Depois de subir uma serra que parecia elevar-se do caos, o taubateano Antônio Dias de Oliveira se deparou com uma vista inebriante: uma sequência de morros enrugados, separados por precipícios e vales. No fundo desses grotões, corriam córregos de água transparente. O mais volumoso deles era o Tripuí. Foi nele que Antônio Dias encontrou um ouro tão escuro que foi chamado de ouro preto. A região, que ficaria conhecida como Ouro Preto, tinha uma formação geológica rara. Portugal tinha enfim seu Eldorado. O ouro era encontrado nas margens e nos leitos dos rios, e até à flor da terra.
Já em 1697, el-rei pôde sentir em suas mãos o metal precioso do Brasil. Naquele ano, doze navios vindos do Rio de Janeiro aportaram em Lisboa. Além do tradicional açúcar, traziam ouro em barra. A presença do metal na frota vinda do Brasil era tão inusitada que espiões franceses pensaram que o ouro era proveniente do Peru. Mas logo todos saberiam da novidade e o mundo voltaria seus olhos para o Brasil.
Como só havia dois caminhos que levavam às lavras, o trânsito de ambos se intensificou. Os estrangeiros que chegavam por Salvador ou Recife se embolavam às massas vindas do Nordeste. Juntos, desciam às minas acompanhando o rio São Francisco até o ponto em que este se encontra com o rio das Velhas, já em território mineiro. Os portugueses que desembarcavam no Rio de Janeiro seguiam o fluxo dos moradores da cidade. Em Guaratinguetá, portugueses e fluminenses agregavam-se às multidões vindas do Sul e de São Paulo e, unidos, subiam o chamado Caminho Geral do Sertão, que terminava nas minas.
Foi dessa forma desordenada e no meio do sertão bruto que pela primeira vez o Brasil se encontrou.

And Now, Robodoc!
A robot in California performs its first invasive surgery on a human patient.
Medical robots in the U.S. have been used to locate hard-to-find tumors and guide a surgeon’s scalpel, but have never actually performed surgery on people. Now that line has been crossed. At Sutter General Hospital in Sacramento, California, a 90-kg machine called Robodoc has operated on its first human patient: a 64-year-old man with a bad hip.
The robot played a key role in a total hip replacement, one of 500,000 such operations performed each year. The trick in these procedures is to create a snug hole into which the artificial hip snaps. The standard method is to jam a cutting tool into the thighbone with a handheld mallet. Robodoc, using the high-speed drill at the end of its mechanical arm, can ream a cavity that is 20 times as precise.
Robosurgery doesn’t have to stop at the hip. In Europe, where officials are less squeamish about such things, robots have assisted in operations on the brain, the prostate and the inner ear.
