The origins of this issue of Tekhnema go back a couple of years when it was deemed important by members, contributors and readers of the journal to elaborate a multidisciplinary space in which philosophy, the thinking of technics and technology, the physical and life sciences, and the humanities could exchange ideas and positions on the question of energy. An issue of Tekhnema to that end was thought appropriate.
With its numerous cultivated varieties, the sweet orange (Citrus sinensis Osbeck) constitutes one of the world's most popular and recognizable fruit crops. Sweet oranges are citrus fruits (Citrus spp.), which are regarded as high sources of vitamin C (ascorbic acid) and other fruit acids. These fruits are hesperidiums, because of their fleshiness and separable rind. Physically, citrus fruits consist of forty to fifty percent juice, twenty to forty percent rind and twenty to thirty-five percent pulp and seeds. Chemically, they contain eighty-six to ninety-two percent water, five to eight percent sugars and one to two percent pectin with lesser amounts of acids, protein, essential oils and minerals (Janick et. al. 1981). Citrus fruits grow on small evergreen trees, many of which depend on root mycorrhizae (Janick et. al. 1981). Most of these C3 plants are cultivated as scions on rootstocks. All Citrus species have a diploid chromosome number of eighteen and are interfertile.

G.Binswanger and Company, an electrical goods wholesaler established in London during the 1880s by a German immigrant named Gustav Binswanger (later Byng), was the building block for GEC.
In 1886 Byng was joined by another German immigrant, Hugo Hirst, (later Lord Hirst) the 'Father of GEC' and the company changed its name to The General Electric Apparatus Company (G.Binswanger). This date is regarded as the real start of GEC.
The following year, the company produced the first electrical catalogue of its kind. In 1888 the firm acquired its first factory in Manchester for the manufacture of telephones, electric bells, ceiling roses and switches.
Here is an extensive history of the General Electric Company.

The online version of the Alexander Graham Bell Family Papers at the Library of Congress comprises a selection of 4,695 items (totaling about 51,500 images). This presentation contains correspondence, scientific notebooks, journals, blueprints, articles, and photographs documenting Bell's invention of the telephone and his involvement in the first telephone company, his family life, his interest in the education of the deaf, and his aeronautical and other scientific research. Dates span from 1862 to 1939, but the bulk of the materials are from 1865 to 1920. Included among Bell's papers are pages from his experimental notebook from March 10, 1876, describing the first successful experiment with the telephone, during which he spoke through the instrument to his assistant the famous words, "Mr. Watson--Come here--I want to see you." Bell's various roles in life as teacher, inventor, celebrity, and family man are covered extensively in his papers. The digitization of this selection of the Bell Family Papers is made possible through the generous support of the AT&T Foundation.
This site offers nearly 5,000 facsimile items from the large collection of Alexander Graham Bell Family papers. Materials include scientific notebooks, blueprints, articles and speeches written by Bell, seven photographs, more than 3,000 letters to and from Bell and members of his family, and even a few poems Bell wrote as a child. Bell's correspondence includes over 100 letters between Bell and Helen Keller or between Bell and others discussing Keller. The collection may be searched by subject, name, keyword, or series. There are over 100 series of material from aviation to radium to the telephone. Each series includes from one to 60 documents of between one and 300 pages each. The site provides a guide to the material, but no introductory or biographical essay. The site will best serve researchers who already know something about Bell, rather than those just beginning their research.

This is the home site of the Daguerreian Society, an organization. Dedicated to the history, science, and art of the daguerreotype, a 19th century mode of photography used primarily for making portrait images. The galleries include more than 40 historical daguerreotypes and 14 modern images. In addition to portraiture, the site also features some daguerreian landscapes, and each image is accompanied by a small descriptive caption as well as the date, subject, and photographer information. The site also provides an index of almost 100 20th-century texts on daggeureotypes; a bibliography of more than 300 pieces of daguerrian literature; a history of daggeureotypes by Society member Kenneth E. Nelson; a 1000-word description of the daguerreian process from an 1887 issue of the Scientific American; and an 1854 pamphlet that provides an illustrated tour of a daguerrian manufactory.
