Kepler orbit led to Johannes Kepler working on his celestial mechanics. He later became known as the father of calculus. In 1601, Johannes Kepler acquired the extensive, meticulous observations of the planets made by Tycho Brahe. Kepler would spend the next five years trying to fit the observations of the planet Mars to various curves. In 1609, Kepler published the first two of his three laws of planetary motion. The first law states: More generally, the path of an object undergoing Keplerian motion may also follow a parabola or a hyperbola, which, along with ellipses, belong to a group of curves known
Observations and Measurements the Advancement of Hydrologic Science, Inc. (CUAHSI) and the Critical Zone Observatory project, adapts O&M. O&M is also published as a topic of the Open Geospatial Consortium "Abstract Specification". The previous version of O&M (Version 1) factored the model into two documents: Part 1 described the Observation Schema, and Part 2 described Sampling Features. Observations and Measurements Observations and Measurements (O&M) is an International Standard which defines a conceptual schema encoding for observations, and for features involved in sampling when making observations. While the O&M standard was developed in the context of geographic information systems, the model is derived from
