I've seen β„™ used for probability.

I’ve also seen β…† as the differential operator and 𝔼(X) as the expected value of X. I think I’ve also seen πŸ™_x, and β…ˆ, and β…‰ but I don’t remember for what.

I know πŸ™_X as the indicator function (also called characteristic function) of X in measure theory and probability theory, but I’ve also seen 1_X or Ο‡_X.

β…ˆ and β…‰ can be basis vectors or imaginary units although I’ve never seen them in blackboard bold in my lectures.

I see on the page there are also unicode symbols for roman numerals IX, X, and XI. I can see an argument for having a separate character for roman numeral X as opposed to just using a capital X like a normal person would, but where do they get off calling IX and XI numerals? They are two-character sequences, and adding characters for the combinations sounds like all pain and no gain.

The most sane interpretation is that Elon Musk was payed to dilute or destroy Twitter. I can't think of anything else that would make sense. Throwing 44 billion dollars on a company and then gutting it for everything that was valuable including a unique brand that had even its own verb? But the sad reality is probably that a 12 years old narcissist edgelord in the body of a billionaire wanted a vanity plate.

Seems like a reasonable theory if it's the price to be paid by those in power to avoid future revolutions. https://en.wikipedia.org/wiki/Twitter_Revolution

Or to foment one of his own ;)

I wonder what Elon paid for x.com?

I'm not sure. There was a short period when you could register one letter dotcoms before about 1994. He's owned it since forever that I know of. His first company was called X, which became PayPal. I spent a long time in the mid-90s trying to persuade INTERNIC to let me register b.com.

Shame. That would have made a great Chinese porn site. https://en.wiktionary.org/wiki/%e5%b1%84

For arguments I wanted to stick to mathematical convention like f(x) without looking like a regular variable.

I wasn't familiar with BQN. Clicked through, reminded me of APL. "OH", I thought, "I see how you came up with the name." There was a (disproven) urban legend about Arthur C. Clarke's 2001, where "HAL" was secretly a reference to "IBM", where you transpose each letter by one. H + 1 = I A + 1 = B L + 1 = M Man, BQN is a clever name. Because, A + 1 = B P + 1 = Q L + 1 = M... ...well crap. That theory didn't pan out at a…

You're not wrong though; see.. https://mlochbaum.github.io/BQN/tutorial/variable.html#modif... I guess

Off by Fibonacci, rather than off by 1, I guess.
