12 Education Tech Trends to Watch in 2012. Revolución informática. La revolución informática es un periodo de avances tecnológicos, que abarca desde mediados del siglo XX hasta la actualidad (aunque todavía no se reconoce oficialmente, pero se habla de ella). La revolución informática está ahora en el punto donde estaba la revolución industrial en la década de 1820. Se deduce que la máquina de vapor fue para la primera revolución industrial, lo que la computadora ha sido para la revolución informática, es decir el detonante y símbolo del periodo. Hoy en día todo el mundo cree que no hay nada en la historia económica que haya progresado de manera más rápida, y que haya tenido un mayor impacto, que la revolución informática. La Ley de Moore afirma que el precio del elemento básico de la revolución informática, el microchip, cae 50% cada 18 meses.
Lo mismo que ocurrió con los productos cuya manufactura se mecanizo en la primera revolución industrial. Se dice que le revolución informática empezó con la invención de el televisor y el teléfono. Tercera revolución industrial. La tercera revolución industrial, tercera revolución científico-técnica o revolución de la inteligencia (RCT) es un concepto y una visión esbozada por Jeremy Rifkin y avalada por el Parlamento Europeo, en una declaración formal aprobada en junio de 2006.[1] A lo largo de la historia, las transformaciones económicas ocurren cuando convergen las nuevas tecnologías de la comunicación con los nuevos sistemas de energía.
Las nuevas formas de comunicación se convierten en el medio de organización y gestión que las civilizaciones más complejas han hecho posible mediante las nuevas fuentes de energía. La conjunción de la tecnología de comunicación de Internet y las energías renovables en el siglo XXI, está dando lugar a la llamada Tercera Revolución Industrial.

Ideas centrales del construccionismo[editar] El construccionismo considera además que las actividades de confección o construcción de artefactos, sean estos el diseño de un producto, la construcción de un castillo de arena o la escritura de un programa de ordenador, son facilitadoras del aprendizaje. Se plantea que los sujetos al estar activos mientras aprenden, construyen también sus propias estructuras de conocimiento de manera paralela a la construcción de objetos.
También afirma que los sujetos aprenderán mejor cuando construyan objetos que les interesen personalmente, al tiempo que los objetos construidos ofrecen la posibilidad de hacer más concretos y palpables los conceptos abstractos o teóricos y por tanto, los hace más fácilmente comprensibles. «Tomamos de las teorías contructivistas de la psicología el enfoque de que el aprendizaje es mucho más una reconstrucción que una transmisión de conocimientos.

The Gilded Age: A Tale of Today is an 1873 novel by Mark Twain and Charles Dudley Warner that satirizes greed and political corruption in post-Civil War America in the era now referred to as the Gilded Age.
Although not one of Twain's best-known works, it has appeared in more than one hundred editions since its original publication. Twain and Warner originally had planned to issue the novel with illustrations by Thomas Nast. The book is remarkable for two reasons–-it is the only novel Twain wrote with a collaborator, and its title very quickly became synonymous with graft, materialism, and corruption in public life. History of the collaboration[edit] Charles Dudley Warner, a writer and editor, was a neighbor and good friend of Mark Twain in Hartford, Connecticut. Contemporary critics, while praising its humor and satire, did not consider the collaboration a success because the independent stories written by each author did not mesh well.
Plot summary[edit] See also[edit] References[edit] Second Industrial Revolution. The Second Industrial Revolution, also known as the Technological Revolution,[1] was a phase of the larger Industrial Revolution corresponding to the latter half of the 19th century until World War I. It is considered to have begun around the time of the introduction of Bessemer steel in the 1860s and culminated in early factory electrification, mass production and the production line.
The Second Industrial Revolution was characterized by the build out of railroads, large scale iron and steel production, widespread use of machinery in manufacturing, greatly increased use of steam power, and by electrical communications. The Second Industrial Revolution saw rapid industrial development, primarily in Britain, Germany and the United States, but also in France, the Low Countries and Japan. It followed on from the First Industrial Revolution that began in Britain in the late 18th century that then spread throughout Western Europe and North America. Industry and technology[edit] Iron[edit] U.S. Belle Époque. A French poster from 1894 by Jules Chéret that captures the vibrant spirit of the Belle Époque. The Belle Époque or La Belle Époque (French pronunciation: [bɛlepɔk]; French for "Beautiful Era") was a period in French and Belgian history that is conventionally dated as starting in 1871 and ending when World War I began in 1914.
Occurring during the era of the Third French Republic (beginning 1870), it was a period characterized by optimism, peace at home and in Europe, new technology and scientific discoveries. The peace and prosperity in Paris allowed the arts to flourish, and many masterpieces of literature, music, theatre, and visual art gained recognition. The Belle Époque was named, in retrospect, when it began to be considered a "golden age" in contrast to the horrors of World War I. Popular culture and fashions[edit] It was not entirely the reality of life in Paris or in France, however. The Moulin Rouge cabaret is a Paris landmark still open for business today.

This policy describes what kinds of usernames are acceptable on the English Wikipedia, and how unacceptable or doubtful usernames can be dealt with.
It also specifies that a user account should be used only by one person, and that in most cases one person should use only one account. You choose your username when creating a user account. All contributions made using that account will then be attributed to the chosen username (contributions made while not logged in to any account are attributed to the user's IP address). It is also possible to request a change of username, and have your past contributions re-attributed to the new name. This policy applies to usernames on English Wikipedia. However in most cases you will be able to use the same username and password to log in to other language Wikipedias and other Wikimedia Foundation supported projects. See Wikipedia:Unified login.

A Documentary Film about Synthetic Biology by Field Test Film Corps. THE PROJECT Synthetic Biology is a new approach to genetic engineering. It can make E. Coli bacteria smell like fresh rain, turn sunlight into gasoline, make concrete buildings heal themselves, or goats produce spider silk in their milk. These are strange technologies certainly, but these examples help demonstrate what is possible and already happening with the tools of synthetic biology. The goal of this project is to provide an even-handed and engaging survey of current genetic engineering, and in particular, this emerging field of synthetic biology.
While there is still some ambiguity about the precise definition, synthetic biology seems to always point at a new perspective in the field of genetic science. This new perspective comes from engineers turning their attention from other fields towards biological sciences and the structures of DNA.
