[Defining media, or technologies] It makes no difference whatever whether one considers as artefacts or as media things of a tangible 'hardware' nature such as bowls and clubs or forks and spoons, or tools and devices and engines, railways, spacecraft, radios, computers, and soon; or things of a 'software' nature such as theories or laws of science, philosophical systems, remedies or even the diseases in medicine, forms or styles in painting or poetry or drama or music, and so on.
