Having completing an engineering degree at University College Dublin and after three decades in Germany, Brian Coleman rekindled a deep interest in relativity. Four papers published in IOP’s European Journal of Physics emerged from his first efforts to untangle the standard literature’s (in parts) often confusing ‘treatments’ of basic spacetime theory. The innovative contents of these papers are explained in SPACETIME FUNDAMENTALS’ first three parts in a considerably streamlined manner.
This book also introduces an unprecedented insight leading to a radically new geometric representation of relativity acceleration scenarios: Relativistic velocity composition (addition) can be directly geometricised by a special category of (real) spherical triangles. This surprising fact is used in the book’s final chapters which (controversially) not only invalidate still widely supported Minkowski spacetime as a generalised concept, but also establish a clearcut solution to the Bell’s string paradox enigma in dispute since 1959—how does a co-accelerating ‘massless’ string between twin rockets ‘expand’ ?
This material has also expounded in three likewise peer-reviewed papers published in 2016, 2017 and 2019 in Elsevier’s peer-reviewed Results in Physics research journal. These papers have so far attracted more than five thousands academic downloads.
SPACETIME FUNDAMENTALS’ firmly focused treatment of relativity as a ‘spatio-temporal process’ reflects the author’s experience in creating and on-site commissioning artificial intelligence modules for Siemens process control systems in steel plants in Germany, Austria, Russia and Norway in the 1970s, as well as the entire logistics software for a Bosch automated machine tool complex in Moscow in 1987/8. The book’s structuring and didactic approach also owe much to the writer’s experience in the 1990s when authoring (in English) a whole series of computed tomography Somatom operator manuals for Siemens Medical Division in Erlangen.
