Sobczyk's simplicial calculus does not have a proper foundation
Alan Macdonald
The pseudoscalars in Garret Sobczyk's paper \emph{Simplicial Calculus with Geometric Algebra} are not well defined. Therefore his calculus does not have a proper foundation.
Comment on "The Cosmic Time in Terms of the Redshift", by Carmeli et al
Alan Macdonald
The time-redshift relation of Carmeli et al. differs from that of the standard flat LambdaCDM model by more than 500 million years for 1 < z < 4.5.
Entanglement, joint measurement, and state reduction
Alan Macdonald
Entanglement is perhaps the most important new feature of the quantum world. It is expressed in quantum theory by the joint measurement formula. We prove the formula for self-adjoi…
The fundamental theorem of geometric calculus via a generalized Riemann integral
Alan Macdonald
Using recent advances in integration theory, we give a proof of the fundamental theorem of geometric calculus. We assume only that the tangential derivative exists and…
