El cine se desarrolló desde el punto de vista científico antes de que sus posibilidades artísticas o comerciales fueran conocidas y exploradas. Uno de los primeros avances científicos que llevó directamente al desarrollo del cine fueron las observaciones de Peter Mark Roget, secretario de la Real Sociedad de Londres, que en 1824 publicó un importante trabajo científico con el título de Persistencia de la visión en lo que afecta a los objetos en movimiento, en el que establecía que el ojo humano retiene las imágenes durante una fracción de segundo después de que el sujeto deja de tenerlas delante. Este descubrimiento estimuló a varios científicos a investigar para demostrar el principio

Armando Reverón
Nace en Caracas el 10 de mayo de 1889 poco es lo que se conoce de su niñez, de poco conocido se tiene que a los pocos años de haber nacido en Caracas fue dado en crianza por su madre a un matrimonio de Valencia, los Rodríguez Zocca, quienes se ocuparon de su primera educación. Su tío-abuelo materno, Ricardo Montilla, quien había estudiado en Nueva York, lo instruye en dibujo del natural y despierta en él su vocación artística y la cual desde niño mostró afición por la pintura. En 1904, vive con su madre en Caracas. En 1908 se inscribe en la Academia de Bellas Artes, donde tiene como profesores a Antonio Herrera Toro, Emilio Mauri y Pedro Zerpa. Su rendimiento le valió la recomendación de sus profesores para obtener, al finalizar el curso de 1911, una pensión de estudios en Europa. Este mismo año, viaja a España y se dirige a Barcelona, donde ingresa a la Escuela de Artes y Oficios. En 1912, hace un breve retorno a Caracas; de nuevo en España, entra a la Academia de San Fernando en Madrid. De acuerdo con algunos estudiosos de su vida y obra, la capital española dejó una profunda huella en su espíritu; siendo cautivado además por el universo de Francisco Goya. Más tarde, recordará su paso por el taller de José Moreno Carbonero, pintor un tanto extravagante, maestro de Salvador Dalí.
Regresa a Venezuela a mediados de 1915. Ya en Caracas, retoma su trabajo mientras asiste a las sesiones del exclusivo Círculo de Bellas Artes y abandona el rigor académico, ante el entusiasmo que despierta el impresionismo en él. Se traslada a La Guaira, en 1917, donde conoce a su modelo y compañera de vida, Juanita Ríos
Las obras de Reverón
Sus obras conocida por estar plagada de imágenes oníricas, desdibujadas, con un intenso trabajo de la luz y los colores, o la falta de ellos. Son muy celebradas también sus muñecas de trapo. Se le considera un maestro de la luz tropical, que plasmó en distintas superficies y con todo tipo de materiales. en la obra se distinguen tres periodos: período azul, período blanco y período sepia
Idustria petroquimica
Industria dedicada a obtener derivados químicos del gas. Los productos petroquímicos incluyen todas las sustancias químicas que se extraen del petróleo. La industria petroquímica moderna data del siglo XIX, y se fabrican a partir de productos no petrolíferos. La mayor parte de los productos petroquímicos se fabrican a partir de un número relativamente pequeño de hidrocarburos, entre propeno, butadieno y aromáticos
The birth of film

The two second experimental film, Roundhay Garden Scene, filmed by Louis Le Prince on October 14, 1888 in Roundhay, Leeds, West Yorkshire, England is generally recognized as the earliest surviving motion picture .
In 1878, under the sponsorship of Leland Stanford, Eadweard Muybridge successfully photographed a horse named "Occident" in fast motion using a series of 12 stereoscopic cameras. The first experience successfully took place on June 11 at the Palo Alto farm in California with the press present. The cameras were arranged along a track parallel to the horse's, and each of the camera shutters was controlled by a trip wire which was triggered by the horse's hooves. They were 21 inches apart to cover the 20 feet taken by the horse stride, taking pictures at one thousandth of a second.[1]
At the Chicago 1893 World's Columbian Exposition, Muybridge gave a series of lectures on the Science of Animal Locomotion in the Zoopraxographical Hall, built specially for that purpose in the "Midway Plaisance" arm of the exposition. He used his zoopraxiscope to show his moving pictures to a paying public, making the Hall the very first commercial movie theater.[1]
William Kennedy Laurie Dickson, chief engineer with the Edison Laboratories, is credited with the invention of a practicable form of a celluloid strip containing a sequence of images, the basis of a method of photographing and projecting moving images.[citation needed] Celluloid blocks were thinly sliced, then removed with heated pressure plates. After this, they were coated with a photosensitive gelatin emulsion.[citation needed] In 1893 at the Chicago World's Fair, Thomas Edison introduced to the public two pioneering inventions based on this innovation; the Kinetograph, the first practical moving picture camera, and the Kinetoscope. The latter was a cabinet in which a continuous loop of Dickson's celluloid film (powered by an electric motor) was back lit by an incandescent lamp and seen through a magnifying lens. The spectator viewed the image through an eye piece. Kinetoscope parlours were supplied with fifty-foot film snippets photographed by Dickson, in Edison's "Black Maria" studio. These sequences recorded mundane events (such as Fred Ott's Sneeze, 1894) as well as entertainment acts like acrobats, music hall performers and boxing demonstrations.
Kinetoscope parlors soon spread successfully to Europe. Edison, however, never attempted to patent these instruments on the other side of the Atlantic, since they relied so greatly on previous experiments and innovations from Britain and Europe. This enabled the development of imitations, such as the camera devised by British electrician and scientific instrument maker Robert W. Paul and his partner Birt Acres.
Paul had the idea of displaying moving pictures for group audiences, rather than just to individual viewers, and invented a film projector, giving his first public showing in 1895. At about the same time, in France, Auguste and Louis Lumière invented the cinematograph, a portable, three-in-one device: camera, printer, and projector. In late 1895 in Paris, father Antoine Lumière began exhibitions of projected films before the paying public, beginning the general conversion of the medium to projection (Cook, 1990). They quickly became Europe's main producers with their actualités like Workers Leaving the Lumière Factory and comic vignettes like The Sprinkler Sprinkled (both 1895). Even Edison, initially dismissive of projection, joined the trend with the Vitascope within less than six months. The first public motion-picture film presentation in Europe, though, belongs to Max and Emil Skladanowsky of Berlin, who projected with their apparatus "Bioscop", a flickerfree duplex construction, November 1 through 31, 1895.
That same year in May, in the USA, Eugene Augustin Lauste devised his Eidoloscope for the Latham family. But the first public screening of film ever is due to Jean Aimé "Acme" Le Roy, a French photographer. On February 5, 1894, his 40th birthday, he presented his "Marvellous Cinematograph" to a group of around twenty show business men in New York City.
The movies of the time were seen mostly via temporary storefront spaces and traveling exhibitors or as acts in vaudeville programs. A film could be under a minute long and would usually present a single scene, authentic or staged, of everyday life, a public event, a sporting event or slapstick. There was little to no cinematic technique: no editing and usually no camera movement, and flat, stagey compositions. But the novelty of realistically moving photographs was enough for a motion picture industry to mushroom before the end of the century, in countries around the world.The birth of film
