In this paper I explain Kepler's procedure for refuting the Ptolemaic-Tychonic approach to the problem of Mars, by using latitudinal observations at Mars's opposition, from Chapter 19 of the Astronomia Nova. This critique is fundamental to his reformation of the foundations of astronomy with his first two laws. Moreover, as I argue, the strategy he follows is deeply rooted in certain rhetorical considerations that he employed during the composition of his work.

开普勒对火星问题第谷方法的反驳中的地球怪癖

在这篇论文中，我解释了开普勒反驳托勒密-第谷方法来解决火星问题的程序，通过使用火星对面的纬度观测，来自新天文学第 19 章。这种批评是他用前两条定律改革天文学基础的基础。此外，正如我所论证的，他所遵循的策略深深植根于他在创作作品时所采用的某些修辞考虑。
