Problem with copypasting Latex equations into WordPress: No pasting – no posting
The main reason that I stopped posting is that copypasting Latex equations from my files into WordPress produces the message “formula does not parse”. I have to manually retype the formula in the WordPress edit window, and then Preview gives … Continue reading

On Physical Significance of Spaces with Neutral Signature
Negative Energies in Classical Theories We have seen that the Clifford space, C, is a manifold, whose tangent space at any of its points is the Clifford algebra . Its metric has the signature (8,8), which means that it can … Continue reading
“The Trouble with Physics”
It is only recently that I had the opportunity to read the book The Trouble with Physics by Lee Smolin. I liked the book, and I was pleased to find that the author discussed some issues about fundamental theoretical physics that … Continue reading

From vectors to spinors, and beyond
Spinors are usually considered as weird objects that cannot be easily understood in intuitive terms. But within the context of Clifford algebra Cl(1,3) there exist a wellknown procedure to construct spinors in terms of vectors, and their wedge products. In … Continue reading

Geometry and Physics (Part 2)
Clifford Space: An Extension of Spacetime An extended object, O, can be be sampled by a finite set of parameters, for instance, by the center of mass coordinates, and by the orientation of its axes of symmetries. Higher multipole deformations, … Continue reading
Geometry and Physics (Part 1)
Geometric Calculus Based on Clifford Algebra In 1992 I met prof. Waldyr A. Rodrigues, jr., who introduced me into the subject of Clifford algebras. We were guests of prof. Erasmo Recami at the Institute of Theoretical Physics, Catania, Italy. Until … Continue reading
