Llibre: algo va mal. Radio. Etymology[edit] The etymology of "radio" or "radiotelegraphy" reveals that it was called "wireless telegraphy", which was shortened to "wireless" in Britain. The prefix radio- in the sense of wireless transmission, was first recorded in the word radioconductor, a description provided by the French physicist Édouard Branly in 1897. It is based on the verb to radiate (in Latin "radius" means "spoke of a wheel, beam of light, ray"). The word "radio" also appears in a 1907 article by Lee De Forest. It was adopted by the United States Navy in 1912, to distinguish radio from several other wireless communication technologies, such as the photophone. In recent years the more general term "wireless" has gained renewed popularity through the rapid growth of short-range computer networking, e.g., Wireless Local Area Network (WLAN), Wi-Fi, and Bluetooth, as well as mobile telephony, e.g., GSM and UMTS.

A Debate among Scholars Razmnama illustration Debate is contention in argument; dispute, controversy; discussion; especially the discussion of questions of public interest in Parliament or in any assembly.[1] Debate is a method of interactive and representational argument. Debate is a broader form of argument than deductive reasoning, which only examines whether a conclusion is a consequence of premises, and factual argument, which only examines what is or isn't the case, or rhetoric, which is a technique of persuasion. Though logical consistency, factual accuracy and some degree of emotional appeal to the audience are important elements of the art of persuasion, in debating, one side often prevails over the other side by presenting a superior "context" and/or framework of the issue, which is far more subtle and strategic.
The outcome of a debate depends upon consensus or some formal way of reaching a resolution, rather than the objective facts as such. History[edit] Forms of debate[edit] Net - Películas Clasicas.
