Math student Ken Iverson being annoyed at the inconsistency of math notation and its precedence rules decided to come up with a better one. "Iverson notation" or "the notation", he went through Harvard and became Dr Iverson, got picked up by Adin Falkoff at IBM when they were designing the IBM/360 processor and adapted the notation for the blueprints of how the thing would work, and then got rid of superscripts and subscripts and cut it down a little so it could become a line-based executable thing to run on an IBM/360 as a kind of matrix-aware desktop calculator / "A Programming Language" (APL). IBM made custom Selectric/golf-ball printer heads and keyboard overlays for it. |
