Wavefront and ray-density plots using seventh-order matrices
Jose B. Almeida
The optimization of an optical system benefits greatly from a study of its aberrations and an identification of each of its elements' contribution to the overall aberration figures…
The null subspace of G(4,1) as source of the main physical theories
Jose B. Almeida
It is the author's belief that a perfect theory will eventually be formulated, where geometry and physics become indistinguishable, so that the complete understanding of space prop…
Euclidean formulation of general relativity
Jose B. Almeida
A variational principle is applied to 4D Euclidean space provided with a tensor refractive index, defining what can be seen as 4-dimensional optics (4DO). The geometry of such spac…
Maxwell's equations in 4-dimensional Euclidean space
Jose B. Almeida
The paper formulates Maxwell's equations in 4-dimensional Euclidean space by embedding the electromagnetic vector potential in the frame vector . Relativistic electrodynamics…
An hypersphere model of the Universe - The dismissal of dark matter
Jose B. Almeida
One can make the very simple hypothesis that the Universe is the inside of an hypersphere in 4 dimensions, where our 3-dimensional world consists of hypersurfaces at different radi…
