José Leite Lopes: A imagem física do mundo: de Parmênides a Einstein. Estud. av. vol.5 no.12 São Paulo May/Aug. 1991

RESUMO

O autor discute a evolução da imagem física do mundo desde os filósofos gregos a Einstein e às idéias contemporâneas das teorias unificadas dos campos de calibre. A concepção atômica da matéria evolue da idéia de substância primordial de Tales aos leptons e quarks e aos quanta dos campos tais como gluons, bosons, vetoriais fracos e fortes. A teoria quantica é a única capaz de explicar a identidade e a estabilidade da matéria, o mundo tal como o vemos.

ABSTRACT

The author discusses the evolution of the physical description of the world form the greek philosophers to Einstein and the contemporany ideas on the unified gauge field theories. The atomic conception of matter evolves from the Thales idea of a primordial substance to leptons and quarks and the field quanta sech as gluons, weak vector basons and photons. The quantum theory is the only that can explain the identity and stability of matter, the world as we see it.

"All testing, all confirmation and disconfirmation of a hypothesis takes place already within a system. And this system is not a more or less arbitrary and doubtful point of departure for all our arguments; no it belongs to the essence of what we call an argument. The system is not so much the point of departure, as the element in which our arguments have their life."
- Wittgenstein
