Euclidean spacetime functionalism

Spacetime and Euclidean Geometry

Using only the principle of relativity and Euclidean geometry we show in this pedagogical article that the square of proper time or length in a two-dimensional spacetime diagram is proportional to the Euclidean area of the corresponding causal domain. We use this relation to derive the Minkowski line element by two geometric proofs of the spacetime Pythagoras theorem. Introduction Spacetime dia...

A Euclidean Alternative to Minkowski Spacetime Diagram

Abstract By re-interpreting the special relativity (SR) postulates based on Euclidean 4-space-time , a geometrical model is formulated called the Euclidean Space-Time (EST) diagram. The EST diagram is a velocity vector model with a real time parameter along the 4th dimension and consequently has a (++++) metric. The model is governed by a circular function geometry and the relativistic variatio...

Colored flux tube in the Euclidean spacetime

The flux tube solution in the Euclidean spacetime with the color longitudinal electric field in the SU(2) Yang Mills Higgs theory with broken gauge symmetry is found. Some arguments is given that this flux tube is a pure quantum object in the SU(3) quantum theory reduced to the SU(2) Yang Mills Higgs theory.

Extended cognition and functionalism

Andy Clark and David Chalmers argue that the mind sometimes extends outside the body to encompass features of the environment (HEC). HEC has been criticised by Fred Adams, Kenneth Aizawa, and Robert Rupert. In this paper, I argue for two claims: (1) HEC is a harder target than those critics have supposed; HEC is entailed by functionalism, a commonly held view in philosophy of mind, and one to w...
