Johannes Kepler bydlel v roce 1601 v dom\u011b Jakuba Kurze ze Senftenavy, kter\u00fd se nach\u00e1zel v m\u00edstech, kde dnes stoj\u00ed budovy Gymn\u00e1zia Jana Keplera. D\u016fm byl zbo\u0159en v 18. stolet\u00ed b\u011bhem terezi\u00e1nsk\u00fdch p\u0159estaveb Prahy. V dom\u011b Jakuba Kurze ze Seftenavy bydlel Kepler jako asistent a spolupracovn\u00edk Tychona Brahe. Bohu\u017eel spolupr\u00e1ce obou astronom\u016f skon\u010dila po kr\u00e1tk\u00e9 dob\u011b Tychonovou smrt\u00ed. Kepler v\u0161ak z\u016fstal v Praze a\u017e do roku 1612. Pr\u00e1v\u011b v Praze objevil prvn\u00ed dva z\u00e1kony pohybu planet, publikoval je v knize Nov\u00e1 astronomie, kter\u00e1 vy\u0161la pr\u00e1v\u011b v Praze v roce 1609. T\u0159et\u00ed z\u00e1kon (tzv. z\u00e1kon harmonick\u00fd) publikoval v roce 1619 v Linci.<\/p>\n\n\n\n
