Francesco Zantedeschi
Francesco Zantedeschi (August 20, 1797 – March 29, 1873) was an Italian Catholic priest and physicist. Biography A native of Dolcè, near Verona, Zantedeschi was for some time professor of physics and philosophy in the Liceo of Venice. Later he accepted the chair of physics in the University of Padua, which he held until 1853 being then obliged to resign on account of failing sight. He was an ardent worker and prolific writer, 325 memoirs and communications appearing under his name in the '' Biblioteca Italiana'' and the '' Bibliothèque universelle de Genève''. Zantedeschi died at Padua in 1873. Scientific work In 1829 and again in 1830, Zantedeschi published papers on the production of electric currents in closed circuits by the approach and withdrawal of a magnet, thereby anticipating Michael Faraday's classical experiments of 1831. While carrying out researches on the solar spectrum, Zantedeschi was among the first to recognize the marked absorption by the atmosphe ...

Green
Green is the color between cyan and yellow on the visible spectrum. It is evoked by light which has a dominant wavelength of roughly 495570 Nanometre, nm. In subtractive color systems, used in painting and color printing, it is created by a combination of yellow and cyan; in the RGB color model, used on television and computer screens, it is one of the additive primary colors, along with red and blue, which are mixed in different combinations to create all other colors. By far the largest contributor to green in nature is chlorophyll, the chemical by which plants photosynthesis, photosynthesize and convert sunlight into chemical energy. Many creatures have adapted to their green environments by taking on a green hue themselves as camouflage. Several minerals have a green color, including the emerald, which is colored green by its chromium content. During Post-classical history, post-classical and Early modern period, early modern Europe, green was the color commonly assoc ...

Autobiography
An autobiography, sometimes informally called an autobio, is a self-written account of one's own life. It is a form of biography. Definition The word "autobiography" was first used deprecatingly by William Taylor in 1797 in the English periodical ''The Monthly Review'', when he suggested the word as a hybrid, but condemned it as "pedantic". However, its next recorded use was in its present sense, by Robert Southey in 1809. Despite only being named early in the nineteenth century, first-person autobiographical writing originates in antiquity. Roy Pascal differentiates autobiography from the periodic self-reflective mode of journal or diary writing by noting that " utobiographyis a review of a life from a particular moment in time, while the diary, however reflective it may be, moves through a series of moments in time". Autobiography thus takes stock of the autobiographer's life from the moment of composition. While biographers generally rely on a wide variety of documents an ...

American Philosophical Society
The American Philosophical Society (APS), founded in 1743 in Philadelphia, is a scholarly organization that promotes knowledge in the sciences and humanities through research, professional meetings, publications, library resources, and community outreach. Considered the first learned society in the United States, it has about 1,000 elected members, and by April 2020 had had only 5,710 members since its creation. Through research grants, published journals, the American Philosophical Society Museum, an extensive library, and regular meetings, the society supports a variety of disciplines in the humanities and the sciences. Philosophical Hall, now a museum, is just east of Independence Hall in Independence National Historical Park; it was designated a National Historic Landmark in 1965. History The Philosophical Society, as it was originally called, was founded in 1743 by Benjamin Franklin, James Alexander (lawyer), James Alexander, Francis Hopkinson, John Bartram, Philip Syn ...

Flame
A flame (from Latin ''flamma'') is the visible, gaseous part of a fire. It is caused by a highly exothermic chemical reaction taking place in a thin zone. When flames are hot enough to have ionized gaseous components of sufficient density they are then considered plasma. Mechanism Color and temperature of a flame are dependent on the type of fuel involved in the combustion, as, for example, when a lighter is held to a candle. The applied heat causes the fuel molecules in the candle wax to vaporize (if this process happens in inert atmosphere without oxidizer, it is called pyrolysis). In this state they can then readily react with oxygen in the air, which gives off enough heat in the subsequent exothermic reaction to vaporize yet more fuel, thus sustaining a consistent flame. The high temperature of the flame causes the vaporized fuel molecules to decompose, forming various incomplete combustion products and free radicals, and these products then react with each other and with ...

Hans Christian Ørsted
Hans Christian Ørsted ( , ; often rendered Oersted in English; 14 August 17779 March 1851) was a Danish physicist and chemist who discovered that electric currents create magnetic fields, which was the first connection found between electricity and magnetism. Oersted's law and the oersted unit (Oe) are named after him. A leader of the Danish Golden Age, Ørsted was a close friend of Hans Christian Andersen and the brother of politician and jurist Anders Sandøe Ørsted, who served as Prime Minister of Denmark from 1853 to 1854. Early life and studies Ørsted was born in Rudkøbing in 1777. As a young boy he developed an interest in science while working for his father, who owned the local pharmacy. He and his brother Anders received most of their early education through self-study at home, going to Copenhagen in 1793 to take entrance exams for the University of Copenhagen, where both brothers excelled academically. By 1796, Ørsted had been awarded honors for his papers in bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gian Domenico Romagnosi
Gian Domenico Romagnosi (; 11 December 1761 – 8 June 1835) was an Italian philosopher, economist and jurist. Biography Gian Domenico Romagnosi was born in Salsomaggiore Terme. He studied law at the University of Parma from 1782 to 1786. In 1791 he became the chief civil magistrate of Trento. In the late 18th and early 19th century Trento was successively under the rule of France, Italy and Austria. In 1799 Romagnosi was arrested in Innsbruck during fifteen months by the Austrians on account of his alleged sympathy with the French, but he was acquitted. In 1801 the French occupied Trento, and he was raised to the position of Secretary of the Higher Council. He was successively professor of law at Parma, Pavia, Pisa and Milan. After the fall of Napoleon he lost his position at the Milan university, but continued to lecture till 1817. In 1818 he was again tried for treason at Venice, and again acquitted. Carlo Cattaneo was his student and he was largely influenced by his thou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electromagnetic Radiation
In physics, electromagnetic radiation (EMR) consists of waves of the electromagnetic field, electromagnetic (EM) field, which propagate through space and carry momentum and electromagnetic radiant energy. It includes radio waves, microwaves, infrared, Light, (visible) light, ultraviolet, X-rays, and gamma rays. All of these waves form part of the electromagnetic spectrum. Classical electromagnetism, Classically, electromagnetic radiation consists of electromagnetic waves, which are synchronized oscillations of electric field, electric and magnetic fields. Depending on the frequency of oscillation, different wavelengths of electromagnetic spectrum are produced. In a vacuum, electromagnetic waves travel at the speed of light, commonly denoted ''c''. In homogeneous, isotropic media, the oscillations of the two fields are perpendicular to each other and perpendicular to the direction of energy and wave propagation, forming a transverse wave. The position of an electromagnetic wave w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
James Clerk Maxwell
James Clerk Maxwell (13 June 1831 – 5 November 1879) was a Scottish mathematician and scientist responsible for the classical theory of electromagnetic radiation, which was the first theory to describe electricity, magnetism and light as different manifestations of the same phenomenon. Maxwell's equations for electromagnetism have been called the " second great unification in physics" where the first one had been realised by Isaac Newton. With the publication of "A Dynamical Theory of the Electromagnetic Field" in 1865, Maxwell demonstrated that electric and magnetic fields travel through space as waves moving at the speed of light. He proposed that light is an undulation in the same medium that is the cause of electric and magnetic phenomena. (This article accompanied an 8 December 1864 presentation by Maxwell to the Royal Society. His statement that "light and magnetism are affections of the same substance" is at page 499.)
