The 1925 publication of Principia Mathematica caused something of a stir in academic circles back then. By firmly vesting precise mathematical notation and insisting on the precise use of language, Betrand Russell and Alfred Whitehead convinced approximately everybody in science and mathematics that it was time to stamp out ambiguity in scientific claims. Expressions and symbols like this became commonplace: ??x ???x ??x .???. (x): ??(?????) – ??(?????).
The year 1925 precedes a lot of change that has hit the world since then. The most important change is the advent and widespread use of computing devices, that is, computers.
