The new branch comes up between 3 and 4, which may reference The Secret Number, a sci-fi novel in which a mathematician find a number between 3 and 4. 799571388 (talk) 07:41, 16 July 2024 (UTC)
