document.write(""); MALVASIA MALVACEAE, in botany, an order of Dicotyledons belonging to the series Columniferae, to which belong also the orders Tili— aceae (containing Tilia, the lime-tree), Bombaceae (containing Adansonia, the baobab), Sterculiaceae (containing Theobroma, cocoa, and Cob, cola-nut). It contains 39 genera with about 300 species, and occurs in all regions except the coldest, the number of species increasing as we approach the tropics. It is represented in Britain by three genera: Malva, mallow; Althaea, marsh-mallow; and Lavatera, tree-mallow. The plants are herbs, as in the British mallows, or, in the warmer parts of the earth, shrubs or trees. The leaves are alternate and often palmately lobed or divided; the stipules generally fall early. The leaves and young shoots often bear stellate hairs and the tissues contain mucilage-sacs. The regular, hermaphrodite, often showy flowers are borne in the leaf-axils, solitary or in fasicles, or form more ,n-..~ or less complicated cymose 14~~ ~‘~‘f arrangements. An epicalyx (see

Folk remedies, herbs, foods, micronutrients, and other substances and therapies are included as information and not as replacements for the diagnoses, advice, and treatments provided by competent wellness professionals. Sol, the star binding together our planetary family, marks summer's approach by ascending ever higher into the skies hovering above Earth's northern hemisphere. By the 21st day of June, this "luminous cloud" of Ezekiel reaches its lofty throne, reigning for but a day (albeit the longest of the year!) at this heavenly apex. Because light and warmth are so necessary for the development and maintenance of life, the summer solstice marks the beginning of the season known to overflow with a symphony of colors, a rainbow of sounds, and a joyous dance performed by an endless variety of plants and animals. Cancer Appropriately, this day also launches the zodiacal sign of Cancer (June 21-July 22), ruler of motherhood and the nurturing which accompanies the child-bearing capacity. This is the month honoring the home, the homemaker, and the family.

Le procédé en est dû au physicien Etienne-Louis Malus (1775-1812), et c'est William Hyde Wollaston (1766-1828) qui l'a rendu pratique. Sur un lourd statif est fixé verticalement un disque divisé qui porte un vernier, commandant, par une tige qui traverse le disque, une petite palette sur laquelle on fixe, avec un peu de cire ou de pâte à modeler, le cristal à examiner. On choisit à la visée un point de repère (par exemple le bord de la table sur laquelle on a posé l'instrument), puis par jeu de superpositions d'images, que l'on obtient en tournant le vernier tout en regardant à travers le cristal, on détermine, grâce aux graduations du disque, les angles du cristal. On distingue deux sortes de goniomètres: les goniomètres d'application (goniomètre d'Haüy, rapporteur sur lequel sont adaptées deux alidades, goniomètre de Brongniart) et les goniomètres à réflexion, applicables surtout aux cristaux très petits à faces brillantes. Le goniomètre de Wollaston appartient à cette dernière classe. D'autres manipluations permettent de déterminer l'indice de réfraction du cristal examiné.

Resources History of Photonics Forum Contact Us Home A Brief History of Photonics The breakthrough into what is today known as photonics came after the Second World War, initially with the invention of the transistor and the development of the semi-conductor industry. The modern photonics industry began in earnest in 1960, with the invention of the laser, followed in the late 1970's by the perfection of optical fibers as an effective means of transmitting information using these intense laser beams. During the 1960's and 1970's, these technologies remained in the research and development phases. In the next two decades, however, they moved from the laboratory into the diffusion and application phases. Until just recently, photonics was still in its infancy and much of the developmental and applications activity remained contained within large firms having predominantly other interests. Eventually - as new technologies coalesced and possibilities for products emerged - specialized divisions devoted to photonics began to form within large firms. The subsequent development of "technological paradigms" launched substantial market opportunities. Typically, independent firms then also started to appear through spin-off activity as employees left the larger, more traditional firms to form their own companies, and entrepreneurial individuals left universities and research centers to set up their own businesses, often in the same region.

~300 BC Euclid (Alexandria) In his Optica he noted that light travels in straight lines and described the law of reflection. He believed that vision involves rays going from the eyes to the object seen and he studied the relationship between the apparent sizes of objects and the angles that they subtend at the eye Probably between 100 BC and 150 AD Hero (also known as Heron) of Alexandria. In his Catoptrica , Hero showed by a geometrical method that the actual path taken by a ray of light reflected from a plane mirror is shorter than any other reflected path that might be drawn between the source and point of observation. ~140 AD Claudius Ptolemy (Alexandria). In a twelfth-century latin translation from the arabic that is assigned to Ptolemy, a study of refraction, including atmospheric refraction, was described. It was suggested that the angle of refraction is proportional to the angle of incidence Ibn-al-Haitham ( also known as Alhazen) (b. Basra). In his investigations, he used spherical and parabolic mirrors and was aware of spherical aberration. He also investigated the magnification produced by lenses and atmospheric refraction. His work was translated into latin and became accessible to later european scholars Robert Grosseteste (England).

57. Molecular Structure Light oscillating in one plane only is called polarized light. This name wasgiven it in 1808 by a French physicist, etienne louis malus (17751812). http://www.imbris.net/~jfromm/history/molecule.htm

Molecular Structure The Theory of Types Berzelius seized upon the notion that radicals could be the units of which organic molecules were built. He believed that organic molecules were built of radicals as inorganic molecules were built of individual atoms. Radicals, he came to think, were almost as indivisible and untouchable as the individual atoms themselves. Berzelius maintained that the force holding atoms together in an inorganic molecule or in an organic radical was electrical in nature (which eventually turn out to be right). Every molecule, then, had to contain a positive portion and a negative portion, since only between oppositely charged elements was there attraction. For simple inorganic substances, like sodium chloride, this notion of positive and negative was eventually shown to fit the facts. To make it fit organic substances, Berzelius had to insist that radicals consisted of carbon and hydrogen only, with carbon negative and hydrogen positive. He held that the benzoyl radical (C H O) did not and could not contain oxygen, which distorted the work done with that radical. Berzelius was also certain that it was impossible to substitute a negative element for a positive element without drastically changing the properties of a compound.

Le XIX e siècle Les Personnages François ARAGO (Estagel, 26 février 1786 - Paris, 2 octobre 1853) Par Marc Nadaux François Arago naît le 26 février 1786 à Estagel dans le pays catalan. Le village sera rattaché quelques années plus tard au département des Pyrénées orientales. Les Arago sont des paysans aisés, des " pagès ", éleveurs de brebis, cultivant à l’occasion quelques oliviers. Cette opulence locale permet à son père, François Bonaventure, d’effectuer de solides études à l’université voisine de Perpignan. Bachelier en droit, il est chargé de responsabilité municipale à la fin du règne de Louis XVI, avant de devenir le premier maire de la commune, le 7 février 1790. Quelques années plus tôt, en 1778, il s’était marié à Marie Roig, elle aussi fille de paysan aisé. Tandis que la Révolution poursuit sa marche en avant, François Bonaventure Arago devient magistrat, adhérant à la Société populaire, affiliée au Club des Jacobins. Après la déclaration de guerre à l’Espagne voisine, au mois de mars 1793, il est ensuite chargé de la levée en masse dans la région. De sensibilité girondine, ses qualités lui valent de ne pas être inquiété par la venue des représentants en mission de la Convention nationale. Plus tard, après Thermidor, Arago prend la présidence du Directoire, une charge qu’il occupe jusqu’en 1798. Il est alors nommé directeur de l’Hôtel de la Monnaie à Perpignan, ce qui apparaît comme un aboutissement à cette honorable carrière publique. François Bonaventure Arago sera fidèle au Consulat et à l’Empire. Il se consacre alors à l’éducation de ses enfants, qui doivent poursuivre cette ascension sociale du clan Arago.
