Humanity's 15 most important milestones 11-15
Humanity's 15 most important milestones 11-15
001 Petroleum is a naturally occurring flammable liquid found beneath the Earth's surface and has been used in one form or another since ancient times. The Babylonians used tar in the building of walls and towers over 4,000 years ago, but it would not be until 1859 of the Common Era that the first modern oil well was drilled. Edwin Drake used a steam engine to drill the well near Titusville, Pennsylvania, USA. While petroleum is used mostly as fuel, it is also important in many other industries involved in pharmaceuticals, fertilizers, and plastics. Vital to many other activities and its importance in the maintenance of civilization itself, the discovery of petroleum has certainly changed the human landscape. 002 Prior to steam power, rail transport was marginally used, the earliest known of which dates to the 6th century BCE to transport ships across the Corinth isthmus in Greece. Most were powered by either slaves or animals. The development of steam power during the Industrial Revolution spurred ideas for mobile locomotives on tracks. In 1811 John Blenkinsop designed the first practical railway and built the locomotive the following year. It ran between Middleton Colliery and Leeds in Britain. Rail transport soon exploded across Europe and North America, altering both the range and magnitude of human expansion, connecting people who were previously separate, and allowing for the relatively cheap movement of goods and passengers. Today rail transport is widely used throughout the world, and is likely to increase in usage in the future. 003 The process of developing nuclear power began in earnest with James Chadwick who discovered the neutron in 1932. With its lack of an electric charge, it was deemed to be an excellent tool for experimentation. However, it would take an additional six years before German chemists Otto Hahn and Fritz Strassmann, and Austrian physicist Lise Meitner and her nephew Otto Robert Frisch discovered fission, or the splitting of uranium atoms with the bombardment of neutrons of barium. This news quickly spread and further research began in several countries, notably the United States, Germany and the Soviet Union. 004 On December 2nd, 1942, critical mass, or criticality, was achieved under the Manhattan Project in Chicago, Illinois, USA. Today, nuclear power provides 10 percent of the world's electricity with 439 reactors operating in 31 countries. But the most important aspect of nuclear power is in the near future for space propulsion applications, as nuclear power provides about 10 million times more energy than chemical reactions in rockets. As the Space Age dawns, nuclear power will demonstrate to be integral in the next Age of Discovery.- published: 19 Aug 2013

LOCOMOTIVA - HISTÓRIA Uma locomotiva é um veículo ferroviário que fornece a energia necessária para a colocação de um comboio ou trem em movimento; as locomotivas não têm capacidade de transporte própria, quer de passageiros, quer de carga. No entanto, alguns comboios, possuem unidades (carruagens) mistas auto-alimentadas que também servem principalmente, para o transporte de pessoas; a esses veículos, no entanto, não se dá normalmente o nome de locomotiva, mas trem unidade. A Locomotiva a vapor é uma locomotiva propulsionada por um motor a vapor que compõe-se de três partes principais: a caldeira*, produzindo o vapor usando a energia do combustível, a máquina térmica*, transformando a energia do vapor em trabalho mecânico e a carroçaria, carregando a construção. O vagão-reboque (também chamado "tender") de uma locomotiva a vapor transporta o combustível e a água necessários para a alimentação da máquina. As primeiras locomotivas apareceram no século XIX sendo o mais popular tipo de locomotiva até ao fim da Segunda Guerra Mundial. No Brasil as locomotivas à vapor receberam o apelido de "Maria-Fumaça" em virtude da densa nuvem de vapor e fuligem expelida por sua chaminé. *Caldeira é um recipiente metálico cuja função é, entre muitas, a produção de vapor através do aquecimento da água. *Máquinas térmicas são máquinas que realizam trabalho e lidam com a variação de temperatura. Normalmente, as máquinas térmicas retiram calor da fonte quente e transferem-no para a fonte fria, o que define sua eficiência. Uma máquina térmica tem maior eficiência se transforma mais calor em trabalho, transferindo, portanto, menos calor na fonte fria. As máquinas térmicas utilizam energia na forma de calor (gás ou vapor em expansão térmica) para provocar a realização de um trabalho mecânico. Por isso o cilindro com pistão móvel é um dos principais componentes dessas máquinas: o gás preso dentro do cilindro sob pressão, quando aquecido, expande-se, deslocando o pistão e realizando trabalho. A primeira locomotiva a vapor usando trilhos foi construída pelo engenheiro Richard Trevithick e fez o seu primeiro percurso em 21 de Fevereiro de 1804. A locomotiva conseguiu puxar cinco vagões com dez toneladas de carga e setenta passageiros à velocidade vertiginosa de 8 km por hora usando para o efeito trilhos fabricados em ferro-fundido. Esta locomotiva, por ser demasiado pesada para a linha-férrea e avariar constantemente, não teve grande sucesso. Clique AQUI e veja o motor funcionando Funcionamento da locomotiva a vapor: Nesta animação, a cor rosa representa o "vapor vivo", procedente da caldeira, entrando no cilindro. A cor azul representa o vapor gastado que escapa do cilindo. Outro inglês, John Blenkinsop, construiu uma locomotiva em 1812 que usava dois cilindros verticais que movimentavam dois eixos, unidos a uma roda dentada que faziam accionar uma cremalheira. Esta máquina usava também trilhos de ferro-fundido, que vieram substituir definitivamente os trilhos em madeira usados até aí. Estes trilhos ou linhas de madeira tinham sido desenvolvidos na Alemanha por volta do ano de 1550, serviam carruagens que eram puxadas por animais, principalmente por cavalos mas também, por vezes, à força de braços. No entanto, o passo maior para o desenvolvimento da locomotiva seria dado por George Stephenson. Este inglês construiu a sua primeira locomotiva a quem chamou Blucher, corria o ano de 1814. A Blucher, que se destinava ao transporte dos materiais da mina, conseguiu puxar uma carga de trinta toneladas à velocidade de 6 quilômetros por hora. Stephenson viria a construir a primeira linha férrea Stockton and Darlington Railway, entre Stockton-on-Tees e a região mineira de Darlington, que foi inaugurada em 27 de Setembro de 1825 e tinha 61 km de comprimento; quatro anos mais tarde, foi chamado a construir a linha férrea entre Liverpool e Manchester. Nesta linha foi usada uma nova locomotiva, batizada Rocket, que tinha uma nova caldeira tubular inventada pelo engenheiro francês Marc Seguin e já atingia velocidades da ordem dos 30 km/hora. No início do século XIX, as rodas motrizes passaram a ser colocadas atrás da caldeira, permitindo desta forma aumentar o diâmetro das rodas e, conseqüentemente, o aumento da velocidade de ponta. O escocês James Watt, com a introdução de várias alterações na concepção dos motores a vapor, designadamente na separação do condensador dos cilindros, muito contribuiu também para o desenvolvimento dos caminhos de ferro. Depois dessa época as locomotivas passaram do vapor à eletricidade. No dia 31 de Maio de 1879, Werner Von Siemens apresentou na Exposição Mundial de Berlim a primeira locomotiva elétrica. No entanto, o seu desenvolvimento só foi significativo a partir de 1890, mantendo-se a sua utilização até aos dias atuais.- published: 17 Nov 2013
