<span>Es el 38° elemento en abundancia en la corteza terrestre, en donde su concentración es de sólo 9 partes por millón (ppm). El nombre se lo puso el químico inglés Sir Humphry Davy, ----el mismo que aisló por primera vez al sodio, al potasio, magnesio, calcio y al bario---- después de aislarlo por primera vez en 1808. La palabra inglesa boron es una fusión de las palabras: bórax, mineral del que se extrae, y carbon (carbón), porque en estado elemental se parece a éste. El boro elemental es negro, lustroso y semiconductor, como el grafito, y muy duro, semejante al diamante (9.3 en la escala de Mohr, en la que el diamante tiene el valor máximo de 10.)</span>

‘It has been said by its opponents that science divorces itself from literature; but the statement, like so many others, arises from lack of knowledge.’ John Tyndall, 1874 Although we are used to thinking of science and the humanities as separate disciplines, in the nineteenth century that division was not recognized. As the scientist John Tyndall pointed out, not only were science and literature both striving to better 'man's estate', they shared a common language and cultural heritage. The same subjects occupied the writing of scientists and novelists: the quest for 'origins', the nature of the relation between society and the individual, and what it meant to be human. This anthology brings together a generous selection of scientific and literary material to explore the exchanges and interactions between them. Fed by a common imagination, scientists and creative writers alike used stories, imagery, style, and structure to convey their meaning, and to produce work of enduring power. The anthology includes writing by Charles Babbage, Charles Darwin, Sir Humphry Davy, Charles Dickens, George Eliot, Michael Faraday, Thomas Malthus, Louis Pasteur, Edgar Allan Poe, Mary Shelley, Mark Twain and many others, and introductions and notes guide the reader through the topic's many strands. ABOUT THE SERIES: For over 100 years Oxford World's Classics has made available the widest range of literature from around the globe. Each affordable volume reflects Oxford's commitment to scholarship, providing the most accurate text plus a wealth of other valuable features, including expert introductions by leading authorities, helpful notes to clarify the text, up-to-date bibliographies for further study, and much more.

Principal Subject

My brother, Sir Humphry Davy, appears to me to have demonstrated, in his last Bakerian Lecture, the existence of a class of bodies similar to metallic oxides, and consisting of metals in union with chlorine or oxymuriatic acid. These combinations are the principal subject of the following pages. I shall do myself the honour of giving an account of the experiments I have made to ascertain the proportions of their constituent parts, and likewise of describing some that have not yet been noticed.

The Royal Society’s first rejection of the kinetic theory of gases (1821), John Herapath versus Humphry Davy

Caloric Theory

On 24 May 1820 a manuscript entitled ‘A Mathematical Inquiry into the Causes, Laws and Principal Phenomena of Heat, Gases, Gravitation, etc.’ was submitted to Davies Gilbert for publication in the Philosophical Transactions of the Royal Society . The author was John Herapath (1790-1868), and his article included a comprehensive (if somewhat faulty) exposition of the kinetic theory of gases. Sir Humphry Davy, who assumed the Presidency of the Royal Society on 30 November 1820, became primarily responsible for the fate of the article and wrote several letters to Herapath concerning it. After it became clear that there was considerable opposition to its publication by the Royal Society, Herapath withdrew the article and sent it instead to the Annals of Philosophy , where it appeared in 1821 (1). Herapath’s theory received little notice from scientists until thirty-five years later, when the kinetic theory was revived by Joule, Krönig, Clausius, and Maxwell. The incident is significant in the history of physical science because it illustrates an important distinction between the two doctrines concerning the nature of heat—the kinetic and the vibration theories—a distinction which is often forgotten because of the apparent similarity of both doctrines as contrasted with the caloric theory. It also throws some light on the character of early nineteenth century British science, both in and out of the Royal Society.
