TIL the $ delimiters in latex were due to how expensive it was to typeset math, is this true??
Benjamin Geer@koronkebitch That’s hilarious! 😆 And it seems to be true: “Knuth explained in jest that he chose the dollar sign to indicate the beginning and end of mathematical mode in plain TeX because typesetting mathematics was traditionally supposed to be expensive.” https://en.wikipedia.org/wiki/TeX?wprov=sfti1#Operation
Whine Spectator@koronkebitch typesetting math was really hard! Only certain Monotype keyboard operators were proficient at setting "six line math". Hand-setting math was even harder.
Johannes Hostert@koronkebitch So the block-sized math used to be uber-expensive?
