Torricelli, energia a vapor e o sentido tecnológico da Revolução Científica

Starting from Evangelista Torricelli's pneumatic discoveries, we try to show that the crucial discoveries in pure science associated with the Scientific Revolution, although they may not have found immediate practical applications, have markedly impelled technological progress in the medium term - contrary to the diffused notion which states that the links between science and technology during the modern period have been tenuous, at best. Torricelli's ideas have turned into one of the privileged research areas for then newborn experimental program, actively participating in a process of reformulation in scientific research's epistemological base, which have culminated in steam power productive application.

Filosofia e paradigma em Cícero

Cícero é uma das poucas fontes críticas de textos do pensamento helenístico durante o período da Roma republicana. Ele atualiza a filosofia grega e, concomitantemente, reconhece a superioridade do direito romano. O espírito prático e guerreiro do povo romano afastava a filosofia, mas a emergência de novos problemas exigia reflexão. Nas disputas políticas e jurídicas, a retórica era um instrumento indispensável. O reaparecimento de estudos retóricos no século XX permitiu que alguns comentadores reconsiderassem a relação entre a retórica e a filosofia, propiciando algumas reflexões sobre o papel de Cícero na historiografia da filosofia.
