The simplest Friedmann models, about which astronomers were still arguing in the late nineteen fifties and sixties are dominated by the equation $${{{{\dot S}^2} + c{k^2}} \over {{S^2}}} = {A \over {{S^3}}}$$ in which Sis the scale factor of the universe, a function of the time, A is a positive constant and kis a topological factor which can be ...

1990Abstract By 1600 the European scientists were unquestionably impressed with the importance of mathematics for the study of nature. The strongest evidence of this conviction was the willingness of Copernicus and Kepler to overturn the accepted laws of astronomy and mechanics and religious doctrines for the sake of a theory which in their ...
