We say very clearly, for it is true, that the mathematicians had shown the direction; but we add, for it is just to do so, that they had not explored it. Poisson had, deplorably quickly, decided its was not worth considering; and it was Foucault, without and help or assistance, who was the first to propose it.
Sabihin namin masyadong malinaw, para sa mga ito ay totoo, na ang mga mathematicians had ipinapakita ang mga direksyon; ngunit namin idagdag, para sa mga ito ay lamang na gawin ito, na sila ay hindi ito. Poisson had, deplorably mabilis, nagpasya nito ay hindi na nagkakahalaga ng isasaalang-alang; at ito ay Foucault, at nang walang tulong o tulong, na ang unang upang imungkahi ito.
