Tycho combined Copernican Theory combined Copernican Theory with Ptolemaic Theory. He believed with Ptolemaic Theory. He believed the Earth was stationary and the the Earth was stationary and the other planets orbited the Sunother planets orbited the Sun..
Johannes Kepler (1571-1630) believed in Copernicus’s idea, but he also believed that the planets move in ellipses, or oval paths.

The Phlogiston Theory, in chemistry, The Phlogiston Theory, in chemistry, was an early explanation concerning was an early explanation concerning combustion c.1700. material such as combustion c.1700. material such as coal or wood was rich in a material coal or wood was rich in a material substance he called phlogiston, from substance he called phlogiston, from a Greek word meaning "to set on a Greek word meaning "to set on fire." The actual process of fire." The actual process of combustion involved a loss of combustion involved a loss of phlogiston to the air. What remained phlogiston to the air. What remained after combustion was without after combustion was without phlogiston and could no longer burn. phlogiston and could no longer burn.
