Discussion Overview

The discussion revolves around the labeling of the axis representing the fourth dimension in a Cartesian coordinate system. Participants explore different conventions and contexts, including mathematical and physical interpretations.

Discussion Character

  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • Some participants suggest that the fourth dimension is commonly labeled as "w," while others note that it can be labeled differently based on context.
  • One participant mentions that the fourth dimension is often associated with time, denoted by "t," particularly in physics.
  • Another participant points out that while time is a common interpretation in physics, it may not align with the mathematical context of Euclidean 4-space, where alternative notations like an indexed family of x's (i.e., x1 ... x4) might be used.
  • There is a recognition that the question may not have a straightforward answer, as the labeling can depend on the specific application or field of study.

Areas of Agreement / Disagreement

Participants express differing views on the appropriate label for the fourth dimension, with no consensus reached on a single convention. The discussion reflects multiple interpretations based on context.

Contextual Notes

The discussion highlights the ambiguity in labeling dimensions, particularly between mathematical and physical contexts, and the potential for varying conventions based on the specific application.

I have a quick question. On a typical cartesian coordinate system you have the x-axis and y-axis for two dimensions and the z-axis for the third. What would you label the axis representing the fourth dimension?

I know this is a bit of a silly and unimportant question, but I was thinking about function notation (ie: f(x), f(x,y) , f(x,y,z)) and I was wondering what would come next; f(x,y,z,?)

w is the usual convention, but you CAN call it whatever you want.
 
Fourth dimension is frequently time--denoted with letter t.

Physics frequently deals with time-like dimensions, but this isn't particularly common or useful in mathematics, and "time" as a dimension behaves differently than what the OP is asking about. When dealing with, say, Euclidean 4-space, Mandelbroth is right that w is the usual convention, but it's fairly common to just use, say, an indexed family of x's (i.e. x1 ... x4).
 
Thanks for the answer. It was bugging me because google was not being helpful.
 
Google is seldom helpful if you cannot pose a specific question- GIGO.
