A related article that I found so interesting I could barely put it down, and helped convince me to leave Reddit and come here instead: medium.com/…/the-cargo-cult-of-the-ennui-engine-8….

Shouldn’t it be sans serif though? Low effort.

If ℕ is natural numbers and ℚ is rational numbers and ℤ is integers and ℝ is the rational numbers, what are 𝕏 and 𝕐?

Not aware of any specific usages, but maybe they're used as meta-sets. e.g. "consider a set of numbers 𝕏 and a set of numbers 𝕐 ... etc, which can't be done with the defined letters.

Unicode originally only had the double-struck letters for the defined sets ℂ, ℍ, ℕ, ℙ, ℚ, ℝ and ℤ, but the full alphabets were later added at higher code-points with "reserved" gaps where the defined seven letters would otherwise appear.

(Complex, Hamiltonian quaternions, Natural, Prime, Quotient (rational), Real and Zahlen, a German word for counting numbers, for anyone wondering.

Quick edit: Zahl is cognate with English "tell" and "tale" which are both related to "tally", believe it or not. "Recounting a tale" didn't used to mean telling(!) a story, but instead literally checking a previous count, and developed the wider sense later.

Also, ℍ not getting "ℚ" because ℚ couldn't have "ℝ" is kind of funny.).

So… Do you care to explain further or should we just sign up based on this static image you posted?

Your link is just to a picture, not to an article.

AbidanYre ,

It is concise though. You gotta give him that.
