Many of the presented equations come from Horst Thieme's book "The disenchanted electron" (original German title "Das entzauberte Elektron", ISBN 978-3-943760-39-2).

More information about overlook, ignored or dismissed physical relations can be found in my book "Physics Recombined" which is available at Amazon and (for free) at Zenodo.org.
