Celestial mechanics planetary positions, using geometrical or arithmetical techniques, and contemporary discussions of the physical causes of the planets' motion. Johannes Kepler (1571–1630) was the first to closely integrate the predictive geometrical astronomy, which had been dominant from Ptolemy in the 2nd century to Copernicus, with physical concepts to produce a "New Astronomy, Based upon Causes, or Celestial Physics" in 1609. His work led to the modern laws of planetary orbits, which he developed using his physical principles and the planetary observations made by Tycho Brahe. Kepler's model greatly improved the accuracy of predictions of planetary motion, years before Isaac Newton developed
Siege of Rheinberg (1601) for two months. In November he tried to take 's-Hertogenbosch but the onset of a brutal cold winter and the threat of a Spanish relief force under Van den Bergh forced Maurice into winter quarters. Meurs stayed in Dutch hands and would remain a part of the Dutch Republic until 1712 when it became a part of Prussia. Siege of Rheinberg (1601) The Siege of Rheinberg also known as the Rhine campaign of 1601 was the siege of the towns of Rheinberg (Old Dutch: Rijnberk) and Meurs from 12 June to 2 August 1601 during the Eighty Years' War and
