The Triangle of reference was a book published by what was often referred to as what?
Triangle of reference The triangle of reference (also known as the triangle of meaning and the semiotic triangle) is a model of how linguistic symbols are related to the objects they represent. The triangle was published in "The Meaning of Meaning" (1923) by Ogden and Richards. While often referred to as the "Ogden/Richards triangle" the idea is also expressed in 1810, by Bernard Bolzano, in his "Beiträge zu einer begründeteren Darstellung der Mathematik". However, the triangle can be traced back to the 4th century BC, in Aristotle's "Peri Hermeneias" (often referred to in its Latin translation "De Interpretatione", second book of his "Organon"). The Triangle relates to the problem of universals, a philosophical debate which split ancient and medieval philosophers (mainly realists and nominalists).
Einstein synchronisation Einstein synchronisation (or Poincaré–Einstein synchronisation) is a convention for synchronising clocks at different places by means of signal exchanges. This synchronisation method was used already by telegraphers in the middle 19th century, but was popularized by Henri Poincaré and Albert Einstein who applied it to light signals and recognized its fundamental role in relativity theory. Its principal value is for clocks within a single inertial frame.
