In November 1875, Thomas Edison made the sensational announcement that he had discovered a new force of nature, etheric force. It was to emerge some years later that the phenomenon Edison described was a form of wireless transmission, but Edison failed both to advance his theory and to exploit his discovery in new inventions. I contrast Edison’s approach to doing science with what he did when inventing, and also with the approach used by his principal scientific opponents. This contrast reveals (...) that he failed, not so much because he was an inventor who did science badly, but because when he ventured into scientific theory-making he abandoned key techniques that made him America’s most successful inventor. From this I argue that we can identify artefact creation processes in science that parallel the process of invention, and that Edison failed because his opponents created better artefacts.Keywords: Thomas Edison; Invention; Artefact; Experiment; Etheric force; Failure.

This paper contrasts the approach Thomas Edison used when dealing with his claim to have discovered a new force of nature, etheric force, to the approach he used to create successful inventions. It argues that he failed in this adventure into scientific theory making because an erroneous view of science led him to abandon techniques that made him America's most successful inventor. From this I develop an argument for viewing experimental science as an artefact creation process, like inventing, in which (...) two of the artefacts created are theories and demonstration experiments that support the theories.
