MODEL four-dimensional Euclidean space-time

摘要

The apparatus relates to the manuals section.; The purpose of this proposal is to provide a visual demonstration of the topology of four-dimensional Euclidean space-time.; This effect is achieved in that the model of the four-dimensional Euclidean space-time, comprising a three dimensional x, y, z and one temporary t coordinates with the reference strokes, supplemented stand cubic shape, on the upper face of which has a ball hemisphere hollow shape, in which is embedded a hollow ball of transparent material with three spatial axes x, y, z -Hard rods extending from the center of the sphere are mutually perpendicular, and time coordinates strokes represent spherical surface areas embedded in the outer balloon extending at equal intervals Δt in accordance with the differential equation Where
