unlikelihood of being
The incredible unlikelihood of beingJuly 24, 2014 *[+]* (credit: iStock) Hello Ray, The universe existed several billion years before humans were conscious, and will exist several billion years after we are conscious. So, it is statistically improbable for the chronological timeline of the universe to be located at this precise moment, when we are conscious, that is, an 80 year lifespan within some 30 billion years. Are you aware of any theories, besides survivorship bias from statistics, that could address this question? Why humans happened to be alive during precise moments in the dev... mais »

missão social da educação médica
De: Francisco Arsego de Oliveira 16:41 (Há 16 horas) para saude-urbana Em setembro, participei de uma interessante reunião em Manaus, promovida pela OPAS, sobre a missão social da educação médica em busca da equidade. Saiu recentemente a página desse encontro, com as palestras e outros documentos. As melhores palestras (além da minha, é claro... hahaha) foram do Arthur Kaufman e do Daniel Blumenthal. Recomendo fortemente! O link é o seguinte: http://www.observatoriorh.org/?q=node/640
