Counting Is Hard

Hear me out. Mathematicians should adopt Futhark (en.wikipedia.org/wiki/Runes#Fu)

Mathematicians want new symbols like magpies want shiny things. Runes have the advantages that

1. There are not too many of them at around 24 depending on flavour.

2. Many of them correspond to a latin character in a relatively straightforward way, allowing for an additional "sort" of variables per context.

3. They can be drawn with straight lines in a way that is clear at a range of font sizes and are forgiving to those with poor handwriting (I'm looking at you, ξ)

4. They come from a dead language, so who's going to complain other than old norse specialists.

This handles many of the disadvantages of say:
Chinese characters (too many, and I know over 2000)
Hangul / Kana / etc. (multiple sensible choices for a given consonant)
Hebrew / other abjads (none that correspond to vowels)

Some problems:
1. Basically none of you know them. Consult your local tiktok fortune teller for a brief intro

2. The standard futhark order does not really correspond to latin/greek order

Edit: 3. Poor font support for Runes. They are at least assigned standard unicode codepoints in the Runic block, so this could be mitigated over time. In tex there is the "allrunes" package at least, although I have never tried it.

(This isn't a shitpost, I've brought this up at least four times this week already at MGS)

Why don't we write the logarithm like this? It feels like teaching students what logarithms are is way more painful than teaching roots, but this notation emphasizes that they are perfectly analogous.

I can provide my rough source for this if people are interested.

Five typeset equations. The first shows how squaring a number and taking its square root cancel each other out. The second shows the analogous thing for exponentiation and the logarithm, but an upside-down radical symbol take the place of the usual "log" notation. The third equation shows this also, but places a small "e" in the radical to indicate that the base is in fact Euler's number. The last two equations show the rules for how products and exponents interact with logarithms using this new notation.

TIL: "The use of the symbol ∈ (a stylized form of the Greek epsilon) to denote membership was initiated by the Italian mathematician Giuseppe Peano in 1889. It abbreviates the Greek word ἐστί, which means "is". The underlying rationale is illustrated by the fact that if 𝐵 is the set of all blue objects, then we write "𝑥∈𝐵" in order to assert that 𝑥 is blue."
- Enderton, Elements of set theory
