... classified between two separate branches, Euclidean and Non-Euclidean Geometry. Being based off different postulates, theorems, and proofs, Euclidean Geometry deals mostly with two-dimensional figures, while Demonstrative, Analytic, Descriptive, Conic, Spherical, Hyperbolic, are Non-Euclidean, dealing with figures containing more than two-dimensions. The main difference between Euclidean, and Non-Euclidean Geometry is the assumption of how many lines are ... mainly focused on in the preceding text was that of Spherical and Hyperbolic. There are many other Non-Euclidean Geometries which ...

... Three Laws of Planetary Motion. The orbit of planets are ellipses, with the sun at one center of the ellipse The line joining the planet to the Sun sweeps out equal areas in equal times as the planet travels around the ellipse. The ratio of the squares of the revolutionary periods for two planets is equal to the ratio of the cubes ... ...

... to circles, Kepler, by using Tycho's superb data was able to show that Mars did not move in a circular path, but rather in an elliptical one. The shape of an ellipse is described by its long and short dimension called its major and minor axes, respectively. Kepler's discoveries of the nature of planetary motions are expressed in what are known today ... from the sun. *The above drawing is a copy of Kepler's notes on the planetary movement of Mars. The following pages are Kepler's Three laws and the explanation of what an ellipse is and its parts. ********** As for Kepler's Laws, they ha...

... being tugged by more than one force, are not able to move in a circular motion. If two objects are pulling on one another, then the orbital motion must be an ellipse. In the case of our solar system, planets orbit the sun in an elliptical motion with the sun being one of the center foci that allows for the planets to ... ...

... problem. Tycho's data was the best available before the invention of the telescope and the accuracy was good enough for Kepler to show that Mars' orbit would precisely fit an ellipse. Discovering the elliptical orbits of the planets solved the problem of the planets speeding and slowing which was observed. Now there was no need for using epicycles and having a mean ... ...
